Issue/Introduction

Can we analyze the current usage to ensure we have allocated enough space?

Environment

Release : All Supported Version

Component : CA System Agent

Resolution

If you know how java memory works heap only grows and rarely shrinks. So if the max heap size is set to say 4GB first java will reserve 4GB of virtual memory but it will only allocate and use a small portion this is what is shown in the simple health monitor log(simple_health_monitor.log)

Maximum allocateable: 3529 MB    0 KB    0 B
Total allocated heap:  108 MB    0 KB    0 B
Currently free heap:    81 MB  248 KB  512 B
