Environment is sized as required by the Foglight for Databases Deployment Guide.
When monitoring a new database instance, the "Insufficient Resources" error message is displayed informing the Agent Manager has insufficient memory allocation.
Memory sizing estimation calculated by the instance installation wizard is not aligned to the information found in the deployment guide.
A message similar to the following appears
FGLAMNAME has reached its maximum memory capacity of X GB. In order to configure the selected agents, an additional Y GB are needed.
The installer system is adding the current load of the database agents without PI to the calculated load needed to support the PI extension. The total is higher than the JVM heap available in the system.
Temporarily change the registry value for DBSS-InstallerSPIAgentEstimatedMemorySizeMB from 80 to 20 (for SQL Server agents), then add all of the SQL Server PI extensions, and then change it back to 80 after this is complete.
For Oracle agents, follow the same step but use the DBO-InstallerSPIAgentEstimatedMemorySizeMB registry value.
This issue has been logged as FOG-2946 to be fixed in a future version of the SQL Server and Oracle cartridges.
