Dashboard MySQL Performance Schema Details: values in Index Access Operations (Load) graph

[Spinner97]

Hello there,

I’m looking for a description I couldn’t find in the documentation about a graph in a dashboard (see title). Coul you provide a definition of what this graph displays? Furthermore, the values I have at the side are quite confusing. I have a lot of “insert NONE databasename.tablename” and I can’t figure out what is the meaning of this statement (this is not valid SQL AFAIK).

Thanks for your help!

Hi @Spinner97

The graph is based on metric mysql_perf_schema_index_io_waits_seconds_total

So should search a description for table table_io_waits_summary_by_index_usage

Thank you,
