API Endpoints & Ports

Warning! This page documents an old version of InfluxDB, which is no longer actively developed. InfluxDB v1.3 is the most recent stable version of InfluxDB.

Endpoints

All current API Endpoints are listed below.

/ping

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 0.10.3 of InfluxDB:

$ curl -sl -I localhost:8086/ping

HTTP/1.1 204 No Content
Request-Id: 7d641f0b-e23b-11e5-8005-000000000000
X-Influxdb-Version: 0.10.3
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: 0.10.3
Date: Fri, 04 Mar 2016 19:02:53 GMT

/query

For more information on the /query endpoint see the Querying Data section of our docs.

/write

For more information on the /write endpoint see the Writing Data section of our docs.

Ports

HTTP API PORT

By default the InfluxDB HTTP API listens on port 8086. The /ping, /write, and /query endpoints are all part of the HTTP API.

Internal Communication port

By default, the communication between clustered instances of InfluxDB occurs over ports 8088 and 8091.

Admin interface port

The admin interface for InfluxDB runs on port 8083 and exposes web UI for the server.

Secondary Ports

InfluxDB also supports communication through UDP, Graphite, Collectd, and OpenTSDB. By default InfluxDB makes port 2003 available for Graphite. No default ports are assigned for UDP, Collectd, or OpenTSDB.
