Goal: To use my existing Grafana instance to visual data from AdguardHome DNS which uses a Prometheus database for metric storage and the AdguardExporter software application which scrapes the Adguard API and pushes the data to Prometheus.
A friend of mine and myself run some Grafana instances to monitor various things vi Telegraf. John was having some storage space issues on his machine and noticed that in our default installations, we had never set the data retention policies beyond default which keeps them forever!
Below is John Mora’s write-up of addressing the issue, Thank you sir!
I have used the process as documented and unsurprisingly it fixed my problem as well.
