Module: F5-3DNS-MIB
OID (symbolic): F5-3DNS-MIB::hostCPU
OID (numeric): 1.3.6.1.4.1.3375.1.2.1.1.4.1.1.14
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: CPU utilization. All CPU utilization is expressed a percentage rounded up to the nearest integer. CPU utilization is computed differently for each SNMP agent. CPU usage is computed for the UCD mib as the load average in the last 5 minutes divided by a configured maximum saturated load average. CPU usage is computed for the Solstice mib as the number of time ticks spent in user and system execution divided by the total number of elapsed time tics. If this statistic is not available it will have a value of -1.
What is hostCPU?
The host's current CPU utilization as a percentage (rounded up), computed differently depending on the SNMP agent type - e.g. 5-minute load average versus a configured saturation threshold for UCD-SNMP hosts, or user+system ticks over elapsed ticks for Solstice hosts; -1 means unavailable. The 'cpu' load-balancing mode reads this to avoid sending traffic to an already CPU-saturated host.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3375.1.2.1.1.4.1.1.14 snmpwalk -v2c -c public <target> F5-3DNS-MIB::hostCPU
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3375.1.2.1.1.4.1.1.14.1 snmpget -v2c -c public <target> F5-3DNS-MIB::hostCPU.1
