Monitoring gitGost

Monitor your gitGost instance to ensure healthy operation and detect issues early.

Health Check Endpoint

The /health endpoint provides service status and build information.

Check Service Health

curl https://gitgost.leapcell.app/health

Response:

{
  "status": "healthy",
  "deployedCommit": "a3f7b9c",
  "deployedAt": "2024-03-05T10:30:00Z",
  "sourceRepo": "https://github.com/livrasand/gitGost",
  "leapcell": true,
  "goVersion": "go1.21.5",
  "verify": {
    "github": "https://github.com/livrasand/gitGost/commit/a3f7b9c",
    "source": "100% open source - auditable"
  }
}

The verify.github URL allows you to audit the exact source code running on the server. This ensures transparency and builds trust.

Health Check Integration

Add to monitoring dashboard

Configure your monitoring tool (Prometheus, Datadog, etc.) to poll /health every 30-60 seconds.

Set up alerts

Alert when:

/health returns non-200 status
Response time exceeds 5 seconds
Service becomes unreachable

Verify deployments

After deploying, check the deployedCommit matches your expected commit hash.

Metrics Endpoint

The /metrics endpoint exposes runtime metrics for performance monitoring.

Fetch Metrics

curl https://gitgost.leapcell.app/metrics

Response:

{
  "memory": {
    "alloc": 4567890,
    "total_alloc": 123456789,
    "sys": 23456789,
    "num_gc": 42
  },
  "goroutines": 15,
  "uptime": "12h34m56s"
}

Key Metrics

Metric	Description	Normal Range
`memory.alloc`	Current heap allocation (bytes)	< 100 MB
`memory.num_gc`	Number of GC cycles	Increases over time
`goroutines`	Active goroutines	< 100 (idle), < 500 (busy)
`uptime`	Time since service started	N/A

High Memory Alert: If memory.alloc exceeds 500 MB consistently, investigate for memory leaks or consider scaling.

Service Status Endpoint

The /api/status endpoint shows if the panic button is active.

curl https://gitgost.leapcell.app/api/status

Response:

{
  "panic_mode": false
}

panic_mode: false → Service accepting pushes normally
panic_mode: true → Service suspended (panic button activated)

Logging System

GitGost uses privacy-focused logging that minimizes user data exposure.

Log Format

Configure log format via the LOG_FORMAT environment variable:

# Text format (default)
LOG_FORMAT=text

# JSON format (structured)
LOG_FORMAT=json

Text Format Logs

JSON Format Logs

{"timestamp":"2024-03-05T10:30:45Z","level":"info","message":"Privacy mode: Minimal logging enabled","privacy":"anonymized"}

Log Privacy Features

From internal/utils/logging.go:

Privacy-First Logging Design

No IP addresses logged in push operations
No user metadata captured or stored
Minimal context to prevent correlation attacks
All logs tagged with "privacy": "anonymized"
Logs focus on service health, not user activity

Privacy Notice: GitGost logs are designed to protect user anonymity. Do not add custom logging that captures IP addresses, user agents, or timing patterns that could deanonymize users.

Alert Configuration

Recommended Alerts

Service Down

Trigger: /health endpoint returns non-200 or times outAction: Immediate investigation required

# Example healthcheck script
if ! curl -sf https://gitgost.leapcell.app/health > /dev/null; then
  echo "ALERT: gitGost service is down!"
  # Send alert notification
fi

High Memory Usage

Trigger: memory.alloc > 500 MB for 5+ minutesAction: Check for memory leaks, restart if necessary

Panic Mode Activated

Trigger: /api/status returns panic_mode: trueAction: Administrator intervention required (abuse detected)

Rate Limit Exceeded

Trigger: Multiple rate limit alerts from ntfy admin notificationsAction: Review IP patterns, consider temporary panic mode

ntfy Admin Notifications

GitGost sends real-time alerts via ntfy when configured. Configure ntfy alerts:

# Set environment variables
export NTFY_ADMIN_TOPIC="your-secret-admin-topic"
export PANIC_PASSWORD="your-secure-password"

Alert types:

Rate limit exceeded: Single IP exceeds 5 PRs/hour
Suspicious burst activity: 20+ pushes from 10+ IPs in 60 seconds
Service control: Action buttons to activate/deactivate panic mode

Subscribe to your admin topic on your phone using the ntfy app for instant push notifications:

https://ntfy.sh/your-secret-admin-topic

Log Analysis Examples

Find Recent Errors

# Text format
grep "ERROR:" app.log | tail -n 20

# JSON format
jq 'select(.level == "error")' app.log | tail -n 20

Count PR Creation Events

# Text format
grep "Created PR:" app.log | wc -l

# JSON format
jq 'select(.message | contains("Created PR:"))' app.log | wc -l

Monitor Fork Creation Rate

# Track fork operations over time
grep "Fork ready:" app.log | awk '{print $1, $2}' | uniq -c

Deployment Verification

Verify deployments match the source code:

Fetch deployed commit

DEPLOYED_COMMIT=$(curl -s https://gitgost.leapcell.app/health | jq -r '.deployedCommit')
echo "Deployed commit: $DEPLOYED_COMMIT"

Compare with GitHub

git fetch origin
git log --oneline origin/main | grep "$DEPLOYED_COMMIT"

Verify source transparency

Visit the GitHub verification URL:

curl -s https://gitgost.leapcell.app/health | jq -r '.verify.github'
