About diagnostic tracing

Diagnostic tracing is used to capture detailed information about error conditions. Quest Technical Support personnel use this information for debugging and troubleshooting purposes.

Tracing is disabled by default. To capture diagnostic information, you must enable tracing on the relevant NetVault machines. You can configure NetVault to start tracing immediately or when the service restarts. You can also specify a time window to automatically start and stop tracing at the specified time.

 
* 
IMPORTANT: Diagnostic trace settings should only be configured under the direction of Quest Technical Support.

Diagnostic information is written to trace files. You can generate trace files for all processes or a subset of processes. These files are generated on the machine where the selected processes are running. NetVault uses a Trace Container directory to store all trace files generated during various sessions. By default, the trace container directory is created under the NetVault installation directory. You can modify the default settings to specify a new location for the container directory. When tracing is enabled, a session directory is created under the container directory; all trace files generated during the session reside in this directory. You can use the WebUI to download trace files from various machines to the local machine where the WebUI is running.

MSP administrator can enable and disable tracing and tracing filters on NetVault Server and its own client machines. Whereas, tenant administrator can enable and disable tracing filter only for its own client machines.

When tracing requires diagnostic information on NetVault Server and tenant client machines, MSP administrator and tenant administrator must sync with each other to enable and disable tracing for a particular operation during a given time window.

After generating and downloading traces, tenant administrator provides traces to MSP administrator to send for further analysis or investigation.

Managing trace filters

NetVault 11.2 or later allows you to manage trace filters to NetVault processes (core and plug-in) from the NetVault WebUI. You can change/ assign trace settings for these processes using the option Manage Trace Filters.

To manage trace filters:
1
In the Navigation pane, click Change Settings.
2
To manage trace filters:
•
For the NetVault Server: On the NetVault Server Settings page, under System and Security, click Diagnostic Tracing.
•
For the NetVault Client: On the NetVault Server Settings page, click Clients. In the NetVault Clients table, select the client, and click Next. Under System and Security, click Diagnostic Tracing.
3
In the Diagnostic Trace Settings page, click Manage Trace Filters.
4
In the list of NetVault (core and plug-in) processes, select the process to edit. Click Edit.
5
In the Edit Trace Filter Mapping dialog box, configure the following settings:
 
Table 156. Edit Trace Filter Mapping
Setting
Description

Selected Process

Selected NetVault process (core and plug-in) is displayed.

Filter

Click the down arrow and select any of the following filter options:

•
KillAll: When this filter is assigned to a process, the process will not generate any traces.
•
MessageOnly: If this filter is assigned to a process that process will only produce trace messages from MESSAGE module. All other trace messages will be filtered out.

Specify the following trace filter mapping options for the selected process:

•
Enable Filter: Select this option to enable the selected filter option for the selected process.
•
Force Disk Tracing: Select this option to allow the selected process to trace the disk (even when disk tracing is disabled).
•
Circular: Select this option to enable circular tracing and type or select the values in the following fields:
•
Lines per trace file: Number of lines per trace file when circular is enabled. When lines in a trace file exceed this threshold, traces are written to next trace file.
•
Number of trace files to keep: Number of trace files to keep when circular is enabled. When number of trace files exceed this threshold, oldest trace file will be overwritten.

Click Update to apply the new settings and close the dialog box.

Enabling tracing

Diagnostic tracing is disabled by default. When investigating a problem, Quest Technical Support might ask you to enable tracing on the relevant NetVault machines to capture diagnostic information about the error condition. This information helps in determining the source of error condition. Once the traces are enabled for the server, warning is displayed as Diagnostics in the Header Pane of NetVault.

 
* 
IMPORTANT: Tracing can affect performance of the application and generate large amounts of data on the server and client machines. You should only enable tracing when requested by Quest Technical Support, and disable this option after the issue is resolved.
To enable diagnostic tracing:
1
In the Navigation pane, click Change Settings.
—or—
In the Navigation pane, click Manage Clients.
