SNMP traps for system alerts
Each IT Analytics trap contains 2 standard object identifiers and 13 IT Analytics-specific object identifiers. An object identifier (or OID) is a numeric string that is used to uniquely identify an object.
The following table shows the contents of a trap that is sent from IT Analytics. A total of 15 bindings (or 15 name-value pairs) are present in each trap that is sent from IT Analytics. Each binding associates a particular Management Information Base (MIB) object instance with its current value.
IT Analytics trap binding shows the name-value pairs that the traps pass to the SNMP manager if SNMP payload format is selected as Enhanced.

The first two OIDs listed in the table are standard SNMP OIDs. The other OIDs starting from 1.3.6.1.4.1.15622.3.12.10.1.1 to 1.3.6.1.4.1.15622.3.12.10.1.12 are IT Analytics OIDs. As per SNMPv2c trap definition, the two standard SNMP OIDs must be present as part of every trap.
All the 12 IT Analytics OIDs are defined in the IT Analytics MIB files. However, the two standard OIDs are not defined in the IT Analytics MIB files.
