# Agent HTTP API
|
|
|
|
The `/agent` endpoints are used to interact with the local Consul agent.
|
|
Usually, services and checks are registered with an agent which then takes on
|
|
the burden of keeping that data synchronized with the cluster. For example, the
|
|
agent registers services and checks with the Catalog and performs
|
|
[anti-entropy](/docs/internals/anti-entropy) to recover from outages.
|
|
|
|
In addition to these endpoints, additional endpoints are grouped in the
|
|
navigation for `Checks` and `Services`.
|
|
|
|
## Retrieve host information
|
|
|
|
This endpoint returns information about the host the agent is running on such as
|
|
CPU, memory, and disk.
|
|
|
|
~> Note: this is not a stable API. The structure of the response body may change
|
|
at any time. If you require this data to be in a stable format, please open a
|
|
GitHub issue to discuss your use case.

## List Members
|
|
|
|
This endpoint returns the members the agent sees in the cluster gossip pool. Due
|
|
to the nature of gossip, this is eventually consistent: the results may differ
|
|
by agent. The strongly consistent view of nodes is instead provided by
|
|
`/v1/catalog/nodes`.
|
|
|
|
| Method | Path | Produces |
|
|
| ------ | ---------------- | ------------------ |
|
|
| `GET` | `/agent/members` | `application/json` |
|
|
|
|
The table below shows this endpoint's support for
|
|
[blocking queries](/api/features/blocking),

|
| `NO` | `none` | `none` | `node:read` |
|
|
|
|
### Parameters
|
|
|
|
- `wan` `(bool: false)` - Specifies to list WAN members instead of the LAN
|
|
members (which is the default). This is only eligible for agents running in
|
|
**server mode**. This is specified as part of the URL as a query parameter.
|
|
|
|
- `segment` `(string: "")` <EnterpriseAlert inline /> - Specifies the segment to list members for.
|
|
If left blank, this will query for the default segment when connecting to a server and
|
|
the agent's own segment when connecting to a client (clients can only be part of one
|
|
network segment). When querying a server, setting this to the special string `_all`
|
|
will show members in all segments.
|
|
|
|
### Sample Request

## Read Configuration
|
|
|
|
This endpoint returns the configuration and member information of the local
|
|
agent. The `Config` element contains a subset of the configuration and its
|
|
format will not change in a backwards incompatible way between releases.
|
|
`DebugConfig` contains the full runtime configuration but its format is subject
|
|
to change without notice or deprecation.

|
## Reload Agent
|
|
|
|
This endpoint instructs the agent to reload its configuration. Any errors
|
|
encountered during this process are returned.
|
|
|
|
Not all configuration options are reloadable. See the
|
|
[Reloadable Configuration](/docs/agent/options#reloadable-configuration)
|
|
section on the agent options page for details on which options are supported.

```
|
|
|
|
## Enable Maintenance Mode
|
|
|
|
This endpoint places the agent into "maintenance mode". During maintenance mode,
|
|
the node will be marked as unavailable and will not be present in DNS or API
|
|
queries. This API call is idempotent.
|
|
|
|
Maintenance mode is persistent and will be automatically restored on agent
|
|
restart.

|
### Parameters
|
|
|
|
- `enable` `(bool: <required>)` - Specifies whether to enable or disable
|
|
maintenance mode. This is specified as part of the URL as a query string
|
|
parameter.
|
|
|
|
- `reason` `(string: "")` - Specifies a text string explaining the reason for
|
|
placing the node into maintenance mode. This is simply to aid human operators.
|
|
If no reason is provided, a default value will be used instead. This is
|
|
specified as part of the URL as a query string parameter, and, as such, must
|
|
be URI-encoded.
|
|
|
|
### Sample Request
|
|
|
|
```shell-session
|
|
$ curl \
|
|
--request PUT \
|
|
http://127.0.0.1:8500/v1/agent/maintenance?enable=true&reason=For+API+docs
|
|
```
|
|
|
|
## View Metrics
|
|
|
|
This endpoint will dump the metrics for the most recent finished interval.
|
|
For more information about metrics, see the [telemetry](/docs/agent/telemetry)
|
|
page.
|
|
|
|
In order to enable [Prometheus](https://prometheus.io/) support, you need to use the
|
|
configuration directive
|
|
[`prometheus_retention_time`](/docs/agent/options#telemetry-prometheus_retention_time).
|
|
|
|
Since Consul 1.7.2 this endpoint will also automatically switch output format if
|
|
the request contains an `Accept` header with a compatible MIME type such as
|
|
`application/openmetrics-text`. Prometheus v2.5.0 and newer pass this header in scraping
|
|
queries, and so will get a compatible format by default. Older versions of Prometheus may
|
|
work by default as several previously used MIME types are also detected, but the `?format`
|
|
query parameter may also be used to specify the output format manually if needed.
|
|
simplifying scrape configuration.
|
|
|
|
Note: If using the default format and your metric includes labels that use the same key
|
|
name multiple times (i.e. tag=tag2 and tag=tag1), only the sorted last value (tag=tag2)
|
|
will be visible on this endpoint due to a display issue. The complete label set is correctly
|
|
applied and passed to external metrics providers even though it is not visible through this
|
|
endpoint.

- `Timestamp` is the timestamp of the interval for the displayed metrics. Metrics are
|
|
aggregated on a ten second interval, so this value (along with the displayed metrics)
|
|
will change every ten seconds.
|
|
|
|
- `Gauges` is a list of gauges which store one value that is updated as time goes on,
|
|
such as the amount of memory allocated.
|
|
|
|
- `Points` is a list of point metrics, which each store a series of points under a given name.
|
|
|
|
- `Counters` is a list of counters, which store info about a metric that is incremented
|
|
over time such as the number of requests to an HTTP endpoint.
|
|
|
|
- `Samples` is a list of samples, which store info about the amount of time spent on an
|
|
operation, such as the time taken to serve a request to a specific http endpoint.

## Join Agent
|
|
|
|
This endpoint instructs the agent to attempt to connect to a given address.
|
|
|
|
| Method | Path | Produces |
|
|
| ------ | ---------------------- | ------------------ |
|
|
| `PUT` | `/agent/join/:address` | `application/json` |

| `NO` | `none` | `none` | `agent:write` |
|
|
|
|
### Parameters
|
|
|
|
- `address` `(string: <required>)` - Specifies the address of the other agent to
|
|
join. This is specified as part of the URL.
|
|
|
|
- `wan` `(bool: false)` - Specifies to try and join over the WAN pool. This is
|
|
only optional for agents running in server mode. This is specified as part of
|
|
the URL as a query parameter
|
|
|
|
### Sample Request
|
|
|
|
```shell-session
|
|
$ curl \
|
|
http://127.0.0.1:8500/v1/agent/join/1.2.3.4
|
|
```
|
|
|
|
## Graceful Leave and Shutdown
|
|
|
|
This endpoint triggers a graceful leave and shutdown of the agent. It is used to
|
|
ensure other nodes see the agent as "left" instead of "failed". Nodes that leave
|
|
will not attempt to re-join the cluster on restarting with a snapshot.
|
|
|
|
For nodes in server mode, the node is removed from the Raft peer set in a
|
|
graceful manner. This is critical, as in certain situations a non-graceful leave
|
|
can affect cluster availability.
|
|
|
|
| Method | Path | Produces |

|
```shell-session
|
|
$ curl \
|
|
--request PUT \
|
|
http://127.0.0.1:8500/v1/agent/leave
|
|
```
|
|
|
|
## Force Leave and Shutdown
|
|
|
|
This endpoint instructs the agent to force a node into the `left` state. If a
|
|
node fails unexpectedly, then it will be in a `failed` state. Once in the
|
|
`failed` state, Consul will attempt to reconnect, and the services and checks
|
|
belonging to that node will not be cleaned up. Forcing a node into the `left`
|
|
state allows its old entries to be removed.
|
|
|
|
| Method | Path | Produces |
|
|
| ------ | -------------------------- | ------------------ |
|
|
| `PUT` | `/agent/force-leave/:node` | `application/json` |
|
|
|
|
Additionally, by specifying the `prune` flag, a node can be forcibly removed from
|
|
the list of members entirely.

### Parameters
|
|
|
|
- `node` `(string: <required>)` - Specifies the name of the node to be forced into `left` state. This is specified as part of the URL.
|
|
|
|

|
|
```
|
|
|
|
## Update ACL Tokens
|
|
|
|
This endpoint updates the ACL tokens currently in use by the agent. It can be
|
|
used to introduce ACL tokens to the agent for the first time, or to update
|
|
tokens that were initially loaded from the agent's configuration. Tokens will be persisted
|
|
only if the [`acl.enable_token_persistence`](/docs/agent/options#acl_enable_token_persistence)
|
|
configuration is `true`. When not being persisted, they will need to be reset if the agent
|
|
is restarted.
