Setup telegraf + Prometheus + Grafana on CentOS Linux release 7.7.1908 (Core).

[Kaushal Shriyan]

Hi,

Is there a way to configure telegraf push data to the Prometheus Time series database and render it in the Grafana visualization tool? I have setup telegraf + influxDB + Grafana on CentOS Linux release 7.7.1908 (Core). Any docs or tutorials to setup telegraf + Prometheus + Grafana ?

Any help will be highly appreciated and thanks in advance.

Best Regards,

Kaushal

You can't push to Prometheus like that.

Have a look at VictoriaMetrics, which *does* support push (including the influxdb line protocol used by telegraf). It also supports the Prometheus query API, so you can query it from Grafana dashboard just like a Prometheus server.

Hi Brian,

So Prometheus does not support telegraf. I am not sure if I completely understand it. InfluxDB is a time-series database while Prometheus is also a time-series database. Any plugin or module to allow telegraf agent to push metrics to the Prometheus time-series database?

Prometheus is not a time-series database. Prometheus is a monitoring system that operates on metrics and happens to include a very good time-series database to support this functionality.

Sorry if I wasn't clear before, but I can't think of a clearer way to say it: *you cannot push data to Prometheus*.

Prometheus is a pull-only system.  Prometheus connects to data sources to ingest data.

Telegraf has a plugin to act as a prometheus client. Then it can pull data from it:
