define alert rule for missing GDC metadata archive #13

Open tomkralidis opened 4 months ago

tomkralidis commented 4 months ago

In cases where a GDC does not produce a metadata archive zipfile on a daily basis (noting the 24 hour retention time for GC), there exists a risk / gap in not being able to cold start a GDC from a known archive. Consider raising an alert in this case.

What are suitable solutions for this?

GC providing a metric with the time stamp of the last time it received the archive?

Consider how the GDC can ensure that the archive is complete and unzipable before sending it

I was wondering if this is a duplicate of #16 ?

Do we need two metrics, one for metadata and one for the archive? See also the comment from @aschremm in #16 I only recall that we wanted to have an alert when the archive is not received by the GC for more than 24 hours....
