Can you please create a product idea for this use case with some details:
For example: Could we create a synthetic monitor and check for the certificate? Do you want to get the alert X-days before it expires or just if it is expired?
At the moment Dynatrace can't do that.
This works really well, but it would be good to be able to schedule the frequency for more than once an hour. Once a day or even once a week would be frequent enough to check for the certificate expiration. Can we get a longer time for these tests, please.
@Bill_Demsky totally agree with your request !
Till this request will be full fill you can try utilize Maintenance Window to suppress the running of synthetic checks.
Tried that and its look its working OK
Another way to run it every now and then will be by using API: Synthetic - On-demand monitor executions
