ffx process_explorer

This ffx plugin allows retrieving information about Fuchsia processes.

In particular, the plugin can list channels, event and sockets held by processes on a running Fuchsia device, allowing analysis of the topology of connections between processes.

Run

The plugin needs a support component not included in the build by default. Build the Fuchsia image with the following additional package:

$ fx set [...] --with-base src/developer/process_explorer

Then run the plugin:

ffx process_explorer

Usage example

$ ffx process_explorer list | grep archivist
  2257   archivist.cm

$ ffx process_explorer filter 2257
Total processes found:    1

Process name:             archivist.cm
