slow Metric
On our 13.5 OEM I'm seeing this:
The specific Metric which checks the tablespace usage of a given database, runs very irregular on certain databases, and very frequent on some other. For the slow Metrics, he also doesn't want to show any recent information, like the graph with the data of the last 24 hours. It just says no data ... while he has data for the last week and month.
On one of them, the last check timestamp is now 10 days old, on another one its 5 to days old. On other ones it's 10 minutes.
I really think it's not the Metric interval which is set to 5 or 10 days, the Metric doesn't seem to be active for long periods, without any logical method.
