Configuring scanning and event monitoring

You can configure Data Insight to globally turn on or off receipt of event notifications and safeguards related to FPolicy communication.

Data Insight allows you to disable scanning of all file systems. The scans can be enabled at any convenient time.

You can also configure whether you want the Scanner to fetch the Access Control Lists (ACLs) defined on folders and ownership information for files and folders. For Windows File Servers, you can configure safeguards that prevent an agent from taking up too much disk space.

To configure scanning and event monitoring

  1. In the Management Console, click Settings > Scanning and Event Monitoring.

    You can view the state of scanning and event monitoring.

  2. To change the state of a process to Enabled or Disabled, click Edit.
  3. Do one of the following:
    • Select the check box for the process that you want to enable.

    • Clear the check box for the process that you want to disable.

  4. Click Save to save the changes.

Table: Scanning and Event Monitoring options

Option

Description

Scan File System meta-data

Clear the check box to turn off all future file system scanning on all filers. Once you save the setting, it will also stop all currently running scans.

Get Folder ACLs

Clear the check box if you do not want Scanner to fetch Access Control List (ACLs) for folders during scanning.

If you disable this option, the Workspace > Permissions tab in the Console is disabled and permission related reports will not produce any data. If you do not need permissions data, you can disable this option to make the scans run faster.

Get Ownership information for files and folders

Clear the check box if you do not want Scanner to fetch the Owner attribute for files and folders.

Ownership information is used to determine ownership for data when access events are not available. If you do not need this information, you can disable this option to make scans run faster.

Throttling for NetApp filers

Select Throttle scanning based on latency of the filer to enable throttling of Data Insight scans for NetApp 7-mode and Cluster-Mode file servers. This option is not selected by default.

Data Insight collects latency information from NetApp file servers. It can use this information to throttle scanning, if latency of the file server increases above a certain level. This ensures scanner does not put additional load on the file server during peak load conditions.

You can configure the following parameters to enable throttling for NetApp file servers:

  • Latency threshold - Specify latency in milliseconds, which when crossed, should throttle scanning for the file server.

  • Minimum pause - Specify the minimum duration (in milliseconds) for which the scanner should pause between paths when in throttling mode.

  • Back off value - If increased latency is sustained, pause interval will be increased by the Back off value specified (in milliseconds).

  • Maximum pause - Specify the maximum pause interval for the scanner (in milliseconds). If exceeded, pause interval is no longer incremented by Back off value.

Monitor file system access events

Clear the check box to stop Data Insight from collecting access events from all file servers. In case of NetApp, it means all collector nodes will disconnect their Fpolicy connections to file servers.

Disk Safeguard settings for Windows File Server agents

Select Enable node safeguard check box to monitor the disk usage on the Windows File Server node, and prevent it from running out of disk space by implementing safeguards.

You can specify the threshold for disk utilization in terms of percentage and size. The DataInsightWatchdog service initiates the safeguard mode for the Windows File Server node if the free disk space falls under the configured thresholds.

The DataInsightWatchdog service automatically resets the safeguard mode when the free disk space is more than the configured thresholds.

You can edit the threshold limits as required. If you specify values in terms of both percentage and size, then the condition that is fulfilled first is applied to initiate the safeguard mode.

For more information on the DataInsightWatchdog service, see the Veritas Data Insight Installation Guide.

Fpolicy Safeguard settings

Select the following:

  • Enable FPolicy 7-Mode Safeguard to initiate safeguard mode for the NetApp file servers.

  • Select Enable FPolicy 7-Mode safeguard for VFilers to initiate safeguard mode for virtual file servers by monitoring latency statistics for the associated physical NetApp filers.

    The safeguard mode for the virtual filers is initiated only if the details of the physical filer corresponding to the virtual filer are provided while adding the virtual filer.

  • Select Enable FPolicy Cluster Mode Safeguard to initiate safeguard mode for the NetApp cluster mode file servers.

This Fpolicy Safeguard settings are not selected by default.

Data Insight collects latency information from NetApp file servers. It can use this information to initiate safeguard mode, if latency of the file server increases above or falls below a certain level. When the safeguard is in effect, Data Insight drops its Fpolicy connection to the filer. This ensures event collection does not put additional load on the file server in peak load conditions.

If the latency (CIFS or NFS) on the physical file server increases above the configured threshold, Data Insight disconnects from the associated virtual file server even if monitoring for that type (CIFS/NFS) was not enabled on the virtual filer. This information is also displayed on the Data Insight System Overview dashboard.

Configure the following values:

  • The high and low thresholds for CIFS and NFS.

  • The number of samples to be considered to calculate the average latency.

  • The minimum time to wait before Data Insight reconnects to the filer after a disconnection.

See Add/Edit NetApp filer options.

You can choose to override the global scan throttling and FPolicy safeguard settings for specific Collector nodes.

See Configuring advanced settings.
