This chart is based on the Helm Chart provided here: https://github.com/foomo/pagespeed_exporter/tree/master/helm/pagespeed-exporter But this provides more options like:

• Execute the scraping via cronjobs
• Store the results using Prometheus Pushgateway

You can check the available values with the command:

helm repo add softonic https://charts.softonic.io 
helm show values softonic/pagespeed-exporter

You need to get a valid API Key from Google from this URL: https://developers.google.com/speed/docs/insights/v5/get-started

Once you have it you can use it in the chart exporter.googleapikey. On other hand you just need to provide the number of targets in exporter.targets[].

You can activate the metrics scraping using one of the methods below.

NOTE: Be sure you don't activate both systems or you'll end up with more metrics than initially planned.

If you have Prometheus Operator on your side you can activate the serviceMonitor.enabled flag and fine tune the other default values based on your needs.

In case you want to make this to use the Prometheus Pushgateway you just need to define the URL exporter.pushGatewayUrl and enable the cronjob with cronjob.enabled flag.
