Does ServiceNow has the capability to discovery CentOS Operating system

[RajeshGummadoju]

Hi All,

Does ServiceNow has the capability to discover CentOS operating system(Guest OS:CentOS 6(64bit)), when I see docs it is supported but I didn't find CentOS choice value in Operating System field.

These types of Linux OS's are supported:

• Red Hat
• Fedora
• Debian
• SUSE
• CentOS
• Ubuntu

Any information would be highly appreciated.

Thanks in Advance,

Best Regards,

Rajesh

As you say, it looks as though it is supported based on the docs, but I can see in my demo instances that the value does not look to exist by default for me also.

That should not prevent discovery from populating the correct value in the field, but you may need to update the choice list to inlcude the 'CentOS' value if you want to be able to manually populate the OS on a CI

Operating System field in the Server CI Class is of string type, not choice list so if you run Discovery against the CentOS system it will update this field with the OS in question.

Yes, Operating System is a string field, which is cloned to child classes from cmdb_ci_computer.os. If you look at the dictionary entry for cmdb_ci_compuer.os, there is a choice list configured in there - it looks as though there are 35 options OOTB in San Diego.

When a discovery payload has a value that is not contained in the choice list, it will still populate the value and generally it will appear in blue text when you view the record, to indicate that the value is not contained in the relevant choice list.

BTW, if you do decide to add the additional value to the choice list, be sure to follow ServiceNow's lead and add it at the cmdb_ci_computer.os level rather than creating a new value on just the Linux class, as I have seen others do in the past. Much easier to maintain if they are all in the same place.

Hi Rajesh,

Yes of course it has the capability and it shows under the OS field. You can check below screenshots, I have numerous machines discovered.
