LPAR AIM Monitoring Recommendations

The LPAR AIM (Application Insight Module) is a pluggable component that is implemented within the SystemEDGE framework. As such, the data that it publishes is available to multiple SNMP Managers. Products such as CA Virtual Assurance, eHealth, and Spectrum IM can leverage this data.

The following section specifies the scalability recommendations for LPAR AIM monitoring.

Scalability Recommendation for LPAR AIM Monitoring

One LPAR AIM can handle P systems environment configurations in the following range:

• Number of HMC Servers: 1 to 4
• Number of Power Systems per HMC Server: 2 to 10
• Number of Virtual I/O Servers per Power System: 1 to 2
• Number of LPARs per Power System: 10 to 100

General recommendations for LPAR AIM monitoring present a typical configuration of LPAR environment:

• Monitored Power Systems: up to 20
• Monitored VIO Servers: up to 30
• Monitored LPARs: up to 300

The AIM consumes CPU and Memory which is roughly a function of the number of LPARs. With a maximum of 300 LPARs the CPU consumption of the sysedge process would be less than 10 percent.

Note: The presented CPU consumption is valid for a dedicated SystemEDGE agent not running any other AIM.

With 300 LPARs added to the LPAR AIM, the sysedge process memory consumption increases by approximately 8 MB.
