The ServiceNow perl script is suppose to log the connections to the following log file. Check it for any errors and make sure the URL it is trying to access is correct.

I have updated same error msg in /var/log/sn_ticketer.log and accessing the correct url

The error on line 301 is when the perl script is trying to connect to the Service Now site and the URL data is not formatted correctly.
The data in the URL is formatted by the field_map.ini file so make sure that is setup.

Here are some instructions on setting up the mapings.

Optionally you can use the default field_map.ini settings but in the likely case you need to customize it do one of the following:

If you are familiar with the service-now page field formats then read the Field mapping section below, then open the field_map.ini and begin mapping. OR 9a. If you are NOT familiar with the service-now page field formats then create a backup copy of field_map.ini 9b. Open field_map.ini and remove all the default [incident.do] configuration settings, save and exit. 9c. Run the map builder: ./sn_ticketer.pl --page='incident.do' --buildmap 9d. Open the field_map.ini, if everything went well it should now contain all of the available fields for creating incidents. 9e. Remove all of the fields you don't need and read the Field mapping section below to learn more about configuration.

You should go through the README.md file in the folder where the perl script resides for more details on the field_map.ini file.

If you have to go through a proxy server to access the internet, make sure that is setup in the config.ini.

When i perform the default incident.do using script getting same error Bad request

[root@ libexec]# ./sn_ticketer.pl --page='incident.do' --buildmap

When mention the [incident.do] in field_map.ini, then getting below error msg

[root@ libexec]# ./sn_ticketer.pl --page="incident.do" --buildmap

Page mapping already exists in field map config, stopping import.

where i can see the mapping imported mapping fields ?

Please attach this file:
Please PM me a copy of your profile, you can download it from Admin > System Profile by clicking the Download Profile button.

Thank you!

I have attached the script

Thank you

Raghavendra

That's the latest so you should be fine.

Please attach (or PM) your /usr/local/nagios/libexec/config.ini. You can sanitize the user/password but leave any special characters in them that you have in them so I can see if those have issues.

I have shared the config file

Check your PMs, I just sent a reply, I think it has to do with special characters in the password with a basic auth URL:
