My PMM is deployed in Docker and the version is 1.5.1 . OS is ubuntu 16.04

My MySQL is AWS RDS . The dashboard is MySQL Overview.

Some metrics become exception suddenly in short time .

Anyone occured it ? Is it a bug ? Thanks a lot .

How frequently does this happen ? It looks like abnormal jump in Questions counter which is reported by MySQL server.

Can you go to Advanced Data Exploration dashboard and pull out raw data for “mysql\_global\_status\_questions” as shown on the attached image

It should show if there is a problem with Raw data jump or something else.

The frequency of occurrence is uncertain . Not only this metrics is abnormal , other metrics is so .

The below is mysql\_global\_status\_questions and mysql\_global\_status\_commands\_total (command=‘insert’) in abnormal time .

What is real question ? Thanks
