Agent

See main docs at Agents

Running an agent as a system service

Start an agent as a system daemon via CLI command

Agent could be started as a system daemon via cli command:

dx agent start --system

This command will run an agent as launchd service (macOS users) or as a systemd service (Linux users).

Other useful commands:

dx agent list --system
dx agent restart --system
dx agent stop --system

Alternatively, manual setup could be used (see below).

Install agent as a launchd service (macOS users) - manual setup

1. Install DXOS CLI with steps in Installation section.
2. Replace ??NODE_PATH?? in "./init-templates/org.dxos.agent.plist" with output of command dirname $(which node)
3. Replace ??DX_PATH?? in "./init-templates/org.dxos.agent.plist" with output of command which dx
4. Copy ./init-templates/org.dxos.agent.plist -> ~/Library/LaunchAgents/org.dxos.agent.plist
5. Run launchctl load -w ~/Library/LaunchAgents/org.dxos.agent.plist

Stop agent started by launchd

1. Run launchctl unload -w ~/Library/LaunchAgents/org.dxos.agent.plist
2. Remove ~/Library/LaunchAgents/org.dxos.agent.plist

Install agent as a systemd service (Linux users) - manual setup

1. Install DXOS CLI with steps in Installation section.
2. Copy ./init-templates/dxos-agent.service and ./init-templates/pre-dxos-agent.service -> ~/.config/systemd/user/
3. Run systemctl --user daemon-reload to make the systemd daemon aware of the service
4. Run systemctl --user enable dxos-agent to enable the service to start automatically
5. Optionally, run sudo loginctl enable-linger {USERNAME} to enable the service to start without user login (replace {USERNAME} with the name of the user that will run the service)
6. Run systemctl --user start dxos-agent to start the service

Start agent with CLI

Agent is automatically started by each command that requires Client (to avoid this behavior use --no-agent flag). You can use --profile flag (default value is default) to run agent in an isolated profile, and --foreground to run agent in attached process.

dx agent start

see: dx agent start

Adding Agent to your Composer Identity

1. Go to Composer. And create a device invitation.

2. Run halo join command in your terminal.

3. Proceed with invitation

Troubleshooting

1. Make sure you are running the latest version of the shared worker in the browser. Go to the shared workers tab chrome://inspect/#workers, kill dxos-vault worker, then reload the Composer tab.
2. Restart your agent with dx agent restart. Also useful command dx agent stop --all

Danger Zone

1. Reset Storage. Warning: Agent will lose its storage, and config file will be deleted dx reset --force

Development

Multiple Profile configuration

Both the CLI and agents can be configured to use a given profile using either the --profile flag or DX_PROFILE environment variable. The CLI will automatically connect to the agent using the given profile.

Local development

The CLI can be invoked out of the Git monorepo using the bin/dev command.

Source the following script to set an alias for dx that can be called from any directory:

cd packages/devtools/cli
. ../../devtools/cli/scripts/dev.sh

Example:

DX_PROFILE=test dx agent start  --ws=4567

NOTE: The agent will need to be recompiled after any changes.

Building

To build the CLI:

nx run cli:build --watch=true

Devtools

The agent can be configured to expose a Websocket port using the --ws flag that can be connected to using DXOS Devtools:

To connect devtools, set the target query parameter to the agent's websocket URL, e.g.,

https://devtools.dxos.org?target=ws://localhost:4567

Debugging

To enable logging, set LOG_FILTER:

LOG_FILTER=info,agent:debug dx agent start -f

If the agent is run in background mode, log files will be created in /tmp/dx/run/profile/<profile name>/logs

To enable the node debugger, set NODE_OPTIONS then open in VSCode (CMD-SHIFT-P "Attach to Node process").

NODE_OPTIONS="--inspect-brk"

Reporting errors

Run the following command to create a gist of the debug stats.

dx debug stats --json --no-agent | gh gist create
