Zabbix 1.8.3 on Solaris 10 x86
I have a firewall which I monitor in zabbix over SNMP for which I try to monitor the bandwidht on a certain interface.
The data returned via SNMP is a Counter64
# snmpwalk -v 2c -c BLAH fw IF-MIB::ifHCInOctets.3
IF-MIB::ifHCInOctets.3 = Counter64: 263157545561
This is my item definition in zabbix:
---
SNMP OID: IF-MIB::ifHCInOctets.3
Key: ifHCInOctets.3
Type of information: numeric (unsigned)
Data type: Decimal
Units: bps
Update interval (in sec): 300
Use custom multiplier: 8
Store value: Delta (speed per second)
---
That all seems to work well until we noted a spike which exceeded the physical capacity of that port so we set out to investigate.
The first thing I did was to add another item which just stores the value as is
---
SNMP OID: .1.3.6.1.2.1.31.1.1.1.6.3
Key: .1.3.6.1.2.1.31.1.1.1.6.3
Type of information: numeric (unsigned)
Data type: Decimal
Update interval (in sec): 300
Store value: As Is
---
The strange thing is if I compare the values zabbix stores and the ones I get back from a SNMP walk they differ for any gives time by a factor 2
Zabbix:
Description Last check Last value
ifHCInOctets.3.values 15 Jun 2011 17:38:34 525168136921
SNMP
Wed Jun 15 17:38:34 CEST 2011
IF-MIB::ifHCInOctets.3 = Counter64: 263175131805
Can anyone point out what I am overseeing please?
