Hitachi Ops Center​

Nice one!

A small note, which could be my complete inexperience with Automator so far.

I seem to have to change the Python interpreter path as in service.xml it is set to /usr/local/bin/python3, overriding the default set for python in Administration > Shared Properties Settings in Automator.

Yes. This automation uses python 3.6+.

I tried and tested this on Opscenter 10.3 Ova.

Just wanted to check, its working fine for you now right?

Thanks for the feedback :-)

Thanks William, I found the plugin-doc pointing to Python 3. Sadly, on this RHEL7.8 install the default python version for python is 2.7 (in $PATH). I do have /bin/python3 as 3.6.8 so I expected this to work but so far no luck yet. Might be some missing dependencies somewhere. I'll have to dive into this when I find more time.

Yes that should work. I believe the only additional packages I use is the requests package.

So, you might need to:

• 'Copy and Edit' this version. Head to the python plugins and change the interpretor on the plugin to use your local python3. Creating a symbolic link to /usr/local/bin/python3 might also do the trick.
• Install requests in python. If you have pip3 available you should just be able to do a pip3 install requests

If that doesnt work we can always schedule a teams/webex/zoom session. This way we can solve it for the next guy :-)

Moved here with the latest version:
Community Automator Library - CPU Load Balancer

Hi, first of all thanks for the Service Template! So far I have managed to setup the Automator and import the Template. But when i click on "submit and view task" it runs into some Errors. Maybe somebody can give me a hint how to solve the Problem? Below the Errors from the Log. I have also tried to solve the problem with the installation of python 3.6.11 and changed the python interpreter path to python3. That changed the below Error Messages. But it still didn't work. Is a specific Python Version needed for the Template?

Thanks in advance!

Hello Miran

What Ops Center version are you running? 

Looks like the python path you're using doesn't have requests installed. If your ops center hosts has internet access could you do a "pip3 install requests"? Should solve the dependency. 

Hello William, thanks for your super quick reply! We have the latest OPS Center Version installed >> 10.9.3. Requests should be installed:

[root@LNZOPSC01 ~]# python3 -m pip show requests
Name: requests
Version: 2.13.0
Summary: Python HTTP for Humans.
Home-page: http://python-requests.org

Maybe wrong version?

Regards

Weird, might be that with my previous version on Ops Center it was included.

You could try a pip3 install urllib3.

Hi,

finally i managed to get it running without any error. I have installed urllib3 into my python3 Version. 

Here some output from the log:

May i ask some questions about how the Template works or maybe for a link for Template Documentation? 

Questions:
- Which timeframe does it use to analyze the MP Load differences? (last 10 Minutes, or longer?)
- According to the above log, did the template anything? On one hand it shows that it needs adjustment by about 6 % on the other hand it notes "Average: 0.0... 0 so please add: 0.0..." What i've done is the following... []

Thanks for your time!

Regards

Miran
