Spamcop Blacklists Sourceforge Mailing List Servers

Wednesday, March 29th, 2006

If you use Spamcop, you have probably been removed from any OpenNMS mailing lists, as they decided that Sourceforge was a spammer and bounced any e-mails that were sent.

(sigh)

You will not be able to receive Sourceforge mailing list mail for at least 21 hours (unless they get their act together and delist them sooner), but afterward please feel free to resubscribe. You should be able to check to see when Spamcrap has decided that Sourceforge is okay.

I know spam is bad. I hate spam. I get at least a hundred messages a day that make it past my filter, but acting like torch wielding villagers and automatically shutting down all traffic from a particular IP address is not the way to solve the problem.

RTC Improvements

Saturday, March 25th, 2006

As OpenNMS is enterprise-grade, the goal is to be able to monitor tens of thousands of devices. While I can’t speak for the community as a whole, at the OpenNMS Group we have a couple of clients in the 40,000 device range on a single server.

We are working with one of them in Geneva, and we ran into a problem. With 40K+ nodes and 29 categories, the Real Time Console (RTC) was taking almost 4 hours to start. David and Matt went to work on optimizing the code, and they were able to show some improvement:

Previous RTC code init time: 3 hours 47 minutes

Current RTC code init time: 1 minute 19 seconds

w00t!

This is in HEAD now, but I am going to see about porting it back to stable.

Italian Adventures

Friday, March 24th, 2006

One of the things I love about this project is that it is global. We’re located in North Carolina, and I live in a small town, so I am amazed that we have had contributions to OpenNMS from all over the world. The commercial side of OpenNMS has customers in 10 countries, and the project has been invited to participate in the .org Pavilion at LinuxWorld Korea in Seoul this June (still looking for Korean-speaking OpenNMS users to help out in the booth [grin]).

Next month I’m in the UK for a week and I’ve decided to visit Europe the following week to meet up with some of the people who are doing great things with OpenNMS. One of those is Antonio Russo in Naples. He is the main contributor to the Italian-Adventures branch in CVS that includes inventory, Cisco configuration management, topology and map (yes, map) improvements.

New Blog Day

Thursday, March 23rd, 2006

Okay, here’s the new home of the OpenNMS blogs. Please check out the Blogroll on the right side for other blogs by the OpenNMS development team and other open-source related sites. If you develop on OpenNMS and want a blog, just drop me a note.

I think I have successfully retrieved my posts from both the old Bitweaver blog and the even older Moveable Type blog. Let me know if you see something wonky.
