View app logs

App logs give you the information you need in order to debug your apps. Logs are enabled by default when a user installs your app, and are displayed in the developer console. If you need to view app logs for a site where the user has disabled log access, you can ask them to re-enable access.

Before you begin

The content on this page is written under the assumption that your Forge app is running on an older version of Forge runtime.

On the older version, the Logs screen would display like the following:

A list of logs and the associated filters

If you see a different screen, your Forge app may be on a newer version of Forge runtime. The new experience provides capabilities that further refine log results, including using new filters, such as log levels, and searching for log messages.
If you want to move your app to the new runtime, run forge deploy in the Forge CLI. Site admins may need to provide consent if a major version upgrade of their app is required.

View app logs

To view app logs:

Access the developer console.
In the left menu, select Logs.

The screen shows logs for all sites that users have granted you access to.

A list of logs and the associated filters

A maximum of 20 log events are displayed by default. To view more log events, select Load more logs at the bottom of the page.

Log table

The table contains a list of your logs.

Level: Displays the log level. This can be chosen by your app, by inserting log statements such as console.log, console.warn in your app’s code. Unhandled errors are assigned the Error level, and include both app errors and platform errors.
Date/Time(UTC): Displays the time that the log was created in UTC.
Details: Shows a concatenated preview of the log message. Select anywhere in a row to expand it and view the entire log message. See Log messages for more details.

Logs are shown for a single invocation. To see logs for another invocation, select Load logs for another invocation.

Log attributes

Expanding a row in the log table lets you view all log details, including the attributes from the state of the app.

Invocation ID: A unique identifier for the specific app invocation that generated the log lines.
Trace ID: A request identifier that can be used to track log lines across different Forge invocations and remote API calls.
Module: The name of the module where this log line was generated.
Function: The name of the function where this log line was generated.
Version: The version of the app that's installed on the site.
Site: The name of the site where the app was invoked from.
Environment: The specific environment (development, staging, or production) where the app is currently running in.
Product: The Atlassian product onto which the app is installed.

Filters

You can use filters to further refine your logs. Depending on the version of Forge Runtime that the app is on, you may have varying filters that you can use.

Site: Narrows down the logs based on the site that your app is installed onto, for example, https://your-domain.atlassian.net. You can select multiple sites.
Environment: Narrows down the logs for a specific app environment for your Forge app.
Time range: Narrows down the logs for a specific time range that you set. Choose from a range of predefined values, such as the Last 24 hours, or choose a more specific time interval using the Custom option.

You can’t filter by product. For example, you can’t narrow down logs just for Jira instances on a particular site.
Logs are only available for the past 60 days and all dates are in UTC.
To clear your filters, select Reset to default.
To download a zipped file of the logs for your chosen filters, select the Download button.
The maximum file size of filtered logs you can download is 100MB.

Limitations

The log access functionality in the developer console is an evolving feature.

When filtering by multiple sites, data is aggregated from all selected sites, rather than individual sites.
Logs for only a maximum of 95 app installations can be displayed at a given time. We recommend using filters to view logs for specific sites.
Log filters don't include filtering by log level (warn or info).

View app installations

To see a list of sites that your app is currently installed onto, select Installations in the left menu.
