Statisticile pentru "eth0" functioneaza, insa nu si cele care fac
referire la CPU si memorie
Am incercat sa folosesc snmpwalk si pare OK:
s9:~ # snmpwalk -v1 -c public localhost ssCpuRawUser
UCD-SNMP-MIB::ssCpuRawUser.0 = Counter32: 2625580
s9:~ # snmpwalk -v1 -c public localhost memAvailReal.0
UCD-SNMP-MIB::memAvailReal.0 = INTEGER: 52240
Din cate am mai citit pe cateva forumuri, pare sa fie o problema de
trecere a snmp de la v1 la v2, insa nu am reusit sa ma prind cum pot
totusi sa prelevez rezultate despre ceea ce ma intereseaza si sa le
"pictez" pe un grafic.
Pe versiuni anterioare de SuSE, problema nu apare.
Multumesc!
