There is a section on the LoadMaster device details page that shows a summary of the LoadMaster health over time. This allows you to easily see when the LoadMaster was unavailable and explore further to determine the state and the number of times this state happened. This chart makes you aware of historical loss of services.

The availability bar displays a horizontal timeline for each of the last seven days.

Each bar is divided into time‑based segments that indicate the LoadMaster’s actual state during different periods of the day. The visualization may include the following states:

  • Down (the LoadMaster is unreachable)
  • Available
  • At Risk (the status of a LoadMaster is unknown because the Connector is unreachable or there is a loss of redundancy for High Availability (HA) pairs)
  • No data available (black): Displayed for time periods prior to the creation/addition of the LoadMaster, when no monitoring data is available. For example, if a LoadMaster was created/added on Friday, no data is shown for any time period before its creation/addition.

A detailed state‑duration table beneath the availability bar provides a breakdown of every state change observed during the past seven days, including:

  • Start: The date of the recorded state.
  • Status: Whether the Virtual Service status was reachable, unreachable, unknown, or if there was no data available.
  • From / To: The exact times during which the state occurred.
  • Duration: The total time the LoadMaster remained in that state.

If you are viewing the LoadMaster details page for a HA pair - a separate chart (Active device over time) displays the status of each individual LoadMaster over time. If each of the two LoadMasters becomes active at some point throughout the day (that is, a failover has occurred), the graph shows a purple color for both LoadMasters during the affected period. You can hover over a day in the chart to get further details.
