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

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.
The browser interface performance is poor (that is, it responds slowly). | |
The diagnostic snapshot for the Management Server shows that it is overloaded. | |
The browser interface performance is poor (that is, it responds slowly). | |
The Foglight® Management Server can be run on a virtual machine (VM), instead of physical hardware.
The following subsections describe some of the performance challenges the Foglight® Management Server might face in an environment that has interacting virtual components.
