MongoDB and LOAD ( average active queries )

[MixafeSVK]

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.
