vRealize Orchestrator control center : HTTP Status 500 Failed to edit Log insight configuration file

With latest vRealize Orchestrator 7.0.1 I was configuring syslog logging integration in control center, to send logs to vRealize Log insight, but ran into error "HTTP Status 500 Failed to edit Log insight configuration file".


Troubleshooting:

Testing on a fresh install and did no run into the problem so came to the conclusion that this error only appears when you upgrade from 7.0 to 7.0.1

SSH into Orchestrator appliance and reviewed the logs.
/etc/var/log/messages

Found the script that gets executed to be /var/lib/vco/configuration/bin/config_liagent.sh which actually resides on /usr/lib/vco/configuration/bin/config_liagent.sh

Listing the folder shows that vco:vco has rwx permission.

:/usr/lib/vco/configuration/bin # ls -ll

-rwx------ 1 vco vco  218 Feb 19 15:09 config_liagent.sh

-rwx------ 1 vco vco  230 Feb 19 15:09 controlcenter.sh

-rw-r--r-- 1 vco vco 6718 Feb 19 15:09 log4j.dtd

-rw-r--r-- 1 vco vco 3315 Feb 19 15:09 propagate.sh

-rwx------ 1 vco vco 1321 Feb 19 15:09 setenv.sh

A password is required is throw in the error message which leads me to think the vco user does not have the necessary permissions when trying to execute the command.

Looking in /etc/sudoers file and found the vco missing the path to the config_liagent.sh file.

Resolution:

Add the path to config_liagent.sh for vco user.

# visudo

scroll to bottom of file.

you will see the following:

vco     ALL=(root) NOPASSWD: /etc/init.d/vco-server, /etc/init.d/vco-configurator

update the line as follows:

vco     ALL=(root) NOPASSWD: /etc/init.d/vco-server, /etc/init.d/vco-configurator, /var/lib/vco/configuration/bin/config_liagent.sh
