As I mentioned on Monday today and on Friday we'll look at a couple of example reports which have been created for a Linux box.
Below is a simple utilization report for a Linux box running an application, it is for a day and it shows us that there are a couple of spikes where it has breached our CPU threshold.
Looking at this report we can see that these peaks take place during the middle of the day. Is that normal behavior? Do you know enough about the system or application that you are reporting on to make that judgment? Do we need to perform a root cause analysis? If we believe the peaks to be normal then maybe we need to adjust the threshold settings or if we are unsure then we need to carry out further investigation. Has some extra load been added to the system? Has there been a change? Are there any other anomalies that you need to find out about?
Remember when reporting don’t make your reports over complicated.
Don’t put too much data on to one chart, it will look messy and be hard to understand.
On Friday I'll show you an example of a report on disk utilization of a Linux server.
