# 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
}'
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.elastiflow.com/snmpcoll/api-reference-overview/snmp.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
