Working with Logs in the Developer Console

Use the Logs tab in the Developer Console to open debug logs.

Use the Logs tab to open relevant debug logs for review

Logs open in Log Inspector. Log Inspector is a context-sensitive execution viewer in the Developer Console. It shows the source of an operation, what triggered the operation, and what occurred next. Use this tool to inspect debug logs that include database events, Apex processing, workflow, and validation logic.

To learn more about working with logs in the Developer Console, see Log Inspector in the Salesforce online help.

When using the Developer Console or monitoring a debug log, you can specify the level of information that gets included in the log.
Log category
The type of information logged, such as information from Apex or workflow rules.
Log level
The amount of information logged.
Event type
The combination of log category and log level that specify which events get logged. Each event can log additional information, such as the line and character number where the event started, fields associated with the event, and duration of the event.

Debug Log Categories

Each debug level includes a debug log level for each of the following log categories. The amount of information logged for each category depends on the log level.

Log Category Description
Database Includes information about database activity, including every data manipulation language (DML) statement or inline SOQL or SOSL query.
Workflow Includes information for workflow rules, flows, and processes, such as the rule name and the actions taken.
NBA Includes information about Einstein Next Best Action activity, including strategy execution details from Strategy Builder.
Validation Includes information about validation rules, such as the name of the rule and whether the rule evaluated true or false.
Callout Includes the request-response XML that the server is sending and receiving from an external web service. Useful when debugging issues related to using Lightning Platform web service API calls or troubleshooting user access to external objects via Salesforce Connect.
Apex Code Includes information about Apex code. Can include information such as log messages generated by DML statements, inline SOQL or SOSL queries, the start and completion of any triggers, and the start and completion of any test method.
Apex Profiling Includes cumulative profiling information, such as the limits for your namespace and the number of emails sent.
Visualforce Includes information about Visualforce events, including serialization and deserialization of the view state or the evaluation of a formula field in a Visualforce page.
System Includes information about calls to all system methods such as the System.debug method.

Debug Log Levels

Each debug level includes one of the following log levels for each log category. The levels are listed from lowest to highest. Specific events are logged based on the combination of category and levels. Most events start being logged at the INFO level. The level is cumulative, that is, if you select FINE, the log also includes all events logged at the DEBUG, INFO, WARN, and ERROR levels.

Not all levels are available for all categories. Only the levels that correspond to one or more events are available.

Note

  • NONE
  • ERROR
  • WARN
  • INFO
  • DEBUG
  • FINE
  • FINER
  • FINEST

Before running a deployment, verify that the Apex Code log level isn’t set to FINEST. Otherwise, the deployment is likely to take longer than expected. If the Developer Console is open, the log levels in the Developer Console affect all logs, including logs created during a deployment.

Important

Debug Event Types

The following is an example of what is written to the debug log. The event is USER_DEBUG. The format is timestamp | event identifier:
  • timestamp: Consists of the time when the event occurred and a value between parentheses. The time is in the user’s time zone and in the format HH:mm:ss.SSS. The value in parentheses represents the time elapsed in nanoseconds since the start of the request. The elapsed time value is excluded from logs reviewed in the Developer Console when you use the Execution Log view. However, you can see the elapsed time when you use the Raw Log view. To open the Raw Log view, from the Developer Console’s Logs tab, right-click the name of a log and select Open Raw Log.
  • event identifier: Specifies the event that triggered the debug log entry (such as SAVEPOINT_RESET or VALIDATION_RULE).

    Also includes additional information logged with that event, such as the method name or the line and character number where the code was executed. If a line number can’t be located, [EXTERNAL] is logged instead. For example, [EXTERNAL] is logged for built-in Apex classes or code that’s in a managed package.

    For some events (CODE_UNIT_STARTED, CODE_UNIT_FINISHED, VF_APEX_CALL_START, VF_APEX_CALL_END, CONSTRUCTOR_ENTRY, and CONSTRUCTOR_EXIT), the end of the event identifier includes a pipe (|) followed by a typeRef for an Apex class or trigger.

    For a trigger, the typeRef begins with the SFDC trigger prefix __sfdc_trigger/. For example, __sfdc_trigger/YourTriggerName or __sfdc_trigger/YourNamespace/YourTriggerName.

    For a class, the typeRef uses the format YourClass, YourClass$YourInnerClass, or YourNamespace/YourClass$YourInnerClass.

The following is an example of a debug log line.
Debug Log Line Example Debug Log Line Example
In this example, the event identifier is made up of the following:
  • Event name:
    1USER_DEBUG
  • Line number of the event in the code:
    1[2]
  • Logging level the System.Debug method was set to:
    1DEBUG
  • User-supplied string for the System.Debug method:
    1Hello world!
This code snippet triggers the following example of a log line.
Debug Log Line Code Snippet Debug Log Line Code Snippet
The following log line is recorded when the test reaches line 5 in the code.
115:51:01.071 (55856000)|DML_BEGIN|[5]|Op:Insert|Type:Invoice_Statement__c|Rows:1
In this example, the event identifier is made up of the following.
  • Event name:
    1DML_BEGIN
  • Line number of the event in the code:
    1[5]
  • DML operation type—Insert:
    1Op:Insert
  • Object name:
    1Type:Invoice_Statement__c
  • Number of rows passed into the DML operation:
    1Rows:1

The following event types are logged. The table lists which fields or other information is logged with each event, and which combination of log level and category causes an event to be logged.
