Configuring disk space alert thresholds

The Logging Daemon performs periodic disk space checks, and issues alert messages when the space usage level reaches the Warning or Critical Threshold. These checks are performed for the following directories: NetVault Backup Home, Database, Logs, and Reports directories.The Warning and Critical thresholds are set to 85 and 95 percent of the total disk space, respectively. The default interval between two disk space check events is one hour.

You can use the configuration settings for Logging Daemon to change the alert thresholds and default interval for disk space checks.

 
* 
NOTE: You must restart the NetVault Backup Service to apply any changes to the Warning and Critical Threshold values.
To change the default alert threshold settings:
1
In the Navigation pane, click Change Settings.
2
On the NetVault Server Settings page, under Services, click Logging Daemon. In the Logging Daemon dialog box, configure the following settings.
 
Table 134. Disk space alert threshold settings
Setting
Description

Disk Space Warning Threshold

Type or select the Warning Threshold level. The default value is 85 percent of the total disk space.

When the disk space usage reaches or exceeds the Warning Threshold, the following events occur:

•
The Logging Daemon reports an error.
•
The Auditor Daemon logs a message.
NetVault Backup raises the Home Drive Becoming Full event.

Disk Space Critical Threshold

Type or select the Critical Threshold level. The default value is 95 percent of the total disk space.

When the disk space usage reaches or exceeds the Critical Threshold, the following events occur:

•
NetVault Backup sends an error message to the Event Viewer on Window and syslog on Linux and UNIX.
•
The Logging Daemon reports an error.
NOTE: If the disk space is critically low when the NetVault Backup Service starts, the errors are only logged through the Event Viewer or syslog.
•
The NetVault Backup Service shuts down automatically and the service status is set to “Stopped Disk Full.”
You can restart the service only when the disk usage percentage drops below the configured Critical Threshold level.

Time interval between disk space full checks

Type or select the interval between two disk space check events. It is specified in number of hours. The default value is one hour.

To disable disk space checks, set the value to zero (0).

NOTE: Regardless of this setting, the Logging Daemon performs disk space check when the NetVault Backup Service is restarted.

Modifying the purge policy for log messages

Log messages that are older than 30 days are automatically purged from the database. You can use the configuration settings for Logging Daemon to change the maximum age for log messages.

 
* 
NOTE: You can also manually delete the log messages by using the Purge Logs method available on the View Logs page. For more information, see Manually purging the log messages.
To modify the purge policy for logs:
1
In the Navigation pane, click Change Settings.
2
On the NetVault Server Settings page, under Services, click Logging Daemon. In the Logging Daemon dialog box, configure the following settings.
 
Table 135. Auto-purge settings for logs
Setting
Description

Auto-purge method

By default, the Auto-purge method is set to “Exceeds log age.” Use this setting to delete logs that are older than a specified number of days.

To disable automatic purging of log files, set the Auto-purge method to “None.”

NOTE: Log messages can consume a considerable amount of disk space. Therefore, periodic purging of the log messages is necessary. If automatic purging is disabled, use the Purge method available on the View Logs page to manually delete the log messages at regular intervals.

Auto-purge entries that are older than

When the Auto-purge method is set to “Exceeds log age,” use this setting to specify the maximum age for logs. The log age is specified in number of days. The default value is 30 days.

Select the time interval to auto-purge

The default interval between two auto-purge events is three hours. To change the interval, type or select a new value. The purge interval is specified in number of hours.

Configuring additional settings for Logging Daemon

To configure additional settings for the Logging Daemon:
1
In the Navigation pane, click Change Settings.
2
On the NetVault Server Settings page, under Services, click Logging Daemon. In the Logging Daemon dialog box, configure the following settings.
 
Table 136. Additional settings for Logging Daemon
Setting
Description

Message Response Interval

This setting determines the amount of time the NetVault Backup WebUI waits for the Logging Daemon to send all log messages before displaying a progress dialog box. The dialog box displays the number of log messages loaded against the total number of log messages. If the response is delayed, you can cancel the operation by clicking Cancel on the progress dialog box.

The default response time for the Logging Daemon is 256 milliseconds. To change default setting, type or select a new value. The minimum value can be 100 milliseconds.

If the NetVault Backup WebUI receives all log messages within the specified interval, the progress dialog box is not displayed (for example, if there are only a few log messages, the dialog box is not displayed).

Outgoing message bundle size

To improve performance, the logging daemon sends messages in bundles. Each bundle contains 64 messages by default. To change the number of messages per bundle, type or select the bundle size in Outgoing Message Bundle Size.

Minimum time between progress updates

By default, the progress dialog box is refreshed every 256 milliseconds. To change the refresh rate, type or select the time interval.

Minimum warning level to send to system log

By default, NetVault Backups sends log messages with warning code 64 and above to the OS. You can view these messages from the Event Viewer (on Windows) or syslog (on Linux and UNIX).

To change the severity level of messages that NetVault Backup sends to the OS, specify the warning level code in the Minimum warning level to send to system log box. The following list provides the warning codes and the corresponding severity level of the messages:

•
112: Severe errors
•
96: Severe errors and errors
•
80: Severe errors, errors and warnings
•
64: Severe errors, errors, warnings, and startup messages
•
48: Severe errors, errors, warnings, startup messages, and job messages
•
32: Severe errors, errors, warnings, startup messages, job messages, and informational messages
•
16: Severe errors, errors, warnings, startup messages, job messages, informational messages, and background messages
•
0: All messages
