ssl_exporter dont export timestamp to prometheus

[petersg]

Hello all,

I have configured ssl_exporter to check some certs and display it into prometheus -> grafana.

My job config: `- job_name: "ssl" metrics_path: /probe params: module: ["https"] static_configs:

• targets:
  • "helloworld.letsencrypt.org:443" relabel_configs:
• source_labels: [address] target_label: __param_target
• source_labels: [__param_target] target_label: instance
• target_label: address replacement: 10.10.20.14:9219 ` If i check the route with(http://127.0.0.1:9219/probe?module=https&target=helloworld.letsencrypt.org:443) i can see that is correctly scraping it with the timestamp: But when i go to prometheus and see the output: Is missing the timestamp so i can not visualize the remain time to expire and others. It can be because it is out of the {}?

Kind Regards, Petar

The timestamp is the value of the metric - it's not one of the labels. It's a Unix timestamp (seconds since midnight Jan 1, 1970).

ssl_cert_not_after - time()

will give you seconds until expiration

(ssl_cert_not_after - time()) / 86400

will give you days until expiration, etc.

You can use 'humanizeTimestamp' in your alerts to show the actual date of expiration. I include an annotation like:

expiration_time: |
        {{ with printf "ssl_cert_not_after{serial_no='%s'}" .Labels.serial_no |query }}{{ . | first | value | humanizeTimestamp }}{{ end }}

Ok solved, it seems that grafana cant read correctly the $instance and $job but removing this or hardcoded it fix the issue.
