Chapter 4: Enterprise Monitoring 69
Summary
It is impossible to operate servers running Exchange efficiently if you do not know what
they are doing. It is very important to ensure that you always have enough information
about your Exchange environment to predict problems and to verify that you are meeting
your service level agreements. However, there is such a thing as too much information.
Servers running Exchange can produce a huge amount of information, much of which is
unnecessary in a healthy Exchange environment. If your monitoring is to be useful and
efficient, you need to ensure that you collate useful data, have an understanding of what it
means, and are prepared to increase or decrease logging levels according to what is re-
quired at that time.
When monitoring Exchange, do not restrict yourself to real-time monitoring. Use recorded
data to perform trend analysis. Doing so allows you to prove that you are meeting your
SLAs and alerts you to potential problems in the future.
In larger scale environments, seriously consider a centralized approach to monitoring. This
helps to ensure that information about problems is available in the data centers where
more expertise is available. It also allows you to compare similar servers running Exchange
for performance and to get a consolidated picture of your Exchange environment.
