puppet-graphite_event

Description

A puppet report processor for sending events to a graphite server.

This report processor will send the number of changes made during a puppet run into a graphite server. The data can then be overlaid onto other metrics to help correlate events. Use the drawAsInfinite() function in graphite to draw the events as vertical lines.

For example, in the diagram above the load average from a group of servers is plotted. Blue vertical lines mark a point in time when puppet modified resources on a host in the group. We can see that immediately following a puppet change the load spiked on one of the servers. This can be very valuable information.

Additional information on how and why to use graphite to track events can be found in Etsy's Measure Anything, Measure Everything paper.

This module is only meant to send change events to graphite. If you would like to send all metric data to graphite, please see puppet-graphite by Naresh V.

Requirements

Puppet. (Only tested on 2.7 but likely works on 2.6 and possibly 0.25)
A graphite server^

Installation & Usage

Install puppet-graphite_event as a module in your puppet master's module path (eg: /etc/puppet/modules/puppet-graphite_event)
Copy the included graphite_event.yaml to your puppet master's config dir (eg: /etc/puppet/). Then update the graphite_server, graphie_port, and path_prefix variables.

Metrics sent to graphite will use the path: <path_prefix>.fqdn_with_underscores.

Enable pluginsync and reports on your master and clients in puppet.conf

[master]
report = true
reports = graphite_event  # can specify multiple: `store, graphite_event`
pluginsync = true

[agent]
report = true
pluginsync = true

Restart your puppet master.

Masterless puppet

I suspect this could also be used in a masterless puppet setup as well, just make sure to deploy the report and config file to each client. If you have success with this please let me know by leaving a comment in the github issues section.
