Exadata troubleshooting easy with GetExaWatcherResults.sh

If you have for example a performance problem or a crash on your Exadata Machine and you need an overview about the machine then use the very powerful tool „GetExaWatcherResults.sh“ which based on the data of Exawatcher.

GetExaWatcherResults.sh give you a details about:

• CPU utilization and details
• IO Summary
• and more

GetExaWatcherResults.sh will generate very good graphics and that is what I will show now.

How is the way to get these graphs?

Login as "root"

cd /opt/oracle.ExaWatcher

GetExaWatcherResults.sh --from 02/23/2018_08:00:00 --to 02/23/2018_13:00:00 --resultdir /tmp/exawatcher_230218

Next step

cd /tmp/exawatcher_230218

bunzip2 the archive and un tar it

tar xvf ExaWatcher_exa31_2018-02-23_08_00_00_5h00m00s.tar

 

Change to the newly created directory and you find the following files

index.html
exa31.net_cpu.html
exa31.net.html
exa31.net_iodetail.html
exa31.net_iosummary.html
exa31.net_menu.html
exa31.net_mp.html

 

Start a Browser on the Server or copy the files to your notebook and start analyzing

open the "index.html" files

It is easy to answer questions like

• What is the CPU usage on Friday between 09:00 an 14:00 o’clock?
• Where do we have a CPU peek during the business hours?

No problem with „GetExaWatcherResults.sh“ and if needed go deeper with other tools for example „awr – report“ on the database itself or an „ash-report“

Try it. It’s very helpful :-)
