Early/Often on the Horizon

Lots of stuff, and I mean lots of cool stuff is going on and to paraphrase Hamlet I have not enough thoughts to put them in, imagination to give them shape, or time to act them in. I spent this week in the UK but I should be home for awhile and I hope to catch up.

But I wanted to put down a at least one thought. When we made the very difficult decision to split OpenNMS into two products, Horizon and Meridian, we had some doubts that it was the right thing to do. Well, at least for me, those doubts have been removed.

It used to take us 18 or more months to get a major release out. Due to the support business we were both hesitant to remove code we no longer needed or to try the newest things. Since we moved to the Horizon model we’ve released 3 major versions in six months and not only have we added a number of great features, we are finally getting around to removing stuff we no longer need and finishing projects that have languished in the past.

In the meantime we’re delivering Meridian to customers who value stability over features with the knowledge that the version they are running is supported for three years. Seriously, we have some customers upgrading from OpenNMS 1.8 (six major releases back) who obviously want longer release cycles, and even if you don’t need support you can get Meridian software for a rather modest fee coupled with OpenNMS Connect for those times when you really just need to ask a question.

Anything OpenNMS does well is a reflection on our great team and community, but I take personally any shortcomings. At least now I can see the path to minimize them if not remove them completely.

It’s a good feeling.

OpenNMS 16 Released

In keeping with our new Horizon release policy of a new major release every three to four months, we are happy to announce the availability of OpenNMS 16, codenamed Daredevil.

Most of the changes in OpenNMS 16 are under the covers. We are trying to streamline the code and thus have removed both capsd (which was deprecated) and linkd (which was replaced by enhanced linkd). This version also requires Java 8.

The main visible feature is that the Dashboard has been rewritten and should be a considerable improvement to those who use it.

Review: System 76 Sable

As you might guess, I am a big fan of all things open, and I tend to vote with my wallet. When the need arose to replace some iMacs in the office, I decided to check out the Sable systems offered by Linux-friendly vendor System 76.

System 76 was a sponsor at SCaLE this year (like OpenNMS) and they also sponsored the Bad Voltage Live event where they gave away a laptop and a server, so they already had my goodwill.

Back in 2008 I needed some machines for our training courses, so being an Apple fanboy at the time I bought iMacs. Outfitting training rooms can be problematic if you don’t do training full time because you usually end up with nice systems that you don’t use very often. Seems wasteful, so we decided to use them to run Bamboo and our unit tests for OpenNMS when they weren’t being used for training.

Seth noticed that it was taking those machines around 240 minutes to run the suite of tests versus 160 minutes for the newer iMacs we were using, and this was having a negative impact development (almost everything we do relies on test driven development). Since we were running Ubuntu on the boxes anyway, I decided on a Linux alternative and chose System 76 for the first six replacement systems.

I like all-in-one systems for training since they tend to move around (we use the training room as a conference room when there are no classes). The all-in-one form factor makes them easy to carry. The Sables I ordered came with a 23.6 inch touch screen at 1080p, 3.1 GHz i7 processor, 16GB of RAM and a 500GB SSD for a total price of US$1731.

The ordering process went smoothly (there was one glitch when the original quote was for seven instead of six but it was quickly corrected). I placed the order on March 18th and they shipped a week later on the 25th.

They arrived in six boxes marked AIO PC:

System 76 boxes

I think AIO must be the manufacturer in China, but I couldn’t find a similar system on the web. One box had a smashed-in corner, so I opened it first, but it was packed well enough that the unit wasn’t damaged:

System 76 open box

I removed the packing and pulled the unit out. It was wrapped to protect the screen.

System 76 screen wrap

and the whole unit was covered in plastic wrap to prevent scratches.

These units come with a power brick that is external to the system and I ordered them with a Logitech keyboard and mouse. These came in a separate box along with extra cables, etc., for expansion (unlike Apple products, you can actually work on these systems).

System 76 keyboard box

The hardest part about the whole process was figuring out how to turn the darn thing on. I finally found the switch on the back of the system on the lower right side (as you face it). I felt kind of stupid and yes, I even read the little pamphlet that came with it. Perhaps they should add and IKEA-like drawing with the little dude pointing to the switch.

It booted right up into Ubuntu 14.10, and all I had to do was create an account and set the IP address. Ben was then able to get in and deploy our Bamboo image and we were up and running in no time.

System 76 screen

While we still have some iMacs being used, the Sables have, so far, proven to be a solid replacement. I haven’t really used them as a desktop, yet, but they can run our test suite in a little over an hour which is almost a four-fold increase.

System 76 in a line

While Apple doesn’t offer a 24-inch iMac anymore, the 21-inch version with similar processor, RAM and SSD is US$2399, or quite a premium. The Sable is not nearly as thin or stylish as the iMac, but it is a nice looking machine and after struggling this week to correctly replace the hard drive in a late 2009 iMac I appreciate the fact that I can work on these if I need to, and the extra cables shipped with it even encourage me to do so.

And that’s what open is all about.

♫ To Be Thick as a Brick ♫

In keeping with the musical theme this week, I thought it would be cool to post about a little bit of OpenNMS “bling” now featured at the Chatham County Public Library in Pittsboro, NC.

OpenNMS Brick

We like to both talk about OpenNMS as well as support the local community, so when I found out that the library was raising money by selling personalized bricks, I thought it would be cool to get one.

OpenNMS Brick

We also have one to be installed at the Tesla Museum. I’m going to have to take a road trip to get a picture of that one, or see if Jeremy Garcia will drive over when it is open and take one for us.

OpenNMS at Fifteen

It was fifteen years ago today that the OpenNMS Project was registered on Sourceforge.

OpenNMS Sourceforge Summary

The project itself was started sometime in 1999, but I wasn’t around then as I didn’t get involved until 2001. I’ve been told that it started in July of that year, but since an open source project really doesn’t exist until something gets shared, it seems that March 30, 2000, is as good a day as any to mark the birth of OpenNMS.

I went poking around on the site and wasn’t able to find the very first thing posted there. I believe it was a mockup of an administration console using the Java Swing toolkit that never actually made it into the product. While I believe the code is still in there somewhere, in switching from CVS to SVN to git, dates do get a little corrupted and I couldn’t find it.

Anniversaries don’t really mean that much in practical terms. In moving from Sunday, March 29th, to Monday, March 30th there was no substantial change in OpenNMS at all. But it does lend itself to a bit of reflection, and fifteen years is a lot of time on which to reflect.

While I have been working on OpenNMS most of my professional career, I didn’t start it. People much smarter than me did, and that has pretty much been the story of my life. My only true talent is getting intelligent and creative people to work with me, and the rest of my career is just basking in their reflected glory. In 2002, the original founders decided to stop working on the project, but I saw its potential and was able to become its maintainer.

My original plan was to simply remain a company of one and provide consulting services around OpenNMS. That didn’t work out so well, as I soon realized that it could be much bigger than one person. In September of 2004, The OpenNMS Group was born in part to insure that the OpenNMS platform would always be around. We wanted to build something amazing, and this was reflected in our goal “to make OpenNMS the de facto management platform of choice.”

Being pretty much a group of technical people, we didn’t know we were doing things wrong. For a business plan we chose “Spend less money than you earn.” For a mission statement we liked “Help Customers – Have Fun – Make Money”. I put forth my two desires that OpenNMS should never suck and that OpenNMS should always be free software. We just took it from there.

This is not to say that we haven’t met with frustration. Gartner likes to diagram companies on two axes: “Vision” and “Ability to Execute that Vision”. We have a lot of vision, but our business model doesn’t give us a lot of resources to execute that vision quickly.

In order to change this, I spent a lot of time in Silicon Valley looking for an investor. Silicon Valley is pretty much the center of the technology industry, and one would assume that they would know the best way to run a technology based business. But I was pretty much told that you can’t be anyone unless you work in the Valley, you’re too old, and most importantly, you are doing it wrong.

There seems to be a formula they like out there. You raise a bunch of money. You hire as many people as fast as you can. You get as many users as possible and you hope that some larger company will buy you out. They call this an “exit strategy”, and this is supposed to be the focus of the business. Once you “exit” you can do it all again.

The problem, as I see it, is that a lot of companies have to exit before they get bought out. They run out of money, the investors run out of interest or patience, and then they just shutter the endeavor. Sure, you have your prominent billion dollar acquisitions, but in the scheme of things they are a very, very small percentage.

Plus, I’m already doing what I love to do. I really don’t want to do anything else. My chosen field, network management, is huge and I can always find something interesting in it, such as figuring out the best way to deal with the Internet of Things.

Sure, I believe that there are companies out there that would complement what we do. Ones that have the capital to help OpenNMS grow in a way that doesn’t go against our corporate culture. And while our involvement with such a company would probably be through an acquisition, I don’t see that as much as an “exit” as an evolution. I wouldn’t do the deal if I didn’t think I’d want to continue to work on the project, so I wouldn’t be going anywhere.

I see this post has become more about the business side of OpenNMS than the project itself, but I felt it was important to think about how our business philosophy permeates the project. Thus I thought it was serendipitous that Ben sent me a link to an article about an alternative to the “exit strategy” called the “exist strategy”.

The Nishiyama Onsen Keiunkan is the world’s oldest business. It is a hot springs hotel in Japan that was founded in 705 and has been run by fifty-two generations of the same family. They have survived and even thrived for 1300+ years by having a relentless focus on their customers. Even though they have only 40 rooms, by any measure you have to call their undertaking a success.

I think there is a huge problem with the tech industry’s focus on the exit. It’s such a short term goal. I expect the goal we set for OpenNMS to take the rest of my life and maybe some time after that. By focusing on an exit the people who usually end up paying for it are your customers, and that just doesn’t strike me as a way to run a business. I’m certain that if the Nishiyama Onsen Keiunkan had focused on growth over service they would have died out a long time ago. Heck, even the company that started OpenNMS closed its doors in 2004. When they weren’t moving fast enough toward their goal for the investors, the did what today we would call “a pivot” and it didn’t work out, even thought that’s what anyone in the Valley would have said was the right decision.

Look, I don’t want to come across as some sort of holier than thou “money is evil” kind of person. I run a business, not a charity. But as a businessman, and not a gambler, I truly believe that our best chance at financial success is to find a way for us deliver the best value we can to our customers. Period. That’s our focus, and any type of “exit” is way down on the list. Heck, the current management team at The OpenNMS Group is ten years older than the rest of the guys, and we’ve even thought of selling the business to them when we wish to retire. Not sure we can do it 52 times, but that is one form of exit that is still in line with an “exist strategy”.

And that’s the thought I want to take into the next fifteen years of OpenNMS. We have a covenant with our users and they have paid us back in kind with their support. This has resulted in a number of other impressive numbers. The OpenNMS Group has prospered for more than a decade. We are getting ready for our tenth OpenNMS Developers Conference, Dev-Jam. We’ve had almost the same number of OpenNMS User Conferences, the next one is in September and hosted by the independent OpenNMS Foundation.

We still have quite a few years to go to match the numbers of the Nishiyama Onsen Keiunkan, but I think that focusing on an “exist strategy” is the way to go. We still have the greatest team of people ever assembled to work on a software project, and while the faces and names have changed over the years, I still feel like I’m standing on the shoulders of giants.

And the view is great from up here.

OpenNMS Horizon 15.0.1 Released

Just a quick note to let everyone know that OpenNMS 15.0.1 has been released. This is the first bug fix release for OpenNMS 15, and if you are running it I strongly suggest you upgrade.

As we are working to complete our transition to Hibernate (which will allow OpenNMS to use any database backend, not just PostgreSQL) we discovered an old issue where, under certain circumstances, duplicate outage records could be created. When this happened under the new code, it would cause an exception and the outages would never be cleared. This has been corrected.

The complete list of changes is as follows:

Bug

  • [NMS-7331] – Outage timeline does not show all outages in timeframe
  • [NMS-7392] – Side-menu layout issues in node resources
  • [NMS-7394] – Outage records are not getting written to the database
  • [NMS-7395] – Overlapping input label in login screen
  • [NMS-7396] – Notifications with asset fields on the message are not working
  • [NMS-7399] – Surveillance box on start page doesn't work
  • [NMS-7403] – Data Collection Logs in wrong file
  • [NMS-7406] – Incorrect Availability information and Outage information
  • [NMS-7409] – Visual issues on the start page
  • [NMS-7423] – Duplicate copies of bootstrap.js are included in our pages
  • [NMS-7425] – Poller: start: Failed to schedule existing interfaces
  • [NMS-7426] – Not monitored services are shown as 100% available on the WebUI
  • [NMS-7427] – The PageSequenceMonitor is broken in OpenNMS 15
  • [NMS-7432] – Normalize the HTTP Host Header with the new HttpClientWrapper
  • [NMS-7433] – Topology UI takes a long to load after login
  • [NMS-7434] – Disabling Notifd crashes webUI
  • [NMS-7435] – The Quick Add Node menu item shouldn't be under the Admin menu
  • [NMS-7437] – The default log level is DEBUG instead of WARN on log4j2.xml
  • [NMS-7452] – CORS filter not working
  • [NMS-7454] – Netscaler systemDef will never match a real Netscaler

Enhancement

  • [NMS-7419] – Read port and authentication user from XMP config
  • [NMS-7438] – Apply the auto-resize feature for the timeline charts

Welcome to OpenNMS 15

Today OpenNMS 15 was released. It was a year and a half between the release of OpenNMS 1.12 and OpenNMS 14, but only three months between OpenNMS 14 and OpenNMS 15.

As we move forward this year we are trying to adhere more to the open source mantra of “release early, release often”, and thus the new major release. There have been 1177 new commits since 14.0.3

You’ll also notice that this version of OpenNMS has a new name – Horizon. We’ve always thought that OpenNMS represents the best network management platform available and the name is meant to reflect that. We hope to make as many improvements we can, as fast as we can, without sacrificing quality, thus keeping OpenNMS out on the “horizon” from the competition.

The main improvement for the 15 release is in the webUI. Although you might not notice it at first, we’ve spent months migrating the whole interface to a technology called Bootstrap. The Bootstrap framework allows us to create a responsive UI that should look fine on a computer, a tablet or a phone. This should allow us a lot more freedom to modify the style sheet and we hope to be able to add “skinable” theme options soon.

A cool feature that can be found in this new UI is the ability to automatically resize resource graphs. If you have a particular set of resource graphs displayed:

and then you shrink the window, you’ll note that the menu turns into a dropdown and the graphs themselves now fit the more narrow window:

There are a number of bug fixes and other new features, and a complete list can be found at the bottom of this post or in our Jira instance (but for some reason you have to be logged in to see it). I am happy to say that there was no need for major security fixes in this release. (grin)

Important Security Issue with OpenNMS

It is said that “given enough eyeballs, all bugs are shallow”, which is true, but the tricky part is finding enough eyeballs, especially useful ones and not the ones in that jar in Blade Runner.

Recently, an end user reported a rather severe security issue with OpenNMS.

The process that serves up the “Categories” section on the front page of the web interface is called RTC (for Real Time Console). The database queries that create the availability numbers on that page can be expensive in terms of resources, so the RTC daemon was created to periodically query the database and then cache the results so that lots of users wouldn’t create an undo load on the system.

We use a tool called Castor to process XML data within OpenNMS. Due to a bug in Castor, if Castor discovers an error when processing an XML file, it can throw an exception that includes the contents of the file.

This is very useful when the files relate to OpenNMS and you are trying to debug them, but you don’t exactly want the contents of /etc/shadow or /etc/passwd displayed indiscriminately. That’s exactly what this exploit allows.

Since the default username and password for the RTC user is “rtc” and exists on every system, a malicious person could use that information to obtain the contents of any file on the system. Note that as far as the OpenNMS application is concerned, the RTC user has very limited permissions, but this is caused by an issue with Castor and it has just
enough permissions to trigger it.

This has been reported as our first ever CVE: CVE-2015-0975

The best fix is to upgrade to OpenNMS 14.0.3. If, however, you are unable to upgrade soon, you can edit the Spring security file to limit requests from RTC to just the localhost, which should mitigate most of the issue. Full instructions and files can be found on the wiki.

To summarize, all versions of OpenNMS prior to 14.0.3 contain a bug where *anyone* with access to the webUI (port 8980 on the OpenNMS server) can retrieve any file that is on the system. While this isn’t the end of the world, it definitely could be considered bad and should be addressed.

OpenNMS 14.0.2 Released

Today we released version 14.0.2 of OpenNMS. It is a recommended upgrade for all OpenNMS 14 users because is addresses a memory leak caused by the version of Vaadin we were using.

Test Driven Development

One of the things that bothers me a lot about the software industry is this idea that proprietary software is somehow safer and better written than open source software. Perhaps it is because a lot of people still view software as “magic” and since you can’t see the code, is must be more “magical”. Or perhaps is it because people assume that something you have to pay for must be better than something that is free.

I’ve worked for and with a number of proprietary software companies, so I’ve seen how the sausage is made, and in some cases you don’t want to know. Don’t get me wrong, I’ve seen well managed commercial software companies that produce solid code because in the long run solid code is better and costs less, but I’ve also seen the opposite done simply to get a product to market quickly.

With open source, at least if you expect contribution, you have to produce code that is readable. It also helps if it is well written since good programmers respect and like working with other good programmers. It’s out there for everyone to see, and that puts extra demands on its quality.

In the interest of making great code, many years ago we switched to the Spring framework which had the benefit that we could start writing software tests. This test driven development is one reason OpenNMS is able to stay so stable with lots of code changes and a small test team.

What’s funny is that we’ve talked to at least two other companies who started implementing test driven development but then dropped it because it was too hard. It wasn’t easy for us, either, but as of this writing we run 5496 tests every time something changes in the main OpenNMS application, and that doesn’t include all of the other branches and projects such as Newts. We use the Bamboo product from Atlassian to manage the tests so I want to take this opportunity to thank them for supporting us.

OpenNMS 14 contained some of the biggest code changes in the platform’s history but so far it has been one of the smoothest releases yet. While most of that was due to to the great team of developers we have, part of it was due to the transparency that the open source process encourages.

Commercial software could learn a thing or two from it.
