API Endpoints & Ports

This is archived documentation for InfluxData product versions that are no longer maintained. For newer documentation, see the latest InfluxData documentation.


All current API Endpoints are listed below.


The ping endpoint accepts both GET and HEAD HTTP requests. The response body is empty. The version of the InfluxDB server you issued the request to can be extracted through the X-Influxdb-Version field of the header. For example this is the response from a server running 0.11.0 of InfluxDB:

$ curl -sl -I localhost:8086/ping

HTTP/1.1 204 No Content
Request-Id: 7d641f0b-e23b-11e5-8005-000000000000
X-Influxdb-Version: 0.11.0
Date: Fri, 04 Mar 2016 19:01:23 GMT

The /ping endpoint can also accept an optional query param, wait_for_leader=Ns where N is the number of seconds to wait before returning a response. This will check with the leader of the cluster to ensure that the leader is available and ready. One second is a good default, but for highly distributed clusters, or clusters under significant load, it may lead to false negatives. Increasing the timeout gives the raft leader longer to respond. The request will return 204 if successful and 503 in the case of a timeout.

$ curl -sl -I localhost:8086/ping?wait_for_leader=1s

HTTP/1.1 204 No Content
Request-Id: b280e5eb-e23b-11e5-8019-000000000000
X-Influxdb-Version: 0.11.0
Date: Fri, 04 Mar 2016 19:02:53 GMT
