Install Telegraf and configure for InfluxDB
Video Lecture
Description
Now to install the Telegraf agent and configure the output plugin to save data into the InfluxDB.
sudo apt install telegraf -y
Start Telegraf and ensure it starts in case of reboot.
sudo systemctl start telegraf sudo systemctl status telegraf
Ensure it auto starts in case of system, reboot
sudo systemctl enable telegraf
Look at the telegraf configuration file
sudo nano /etc/telegraf/telegraf.conf
Leave all the defaults, but ensure your outputs.influxdb section has the following.
# Output Plugin InfluxDB [[outputs.influxdb]] database = "telegraf" urls = [ "http://127.0.0.1:8086" ] username = "telegraf" password = "password"
Check that the Telegraf configuration is valid.
sudo telegraf -test -config /etc/telegraf/telegraf.conf
Now, create a user that the Telegraf process can use to push data to InfluxDB
influx
> create user telegraf with password 'password' > show users > grant ALL on telegraf to telegraf > show GRANTS for telegraf > quit
Restart Telegraf, and check its status.
sudo service telegraf restart sudo service telegraf status
Examine the Influxdb changes
influx
use telegraf show measurements quit
Go back into Grafana and explore the new data.
