Container metrics collection -- Telegraf (on windows) throws error, when configured for docker

mamudragon · October 2, 2017, 3:16pm

Telegraf, Chronograf,Influxdb - all running locally on windows 10 Pro-64-bit laptop.

As am a new user, I cannot attach the telegraf.conf here. Never seen a forum so restrictive like this.

Telegraf throws runtime error, when inputs.docker section is configured.

Error below :

## Bug report Trying to collect docker container metrics using Grafana-Influxdb…-Telegraf on Windows 10, but Telegraf throws error ### Relevant telegraf.conf: DOCKER INPUT PLUGIN telegraf.conf - ``` [[inputs.docker]] # ## Docker Endpoint # ## To use TCP, set endpoint = "tcp://[ip]:[port]" # ## To use environment variables (ie, docker-machine), set endpoint = "ENV" # endpoint = "unix:///var/run/docker.sock" endpoint = "localhost:2375" # # ## Only collect metrics for these containers, collect all if empty container_names = [] # # ## Containers to include and exclude. Globs accepted. # ## Note that an empty array for both will include all containers container_name_include = [] container_name_exclude = [] # # ## Timeout for docker list, info, and stats commands timeout = "5s" ``` ### System info: Windows-10-Pro-64-bit docker CE 17.x Using telegraf Repo-official (v1.3) InfluxDB - official Repo ### Steps to reproduce: 1. Uncommented inputs.docker to timeout, as mentioned above 2. copied telegraf.conf from host to container. 3. Error 1 : influxdb on localhost:8086 not recognized, by telegraf container Log : Database creation failed: Post http://localhost:8086/query?q=CREATE+DATABASE+%22telegraf%22: dial tcp 127.0.0.1:8086: getsockopt: connection refused 4.

A readymade file in windows for enabling all container metrics should be supplied. different Opening a feature request kicks off a discussion. ### Proposal: ### Current behavior: ### Desired behavior: ### Use case: [Why is this important (helps with prioritizing requests)] [telegraf.conf.txt](https://github.com/influxdata/telegraf/files/1345359/telegraf.conf.txt)
