node-red-node-snmp ================== A pair of Node-RED nodes that fetch either individual oids, or a table oid from a SNMP enabled host. Install ------- Run the following command in your Node-RED user directory - typically `~/.node-red` npm install node-red-node-snmp Usage ----- ### snmp SNMP oids fetcher. Can fetch a single or comma separated list of oids. Triggered by any input. `msg.host` may contain the host. `msg.community` may contain the community. `msg.oid` may contain a comma separated list of oids to search for. (no spaces) The host configured in the edit config will override `msg.host`. Leave blank if you want to use `msg.host` to provide input. The community configured in the edit config will override `msg.community`. Leave blank if you want to use `msg.community` to provide input. The oids configured in the edit config will override `msg.oid`. Leave blank if you want to use `msg.oid` to provide input. Outputs `msg.payload` containing a table of objects, and the requested `msg.oid`. Values depends on the oids being requested. ### snmp-set SNMP sets the value of one or more OIDs. `msg.host` may contain the host. `msg.community` may contain the community. `msg.varbinds` may contain an array of varbind JSON objects e.g.: ``` msg.varbinds = [ { "oid": "1.3.6.1.2.1.1.5.0", "type": "OctetString", "value": "host1" }, { "oid": "1.3.6.1.2.1.1.6.0", "type": "OctetString", "value": "somewhere" } ]; ``` Types can be: * `Boolean` * `Integer` * `OctetString` * `Null` * `OID` * `IpAddress` * `Counter` * `Gauge` * `TimeTicks` * `Opaque` * `Integer32` * `Counter32` * `Gauge32` * `Unsigned32` * `Counter64` * `NoSuchObject` * `NoSuchInstance` * `EndOfMibView` The host configured in the edit config will override `msg.host`. Leave blank if you want to use `msg.host` to provide input. The community configured in the edit config will override `msg.community`. Leave blank if you want to use `msg.community` to provide input. The varbinds configured in the edit config will override `msg.varbinds`. Leave blank if you want to use `msg.varbinds` to provide input. ### snmp-table Simple SNMP table oid fetcher. Triggered by any input. `msg.host` may contain the host. `msg.community` may contain the community. `msg.oid` may contain the oid of a single table to search for. The host configured in the edit config will override `msg.host`. Leave blank if you want to use `msg.host` to provide input. The community configured in the edit config will override `msg.community`. Leave blank if you want to use `msg.community` to provide input. The oid configured in the edit config will override `msg.oid`. Leave blank if you want to use `msg.oid` to provide input. Outputs `msg.payload` containing the table of objects, and the requested `msg.oid`. Values depends on the oids being requested. ### snmp-subtree Simple SNMP oid subtree fetcher. Triggered by any input. `msg.host` may contain the host. `msg.community` may contain the community. `msg.oid` may contain the oid of a single table to search for. The host configured in the edit config will override `msg.host`. Leave blank if you want to use `msg.host` to provide input. The community configured in the edit config will override `msg.community`. Leave blank if you want to use `msg.community` to provide input. The oid configured in the edit config will override `msg.oid`. Leave blank if you want to use `msg.oid` to provide input. Outputs `msg.payload` containing the table of objects, and the requested `msg.oid`. Values depends on the oids being requested. ### snmp-walker Simple SNMP oid walker fetcher. Triggered by any input. `msg.host` may contain the host. `msg.community` may contain the community. `msg.oid` may contain the oid of a single table to search for. The host configured in the edit config will override `msg.host`. Leave blank if you want to use `msg.host` to provide input. The community configured in the edit config will override `msg.community`. Leave blank if you want to use `msg.community` to provide input. The oid configured in the edit config will override `msg.oid`. Leave blank if you want to use `msg.oid` to provide input. Outputs `msg.payload` containing the table of objects, and the requested `msg.oid`. Values depends on the oids being requested.
