In Cloud Pak for Data as a Service, you cannot see newer queries in the Data Virtualization cache dashboard or the
cache metadata is not being updated for existing caches.
Symptoms
You notice that the cache hit count or the last used timestamp are not getting updated for all the caches. You also notice that newer queries are not appearing in the Responsiveness histogram or the Queries tab of the cache dashboard.
Causes
It is likely that event monitoring is turned off from the monitoring console. Event monitors are used to find recently run queries and their cache usage, and queries by cache recommendation engine.
Resolving the problem
Go to and ensure that event monitor collection is turned on. It might be turned off for various reasons such as low table space.
