OAM-PM Latency report

Overview

An OAM-PM Latency report can be run by itself or as a drill-down from an OAM-PM Network Site Summary report. The report shows the graph of latency for a selected session during a specified time period.

The report includes the following session types:

ETH-CFM Session
TWAMP-Light Session

Use cases

QoS analysis—Identify potential service impacting issues based on thresholds for latency, jitter and packet loss between specific NEs.

Report inputs

The following table shows the report inputs.

Table 13-8: OAM-PM Latency report inputs

Prompt	Notes
Session Type	ETH-CFM Session, TWAMP-Light Session
End Date	Calendar date or relative date (for example, two days ago) and time
Granularity	Aggregation types: None (raw collection interval) Hourly Daily Monthly
Report range	Length of time to be reported, in minutes (minutes, min), hours (hours, h), days (days, d), or months (months, m)
Source Node	Search using partial or full names. Select individual items or click Select All. Both the NE name and its IP address display.
Target Node
Session Name
Bin Type	Frame Delay—The Avg Delay, Min Delay, and Max Delay in the report output is the delay in microseconds Frame Delay Range—The Avg Delay, Min Delay, and Max Delay in the report output is the delay range in microseconds Inter Frame Delay Variation—The Avg Delay, Min Delay, and Max Delay in the report output is the delay variation (jitter) in microseconds
Interval Duration	5 minutes, 15 minutes, 1 hour, or 1 day
Threshold	Specify in bps/Kbps/Mbps/Gbps
