Catalog of eFTL Metrics

This table describes metrics that you can use to assess the operation of eFTL channels.

Each TIBCO eFTL server is itself a application process, and tracks application metrics: for example, metrics for the server's endpoints, and metrics for the transports that implement those endpoints. See Client Metrics.

The sampling interval for eFTL metrics is fixed at 2 seconds. You cannot change this interval.
