What Is File Monitoring and Live Indexing?

File monitoring and live indexing are processes which keep documents up-to-date without requiring constant source refreshes or rebuilds. File monitoring applies to Local/Network Files sources located on Windows servers. Live indexing applies to other source types such as SharePoint and Exchange sources. Many additional connectors support live indexing.

The difference between file monitoring and live indexing is that file monitoring registers Windows file system events and re-indexes documents as soon as they are modified, while live indexing scans the repositories and re-indexes modified documents at short intervals (ex.: 300 seconds). By default, file monitoring and live indexing are enabled. You can however disable them to save CPU resources and speed up CES.

To disable file monitoring or live indexing

  1. On the Coveo server, access the Administration Tool (see Opening the Administration Tool).

  2. Access the Sources and Collections page (Index > Sources and Collections).

  3. In the Sources section, click the appropriate source. The Status page is displayed.

  4. Click Disable File Monitoring or Disable Live Indexing (to re-enable it, click Enable File Monitoring or Enable Live Indexing).

Note: Because file monitoring is dependent of events registered by the Windows file system, it is possible that some modifications are overlooked, especially when numerous events occur at the same time (file monitoring can handle approximately 4,000 events per minute). Therefore, it is recommended to keep a source refresh schedule (see How to Apply a Refresh Schedule to a Source).

Moreover, file monitoring cannot be enabled on a source whose address is a specific file (ex.: \\CoveoServer\HelpFiles\CESOnlineHelp.docx).
