proc.mem confusion
I read through tons of forum entries and I slowly get it, but I am still confused how proc.mem works. It seems to work and not work ...
For example for testing I try to monitor my firefox and various kde applications on my box.
Firefox works as I want, I have two of them with different startup parameters.
# zabbix_agent -t 'proc.mem[firefox-bin]'
proc.mem[firefox-bin] [u|2031833088]
# zabbix_agent -t 'proc.mem[firefox-bin,,,default]'
proc.mem[firefox-bin,,,default] [u|1204211712]
# zabbix_agent -t 'proc.mem[firefox-bin,,,Development]'
proc.mem[firefox-bin,,,Development] [u|828407808]
bing, but when I try to do the same thing with kde, it fails.
I want to monitor all kde apps, so everything with "kdeinit" and then all konsole, all kate, etc.
Most kde apps look in ps like this
kate [kdeinit]
kwrite [kdeinit]
konsole [kdeinit]
but some look like this
konsole [kdeinit] -session .....
So I thought I ill just write:
# zabbix_agent -t 'proc.mem[konsole]'
proc.mem[konsole] [u|0]
but that doesn't return anything. so I tried
# zabbix_agent -t 'proc.mem[konsole [kdeinit]]'
proc.mem[konsole [kdeinit]] [u|379822080]
and that returns all the konsole EXCEPT the ones that have -session string.
This really confused me. Why is that? With the firefox, that has similar parameters, it correctly gets it, with kde it doesn't work. Is then "[kdeinit]" consufing it.
But one more thing confused me too. When I do this:
# zabbix_agent -t 'proc.mem[kate [kdeinit]]'
proc.mem[kate [kdeinit]] [u|501219328]
and I do this:
# zabbix_agent -t 'proc.mem[,,,kate]'
proc.mem[,,,kate] [u|505008128]
I get different numbers because the second one includes a grep:
# ps waux|grep kate
gullevek 1986 0.0 0.8 145032 30048 ? S Nov05 0:28 kate [kdeinit]
gullevek 14888 0.1 1.3 344440 49748 ? S Oct10 89:34 kate [kdeinit]
root 31400 0.0 0.0 4748 744 pts/44 S+ 10:31 0:00 grep kate
If I sum up the memory of all processes I get the second sum.
Somehow I think I still don't get proc.mem
Anyone can help me?
