That is the wrong redfish library. In the description of the plugin is written.
pip3 install python-ilorest-library
Until now i had no time to test if it can be rewritten to work with the generic redfish lib. This is used by my Lenovo xClarity special agent as the example from Lenovo also used this lib.
Hello Andreas, I have already python-ilorest-library version 3.2.2 is installed, but than (without any redfish module) this mistake appears:
File “/omd/sites/devel2/local/share/check_mk/agents/special/agent_ilo”, line 29, in
from redfish import RedfishClient
ModuleNotFoundError: No module named 'redfish
I am not familiar wiht python, but in code of agent_ilo files it looks for module “redfish”…
The problem is that the module naming is a little bit confusing between the only “redfish” module and the “python-ilorest-library”.
From your other post i see that you also installed the redfish module by itself. That is the problem.
You can only remove all manually installed python modules and reinstall the ilorest module with.
pip3 install python-ilorest-library
After this you should see inside “~/local/lib/python3/” a folder structure like this.
rwxrwx--- 3 SITE SITE 4096 Aug 18 19:42 ply/
drwxrwx--- 2 SITE SITE 4096 Aug 18 19:42 ply-3.11.dist-info/
drwxrwx--- 2 SITE SITE 4096 Aug 18 19:42 python_ilorest_library-3.2.2-py3.8.egg-info/
drwxrwx--- 6 SITE SITE 4096 Aug 18 19:42 redfish/
drwxrwx--- 2 SITE SITE 4096 Aug 18 19:42 six-1.16.0.dist-info/
-rw-rw---- 1 SITE SITE 34549 Aug 18 19:42 six.py
and inside the redfish folder you must have.
-rw-rw---- 1 SITE SITE 530 Aug 18 19:42 __init__.py
drwxrwx--- 2 SITE SITE 4096 Aug 18 19:42 __pycache__/
drwxrwx--- 3 SITE SITE 4096 Aug 18 19:42 hpilo/
drwxrwx--- 3 SITE SITE 4096 Aug 18 19:42 rest/
drwxrwx--- 3 SITE SITE 4096 Aug 18 19:42 ris/
If this is the case then the import must work.
Thank you so much for help.
Yeah, there were needed to uninstall python-ilorest-library module after uninstalling “redfish” module and than after new python-ilorest-library module install, content of redfish folder was corrected.
What is the advantage of using this special agent instead of SNMP?
SNMP is marked as obsolete from all big server manufacturers. The Redfish API is the actual standard for out of bound management for server systems. It is supported from all the relevant players in the market.
I also made a redfish special agent for Lenovo xClarity, Fujitsu and Dell. If i take a look at the output then and how to get this output then all the different systems are nearly identical. The data is complete structured and has not the many limitations of SNMP data (no floating point, no visible dependencies between data values).
Hi
I installed your HPE Ilo extension on a 2.0.0p19 (CFE) and also installed all the needed python lib’s (redfish and python-ilorest-library) but I can’t get any information from my ILO.
Then I tried to run the check manually with:
/omd/sites/main/local/share/check_mk/agents/special/agent_ilo --u USER-p PASSWORD IP
And yes, I replaced USER, PASSWORD, and IP with the needed info’s 
The only information I get back is:
Traceback (most recent call last):
File "/omd/sites/main/local/share/check_mk/agents/special/agent_ilo", line 25, in <module>
import cmk.utils.password_store
ModuleNotFoundError: No module named 'cmk'
type or paste code here
Maybe you can help me with the issue.
Best regards
Roberto
Have you run this as siteuser or as root?
Attention inside the package notes is written that you should only install the Redfish lib with “pip3 install redfish”. The “python-ilorest-library” is not used anymore and it leads to problems.
Actual package version is 3.4 from here. This version needs to be uploaded to the exchange as i have changed it the last week.
Hi tosch,
I tried as root and as a site user with the same issue.
Hi Andreas
I have downloaded your package from GIT. There I only found the version hpe_ilo-3.4.mkp. Is there any other version in your repository?
I have seen as the exchange version is a 3.3 Checkmk Exchange
3.4 is correct^^
But there you cannot install the “python-ilorest-library” the agent will not work with this one.
su siteuser
cmk -P install hpe_ilo-3.4.mkp
pip3 install redfish
~/local/share/check_mk/agents/special/agent_ilo
Hi again
Thanks for the hint. in between, I removed the package and it’s working as expected. 
GREAT work 
and thanks for your quick help.
Hi andreas-doehler,
I tried to use your agent on our iLO5 hosts, but I’m unable to get the check working.
I’ve installed your latest version 3.4 and redfish in version 3.1.6.
When I run the check on commandline, I get the following error:
Traceback (most recent call last):
File "/omd/sites/intel/local/share/check_mk/agents/special/agent_ilo", line 337, in <module>
REDFISHOBJ = redfish.redfish_client(base_url=iLO_host, username=iLO_account,
AttributeError: module 'redfish' has no attribute 'redfish_client'
What am I missing?
I tested at my system and had no problem. You are sure that it is only the Python module “redfish” installed? Not the old “python-ilorest-library” one.
The test on the command line was done as site user or?
I can do on the command line as site user the following.
python3
import redfish
redfish.redfish_client()
This gives the error message
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/omd/sites/cmk/local/lib/python3/redfish/rest/v1.py", line 1093, in redfish_client
if "://" not in base_url:
TypeError: argument of type 'NoneType' is not iterable
There you see the library is there and the attribute “redfish_client” is also existing.
this is what I get:

the system was freshly installed (Ubuntu 20.04), python-ilorest-library is not installed.
I don’t think so. This error only happens if python-ilorest-library is installed.

Here is the problem - these are Python2 modules and not Python3.
Please don’t mix pip and pip3
The only important folder is “~/local/lib/python3/”.
Thank you! You are right, the library was installed and showed with pip3 list.
After pip3 uninstall everything works as expected. Thanks again for your quick support!
