@HINTS

{% hint 'warning' %}
9+
This endpoint should no longer be used. It is deprecated from version 3.8.0 on.
10+
Use `/_admin/metrics/v2` instead, which provides the data exposed by this API
11+
and a lot more.

@RESTQUERYPARAM{serverId,string,optional}
10+
Returns metrics of the specified server. If no serverId is given, the asked
11+
server will reply. This parameter is only meaningful on Coordinators.
12+
13+
@RESTDESCRIPTION
14+
Returns the instance's current metrics in Prometheus format. The
15+
returned document collects all instance metrics, which are measured
16+
at any given time and exposes them for collection by Prometheus.
17+
18+
The document contains different metrics and metrics groups dependent
19+
on the role of the queried instance. All exported metrics are
20+
published with the prefix `arangodb_` or `rocksdb_` to distinguish them from
21+
other collected data.
22+
23+
The API then needs to be added to the Prometheus configuration file
24+
for collection.

32+
The metrics API may be disabled using `--server.export-metrics-api false`
33+
setting in the server. In this case, the result of the call indicates the API
34+
to be not found.
