From 9ceabfc974d4d9bfd0731bbedfa12a035a662466 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Minor feature updates to check_snmp_process.pl
The following features are included:
1. Added new `-T` option, to report/check against the total RAM of all matched processes, rather than the highest value
2. Warn/Crit values are now optional for `-m` and `-u` options, allowing for capture of these in perfdata without requiring thresholds
3. Perfdata is now always written if `-F` is supplied, even if there were no matched process (i.e. `num_process=0 memory_usage=0 cpu_usage=0`).
