Redis is an in-memory key-value data store that provides a small number of primitives suitable to the task of building monitoring systems. As a lot of us are hacking in this space I thought I’d write a blog post summarizing where I’ve been using it in a little Sensu like monitoring system I have been Read More
Justin and I have recently started using Zabbix for monitoring, in place of Nagios. We’ve also taken the opportunity to start collecting even more metrics than before.
One nice thing about Zabbix is that it can use pre-existing Nagios monitoring plugins out of the box. But what if you also want to collect metrics from say, a Ruby process? You’re in luck! Zabbix can collect various forms of information (from numerical metrics to arbitrary strings, to log data) via the Zabbix sender protocol. Let’s set this up.

I have couple hundred Dell systems with LSI RAID arrays however we lacked hardware monitoring which would occasionally result in situations where there would be multiple disk failures that would not get caught. Some time ago I read this post about using MegaCli to monitor Dell’s RAID controller http://timjacobs.blogspot.com/2008/05/installing-lsi-logic-raid-monitoring.html One thing I did not like [...]
On Twitter Grig Gheorghiu posed a number of questions about monitoring tools and what he wants in a monitoring tool. This is my attempt at describing what my setup looks like or has looked like in the past. 1. Metrics acquisition / performance trending I use Ganglia to collect all my metrics including string metrics. [...]

I am a big believer in adding context to alerts. This allows the recipient of an alert to make a better decision on how to deal with an alert. It’s often hard to classify alerts so providing as much context to the alert is extremely helpful. For instance if I am alerting on a value [...]
In our environment we use NFS on Netapp fileservers a lot. They are used for home directories, build directories (don’t ask), DB data directories etc. This is done mostly for reliability and data integrity. However it leads to a number of problems since they are shared by a number of different groups of users and [...]

In past articles we have covered some of basics of Sensu handlers. A nice feature we haven't touched on yet is handler "sets". Handler sets were added around v0.9.2 and can be quite useful for saving time when modifying your handler. For example, consider you have a standard set of handlers that you assign to [...]
