Dear Community,
i’m quite confuse about the description of snmp ucd_mem,
“Note that the check counts buffered and cached memory as free memory, as one should for Linux systems.”
Ok, that’s fine to me. But … what i observe actually, is a bit different (opposite)
plugin say : Service Metrics RAM used: 3.61 GB
Ok, let’s have a look on host ‘free’ command output:
total used free shared buff/cache available
Mem: 4047384 1638900 267912 51844 2140572 2119060
Swap: 1046524 384 1046140
or more readable ‘free -m’ ouput is
total used free shared buff/cache available
Mem: 3952 1601 260 50 2091 2068
Swap: 1021 0 1021
so obviously, buff/cache IS included on computation of RAM USED, but according to check_mk documentation, it should not because consider as free mem.
Is plugin bogus or documentation outdated ? ( or did i miss something)
I’m using check_mk raw edition 1.6.0p13.
