Thresholds View
In the Thresholds view, you can see the service level agreement (SLA) state of the service that you selected in
the Inventory. You can also enable and disable SLA monitoring and change the SLA threshold settings. The
thresholds that you specify affect when events are generated.
Thresholds are the service performance values that you specify that should not be exceeded if service level
agreements SLAs are to be met. You must have thresholds defined for an object before you can monitor its
performance.
By default, AppSpeed specifies threshold values. AppSpeed monitors performance of services and servers and
defines thresholds based on the monitored data. You can manually define thresholds. You can also change
thresholds that AppSpeed specifies or that you specify manually.
See
"SLA Monitoring,"
Events View
The Events view provides a list of instances when SLA states for a selected service or server changed from one
state to another.
After SLA thresholds are specified for a service, and SLA monitoring is enabled, deviations from the SLA
thresholds generate events. Events are listed in a table that is available in the Events view of the Inventory
module.
See
"Viewing Events,"
Define the Time Frame for Data Collection
You can select a predefined time frame, such as a day or week, or you can specify the start and end times and
dates for which performance data is displayed.
The specific units of time in which the data is displayed depend on the data time frame that you select.
The length of time that aggregated data is stored in the AppSpeed internal database depends on the selected
time period.
