SEC - open source and platform independent event correlation tool

Sun, 07 Mar 2010 15:48:24 GMT

Small Unix tool to find event correlations. It isn't doing data mining to find correlations in a data stream, but rather you write rules like "tell me if X happens within Y seconds of a Z" and it takes events on stdin and emits correlations on stdout.

Clarity - web app for access to log files

Sun, 13 Dec 2009 16:01:01 GMT

At Shopify we use syslog-ng to have a centralized logging server which collects all the logs from the various machines in our cluster and combines the log files together. We used to give everyone access to this box for log analysis but as we grew this became a bit impractical. To solve this, we created Clarity, which provides a very nice web interface for the two staple tools of log analysis: grep and tail -f.

How Complex Systems Fail

John Allspaw: "Let me start with this: I don’t think I can overstate how right-on this paper is, with respect to the challenges, solutions, observations, and concerns involved with operating a medium to large web infrastructure. I found this via @benjaminblack, and I agree with him 100%: this should be considered required reading for anyone in our industry. I’m not sure if Cook ever thought that his paper would apply to web infrastructure, but I think it can and does."

Djagios - an open source Nagios web based configuration tool

Fri, 30 Oct 2009 20:21:32 GMT

The main goal of the tool was to make Nagios usable for non-Nagios admins. The initial install and configuration would have to be done by Nagios administrators. But once done ordinary users can add servers, appliances, devices, services themselves. The second goal is to provide a complete developers API towards the Nagios configuration. The default functionality can be used as a template for your own design/functionality.
