Several times already on Habré wrote karmatrekery - showing the change in karma on the chart. The most famous and lively so far is the Habrometer . However, it wasn’t quite suitable for my purposes - a survey is 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 don’t need it, then you won’t see anything interesting under the cut: a few lines of PHP, XML parsing by standard means - for everything about everything 10 minutes. The polling frequency is standard, once every 5 minutes.

Installation

• Of course you need munin , almost any version.
• Put the plugin in / usr / share / munin / plugins /
• Specify the username inside the plugin. I did not begin to make it into a separate config - so 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.
