AppNeta Performance Manager (APM) plots performance in real-time; no page refresh is required.
If you change an attribute essential to monitoring, i.e., source, target, target type, instrumentation, QoS, alert profile, a vertical line marks the point at which you reconfigured the path, or restarted the sequencer process.
Gray horizontal lines mark path alert thresholds. When a metric crosses a threshold, it is an event. In case of a violation event the area beyond the threshold is colored red. Whenever a non-default alert profile is applied, faint vertical lines mark the beginning and end of alert profile time ranges.
