How do send prometheus discrete metrics with date?

Hi I’m new here and I’m not familiar with the domain language, apologize for any imprecisions.

I’m trying to use prometheus + grafana to monitor an external batch job to which I have no access nor control. The only feedback I get from the job is a log with a unix timestamp of last execution and number of errors.

1599282036, 0

I’m starting scraping the log to send the values to our prometheus cluster but I’m not sure how to generate readable metrics.

Can I expose to prometheus not only a metric like “number of errors” but also the date when this happened?
