total_cpu_usec

Y

bigint

Microseconds of CPU time consumed by the data server.  Divide by 1,000,000 to scale this as seconds.

CPU consumption is a good indication of how much work is being done.  All activities, including overhead such as compiling queries and utility work are reflected in CPU consumption.  Inefficiencies that increase the cost of doing business, such as excessive recompilation or lock contention can sometimes be seen by observing that CPU consumption has risen disproportionately to the amount of useful work that is being accomplished.

act_completed_total

Y

bigint

Activities completed by the data server.

Activities typically correspond to a query.

The number of activities completed is a measure of work accomplished.

rows_read

Y

bigint

Rows read is a good indication of how much work is being done by queries.  Non-query work such as utilities and overhead for internal activities of the data server is largely excluded from rows read.  So it is a better measure than CPU time for evaluating how much useful work is being accomplished.

rows_modified

Y

bigint

Rows modified includes updates and deletes of table data.  Modifying data is much more expensive than reading it.

rows_returned

Y

bigint

This is the number of rows returned to the client by queries.  Excessive amounts of data returned to the client can indicate a run-away query (cross product, missing filters) or abuse (people in the process of making unauthorized copies of the data) or even bad practices such as mis-guided attempts to pull large portions of the data into a spreadsheet or an application for post processing that could be better done inside the server.
