Several times already on Habré wrote karmatrekery - showing the change of karma on the chart. The most famous and lively so far - Habrometer . However, for my purposes, it was not quite suitable - the survey was too rare, once a day (however, in accordance with the old rules for using the Habr API, a mass survey with a higher frequency is difficult).

So I wrote my tiny munin plugin for habr. If you do not need it, then you will not see anything interesting under the cut: a few lines of PHP, parsing XML using standard tools - for everything about 10 minutes. Poll frequency - standard, once every 5 minutes.

Installation

• Needless to munin , almost any version.
• Put the plugin in / usr / share / munin / plugins /
• Specify the username inside the plugin. I did not make it into a separate config - only more work for everyone.
• Make a symlink on it in / etc / munin / plugins
• chmod a + x habracarma
• Restart munin-node

I hope someone will find it useful.
