[ bsd3, debug, deprecated, library, monitoring, program, system ] [ Propose Tags ] [ Report a vulnerability ]
Deprecated in favor of eventlog-live

This executable collects telemetry data from any Haskell application and sends it over the OpenTelemetry protocol. The next release of this executable will be as part of the eventlog-live package under the name eventlog-live-otlp.

For more information, see the README.
