Monitoring non-OSA Servers
To limit the resources consumed by each
NodeService a configuration parameter
simultaneousCdPollers in the
data, whose default value is 7, is used.
For optimum performance
simultaneousCdPollers is typically set to 25% of the
number of total number of polled monitored server types assigned to each EP with a maximum value of
30. This is just a guideline and not definitive however.
Enable the built-in rule Monitoring rate out of compliance, which uses
these events in a linked rule to know when polling rate of any non-OSA server is not occurring at
the expected rate for over an hour. This rule is often triggered because
simultaneousCdPollers is set too low for activity being monitored and/or the number
of monitored servers is too high.
The following sections describe how non-OSA servers are monitored and their performance implications.
