-Using this collector, Netdata can collect data from any SNMP device.
+# SNMP device monitoring with Netdata
-This collector supports:
+Collects data from any SNMP device and uses the [net-snmp](https://github.com/markabrahams/node-net-snmp) module.
+It supports:
+
+- all SNMP versions: SNMPv1, SNMPv2c and SNMPv3
- any number of SNMP devices
- each SNMP device can be used to collect data for any number of charts
- each chart may have any number of dimensions
- each SNMP device may have a different update frequency
- each SNMP device will accept one or more batches to report values (you can set `max_request_size` per SNMP server, to control the size of batches).
+## Requirements
+
+- `nodejs` minimum required version 4
+
## Configuration
You will need to create the file `/etc/netdata/node.d/snmp.conf` with data like the following.

The `options` given for each server, are:
-- `timeout`, the time to wait for the SNMP device to respond. The default is 5000 ms.
-- `version`, the SNMP version to use. `0` is Version 1, `1` is Version 2c. The default is Version 1 (`0`).
-- `transport`, the default is `udp4`.
-- `port`, the port of the SNMP device to connect to. The default is `161`.
-- `retries`, the number of attempts to make to fetch the data. The default is `1`.
+- `port` - UDP port to send requests too. Defaults to `161`.
+- `retries` - number of times to re-send a request. Defaults to `1`.
+- `sourceAddress` - IP address from which SNMP requests should originate, there is no default for this option, the operating system will select an appropriate source address when the SNMP request is sent.
+- `sourcePort` - UDP port from which SNMP requests should originate, defaults to an ephemeral port selected by the operation system.
+- `timeout` - number of milliseconds to wait for a response before re-trying or failing. Defaults to `5000`.
+- `transport` - specify the transport to use, can be either `udp4` or `udp6`. Defaults to `udp4`.
+- `version` - either `0` (v1) or `1` (v2) or `3` (v3). Defaults to `0`.
+- `idBitsSize` - either `16` or `32`. Defaults to `32`. Used to reduce the size of the generated id for compatibility with some older devices.
+
+## SNMPv3
+
+To use SNMPv3:
+
+- set `version` to 3
+- use `user` instead of `community`
+
+User syntax:
+
+```json
+{
+ "user": {
+ "name": "userName",
+ "level": 3,
+ "authProtocol": "3",
+ "authKey": "authKey",
+ "privProtocol": "2",
+ "privKey": "privKey"
+ }
+}
+```
+
+Security levels:
+
+- 1 is `noAuthNoPriv`
+- 2 is `authNoPriv`
+- 3 is `authPriv`
+
+Authentication protocols:
+
+- "1" is `none`
+- "2" is `md5`
+- "3" is `sha`
+
+Privacy protocols:

+- "1" is `none`
+- "2" is `des`
