Hi guys,  
I’m working with PMM and MongoDB databases. I’m looking for “LOAD” metric - description how it’s calculcated. If i count all the queries from in Query Per Second field in some time range ( 12 hours ) for example, then calculation doesn’t match.

Can somebody help me to understand “LOAD” metric ?

Thank you

Hi @MixafeSVK ,

Welcome to the Percona Communiy!  
Here the load is calculate as QPS \* Avg Query time which indicates avg query load on the DB.

For eg.: If QPS = 1 and Avg execution time is 22sec. Then the avg. query exerts 22 points load on the DB.

Regards,
