Monitoring your system is important to maintain high availability,
but monitoring consumes system resources. You must carefully consider
your performance needs against your need to know as soon as possible
when a failure threatens availability.
System Performance Issues |
 |
The primary performance impact will be related to the polling
interval and the number of resources being monitored. You need to
balance your need to quickly detect failures with your need for
system performance and adjust the number of resources you monitor
and the polling intervals accordingly.
You may want to set a short interval, such as 30 seconds,
for resources that require quick response after failure. You may
want to set a longer polling interval, such as 5 minutes or more,
for all other resources.
Network Performance Issues |
|
Although monitoring is not likely to affect network performance,
you may want to make sure that only necessary messages are being
sent. Make sure your monitor requests are configured so you are
notified only for important events.
