^is that dashboard .json available anywhere on github?

I'm currently leveraging the nginx-ingress grafana chart, which shows all the Ingress Certificate Expiry results with a TTL on it. This might help?

But it doesn't show other interesting about cert-manager itself like overall requests per 2m, /acme/new-order, etc. other things shown in the grafana screenshot in the blog post. Would be cool if that could be shared (assuming it's it's freely available)

Found this post while looking for a cert-manager dashboard I can plug into my Grafana. I see the sample dashboard in the blog post but I don't see the dashboard json file. Anyone know where I can find it?

Thank you.

Will be great if someone can share the work on a cert-manager dashboard.

I threw this together the other day after running across the blog post. No idea if the graphs are accurate, but it's a start: https://grafana.com/grafana/dashboards/11001

Cool thanks a lot.
But can you share the dashboard externally as the datasource use some custom regex?

Thanks for dashboard, it works except "label_values(..)" query:

label_values(certmanager_certificate_expiration_timestamp_seconds{exported_namespace=~".*"},name):

"invalid parameter 'query': parse error at char 13: unknown function with name \"label_values\""

@munnerz do you mind sharing the dashboard json shown in the https://blog.jetstack.io/blog/cert-manager-0.6/ ?
Maybe we can even include it into the chart using the https://github.com/grafana/helm-charts/tree/main/charts/grafana#sidecar-for-dashboards. Something like the one here: https://github.com/helm/charts/blob/0c093133575d640710959d3442d5bad59c776942/stable/sealed-secrets/templates/configmap-dashboards.yaml
