The following are the Health Monitoring App release notes for versions 1.x. The Health Monitoring App provides a comprehensive dashboard in the Tetra Data Platform (TDP) user interface to help customers gain an end-to-end understanding of data downtime. The dashboard provides a set of metrics for ingestion failures and latency for on-premises Tetra File-Log Agents and Tetra Data Pipelines.

v1.0.0

Release date: 30 June 2025

What's New

TetraScience has released its first general availability (GA) version of the Health Monitoring App (previously known as the Superset Monitoring App), version 1.0.0. This release introduces persistence for Superset metadata, including charts, dashboards, and authentication sessions. It also introduces several new graphs for Empower and a new Chromeleon tab.

Prerequisites

Health Monitoring App v1.0.0 requires the following:

• Tetra Data Platform (TDP) v4.3.0 or higher
• Customers must contact TetraScience to have the app activated in their TDP environment

New Functionality

New Functionality includes features not previously available in the Health Monitoring App.

• Superset metadata persistence: Any changes made to the app configuration now persist between user sessions, and when customers upgrade to the latest app version.

Enhancements

Enhancements are modifications to existing functionality that improve performance or usability, but don't alter the function or intended use of the system.

• New Empower charts were added for latency, top injections, and projects.
• An Agent Name field was added to charts relating to Agents, and users can now filter by Agent name.
• A new tab for Tetra Chromeleon Agents was added.

Bug Fixes

The following bugs are now fixed:

• User cookies are now persisted, which solves intermittent 500 internal server errors when the app is activated. However, a 500 error may still be seen when upgrading to the latest app version. To resolve the issue, customers should log out of the TDP, close their web browser, and then reopen the browser and sign back in to the TDP.

Limitations

The following are known limitations of Health Monitoring App v1.0.0:

• Metrics data isn't backfilled when the app is activated, so the available data spans one day in duration only when the new Health Monitoring dashboard first appears in customers' TDP environments.
• If the available data spans one day in duration only (for example, when the new dashboard is first activated) then charts in the new Health Monitoring dashboard will appear empty. If customers hover their cursors over an empty chart, they will see a single data point, which is a summary statistic for that day. Once customers have two days of data available, then the charts and tables will populate as normal.
• The File Ingestion Journey chart on the FLA tab won't show any file search indexing events or other downstream file events if those events occur outside of the Time range filter defined by customers. This behavior occurs because all File Ingestion Journey events are a subset of the original files that were scanned during the specified time range.
• There is a maximum number of table rows available for each of the following troubleshooting metrics:
  • Last Agent Heartbeat: 100 row maximum
  • File Status: 1,000 row maximum
  • Workflow Status: 1,000 row maximum
  • Path Status (Latest Scan): 1,000 row maximum

Deprecated Features

There are no new deprecated features in this release. For more information about TDP deprecations, see Tetra Product Deprecation Notices.

Known and Possible Issues

The following are known issues for Health Monitoring App v1.0.0:

• After being activated, the Health Monitoring App may return a 500 internal server error as it establishes a new user database. To resolve the issue, customers should log out of the TDP, close their web browser, and then reopen the browser and sign back in to the TDP.
• After selecting Enter fullscreen on a graph, the graph can sometimes fail to render and an error appears. To resolve the issue, navigate back to the dashboard and re-enter the fullscreen view.

Security

The Health Monitoring App implements the following security measures:

• All dashboard data is encrypted in transit using TLS 1.2+
• Access to metrics is controlled through TDP's role-based access control system
• Audit logging tracks all dashboard configuration changes
• Alert configurations are encrypted at rest

Upgrade Considerations

When activating the Health Monitoring App, keep in mind the following:

• After being activated, the app may return a 500 internal server error as it establishes a new user database. To resolve the issue, customers should log out of the TDP, close their web browser, and then reopen the browser and sign back in to the TDP.
• The app might also display a Workgroup Not Found error when opened for the first time. To resolve the issue, customers must rotate their organization-level SQL Credentials. Keep in mind, the new set of generated credentials will cause the previous set of credentials to stop working.
