I have installed the technical add-on for tenable on my search head and it was working until a few days ago. For a few days I always going to get the following error message:
Unable to initialize modular input "tenable_securitycenter_mobile" defined in the app "TA-tenable": Introspecting scheme=tenable_securitycenter_mobile: script running failed (exited with code 1)..
Does anyone know what it means?
Thank you very much for helping me!
Had the same issue.
The problem is with a TA-tenable app and with "ModuleNotFoundError: No module named 'urllib2'"
urllib2 is no longer supported.
Fixed this issue:
1) delete TA-tenable directory from apps directory on all search nodes
2) install a new version of this app from https://splunkbase.splunk.com/app/4060/
3) restart splunk
Just app reinstall without manual deleting will not help.
