BIG-IP SNMP sensor

The BIG-IP SNMP sensor discovers F5 BIG-IP load balancers.

The SnmpMib2Sensor invokes the BigIPSnmpSensor if the latter one matches one of the following OIDs:

  • .1.3.6.1.4.1.3375
  • .1.3.6.1.4.1.2021.250.255

The BigIPSnmpSensor collects information about virtual IPs and real server groups.

Object identifiers (OIDs) that are used

The sensor follows the standards that are documented in RFC 1212 to get the Real Server Database (RSD) and the Virtual Server Database (VSD) table entries.

The sensor uses the following OIDs:
