Selecting the Milliseconds or Percentage threshold setting lets you specify a static threshold value for a particular metric. This value does not change unless you change it.
Static thresholds can be used to define target values for metrics that are highly consistent or that have known values for poor performance. For example, a healthy server should not refuse session requests from clients, so setting a static threshold of 1% refusals for Minor (yellow) and 3% for Major (orange) would prevent the management console from ignoring server issues on a server that frequently refuses sessions.
Other metrics that are good candidates for static thresholds are:
Using the Milliseconds or Percentage static-value setting also means that thresholds are no longer automatically separated out by network and by server. To resolve this issue, you must group networks with similar latency by network type and then assign a custom set of thresholds to each network type.
Before configuring a static threshold for a given application, view a report on the Engineering page, and use the Settings button to select the metric in question. Make sure you are not going to set any servers, networks, or applications at a permanently degraded threshold level without first taking note of their metrics and correcting any underlying issues.
