Monitor the Tetra Data Platform Health

The Tetra Data Platform (TDP) Health Monitoring Dashboard provides an end-to-end snapshot of your components' health and performance across your entire TDP ecosystem.

The Health Monitoring Dashboard provides performance and health status visualizations for each of these TDP components and event types:

View the Health Monitoring Dashboard

To view the Health Monitoring Dashboard, do the following:

  1. Sign in to the TDP as an admin user.
  2. In the left navigation menu, choose Health Monitoring. The Health Monitoring page appears with the Dashboard tab selected by default, which displays an end-to-end snapshot of your components' health for your entire TDP ecosystem.

Component Health Status

The top section of the Dashboard tab indicates the health status of each TDP component. The status is indicated by a statistical visualization of how many instances of a component are in a Healthy, Unhealthy, or Critical state. Each visualization also provides a file Total for each component type.

Statistical Visualization Example

Possible Health Statuses for Components

Possible StatesDefinitionExample
HealthyIndicates that the component is operating optimally within specified parameters. What is considered optimal differs by component.A healthy connector makes a connection within three attempts.
UnhealthyIndicates that the component is not operating optimally, but has not failed. What is considered optimal differs by component.An unhealthy datahub has a memory usage value that is greater than 80% but less than, or equal to 90%, for the past five contiguous minutes.
CriticalIndicates that the component has failed or is well outside the specified parameters. Similar to the Healthy and Unhealthy states, the exact elements that contribute to the Critical state differs by component.If the percentage of used disk space for a Tetra Agent is greater than 90%, then that component is in a critical state.

Problems

The bottom section of the Dashboard tab on the Health Monitoring Dashboard displays a detailed list of component instances with Critical issues.

NOTE

To review information for components that aren't in a Critical state, you must view the specific dashboard for each TDP component.

Filtering Problems

You can filter any listed problems by the following filter types:

  • All
  • Agents
  • Data Hubs (now Tetra Hub v1s)
  • Data Hub Connectors (now Tetra Hub v1 Connectors)
  • Cloud Connectors.

Each component listed in the Problems section of the Health Monitoring Dashboard includes the following information:

FieldDescription
Health Health status.

Note: Only Critical issues display.
Name Name (and representative icon) of the component instance that is currently in the Critical state.

To sort the list of components by name, click the arrow next to Name at the top of the column. You can sort items alphabetically, or in reverse order.

To view additional details about the component, you can hover over the name. The information that displays is customized based on the component type.

To copy the unique ID for the component instance, select the copy file icon.
Latest StatusWhen the latest status (Date/Time format) was assigned, and whether its currently Active or Disabled. To review a component's status history, select the View History link below the status.
Health Description Explains why the component has been assigned a Critical status (shown by issues and/or warnings). By default, one issue is shown only. If there is more than one issue, then a link displays (for example, +1 More) indicating that there are additional issues to review.
Link Provides a link that you can select to review the configuration details for the component.

View Component Status History

If available, you can click View History from the LATEST STATUS column to review a component's list of status changes. TDP polls each component every five minutes. If a change of status occurs during the five minute polling interval, then an entry is added to the component's status history.

Available Component Status Historical Data

The following component status historical data is available for each component type:

  • Time: In date/time format, indicating when a status change occurred
  • Change: Shows the status change
  • Errors: Displays any error(s) that caused the component status to change
  • Warnings: Displays any warning(s) that caused component status to change
