Collect Etcd metrics to:
The Etcd check is included in the Datadog Agent package, so you don’t need to install anything else on your Etcd instance(s).
To configure this check for an Agent running on a host:
etcd.d/conf.yaml
file, in the conf.d/
folder at the root of your Agent’s configuration directory to start collecting your Etcd performance data. See the sample etcd.d/conf.yaml for all available configuration options.Collecting logs is disabled by default in the Datadog Agent, enable it in your datadog.yaml
file:
logs_enabled: true
Uncomment and edit this configuration block at the bottom of your etcd.d/conf.yaml
:
logs:
- type: file
path: "<LOG_FILE_PATH>"
source: etcd
service: "<SERVICE_NAME>"
Change the path
and service
parameter values based on your environment. See the sample etcd.d/conf.yaml for all available configuration options.
For containerized environments, see the Autodiscovery Integration Templates for guidance on applying the parameters below.
Parameter | Value |
---|---|
<INTEGRATION_NAME> | etcd |
<INIT_CONFIG> | blank or {} |
<INSTANCE_CONFIG> | {"prometheus_url": "http://%%host%%:2379/metrics"} |
Collecting logs is disabled by default in the Datadog Agent. To enable it, see Kubernetes log collection.
Parameter | Value |
---|---|
<LOG_CONFIG> | {"source": "etcd", "service": "<SERVICE_NAME>"} |
Run the Agent’s status
subcommand and look for etcd
under the Checks section.

Etcd metrics are tagged with etcd_state:leader
or etcd_state:follower
, depending on the node status, so you can easily aggregate metrics by status.
The Etcd check does not include any events.
etcd.can_connect
Returns CRITICAL
if unable to get metrics from etcd (timeout or non-200 HTTP code). This service check is only available on the legacy version of the etcd check.
Statuses: ok, critical
etcd.healthy
Returns CRITICAL
when a member is unhealthy. This service check is only available on the legacy version of the etcd check.
Statuses: ok, critical, unknown
etcd.prometheus.health
Returns CRITICAL
if the check cannot access a metrics endpoint. Otherwise, returns OK
. This service check is only available when use_preview
is enabled.
Statuses: ok, critical
