Monitoring Drupal with Sensu

I gave a presentation called Monitoring Drupal with Sensu at DrupalCorn 2013.

Installing sensu-admin on RHEL6

Sensu-Admin is a nice GUI for the Sensu monitoring framework. However, installing it on Red Hat Enterprise Linux 6 ends in pain, since RHEL6 comes with an older version of ruby (1.8).

You might be creative and get most of the required gems installed but ultimately there will be gems that simply require ruby 1.9:

Solved: Apple Mail, Smart Mailboxes, and Exchange Junk Email

One of the nice features of Mail, the bundled OS X mail client, is Smart Mailboxes. A smart mailbox is a filtered view of your mail based on your own criteria.

I have both IMAP and Exchange accounts and use Mail for both.

Installing rpy2 2.3.x and numpy on RHEL6

R from EPEL has been updated to version 3.

We would like to run rpy2 but as of rpy2 version 2.3.x, it requires Python 2.7.

Red Hat Enterprise Linux 6 comes with Python 2.6.

So we need Python 2.7 so we can use rpy2 2.3 so we can use R 3.

The solution is to create a Python virtualenv containing Python 2.7 and install rpy2 in there. That way a user can log in and get Python 2.7 when they type python at the command line.
