Permission denied on restarting telegraf

Telegraf

Running (Telegraf 1.1.0) on a RHEL 7.0 machine, I am getting a permission denied error when restarting telegraf:

â telegraf.service - The plugin-driven server agent for reporting metrics into InfluxDB

I only changed logging option in configuration file to quiet = true.
Seems like the file /etc/telegraf/telegraf_error.log cannot be created because of permission issue.

Note that I am running the service as root, and telegraf user is already added to the group telegraf.

Any ideas?

thanks

What is your logfile set to under the agent section? It should normally be: logfile = "".

@daniel it’s the same file mentioned in the error: logfile = "/etc/telegraf/telegraf_error.log"

Change it to logfile = "", since you are using systemd you will want it to handle logging.
