The SNMP service monitors the performance and health of the SNMP agent on a device. SNMP is a widely used network management protocol that is present in a majority of network infrastructures (routers, switches, firewalls, and so on) as well as in different types of computing platforms.
|Instances on a Device||1|
|Device Class||Server - Generic, Workstation - Generic, Other, Printer, Scanner/Camera, Switch/Router, and Workstation - Windows|
|Monitored By||Windows probe|
|Scan Interval||15 minutes|
The table SNMPV2-MIB describes the SNMP objects that are queried by the probe.
|Object Descriptors||Numerical OID|
SolarWinds N-central services use Reverse Polish Notation (RPN) for all calculation formulae.
|Number of SNMP messages with version error||^snmpInBadVersions||The number of SNMP queries received by the SNMP agent on the target device that were for an unsupported version of SNMP.|
|Number of wrong community string messages||^snmpInBadCommunityNames||The number of SNMP queries received by the SNMP agent on the device that used an incorrect SNMP community string.|
|Number of messages with an invalid user||^snmpInBadCommunityUses||The number of SNMP messages received by the SNMP agent on the device which requested an SNMP operation which was not allowed by the SNMP community string in the message.|
|Number of SNMP messages unparsed||^snmpInASNParseErrs||The number of SNMP messages received by the SNMP agent on the device with syntax errors.|
|Number of messages with invalid status bits||^snmpInTooBig+^snmpNoSuchName+^snmpBadValue+^snmpGenError+^snmpOutTooBig||The number of SNMP messages received by or transmitted from the SNMP agent on the target device, which indicates an error status.|
