we were trying to do Hot Sensor Placement with one new class in a sensor.
This message appeared in agent log:
2018-11-02 10:56:16 UTC [c74fc8c8] info [native] Hot sensor placement request for 0 class(es) (0 KiB) took 0ms. 2018-11-02 10:56:16 UTC [c74fc8c8] info [native] redefineClasses took 0ms. 2018-11-02 10:56:16 UTC [c74fc8c8] info [native] 0 error(s) occurred, 0/0 class(es) redefined in 0 step(s).
Also in the collector log we found this:
2018-11-02 10:56:10 UTC WARNING [ClassCache] Couldn't find all MetaClasses in classCache!: 150 2018-11-02 10:56:10 UTC WARNING [LoadedClasses] Not all classes loaded from classCache, those classes will not be hot sensor placed!
Any idea what that means? Why those classes can't be placed in the sensor?

Hello @David V.
Relevant class not included?
Therefore, check mark on the 'Integrate cached data from all collectors' and try again.
