Hi @Vadim_Yalovets ,
Sorry for the late response, yes I checked that as well some time back and we have data in this table for the monitored mysql instances:
And I actually wanted to get you up to speed with all the troubleshooting that we did at our end, for which I had several screenshots to share with you, but unfortunately the forum portal doesn’t let me add more than one image or even attach a single file that has several screenshots 
It would be great if I can work around this problem somehow.
Thanks,
Nikunj
