authentication. The Device SGT diagnostic tool connects to the network device whose IP address you provide and does 
the following:
1.Obtains the network device’s SGT value.

Configuration in the Monitoring and Report 
Viewer
This chapter describes the tasks that you must perform to configure and administer the Monitoring and Report Viewer. 
The Monitoring Configuration drawer allows you to:
Manage data—The Monitoring and Report Viewer handles large volumes of data from ACS servers. Over a period of 
time, the performance and efficiency of the Monitoring and Report Viewer depends on how well you manage the...

Configure collection filters—The Monitoring and Report Viewer provides you the option to filter data that is not used 
for monitoring or troubleshooting purposes. The data that is filtered is not stored in the database and hence saves 
much needed disk space. See Understanding Collection Filters, page 17 for more information on how to configure 
collection filters.
Configure system alarms—System alarms notify you of...

Configuring Data Purging and Incremental Backup
Configuring Data Purging and Incremental Backup
The Monitoring and Report Viewer database handles large volumes of data. When the database size becomes too large, 
it slows down all the processes. You do not need all the data all the time. Therefore, to efficiently manage data and to

Configuring Data Purging and Incremental Backup
—If the backup fails and the database disk usage is greater than 60 percent of the allocated view database size, 
the Monitoring and Report Viewer decides to wait. 
For example: 
• If you specify that you want to preserve one month of data, and the database size is greater than 100 percent of 
the allocated view database size within a month, the purge deletes the data on a...

Configuring Data Purging and Incremental Backup
—If the log recovery feature is not enabled and the ACS view database compress option is enabled, an automatic 
database compress operation is triggered only after enabling the log recovery feature when the size of the 
database exceeds 80 percent of allocated view database size to avoid disk space issues. 
—If the log recovery feature and the ACS view database compress...

Configuring Data Purging and Incremental Backup
Configuring NFS Staging
If the utilization of /opt exceeds 30 percent, then you are required to use NFS staging with a remote repository to take 
successful view database backups and generate support bundles. NFS staging uses a Network File System (NFS) share 
as a staging area of additional disk space during a backup or support bundle request, because these operations are...

Restoring Data from a Backup
Restoring Data from a Backup
Use this page to restore data from the View database that was backed up earlier. You can restore data from an 
incremental or full backup. If you choose to restore incremental backup data, ACS restores the full View data backup and 
then the rest of the incremental backups one at a time in the correct sequence.
Note: You must restore the incremental and full view...
