Foglight 5.9.7 - Performance Tuning Field Guide

Identifying Performance Problems

There are two main methods you can use to proactively check the performance of a Foglight® installation:

Hardware and Operating System Tuning

Foglight® processes and analyzes observations and presents them to users. This is resource intensive. Even if you perform the tuning exercises described in other sections of this guide, the overall resource use of the Management Server might still eventually exceed that which the underlying operating system and hardware can support. However, you can increase Foglight performance linearly by putting Foglight on faster hardware (that is, more CPU and increased I/O) or by increasing the physical memory available (see Java Virtual Machine Tuning ).

For the minimum Management Server hardware requirements, refer to the System Requirements and Platform Support Guide.

Running on Virtual Hardware

The Foglight® Management Server can be run on a virtual machine (VM), instead of physical hardware.

If you are going to run the Management Server on a VM, ensure that the Management Server is well-tuned.

Performance Challenges

The following subsections describe some of the performance challenges the Foglight® Management Server might face in an environment that has interacting virtual components.

The information in the following subsections helps you optimize the performance of the VM in which the Management Server is running. However, as the performance demands of monitoring the virtual infrastructure increases, so do the underlying processing requirements.
