If you have a command that outputs just what you want, this should be something you can script and save the output using the Archive command in your script.
For more info on this you can look in the included documentation under Configuration Management>Job Management side tab>Script Reference>CCS data archive and export (excerpt below)
CCS data archive and export
The CCS Data Archive / Export feature enables you to archive
and export any information available via the CLI. Data archiving is
accomplished using the ARCHIVE keyword. Archived data can then be
exported from NetMRI using HTTP.
The ARCHIVE keyword
The ARCHIVE keyword is supported in the
Action/Trigger-Commands sections of a CCS file and can be used to save
the output of various CLI commands into one or more files. The keyword
can be followed by an optional file name and should precede all commands
for which the output should be archived. For example:
Action-Commands:
ARCHIVE
(config.txt): show running-config
would store the output of the show running-config
command in the file config.txt.
Output from multiple commands can be stored in the same file,
for example:
Action-Commands:
ARCHIVE
(config.txt): show running-config
ARCHIVE (config.txt): show
startup-config
would store the output of the commands show
running-config and show startup-config in the file config.txt.
Variables can be used to specify the name of the file
dynamically, for example:
Action-Commands:
ARCHIVE
(config-$ipaddress.txt): show running-config
would store the output of the show running-config
command in the file config-10.10.10.1.txt, assuming the script was
currently running against the device 10.10.10.1.
At the end of a job, files created using the ARCHIVE
keyword are placed in a single .zip file. You can view the
files and download the .zip file in the Files tab in the Job Viewer.
It is important to dynamically specify file names. For
example, if a job runs against two devices and the script specifies a
static file name, both jobs would use the same file name. At the end of
the job, only one file would be contained in the .zip file
because of the file name collision (i.e., there is no directory
structure contained in the .zip file).
CCS Data Export
Besides being accessible through the Files tab in the Job
Viewer, the most recent archive .zip file is placed in a
global location where it can be accessed via an HTTP transaction.
Details on this transaction are as follows:
Request Info
URL: /netmri/ccs/tx/common/GetArchive.tdf
Parameters:
N/A
Response Info
Content-Type: application/zip
Content-Disposition:
NetMRI_CCS_Archive.zip
Content: The most recent ARCHIVE .zip file
Use this mechanism to export the most recent archive .zip
file to an external application or server on a scheduled basis using a
tool such as wget.
