The PostgreSQL performance warehouse at one customer keeps growing at daily rate of 3 - 4 GB at one customer. It is now about 265 GB and it just keeps on growing. I have checked that the maintenance task executes successfully. The data retention is the default and the size of the deployment is about 250 agents, so not huge. The deployment has been running for a few months now, so it should more or less stop growing rapidly as it is doing now.
Is this a normal behavior? Anything I should check? Any suggestions?
We can roughly calculate with a total space of 2 GB needed per 1,000 Measures, so according to this calculation we can perform a test run with your System Profile and get the number of measures from the chart. This gives us a real number and you will not need to estimate.
