Install Telegraf using Ansible

I have an InfluxDB up and running in my network, and decided to monitor all (well, all possible - the QNAP seems to be a problem) devices. That’s quite easy to do by installing Telegraf as a server agent, and add some configuration. Everything is deployed using Ansible, so I can re-use the same Playbook for many devices.

Let’s assume I have a laptop which I want to monitor. The hostname is sunlight (it’s not, I’m just using this as an example).


Cron mails from root@localhost

If your cron keeps sending mails from root@localhost (which is bad, if the mails are forwarded to another system), check your mailserver settings. In Postfix, your $myhostname setting should point to an existing and valid domainname.
