III. Data acquisition

The above implementation is the real-time monitoring of the server. In the actual performance test, we need to record the data within a period of time, you can use the following command

. / nmon-f-t-r test-s 30-c 10-m / opt/oracle/nmon

The meaning of the above command is:

-f: output file name in standard format: _ YYYYMMDD_HHMM.nmon

-t outputs the processes that consume the most resources

-s: sampled every n seconds, here is 30 seconds

-c: how many samples are taken out? here it is 10, that is, monitoring = 10 / 30 / 60 / 5 minutes.

-m: directory where the nmon generated files are located

-h: more help

Test: title of the monitoring record

After the command is started, the monitoring file is generated in the directory where the nmon is located, and the resource data is continuously written until the collection of the 360monitoring points is completed, that is, monitoring for 1 hour. These operations are completed automatically without manual intervention, and the testers can continue to complete other operations.

If you want to stop the monitoring, you need to query the process number through "# ps-ef | grep nmon", and then kill the process to stop monitoring.

The nmon output file is named server name _ date time .nmon

Convert the .nmon file to a .csv file and generate the corresponding .csv file in the current directory with the following command

Sort BOSS1_110810_1438.nmon > BOSS1_110810_1438.csv
