Return code of 127 is out of bounds. Check if plugin exists

[gsmith]

Once in awhile we run into issues if a plugin is written for Python2 and someone is running Python3
but we are able to deal with it on a case by case basis.

on the nagiosxi server run:

Code: Select all

which python

If it comes back with a filepath then:

Code: Select all

ls -l <filepath>

we may have to create a symbolic link from one of your installs to /usr/bin/python

[scpeterson]

which python
/usr/bin/which: no python in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)

Looks like I need to add a link to one of the versions of python then?

[gsmith]

Exactly.

Do a:

Code: Select all

ln -s /blah/blah/blah/python  /usr/bin/python

Use the python2 version please.

Thanks

That fixed my issue. I ran the command

Code: Select all

ln -s /usr/bin/python2.7 /usr/bin/python

as root, and everything started working again.
Thanks much for your help.
