What Information Is Displayed in the System Log?

The System page displays all events (including querying and indexing actions) that have occurred in the Coveo Platform during the specified time period. It is used to identify global errors and make sure the processes requested (ex.: source refresh, connection to a mirror server) have actually occurred.

The System 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 four types of information for each event:

Severity: The severity of an event ranges from normal to critical. Normal events occur as part of CES processes; whereas, critical events indicate errors likely to cause a system failure. For more information concerning severity types, refer to the Severity filter section below.

Time: The time (in hours, minutes, seconds) at which the event occurred.

Duration: The number of seconds elapsed between the beginning and end of the event.

Description: Information allowing to identify an event and the processes it is related to.


Displays four 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. System processes essential to CES functioning (ex.: starting the Coveo instance) are attributed IMPORTANT severity; whereas, non-essential processes (ex.: loading a source, enabling queries) are attributed NORMAL severity.

Warning: Information about non-critical abnormal events. Non-critical events do not cause system failures.

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 create much longer logs.
