Performance Report

The server statistics in buckets can be accessed using the perfdump utility. The performance buckets information is located in the last section of the report returned by perfdump.

The report contains the following information:

• Average, Total, and Percent columns give data for each requested statistic.

• Request Processing Time is the total time required by the server to process all requests it has received so far.

• Number of Requests is the total number of requests for the function.

• Number of Invocations is the total number of times that the function was invoked. This value differs from the number of requests in that a function could be called multiple times while processing one request. The percentage column for this row is calculated in reference to the total number of invocations for all of the buckets.

• Latency is the time in seconds the Proxy Server uses to prepare for calling the function.

• Function Processing Time is the time in seconds Proxy Server spent inside the function. The percentage of Function Processing Time and Total Response Time is calculated with reference to the total Request Processing Time.

• Total Response Time is the sum in seconds of Function Processing Time and Latency.

The following example shows sample performance bucket information available through perfdump:
