Dell OpenManage - OMSDK error while using the plugin

[gcicala]

Good afternoon to everybody.
I've updated a Nagios system both for OS and for the application.
Now I'm running the 5.7.1 Nagios Xi release.
I've also updated the Dell OpenManage to the 3.1 release but while I try to launch this check I'll encounter this type of error:

# python /usr/local/nagios/libexec/dellemc_device_check.py

The omsdk package is the last one:
# pip search omsdk

Some of you have had the same problem?
Any advice?

OS: Red Hat Enterprise Linux Server release 7.8 (Maipo)
Nagios Core 4.4.6

Best regards.

Try doing this:

Code: Select all

yum reinstall python-urllib3 python-enum34 python-chardet python-requests

Then test, if it still doesn't work, try doing this:

Code: Select all

cp -rfp /usr/lib/python2.7/site-packages/urllib3 /usr/lib/python2.7/site-packages/urllib3.bak
mv /usr/lib/python2.7/site-packages/urllib3 /tmp/
yum reinstall python-urllib3

Then test again.

Hi ssax.

I've tried your hints and now the error message is different:

Code: Select all

# python /usr/local/nagios/libexec/dellemc_device_check.py
