Connectors of the snmp typeUsed for getting data over Simple Network Management Protocol (SNMP) when working with Windows and Linux agents. To process events received over SNMP, you must use the json normalizer. Supported SNMP versions:
snmpV1
snmpV2
snmpV3
Only one snmp connector created in the agent settings can be used in an agent. If you need to use multiple snmp connectors, you must create one or all snmp connectors as a separate resource and select it in the connection settings.
Available settings for a connector of the snmp type are described in the following tables.

Rules for naming the received data, according to which OIDs (object identifiers) are converted to the keys with which the normalizer can interact. Available settings:
Parameter name is the name for the data type, for example, Host name or Host uptime.
Required setting.
OID is a unique identifier that determines where to look for the required data at the event source, for example, 1.3.6.1.2.1.1.5.
Required setting.
Key is a unique identifier returned in response to a request to the device with the value of the requested parameter, for example, sysName. You can reference the key when normalizing data.
Required setting.
If the MAC address check box is selected, KUMA correctly decodes data where the OID contains information about the MAC address in OctetString format. After decoding, the MAC address is converted to a String value of the XX:XX:XX:XX:XX:XX format.
You can do the following with rules:
