--: There is no related parameter.
- #1
-
This is the average time spent for the following request processing excluding creation of redundant copies of data:
-
put and remove processing
-
create, update, or replace processing to update data
-
- #2
-
This is the time required to process the entire request (put or remove processing or create, update, or replace processing to update data) on the first EADS server whose data is manipulated.
- #3
-
During restoration or scale-out processing, the following data is sent to the EADS server subject to restoration or the EADS server that was added during scale-out processing:
-
Data to be copied
-
If data was updated after restoration or scale-out processing started, a notification of the update operation
-
- #4
-
The digits after the decimal point are truncated.
(2) Sources for statistics used for EADS server performance measurement
The following figure gives an example of put processing, which shows the sources of the statistics used for EADS server performance measurement.
Explanation
-
The EADS server determines the request processing time based on the difference in time between Nos. 1 and 4. The EADS server also obtains the following statistics:
-
Maximum request processing time (RequestProcessingMaxTime)
-
Average request processing time (RequestProcessingAverageTime)
-
Minimum request processing time (RequestProcessingMinTime)
-
-
The EADS server determines the time spent on consensus processing based on the difference in time between Nos. 2 and 3.
-
The internal processing time equals the request processing time minus the time spent on consensus processing. The following statistics are obtained:
-
Average internal processing time (InternalProcessingAverageTime)
-
