Scrapes the rsyslog impstats output file and submits it to Graphite.
This was created to address the need to have a better visualization of the rsyslog impstats output. It scrapes the impstats file and processes the content into a series of graphite metrics which it them submits to Graphite. I specifically chose graphite due to the fact that it is a very powerful metric visualizer, but when you pair it with Grafana, you take the displaying of and interacting with your metrics to a whole new level.
It is important to remember that to get the most out of this script, you need to not only have it scraping the impstats file, but you have to make use of the name="" options for all of your rulesets and actions. This is important so that you can make sure that the metrics are being properly separated out. Otherwise you could end up with metrics overwriting eachother.
As you can see below, every action and ruleset has a name="" option assigned to it. This is extremely important because rsyslog uses those names in the impstats output. Rsyslog-statcollector in turn uses those labels in generating the graphite metric tree. This allows you to have a nice and organized set of metrics in graphite.
