Message Latency

Message latency is a measure of the time that a message spends inside the Rhapsody engine. You can view message latency statistics from the Management Console.

Generating or Exporting Reports

To view or export Message Latency statistics:

1. Navigate to Reports>Message Latency to display the Message Latency page:

    

2. Enter the following details:

   Field	Description
   From	Enter the start date and time for your generated report (set to 24 hours before the current time by default).
   To	Enter the end date and time for your generated report.
   Time Zone	If you want to export the data using UTC (Coordinated Universal Time) as the time zone, select the Export Times Using UTC checkbox. If this option is not selected, the data is exported using the local time of the Rhapsody engine, which could potentially result in time discrepancies if a daylight saving changeover occurs during the period the statistics were collected.
   Input	Select an input communication point receiving the message from an external source.
   Output	Select an output communication point from which the message left Rhapsody.

3. Choose one of the following options:

   If you want to	Then...
   Generate an on-screen display of the collected statistics	Click the Generate Report button. Refer to Message Latency Report for details.
   Export message latency statistics	Click the Export Raw CSV Data link. The data is exported as a zipped .csv file. You must have permission to export message latency statistics to view the Export Raw CSV Data link.

4. When you have finished, click the Discard Report link to clear the Message Latency report.

Message Latency Report

The Message Latency report includes a chart displaying the variation in the average time spent by the message in the Rhapsody engine, in milliseconds. The table below the chart lists the message count, mean latency period, standard deviation (a measure of how much the values deviated from the mean), and minimum and maximum processing times.

Message Details

By clicking the View Message link, you can open the Message View page to display the details of the message taking the longest time to process in any of the chart's time divisions. Message View can be useful for debugging, for example determining why some messages are slower than expected.

Zoomed View

You can zoom into a particular section of the graph by selecting the section with your mouse. By clicking the Reset Graph link, you can reset the zoomed in view of the messages.

Data Points

By placing your mouse pointer over any a data point on the graph, you can view the actual latency period at that point in time.
