If we need to write a Prometheus alert for expiry time, what should the query be?

As this is label, it's quite difficult to write alert, Let me explore to handle this.

I need to use metric instead of label for this:
This is the alert query for certificates expiring within 1 month:
0 < (certificate_expiry_time{} - time()) < (30*24*3600)

I will add sample warning alert as well for reference.

That looks good. Also let's add a alert for expired certificates.

In this dashboard, root SVMs are excluded by default. Are we sure that root SVM certificates also need to be excluded for certificates?

So, While checking the security/certificates Rest call, there are no certificates records for root svms. We are good to go here.

Also, I would be adding the scope field, which shows cluster or svm to help customer to see the scope of the certificate.

Are you saying:
a) that root SVMs do not have certificates or
b) that ONTAP does not return certificates for root SVMs

I think you're saying that root SVM have certificates, but ONTAP is not returning them? If that's the case, we should check the expiry for root SVM certificates some other way

So, there is little correction on my above note.

  • Out of admin and node svm (which we treat as root svm), admin svm can have certificates
  • But, It's cluster scope and not svm scope, (scope is only in Rest) which means we don't get svm name in certificate in Rest calls.
  • We would do little more work to get those detail in Rest, which we are already doing in existing plugin, and we have this comment as well for that reference.
    // Admin SVM certificate is cluster scoped, but the REST API does not return the SVM name in its response. Add here for ZAPI parity
  • As there are cluster scoped and svm scoped certificates in table, I need to remove the svm filter from query,
    So, even the SVM drop down have limited svms but this table shows certificates from all of them.

Just to note, Above the table the stats count is showing those admin svm's certificates only(admin svm is unique in cluster) and not all of them.
