Overview Status Page

Use this page for a high-level summary of an FTL server cluster, including its persistence clusters.

Note: An FTL server cluster consists of core and auxiliary FTL servers running at a single site. The FTL server GUI displays the status of a single FTL server cluster. For more information, see FTL Server and Services.

FTL Server Summary

This table lists all FTL servers in the FTL server cluster.

Click a row to navigate to the details page for an FTL server. Actions are available on the details page. See FTL Server Details Page].

Field Description
Host CPU

Total CPU usage on the host where FTL server is running, expressed as a percentage of available CPU resources.

For example, if all CPUs on the host are completely busy, this value is 100%. If half the CPUs are busy, this value is 50%.

Note: In containerized environments, there might be processes consuming CPU that are not visible to FTL server.
Host CPU Count

The number of CPUs (hardware threads) on the host where FTL server is running.

Note: In containerized environments, there may be CPU limits that prevent FTL server from using all available CPUs.
Host Memory Usage

Displays the amount of memory in use on the host where FTL server is running, as well as the total memory on the host.

Note: In containerized environments, there may be processes consuming memory that are not visible to FTL server.
Note: In containerized environments, there may be memory limits that prevent FTL server from using all available memory.
Server CPU

CPU usage of the FTL server.

For example, a value of 150% indicates that FTL server is consuming one and a half CPUs worth of CPU time.

Server Memory Usage Memory usage of the FTL server.

Persistence Cluster Summary

A persistence cluster is a set of cooperating persistence services that run in FTL servers. This table lists all the persistence clusters provided by the current FTL server cluster.

Typically, there is one default persistence cluster. You may configure additional persistence clusters if more bandwidth is required. See Persistence: Stores and Durables.

Field Description
Pending Msgs

The total number of messages stored by a persistence cluster.

A large number may indicate slow or offline consumers.

Inbound Msg Rate

The rate at which the persistence cluster is receiving messages from producers or routes.

Note: The default persistence cluster handles internal monitoring data. The inbound msg rate for the default persistence cluster includes internal monitoring data.
Outbound Msg Rate The rate at which the persistence cluster is delivering messages to consumers or routes.
