Performance Graphs
System Load Average
The number of jobs currently waiting to be processed. Load is a rough metric that
will tell you how busy a server is. A typical AirWave load is around 2-3 times the
number of CPU cores you have in your system. A constant load of 4x to 5x is cause
for concern. A load above 6x is a serious issue and will probably result in AirWave
becoming unusable. To lower the load average, try increasing a few polling periods
in the Groups > Basic page.
