ssl_exporter dont export timestamp to prometheus about ssl_exporter

[britcey]

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.
