Telemetry

As described in the privacy policy in each Mattermost server, telemetry data optionally shared from your Mattermost servers is used to identify security and reliability issues, to analyze and fix software problems, to help improve the quality of Mattermost software and related services, and to make design decisions for future releases.

Telemetry data is encrypted in transit, does not include personally identifiable information or message contents, and details of how the information is used and processed is available in our Privacy Policy.

We use the data for the following purposes to:

  • Identify security and reliability issues.

  • Analyze and fix software problems.

  • Help improve the quality of Mattermost software and related services.

  • Make design decisions for future releases.

Note

Telemetry data collection is enabled by default for all Mattermost deployments. Self-hosted system admins can opt out of sharing telemetry data from Mattermost self-hosted servers within the System Console. Cloud system admins can’t disable telemetry for Mattermost Cloud workspaces.

Security update check feature

New threats to system security constantly arise. To alert you of relevant, high priority security updates, Mattermost servers are configured to share diagnostic information with Mattermost Inc. so that we can provide appropriate alerts.

The following data is collected once every 24 hours:

  • Mattermost server build number and version

  • Type of build (Enterprise Edition or Team Edition)

  • Server operating system

  • The server diagnostic ID (same as the ID accessing the push notification proxy, and is used to prevent double-counting of telemetry data)

  • Database type

  • Database version

  • Number of teams

  • Number of users

  • Number of active users

  • Whether or not the unit tests have been run

  • Date and time of the last check for security updates

  • The location of the Amazon Cloudfront server used for telemetry data

Opt out

To opt out, you can disable this security update check feature for self-hosted deployments in the System Console by going to Environment > SMTP > Enable Security Alerts. See the enable security alerts documentation for details. When this feature is disabled, you will not receive any security alerts.

Error and diagnostics reporting feature

Mattermost error and diagnostic data is collected for the following purposes:

  • To add improvements that are specific to your usage, upgrade, and deployment patterns, including identifying security and reliability issues.

  • To analyze and fix software problems.

  • To help improve the quality of Mattermost software and related services.

  • To make design decisions for future releases.

Note

Error and diagnostic reporting is sent by Mattermost to the endpoint api.segment.io. From Mattermost v5.23, the segment endpoint is being deprecated in favor of https://pdat.matterlytics.com, a custom Rudder domain. From Mattermost v5.26, when this feature is enabled, any 500 errors will automatically be sent to the Mattermost-hosted Sentry endpoint.

Opt out

To opt out, you can disable the error and diagnostics reporting feature for self-hosted deployments in the System Console by going to Environment > Logging > Enable Diagnostics and Error Reporting. See the enable diagnostics and error reporting documentation for details.
