OS Montior Fetches the data using service SAPOSCOL and it displays CPU Utilization, Memory Utilization and disk response time.
The CPU idle time should not be less than 30% , If it is below 30% we can consider the following.
- The ABAP programs are expensive with multiple conditions and endless loops.
- The CPU is not sufficient to handle the load because the hardware is not procured as per sizing.
- Probably the hardware is procured as per sizing but the number of users grown dynamically (300-600). In this scenario we advice to deploy additional instances.
- If the programs are expensive then refer to development team. It also displays the memory installed on the machine, Memory available(Free) along with the SWAP space. Ensure that physical memory free is available to handle the user requests. If not memory bottleneck.
