About the DataInsightWatchdog service
The DataInsightWatchdog service monitors the disk usage on the Windows File Server agent node and prevents it from running out of disk space by implementing safeguards. When the disk usage crosses the configured threshold, the DataInsightWatchdog service initiates the following safeguards:
Ensures that the Communication service stops all activities that generate data that can be reconstructed. For example, scanning.
Deletes all scan snapshot files, files in the
scanner/errfolder, and the volume usage database files in the
outboxfolder. Deleting these files creates additional disk space so that event monitoring can continue.
If the threshold is crossed again, and there is no other data that can be deleted, the DataInsightWatchdog service stops the DataInsightWinnas service, which in turn stops all event monitoring.
If the size of the
<DATADIR>/datafolder continues to grow, the DataInsightWatchdog service completely stops the Communication service.
The safeguard mode is reset once the disk space is available over the specified threshold. The DataInsightWinnas service and the Communication service, if stopped, is started, and scanning resumes normally.
When the Windows File Server agent is in the safeguard mode, its status appears as Failed on the Data Insight servers listing page on the Management Console.
In addition to enforcing safeguards on the Windows File Server nodes, the DataInsightWatchdog service also runs on each Data Insight server. The service monitors the CPU, disk, and memory on each node. If CPU, disk, and memory are consistently high for a server, the service sends out notifications to configured email recipients.
The node safeguard feature is enabled by default with specific default values. You can configure the thresholds for initiating the safeguard mode from the Settings > Global Settings > Scanning and Event Monitoring page of the Management Console.
For more information about configuring the threshold values for initiating the safeguard mode, see the Data Insight Administrator's Guide.
