dobry..
rozhodol som sa ze si zacnem grafovat cpu vyuzitie a tak, ale mam problem.
z tohoto webu ( http://www.enterastream.com/whitepapers/mrtg/mrtg-manual-cap9.html ) som si dal konfiguraciu
Target[10.0.0.254-cpu]:.1.3.6.1.4.1.311.1.1.3.1.1.33.9.0&.1.3.6.1.4.1.311.1.1.3.1.1.33.9.0:public@10.0.0.254
AbsMax[10.0.0.254-cpu]: 100
MaxBytes[10.0.0.254-cpu]: 100
Title[10.0.0.254-cpu]: CPU Utilization (average)
PageTop[10.0.0.254-cpu]: CPU Utilization
Options[10.0.0.254-cpu]: gauge,growright,nopercent, noo
YLegend[10.0.0.254-cpu]: CPU Utilization
ShortLegend[10.0.0.254-cpu]: %
LegendI[10.0.0.254-cpu]: CPU Utilization (percentage)
vsetko by islo len ked idem spustit MRTG tak vyhodi toto:
root@buri-laptop:/net# env LANG=C /usr/bin/mrtg /home/buri/mrtg.conf
SNMP Error:

dalej ako som skusal, tak hociaky snmpwalk prikaz ak zadam, hned mi vrati toto:
root@buri-laptop:/etc/snmp# snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.2021.9
End of MIB
viete niekto poradit?
snmp+mrtg - cpu graph?
Dal som si debian, a druhy HDD s naj vecami sa mi zmazal xD

preco to robis cez snmp? ak tie data ziskavas len z localhost-u tak je zbytocne. mrtg dokaze spustit hocijaky skript co si napises a jeho vystup pouzije ako data pre graf.
napr.:
# more /etc/mrtg/cpu.confTarget[cpu_percent]: ` sar -P ALL 1 1|grep Average|grep all|awk {'print $3'}'`
....
Target[cpu0.0]: `sar -P 0 1 1|grep Average|awk {'print $3'}`
AbsMax[cpu0.0]: 100
MaxBytes[cpu0.0]: 100
Title[cpu0.0]: CPU Utilization (average)
PageTop[cpu0.0]: CPU Utilization
Options[cpu0.0]: gauge,growright,nopercent, noo
YLegend[cpu0.0]: CPU Utilization
ShortLegend[cpu0.0]: %
LegendI[cpu0.0]: CPU Utilization (percentage)
a pise:
root@buri-laptop:/home/buri# env LANG=C /usr/bin/mrtg /home/buri/mrtg.conf
2010-07-05 12:46:18: WARNING: Problem with External get 'sar -P 0 1 1|grep Average|awk {'print $3'}':

2010-07-05 12:46:22: ERROR: Target[cpu0.0][_OUT_] ' $target->[3]{$mode} ' did not eval into defined data
root@buri-laptop:/home/buri#
daj si to do googla. Zatial narychlo skus:
sar -P 0 1 1|grep Average|awk {'print $3'} && echo 0Mne taketo nieco normalne funguje, ale musim mat nakonfigurovanu a beziacu sluzbu SNMP ktora nesmie mat blokovanu komunikaciu medzi strojom na ktorom bezi SNMP a kolektovaciou masinou (napriklad cez firewall).
Pre MIBs som sa s tym moc nehral, jednoducho som vyuzil UCB definiciu a u mna to vyzera takto:
S preklepmi som sa nekaslal, je to lokalne na mojom desktope. A mam jednoprocesorovu masinu, preto max 100%.
