Sun Management Center 3.5 Installation and Configuration Guide

CPU Resources

Sun Management Center agents add a minimal computational load on the host system. The computational load is caused by normal management operations, including periodic data acquisition, alarm rule processing, alarm annunciation, alarm action execution, and the processing of client requests.

The amount of load introduced is proportional to the rate at which data is gathered, the amount of data gathered, the number of alarms detected, and the number of user requests. The percentage of CPU resources consumed therefore depends on the number and type of modules loaded on the system, the configuration of these modules, and the computational capacity of the host system.

Even on low-end machines with a comprehensive suite of modules loaded and high management activity, the agent should never consume more than a fraction of the CPU resources.

The following table provides estimates of CPU and RAM usage.

Light configurations are based on an agent with the following modules loaded:

The heavy configuration is based on an agent with the following modules loaded:

  • Config Reader

  • Health Monitor

  • Full Kernel Reader

  • MIB-II Instrumentation

  • Directory Size Monitoring

  • File Scanning

  • Hardware Diagnostics Suite

  • Script Launcher

  • HP JetDirect

  • Agent Statistics

  • MIB-II Proxy Monitoring

  • Various other modules, including custom modules

The heavy configuration is likely to be greater than needed. Larger machines typically have larger hardware configurations with more processors and disks. These configurations result in greater memory consumption by agents running on larger machines.
