Server Utilization Information
The Cisco Vision Director Server monitoring service (named Director Service OS) polls system status every 600 seconds for the CPU, memory (RAM), and storage utilization.
Utilization status is reported based on the server alert thresholds configured in the System Status (Figure 50).
The gauges in the Server Utilization panel in the Overview interface provide an at-a-glance view of the percentage of CPU, memory, and disk space usage for the Cisco Vision Director Server ( Figure 50).
Figure 50 Cisco Vision Director Server Utilization and DMP Summary
IMPORTANT: The System Status shows a critical alert when the CPU or Disk utilization goes above 90%, or if the Memory utilization goes above 95%. To find these thresholds, click Configuration > System Configuration > Management Dashboard > Server Alert Thresholds.
TIP: You can also find the current CPU, memory, and disk utilization percentages in the daily Vision Health Report, if configured.
Table 6 lists the server utilization information for each server profile.

Server Alert Thresholds
Utilization status and alerts are reported based on the server alert thresholds configured in the System Configuration.
Two alert thresholds are defined for CPU, free memory, and disk space:
■ Warning —Warning thresholds define the yellow area of the server utilization gauges.
■ Error —Error thresholds define the red area of the server utilization gauges and correspond to critical alerts.
To check the default values of server alert threholds:
1. Click Configuration > System Configuration > Management Dashboard > Server Alert Thresholds.
2. Select the Value from the Configuration Property panel.
3. Click Edit to make changes. The Edit - Configuration Setting dialog box appears.
4. Type in a new Value and click Save.
5. Click Refresh.
Figure 51 shows the default threshold values for the different system areas.
Figure 51 Default Values for Server Alert Thresholds
DMP Alert Thresholds
Utilization status and alerts are reported based on the DMP alert thresholds configured in the System Configuration.
To check the default values of DMP alert threholds:
1. Click Configuration > System Configuration > Management Dashboard > DMP Alert Thresholds.
2. Select the Value from the Configuration Property panel.
3. Click Edit to make changes. The Edit - Configuration Setting Dialog box appears.
4. Type in a new Value and click Save.
5. Click Refresh.
Figure 52 shows the default threshold values for the different system areas.

Memory Utilization
If memory utilization is above the 90% alarm threshold for over a long period of time, there could be something running in the system which is using more memory than it should.
Table 7 shows the total memory on a Cisco Vision Director server.
IMPORTANT: If memory utilization is above 90%, open a case with Cisco Technical Support.
Table 7 Memory Utilization and Threshold Values3.6 GHz
Disk Utilization
If disk utilization is above the threshold, the disk space is filling up. The disk might fill up from having a lot of backup files, proof-of-play files, or log files, in addition to your content.
Table 8 shows the total hard disk size and recommended minimum free space.
Table 8 Hard Disk Values
IMPORTANT : The Daily Backup task might consume the hard disk space limit, which can cause the system to fail in unexpected ways.
How to Manage Disk Utilization
This section includes the following topics:

■ Deleting System Files
Modifying File Retention Periods on the Cisco Vision Director Server
User Role: Installer (Administrator)
Cisco Vision Director allows you to define retention periods for backup and log files in the Text Utility Interface (TUI).
The default settings are:
■Backup files—One file. The backup retention policy can be modified to 2, 5, 7, or 10 files.
■Log files—15 days. The log retention policy can be modified to 5 or 10 days.
CAUTION : Track your overall disk utilization and the size of your backup content so the number of files that you want to keep can be supported by your system resources.
For more information about using the TUI, see the "Cisco Vision Director Text Utility Interface" module of the Cisco Vision Director Server Administration Guide.
To modify the file retention periods:
Note : The retention policy must be changed on both the primary and secondary servers.
1. Log into the TUI.
2. Go to Cisco Vision Server Administration > Retention Policy.
3. Select the Backup/restore Files menu or the Log Files menu and type the letter for the retention period.
Deleting System Files
User Role: Installer (Administrator)
You can use the TUI to remove the following types of system files:
■Log files
■System state reports
■ISO upgrade files
■Backup files
Running Database Maintenance
User Role: Installer (Administrator)
One way to see if you might need to run database maintenance is to look at the backup log (/var/log/svd-config/backup- YYYMMddHHMMSSz.log). If you see that the table updates are other than “OK” or not up-to-date, then run database maintenance.
Note : Slow performance is another possible sign that database maintenance is needed.
For more information about using the TUI, see the "Cisco Vision Director Text Utility Interface" module of the Cisco Vision Administration Guide: Dynamic Signage Director.
IMPORTANT: You must be sure to restart Cisco Vision Director software after maintenance is complete. The best practice is to shut down the Cisco Vision Director software before running database maintenance and then restart it after maintenance is complete. However, even if you did not shut down prior to running maintenance, you still must restart the Cisco Vision Director software.
To run database maintenance:
1. Log into the TUI.
2. (Recommended) Shut down the Cisco Vision Director software. From the Main Menu, go to: Cisco Vision Server Administration > Database Maintenance ( Figure 54).
Figure 54 TUI Database Maintenance Option
3. At the confirmation prompt, press Y to start the process ( Figure 55).
Figure 55 Database Maintenance Confirmation Prompt
4. As the maintenance runs, the status of each table updates.
5. When database maintenance is complete, restart the Cisco Vision Director software.
6. From the TUI Main Menu, go to: Cisco Vision Server Administration > Restart Dynamic Signage Director Software.
