As previously reported in my ActiveMQ 5.9.1 RPM post, I’ve created an RPM for Active 5.9.1 on RHEL/CentOS that matches the one published on the Puppet Labs EL6 dependencies repository.
I discovered last night that I hadn’t included the new REST apis in the image. So there is now a new version. I’ve bumped the release version so that you can upgrade if you installed the previous version.
There are some significant scaling issues with ActiveMQ 5.8 and MCollective, especially around SSL connections. I’ve been working with some clients and solved many of these problems by using ActiveMQ 5.9.1 as the middleware.
I’ve created an RPM for Active 5.9.1 on RHEL/CentOS that matches the one published on the Puppet Labs EL6 dependencies repository, with the following changes:
Learning MCollective is now available in Early Release.
This has pretty much every chapter and subchapter we expect to have in the final book, but my editor and I are still polishing some rough edges. As O’Reilly says on their website:
You’ll receive updates when content is added, as well as the completed ebooks. You get free lifetime access, multiple file formats, and free updates.
So I received an e-mail from someone wanting an early access copy of the book I’m writing, by name. That wasn’t public knowledge, so it confused me. I went a-Googling, and look what I found:
Whoops, looks like the secret is out– now you know why I’ve been crazy heads down this month.
So I’ve recently been moving a bunch of hand-built RRD queries into Cacti for a customer. One of the problems I had was that none of the published templates for the ITWatchdogs Goose units worked, either due to missing XML files, old OIDs, or just plain incorrect setup in the template.
I’ve built a new template by hand and it now finds internal sensors, external temp sensors, and external airflow sensors for you. If you examine the XML files included and compare to the MIB you could easily add more of the sensors.
Installation is easy: (obviously replace
/usr/share/cacti with your installation directory)
tar xvzf itwatchdogs-goose-cacti-template.tgz
mv *.xml /usr/share/cacti/resources/snmp_queries/
Then Import the template into Cacti, and start defining your devices!
