Relago

Automatic crash reporting tool for XinuxOS. It monitors your system for crashes, collects diagnostic information, and lets you submit reports through a simple GUI.

What it does

Relago runs as a background daemon that watches the systemd journal for crash events. When it detects a crash, it sends a desktop notification and opens a GUI window where you can review the crash details and choose to send a report.

Detected crash types:

• Coredumps (application crashes)
• Service failures (systemd unit failures)
• Out-of-memory kills (OOM events)

When you send a report, Relago collects:

• System information (CPU, memory, disk usage, network interfaces)
• Systemd journal entries
• NixOS/XinuxOS configuration files (if available)

If the user clicks "Send Report" in the GUI, everything is compressed into a ZIP file and uploaded to the report server. If the user clicks "Cancel", the report is discarded.

Installation

# clone the repository
git clone https://github.com/xinux-org/relago
cd relago

# build in release mode (requires GTK4, libadwaita, systemd dev libraries)
cargo build --release

# binary location after build
./target/release/relago

Commands

daemon

# before running daemon, create the config directory and file
sudo mkdir -p /var/lib/relago
sudo touch /var/lib/relago/config.toml

# start the crash monitoring service
# watches systemd journal for coredumps, service failures, and OOM events
# when crash detected: extracts details -> shows desktop notification -> opens reporter GUI
cargo run -- daemon

# start with a custom instance name
cargo run -- daemon myinstance

report

Default location: /tmp/relago/report_YYYY-MM-DD_HH-MM-SS/

# generate a diagnostic report (saved as ZIP)
# collects: system info, journal entries, nixos config
# saves in the default location if you don't specify one
cargo run -- report

# save report to specific directory
cargo run -- report -o /path/to/output

# only include last 100 journal entries (faster, smaller report)
cargo run -- report -r 100

# include nixos configuration in the report
cargo run -- report --nixos-config /etc/nixos/xinux-config

# combine options
cargo run -- report -o ./my-report -r 500 --nixos-config ~/nixos-config

reporter

# open the crash reporter GUI window
# shows crash details, send button, upload progress
cargo run -- reporter

# specify crash details (usually called by a daemon)
cargo run -- reporter -u firefox.service -e firefox -m "Segmentation fault"

# -u : systemd unit name
# -e : executable name
# -m : crash message

Testing crash detection

To manually trigger a crash for testing, use the crash project.

# install crash tool
git clone https://github.com/xinux-org/crash
cd crash

# it is used to update the flake.lock file
nix flake update

# first, start relago daemon in ~/relago project terminal
cargo run -- daemon

# then, run this command to force a crash manually in ~/crash project terminal
nix run .\#segfault

Configuration

Configuration file: /var/lib/relago/config.toml

# number of threads for compression
parallel_compression = 4

# temporary directory for report generation
tmp_dir = "/tmp/relago"

# data storage directory
data_dir = "/var/lib/relago/data"

# path to nixos configuration
nix_config = "/etc/nixos/xinux-config"

# report upload server URL
server = "https://example.com"
