# SNMP Operations

NetObserv SNMP exposes an HTTP API. This page describes the available endpoints.

#### `POST /api/v1/snmp/apply-definitions`

This endpoint triggers a re-read of all definitions files. Utilizing the `apply-definitions` endpoint allows for zero-downtime reconfiguration of the collector's SNMP definitions. It uses the definition directory paths configured when the collector was started.

**Optional Query Parameters**

**force\_rediscovery**

By default, when object group or object definitions relating to a configured device change, then the device is not rediscovered. When `force_rediscovery` is set to true, and there is a change to the object group or object definitions relating to a device, then the device will automatically be rediscovered.

* Example

```shell
curl --location --request POST 'http://0.0.0.0:8080/api/v1/snmp/apply-definitions?force_rediscovery=true'
```

* Valid Values
  * `true`, `false`
* Default
  * `false`

#### `POST /api/v1/snmp/rediscover-device`

This endpoint triggers a rediscovery of an identified device. Utilizing the `rediscover-device` endpoint allows device rediscovery while the collector is running.

**Required Body Properties**

The body content type must be `application/json` and the following properties are required to identify the device that should be rediscovered:

* `ip`
* `port`

Example:

```shell
curl --location --request POST 'http://0.0.0.0:8080/api/v1/snmp/rediscover-device' \
--header 'Content-Type: application/json' \
--data-raw '{
    "ip": "127.0.0.1",
    "port": 161
}'
```
