Monitoring large memory hosts

[cbeattie]

Does anyone have suggestions for monitoring hosts with large amounts of memory? I mean hundreds of GB here.

We use NSClient++, but mostly the check_nt style checks unless we need something beyond that. The check_nt MEMUSE check works, but takes its warning and critical thresholds as integer percents. If I set the warning and critical to 98 and 99, the notification goes out when there's still several GB free. I would prefer to set the warning more like 99 and critical at 99.5, or to use absolute values like warning at 3GB free and critical at 1,500MB.

You can use NCPA and use the "G" with the "-u" flag in your command, for example:

Code: Select all

./check_ncpa.py -H 192.168.x.x -t "mytoken" -P 5693 -M 'disk/logical/C:|/used' -u G -w 350 -c 400
WARNING: Used was 360.882Gb|'used_0'=360.882Gb;350;400

./check_ncpa.py -H 192.168.x.x -t "mytoken" -P 5693 -M 'disk/logical/C:|/used' -u G -w 400 -c 420
OK: Used was 360.882Gb|'used_0'=360.882Gb;400;420

Thank you! I will check that out.
