It was also strange to find out about dead disk from LEDs on the front panel of the server and not from the logs. cpqarray driver is giving me hard times with logs and console every time there is a problem with the device.<\/p>\n<p>Working on netsaint2mrtg taught me to put &#8220;1;&#8221; at the end of the files that I will &#8220;require&#8221; later on. Easy thing to put it, hard to remember though, but perl errors are very descriptive. :) Both the config converter and plugin wrapper are ready now and are running in test environment with about 30 servers and 400 services monitoring.
