Laravel Queue Watchdog

A Laravel package to monitor queue failures and send notifications based on thresholds and time windows.

Features

• Digest Mode (Time-Bucket): Instead of immediate alerts, it collects all failures within a time window and sends a summary report.
• Threshold Monitoring: Alert only when X jobs fail within Y minutes.
• Queue Filtering: Precisely control which queues to monitor (supports wildcards and exclusions).
• Aggregation Strategies:
  • all: Count all failures.
  • unique_jobs: Count failures per job class.
  • unique_exceptions: Count failures per exception type.
• Cooldown: Prevent notification spam with a configurable cooldown period after a report is sent.
• Multi-channel Notifications: Support for Mail, Slack, and any other Laravel notification channel.

Installation

Note: If you plan to use the Slack notification channel, you must also install the official Laravel Slack notification package:

Configuration

Publish the config file:

or

The configuration allows you to define thresholds, aggregation strategies, and notification channels.

How it works: Digest Mode

The watchdog uses a Time-Bucket model to ensure no failure information is lost:

1. The first failure on a monitored queue starts a "Collection Window" (defined by window_minutes).
2. All subsequent failures during this window are collected in a cache-based bucket.
3. At the end of the window, an analysis job runs.
4. If the total count of failures is >= failure_limit, a summary notification is sent via your configured channels.
5. A cooldown_minutes period then starts, during which no new collection windows will begin.

Configuration Tips:

• Real-time Alerts: Set window_minutes to 0 or false and failure_limit to 1 to receive a notification immediately for every failure.
• Strict Digest: Set window_minutes to 10 and failure_limit to 1 to get a summary of all failures every 10 minutes.
• Threshold Digest: Set window_minutes to 5 and failure_limit to 10 to only be notified if at least 10 jobs fail within a 5-minute burst.

Queue Filtering

You can precisely control which queues are monitored using the queues array in the config file. It supports wildcards and exclusions:

• *: Monitor all queues.
• default: Monitor only the "default" queue.
• !ignored: Exclude the "ignored" queue.
• sync*: Monitor any queue starting with "sync" (e.g., sync-users, sync-orders).

Example:

Usage

The package automatically listens for the Illuminate\Queue\Events\JobFailed event and tracks failures in your cache. No additional setup is required beyond configuration.
