What is this alert?
When the master host memory usage is higher than the specified percentage for more than the specified number of minutes, Command Center raises an alert.
Command Center samples the memory in use on the master host every fifteen seconds. Memory used for kernel buffers and cache is excluded from the calculation. An alert is raised if the samples collected during the number of minutes specified are all higher than the specified percentage.
What to do
Use the ps command to identify non-database processes consuming excessive memory and stop them or relocate them to other servers.
If Command Center is running on the master host, restart it on the standby master host.
