Sun Management Center Server with the Performance Reporting Manager Add-on

The Sun Management Center performance reporting manager (PRM) add-on is used to track historical trends and generate reports for any data property being monitored by Sun Management Center agents. The PRM add-on can have a significant impact on the sizing requirements of the Sun Management Center server since it can involve the collection and processing of large volumes of data.

The impact of the PRM add-on is shown in the PRM segment of Figure C–1. In general, increasing the management activity and the total number of data properties being tracked by PRM reduces the number of agents that can be managed by the Sun Management Center server.

Determining the requirements for a Sun Management Center server with the PRM add-on requires two steps.

1. Based on the total number of agents to be managed by Sun Management Center server with the PRM add-on installed, refer to the PRM segment of Figure C–1 to determine the required machine class.

2. Based on the estimated number of PRM data properties you want to collect, determine the appropriate PRM configuration as described in the following section.

Generating Performance Reporting Manager Reports

A wide range of reports can be generated by specifying different numbers of agents, numbers of data properties, and report durations such as 4 hours to 1 month.

Typical reports take a few seconds to several minutes to generate. The actual time required is affected by the following factors:

• The number of actual data points included in the report

  ---

  Note –

  Reports are limited to a maximum of 10,000 data points per report.

  ---

• Amount of performance reporting manager data in the database

• Server performance and activity

• Concurrent generation of other performance reporting manager reports

For example, on a medium Sun Management Center server configured with the performance reporting manager add-on, a relatively simple report that includes 5 properties for 1 agent over the last 24 hours can be generated in about 20 seconds. Conversely, a more substantial report that includes 5 properties for 5 agents over the last 7 days can take around 10 minutes to generate.

A medium Sun Management Center server with the performance reporting manager add-on is assumed to be a SunFire x4200 with two 2200 MHz x86 CPUs or a SunFire-v440 with two 1281 MHz SPARCv9 CPUs, 1 GB RAM, and 1 GB swap. It is also assumed that the server is monitoring 300 agents and collecting 300 data properties per agent for the performance reporting manager.

Scheduling Performance Reporting Manager Reports

If a report takes more than 30 minutes to generate, it is recommended that you schedule the report to run between 4:00 AM and 8:00 AM. Scheduling large reports to run after 4:00 AM reduces the load on the Sun Management Center server during normal business hours, and also can reduce the chance of conflicts with the nightly Sun Management Center and performance reporting manager tasks that typically occur between 12:00 AM and 4:00 AM.
