Prometheus - Documentations

[jdalia001]

Hello,

I would like to send metrics from my prebid server to prometheus but i don't find any documentation on it.
It just see in the config.go som parameters on this, but what is the configuration to set in prometheus to retrieve datas ?

Thanks

Prometheus is a pull based metrics system. The configuration you see in Prebid Server will turn on collection of Prometheus metrics with the app and expose an endpoint on a port of your choosing. You will then configure your Prometheus server to connect to your Prebid Server instances and read the metrics.

I don't know the details on how to configure a Prometheus server. I recommend starting with their FAQ.

The relevant settings in Prebid Server (in environment variable form) are:

// The port of the endpoint you want Prebid Server to host. There is no path. Connecting directly to this port will return a metric result set for Prometheus to consume. I do not recommend exposing this to the internet.
PBS_METRICS_PROMETHEUS_PORT: "9100"

// The main prefix Prometheus will add to the metrics to ensure uniqueness within your cluster.
PBS_METRICS_PROMETHEUS_NAMESPACE: "prebid"

// The secondary prefix Prometheus will add to the metrics to ensure uniqueness within your cluster.
PBS_METRICS_PROMETHEUS_SUBSYSTEM: "server"

// The amount of time Prebid Server will allow for the Prometheus endpoint to respond. You only need to worry about this if you metrics enabled which have high cardinality.
PBS_METRICS_PROMETHEUS_TIMEOUT_MS: "30000"

Thank you for your reply, yes i know how prometheus is working.
Do you know someone who integrate prometheus with pbs ? (Because we need to have a prometheus module to import datas correctly in it)

Yes. We're using Prometheus at Xandr with PBS. We have a separate team which manages the Prometheus system, so I don't have details to share in that aspect.

Are you able to configure the Prometheus module within PBS using the config I shared earlier?

With the docs PR open, can we close this @Mouchii ?
