README

A self-hostable Laravel instrumentation and local agent starter, adapted from the public laravel/nightwatch package architecture and transport ideas, but renamed and reshaped for Dozor.

What this bundle gives you

• Laravel package with dozor:agent and dozor:status commands
• local TCP ingest client/server using a framed payload protocol
• request tracing middleware
• query, queue, and exception watchers
• newline-delimited JSON storage for ingested records
• configuration already renamed from NIGHTWATCH_* to DOZOR_*

What this is not

• not a drop-in clone of the hosted Nightwatch backend
• not a full production-ready APM yet
• not a fork that keeps Laravel/Nightwatch branding

It is a good self-hosted starter: clean enough to keep, small enough to reshape.

Install

composer require pepperfm/dozor-agent
php artisan vendor:publish --tag=dozor-config

Local package smoke install (path repository)

{
  "repositories": [
    {
      "type": "path",
      "url": "../dozor-agent",
      "options": {
        "symlink": true
      }
    }
  ]
}

composer require pepperfm/dozor-agent:*
php artisan list | grep dozor:
php artisan vendor:publish --tag=dozor-config

Install is safe even if the local worker is not running yet. The package does not break composer install, deploy hooks, or package:discover when 127.0.0.1:4815 is unavailable. You can install first and start the worker later.

Typical env

DOZOR_ENABLED=true
DOZOR_TOKEN=change-me
DOZOR_APP_NAME="My App"
DOZOR_ENV=production
DOZOR_SERVER=app-1
DOZOR_INGEST_URI=127.0.0.1:4815
DOZOR_INGEST_EVENT_BUFFER=500
DOZOR_REQUEST_SAMPLE_RATE=1.0
DOZOR_IGNORE_QUERIES=false
DOZOR_AGENT_STORE_PATH=/var/www/app/storage/app/dozor
DOZOR_AGENT_SHIP_FLUSH_INTERVAL_SECONDS=10

Run local agent

php artisan dozor:agent

Useful options:

php artisan dozor:agent --listen-on=127.0.0.1:4815 --store-path=/var/www/app/storage/app/dozor
php artisan dozor:agent --ship-flush-interval-seconds=10
php artisan dozor:status
php artisan dozor:status --json
php artisan dozor:status --strict

dozor:status --strict is opt-in diagnostics and may fail when the local worker is down. Regular runtime instrumentation stays non-fatal and keeps buffered retry behavior.

Runtime telemetry and status

dozor:status now reports:

• local agent reachability (ping)
• queue depth and failed queue depth
• dropped batches and failed upload counters
• last flush / heartbeat / upload timestamps

Shipping strategy is strict batching by default and cannot be toggled via config flags.

Telemetry state is persisted to:

DOZOR_AGENT_STATE_PATH=/var/www/app/storage/app/dozor/runtime-state.json

Production packaging examples

Example service files are available in:

• examples/supervisor/dozor-agent.conf.example
• examples/systemd/dozor-agent.service.example

Current record model

The package emits records like:

• request
• query
• job
• exception
• custom

Each record includes a trace_id, timestamps, app/environment/server metadata, and a payload block.

Files worth editing first

• src/DozorServiceProvider.php
• src/Core.php
• src/Http/Middleware/TraceRequest.php
• src/Agent/Server.php
• config/dozor.php

Suggested next steps

1. swap NDJSON file storage for ClickHouse / Postgres / Kafka / Redis Streams
2. add outgoing HTTP instrumentation
3. add trace/span hierarchy instead of flat child records
4. add metric rollups (minute buckets, P95/P99)
5. correlate deployments/releases
