Exadata: OS performance analyzing via ExaWatcher

The operating system statistics are collected in the Exadata environment using the tool ExaWatcher automatically. You can generate statistics reports over a certain time as user root:

The following example generates the report for the period from 09/24/2018 till 09/26/2018:

cd /opt/oracle.ExaWatcher

./GetExaWatcherResults.sh –from 09/24/2018_00:00:00 –to 09/26/2018_23:59:59

Results will be generated as the BZIP2 Archive in the directory /opt/oracle.ExaWatcher/archive/ExtractedResults.

The results can be analyzed very simple via Browser. You can unpack the archive, go to the directory and see separate directories for the different statistics:

In the sub-directory „Charts.ExaWatcherxxx“ you can find some html files. Open in the internet browser the file index.html and analyze the OS statistics via GUI:

You can see statistics in the following areas:

  • IOStat Summary
  • IOStat Detail
  • CPU Utilization
  • CPU Detail
  • CellSrvStat (on a Storage Cell Server)

One Example for the metric „CPU Utilization“:
