Heimon - Furcadia Heimdall Monitoring Service

Description

This is a small recreational project I made for Furcadia to help identify stability issues among their servers before they become noticeable.

What it essentially does is keeping re-connecting to the server and asking it for details about its internal components while notifying of any discrepancies or issues encountered.

Requirements

  • Python3
  • Access to Furcadia characters with the "extended `which" capability

Usage

  • Replace the sample.ini file from the ini/ directory with a working Furcadia character INI file
  • Tweak monitor.py as necessary
  • Start monitor.py as is via Python3 without any arguments
  • Any alerts will be delivered through the STDERR so that this channel can be redirected to other *NIX tools

heimon's Issues

The circumstances of "BUG" alerts are not logged

There should be more details regarding the specific connection that triggered a BUG alert (or any alert whatsoever, in fact):

  • Buffer the regular "log" messages for that one connection
  • Save the result from that one connection
  • Dump all into the alert log for future analysis
  • Take care to avoid dumping irrelevant-to-that-cycle log info

Repeating alerts for a single on-going issue

Example (from daily maintenance that lags the entire system temporarily):
[Sun Apr 10 05:00:08 2016][ALERT!] Heimdall check cycle failed: Timed out during AUTH stage
[Sun Apr 10 05:00:16 2016][ALERT!] Heimdall check cycle failed: Timed out during AUTH stage
[Sun Apr 10 05:00:25 2016][ALERT!] Heimdall check cycle failed: Timed out during AUTH stage
[Sun Apr 10 05:00:33 2016][ALERT!] Heimdall check cycle failed: Timed out during AUTH stage
[Sun Apr 10 05:00:41 2016][ALERT!] Heimdall check cycle failed: Timed out during AUTH stage
[Sun Apr 10 05:00:50 2016][ALERT!] Heimdall check cycle failed: Timed out during AUTH stage
[Sun Apr 10 05:00:58 2016][ALERT!] Heimdall check cycle failed: Timed out during AUTH stage

While the case of missing heimdalls does not repeat itself this way (due to "freshly_missing_threshold" value), all the other alerts from an on-going problem - will. Depending on the reporting mechanism, this can become very annoying and not useful!

There should be an option to avoid frequently-repeating alerts of the same kind on one hand, but on the other hand: long-lasting problems should be brought up again after a while (a la freshly_missing_threshold).
