SNMP e utilizzo cpu

[nik600]

ciao

sapreste spiegarmi come posso recuperare tramite snmpget o snmpwalk l'utilizzo di cpu di un determinato host in percentuale?

grazie

ciao

se può interessarvi dalle faq di snmp dovrei aver trovato il modo:

This one of the "raw counters" mentioned in the previous entry.
You need to take two readings of this object and look at the
difference between them. That difference divided by the total
number of 'ticks' between the two readings (where one tick is
probably 0.01 seconds) will give you the percentage utilization
over that period.

ad esempio

nik600@criminal:/home/programmi/prove/snmp$ date && snmpwalk -v 1 -c public localhost ssCpuRawIdle
Thu Apr 13 18:00:29 CEST 2006
UCD-SNMP-MIB::ssCpuRawIdle.0 = Counter32: 1959896

nik600@criminal:/home/programmi/prove/snmp$ date && snmpwalk -v 1 -c public localhost ssCpuRawIdle
Thu Apr 13 18:00:38 CEST 2006
UCD-SNMP-MIB::ssCpuRawIdle.0 = Counter32: 1960729

differenza:9 secondi = 900 ticks

(1960729 - 1959896) = 833 / 900 = 0.92 idle = 8 % di CPU
