System Summary

The System Summary section of the dashboard provides basic information of the host machine.

This example illustrates the fields and controls on the Application Server System Summary. You can find definitions for the fields and controls later on this page.

Field or Control	Description
Architecture	The machine architecture.
Available Processors	The number of available processors on the machine.
Name	The operating system.
Total Physical Memory Size	The total amount of physical memory (in GB) available on the machine.
Total Swap Space Size	The total amount of swap space (in GB) available on the machine.
System CPU Usage (%)	A graphical visualization showing the CPU usage in percentage. Note: If the system CPU usage is consistently high, then investigate whether the host is overloaded. If so, add more hosts to share the workload.
Free Physical Memory	A graphical visualization of free physical memory size.
APPQ Requests Waiting	The number of requests currently in queue on the APPQ process.
APPQ Requests/Second	The mean number of requests processed the APPQ process during a recent time period.

The following table lists the APPQ process issues and their resolutions:

Symptom	Cause	Action
The graph consistently shows ten or more requests waiting for several minutes.		Add more servers for handling the load either by adding more server processes within the current domain or by adding more application server domains. Note: Ensure that server processes per domain are not more than forty five.
APPQ Requests/Second are low but APPQ requests waiting are high.	Some APPQ requests take time to complete.	Investigate whether the following factors are causing the delay: High number of data is being fetched. PSAPPSRV CPU usage is high. Network bottleneck. Disk usage, if I/O is involved.
Slow-performing requests.		Tune to improve the performance.
The throughput is slow for light requests.		Investigate whether the server lacks processing power. If so, move application server domains to a host with more CPUs and RAM, higher network bandwidth, and faster storage.
