InfluxDB Configuration Example with CollectD

April 14, 2015 No Comments collectd, influxdb

Note that this is just an InfluxDB configuration example. Change it to suit your own needs.

Run InfluxDB with its configuration file:

1
influxd -config="config.toml"

With this configuration InfluxDB will:

  • Not require any login/password to read and write to the database
  • Listen to commands on port 8066
  • Listen to CollectD metrics on port 25826
  • Save CollectD metrics in “collectd_db”  (InfluxDB database must exist)
  • Run the admin web interface on port 8083
  • Record on disk in the /var/opt/influxdb/ directory
