| # Fuchsia DevTools |
| |
| Fuchsia DevTools is a tool for displaying the vital signs of a Fuchsia device |
| and its processes. Samples are collected for global and per-process CPU, memory |
| usage, and process list. Samples are then relayed to the host machine for |
| display. |
| |
| Fuchsia DevTools has the following parts: |
| |
| - [GUI or CLI program](#gui-or-cli-program) |
| - [Dockyard library](#dockyard-library) |
| - [Transport](#transport) |
| - [Harvester](#harvester) |
| |
| ## GUI or CLI program {#gui-or-cli-program} |
| |
| At the highest level, the UI displays samples collected from the Fuchsia device |
| (in graphs or charts as appropriate), which come from the Dockyard on the host. |
| The GUI for Fuchsia DevTools is not included in this source directory. It is |
| implemented at a higher level. |
| |
| ## Dockyard library {#dockyard-library} |
| |
| The [Dockyard](dockyard/README.md) is a library that collects data from the |
| Harvester running on the Fuchsia device. |
| |
| ## Transport |
| |
| The communication between the Harvester and the Dockyard is handled by the |
| Transport. The Transport (which is made up of libraries, source code, and |
| protocol definitions) is used on both the host machine and the Fuchsia device. |
| |
| ## Harvester |
| |
| The [Harvester](harvester/README.md), running on the Fuchsia device, acquires |
| samples (units of introspection data) and sends them to the host machine using |
| the Transport system. |
