# Installing XDS client tools

[xds-agent](https://github.com/iotbzh/xds-agent) is a client tool that must run
on your machine (user / developer host) to be able to use XDS.

Installation of other XDS client tools, such as `xds-exec` or `xds-gdb` is
optional and depends of what you want to do :

- [xds-exec](https://github.com/iotbzh/xds-exec) : command line tool to interact with XDS (also used by IDE integration).
- [xds-gdb](https://github.com/iotbzh/xds-gdb) : requested for debugging application.

  1. Add binary to PATH:
    - MacOs: create the .bash_profile `nano .bash_profile` and add `export PATH="/opt/AGL/xds/xds-agent:$PATH`

  - `xds-exec` : requested for command line and IDE integration. ([released tarball link](https://github.com/iotbzh/xds-exec/releases)).
  - `xds-gdb` : requested for debugging application. ([released tarball link](https://github.com/iotbzh/xds-gdb/releases)).

## Start xds-agent

XDS-agent is a client tool that must run on your local / user development
machine when you use XDS.

For Linux distro, a user systemd service is provided, so you just need to enable
if you want to start it automatically at boot and you can also start it
immediately using following commands:

```bash
# Enable xds-agent service at boot
seb@laptop ~$  systemctl --user enable xds-agent.service

# Manually start xds-agent service
seb@laptop ~$  systemctl --user start xds-agent.service

# Get status and log of xds-agent service
seb@laptop ~$  systemctl --user status xds-agent.service
```
