proc.mem: is it really useful to monitor ?

[BDiE8VNy]

Beginning with ZBXNEXT-1550 an Zabbix-Agent can be extended with missing items (almost) as easy as it is currently possible via UserParameters but with the same efficiency of native build-in support.

+1 for proc.mem[VIRT/RES/SHR]

imho it's an essential for a proper process monitoring or at least rss is more useful then virt.

proc.stats

Here's what I did

UserParameter=proc.stats[*],/usr/local/bin/proc.stats.sh \$1 \$2

I won't bore you too much with proc.stats.sh, but it essentially does this...

/bin/ps --noheader -C $1 -o $2 | awk 'BEGIN {total=0} {total+=$0} END { print total}'

And I call it like this...
proc.stats[nfsd,vsize]
proc.stats[nfsd,rss]
the second parameter can be these and total works
%cpu|%mem|rss|vsize|lstart|majflt|minflt

I wrote some summarization stuff for things like
uptime (up time in seconds)
time (cpu seconds)
nproc (num processes with that command)
nfiles (num files open)

zabbix_get -s 192.168.1.99 -k proc.stats[nfsd,uptime]

Hi guys,

Is there any progress with adding RSS monitoring feature for proc.mem item? It would be very useful to have this possibility.

Regards!

Has anyone filed a ZBX item for this so we can vote as I agree VSS is useless and we've been looking at adding an agent module for this, though to extend it to look at sum, max, avg of RSS for a group of processes, too - we need to sum(rss) for Apache, for example, and do math on the avg(rss).
