Configuring APS thresholds manually

Metric thresholds can be set manually when initially creating the APSApplication Perfromance Score object or upon editing an APS object even if they were automatically determined by the baselining operation. For example, if the baselining operation set all of the thresholds and you really only care about round trip time, normalized server delay, and normalized network delay, then you can remove the threshold settings for the other metrics.

1. Go to Configuration > Objects > Service Levels > Application Performance Score.
2. On the Add New APS Object form, uncheck the Auto Baseline checkbox. Note if a baselineused by monitors and performance reports to establish a standard by which sunsequent performance can be measured analysis is running, you'll need to press the Stop Baseline button. The threshold values are only editable there is not a baseline running. The metrics will appear on the screen. Or edit the APS object in the list, then on the Edit APS Object form, the Scoring Metrics appear at the bottom of the form.
3. Enter or modify the values for the metrics that you are interested in setting thresholds for. Note that any metric that does not have a threshold set will not be analyzed when calculating the APS score.

• Network delay – the time taken for data to traverse the network (on the wire) in one direction from the client through the Exinda appliance to the server (or in the opposite direction) in ms
• Server delay – the time taken for a server to respond to the request in ms
• Normalized network delay – the time taken for data to traverse the network in one direction, where the delay is measured independent of the transaction size by assuming a normalized packet size of 1024 bytes
• Normalized server delay – the time taken for a server to respond to the request, where the delay is measured independent of the transaction size by assuming a normalized packet size of 1024 bytes
• Round-trip time – the time taken for a packet to travel from a client through the Exinda appliance to the server and back
• Jitter – the measure of variability of network delay, defined as one standard deviation of normalized network delay
• Inbound loss – the percentage of packet loss on inbound traffic
• Outbound loss – the percentage of packet loss on outbound traffic
