# SNMP Receiver
|
|
|
|
```json
|
|
"<name>": {
|
|
"type": "snmp",
|
|
"read_interval": "30s",
|
|
"targets" : [{
|
|
"hostname" : "host1.example.com",
|
|
"port" : 161,
|
|
"community": "public",
|
|
"timeout" : 1,
|
|
}],
|
|
"metrics" : [
|
|
{
|
|
"name": "sensor1",
|
|
"value": "1.3.6.1.2.1.1.4.0",
|
|
"unit": "1.3.6.1.2.1.1.7.0",
|
|
},
|
|
{
|
|
"name": "1.3.6.1.2.1.1.2.0",
|
|
"value": "1.3.6.1.2.1.1.4.0",
|
|
"unit": "mb/s",
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
The `snmp` receiver uses [gosnmp](https://github.com/gosnmp/gosnmp) to read metrics from network-attached devices.
|
|
|
|
The configuration of SNMP is quite extensive due to it's flexibility.
|
|
|
|
## Configuration
|
|
|
|
- `type` has to be `snmp`
|
|
- `read_interval` as duration like '1s' or '20s' (default '30s')
|
|
|
|
For the receiver, the configuration is split in two parts:
|
|
### Target configuration
|
|
|
|
Each network-attached device that should be queried. A target consits of
|
|
- `hostname`
|
|
- `port` (default 161)
|
|
- `community` (default `public`)
|
|
- `timeout` as duration like '1s' or '20s' (default '1s')
|
|
- `version` SNMP version `X` (`X` in `1`, `2c`, `3`) (default `2c`)
|
|
- `type` to specify `type` tag for the target (default `node`)
|
|
- `type-id` to specify `type-id` tag for the target
|
|
- `stype` to specify `stype` tag (sub type) for the target
|
|
- `stype-id` to specify `stype-id` tag for the target
|
|
|
|
### Metric configuration
|
|
- `name` can be an OID or a user-given string
|
|
- `value` has to be an OID
|
|
- `unit` can be empty, an OID or a user-given string
|
|
|
|
If a OID is used for `name` or `unit`, the receiver will use the returned values to create the output metric. If there are any issues with the returned values, it uses the `OID`. |
