• 29 Jan 2018 M.Fuerstenau
  • Version 1.0
  • reformatted code for better readability
  • Changed Getopt::Std into Getopt::Long
  • Changed -h to -H and -c to -C because upper case characters are much more common for plugins. -h ist commonly used for help.
  • All variable defintions at the beginning of the script.
  • Removed unused parts
  • Bugfix: Unknown has now a returncode of 3 and not -1. Fixed.
  • Fixed exit on SNMP error or empty result. A linefeed (\n) doesn't make sense because the error message wouldn't be displayed in Nagios status overview
  • Added whitelist. This will set a filter for monitored pools so that not all pools will be listed. Pools checked will be listed in output as checked pools..
  • Added blacklist to ignore pools. Pools filtered out by blacklist will be listed as ignored pools.
  • Rewritten complete SNMP and outpu part. Some of the stuff used was replaced in SNMP output.
  • Fixed exit on SNMP error or empty result. A linefeed (\n) doesn't make sense because the error message wouldn't be displayed in Nagios status overview
