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.
My first blog post for Taos was just published: http://www.taos.com/2014/02/27/choose-security-partners-carefully/
This post covers the reality of security products: you can’t buy trust. Or as seems to have occurred this time, someone might be paying more than you to ensure your crypto is weak. You have to acquire the talent to ensure what you are using meets your needs.
I suspect that readers of this blog might point out that my summary has always been true: nobody should ever have trusted RSA blindly. My target audience for that post is people who may not have realized this before.
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!
