Reporting › Device Context Views › Latency Trend

Latency Trend

The Latency Trend view shows you a trend chart of average round-trip response-time (latency) values. The values are collected from a series of ICMP ping tests to the indicated device.

Short-lived, intermittent changes in response-time values are typically caused by increases in queue delay along the network path. However, a device that is busy executing other, higher priority processes can delay responding to ICMP messages until the other processes have finished executing. Over the long term, semipermanent or permanent changes in latency can be caused by changes in the network path. Or these changes can stem from provisioning or by deprovisioning of interface bandwidth levels along the path.

By default, the Latency Trend view includes the following information:

Pingable Device

Is the IP address or hostname of the device that was the target of an ICMP ping test.

Avg Response

Is the average response time for the ping test, in milliseconds.

Average Response Projection

Projects the trend in future average latency, based on the average ping response-time data.

Resolution

Is the amount of time that each data point in the chart represents.
