NetScaler MAS allows you to view and download the configuration audit diff report in configuration audit section. The configuration audit section enables you to export the summary report across all instances and per instance, and also allows you to export granular diff report for each instance-template pair.
The audit templates that appear in the Audit Templates list are run at the scheduled time against the configurations in the specified instances. The NetScaler Config Drift chart on the Configuration Audit dashboard displays high-level details about configuration changes in saved against unsaved configurations. When you click NetScaler Config Drift chart, the ensuing Audit Reports page displays a list of instances that shows both "Diff Exists" and No Diff." You can download the diff reports displayed by NetScaler MAS.
NetScaler MAS also provides an option to schedule automatic export of diff report as a mail attachment. For more information on how to schedule export of reports, see Creating Audit Templates.
To export configuration audit reports
1. In NetScaler MAS, navigate to Networks > Configuration Audit.
2. On the Configuration Audit page, click inside the NetScaler Config Drift chart.
3. The Audit Reports page lists instances that have a difference. The page also displays a list of instances that does not have any difference in their running configurations.
In the image you can see that for some instances a diff is present only in Saved Vs Running Diff and for some instances, a diff is present only in Template vs Running Diff. For some instances, differences exist in both Saved Vs Running Diff and Template vs Running Diff.
Saved Vs Running Diff
You can view a report of the diff between the configuration saved on the instance and the configuration currently running on that instance. For example, click Diff Exists for an instance under Saved Vs Running Diff.
Here, you can see a report for saved configuration against running configuration diff for that instance.
Click Export diff report to download a .csv file of the diff report. You can also click Export corrective commands to export the commands to a .txt file. You can then run the commands on the associated NetScaler instance from configuration jobs to correct the configuration in that instance.
Template vs Running Diff
The Template vs Running Diff includes all templates other than Saved Vs Running Diff which is the default template. You can view the difference that exists between the template and running configuration. For example, click Diff Exists for one of the instances under Template vs Running Diff.
Now you can see that two templates show diff and the NetScaler instance has a different configuration from what the template is looking for.
Click Diff Exists again. The following image shows the configuration that the template is looking for and the running configuration that is blank, because no such commands has been configured or has been removed. You can also see the correction configurations or the commands to run to correct the configuration.
Click Export diff report to download a .csv file of the diff report. You can also click Export corrective commands to export the commands to a .txt file. You can then run the commands in CLI to correct the configuration in that instance.
The following image shows an example .csv diff file that is downloaded to your system:
