What Information Is Displayed in the Index Log?

The Index page displays detailed information concerning each indexing action (documents filtered, files not found, etc.). It is used to identify indexing errors and make sure all the repositories have been properly rebuilt or refreshed.

Example: It is possible to identify the complete path and filename of documents that have been rejected during indexing.

The Index page is made of two sections:

  • The Filters section allows to choose what information is displayed in the logs.

  • The Logs section displays the events in ascending or descending order.

Note: Before creating logs, it is preferable to adapt the log settings that determine the level of detail registered for each log and the time period during which logs are kept. By default, they are deleted after 90 days (see Modifying the Log Settings).


Filter Description


Displays the events that have occurred in a fixed time period (the last hour, 6 hours, week, etc.) or custom time period (delimited by two dates).

Log Fields

Displays 14 types of information concerning each event:

Severity: The severity of an event ranges from normal to critical. Normal events occur as part of the Coveo processes; whereas, critical events indicate errors likely to cause a system failure. The NORMAL status is attributed to all indexing processes; whereas, pages and documents not found are attributed a WARNING. For more information concerning severity types, refer to the Severity section below.

Time: The time (in hours, minutes, seconds) at which the indexing action was started.

Duration: The number of seconds CES took to crawl and convert (or reject) the document.

Description: Information allowing to identify the indexing action.

Address: The path of the document subjected to indexing.

Indexing operation: The action taken on the document (ex.: Updated, Not Found, Filtered). For more information concerning operations, refer to the Index Operations filter section below.

Collection: The collection (i.e. group of repositories) of the document (even rejected documents are attributed a collection).


Language: The languages identified by CES for the document (see Supported Languages).

Format: The file type of the document (see Supported File Formats).

Size: The size, in bytes, of the document file.

Note: The size of the document in the index is usually inferior to the size of the document file because CES regroups data to save index space.

Source: The repository of the document (even rejected documents are attributed a source).

Status: Whether the indexing process was successful (a failure indicates a problem connecting to the repository or a system error).

Links: The number of links encountered by the connector in the document.

Broken link: The number of broken links encountered by the connector in the document.


Displays 4 types of information for each event:

Details: Precise information about normal events.

Information: Generic information about normal events. This category is divided in two subcategories: IMPORTANT and NORMAL. Documents Added, Updated, Filtered and Deleted are attributed NORMAL severity. IMPORTANT severity identifies essential system processes (ex.: starting the Coveo instance), thus it is not used for indexing actions.

Warning: Information about non-critical abnormal event. Files Not Found are attributed a WARNING.

Error: Information about critical abnormal events. Critical abnormal events are likely to cause system failures.

Note: By default, details are not displayed because they are not useful for troubleshooting (they describe events not essential to the system functioning) and because they create longer logs.

Collection and Source

Displays the logs for the entire index or for a specific collection or source.

Index Operations

Determines which operations are displayed in the logs.

There are 10 operations:

Added: The document was added to the index for the first time (documents previously indexed are identified as Updated even during a rebuild).

Deleted: The document is removed from the index.

Updated: A more recent version of the document is indexed.

Unchanged: During the refresh, the document is not updated because it has not been modified since the last indexing. (During a rebuild, the document is updated).

Filtered by document type: The document is not indexed or removed from the index because the action for its document type is Reject document.

Unauthorized: The connector does not have sufficient permissions to open the document—thus, it is not indexed.

Not found: The Web page on which the document is located was not found.

Filtered by source filters: The document is not indexed or removed from the index by an exclusion filter.

Filtered by robot exclusion rules: The connector could not index the Web page because of a robot exclusion rule (i.e. tags indicating that a site must not be crawled).

No operation: No operation is attempted on the document.
