From which metric InnoDB Main Thread Utilization parameter graph is collected data and which parameter is behind the scenes, is it os level or innodb itself?  
in which parameters is it looking for in background?

```auto

Log Flushing: mysql_info_schema_innodb_metrics_server_innodb_log_flush_usec_total
Insert Buffer Merging: mysql_info_schema_innodb_metrics_server_innodb_ibuf_merge_usec_total
Checkpointing: mysql_info_schema_innodb_metrics_server_innodb_checkpoint_usec_total

```

Hello @Nanuka,  
Looks like this was implemented here:

So these all come from information\_schema.innodb\_metrics table.
