CLAUDE: Enhance Tdarr monitoring with automatic staging timeout cleanup and Discord notifications
Major improvements to Tdarr monitoring system addressing staging section timeout issues: ## New Features: - **Automatic Staging Timeout Detection**: Monitors server logs for 300s limbo timeouts every 20 minutes - **Stuck Directory Cleanup**: Automatically removes work directories with partial downloads preventing staging cleanup - **Enhanced Discord Notifications**: Structured markdown messages with working user pings extracted from code blocks - **Comprehensive Logging**: Timestamped logs with automatic rotation (1MB limit) at /tmp/tdarr-monitor/monitor.log - **Multi-System Monitoring**: Covers both server staging issues and node worker stalls ## Technical Improvements: - **JSON Handling**: Proper escaping for special characters, quotes, and newlines in Discord webhooks - **Shell Compatibility**: Fixed `[[` vs `[` syntax for Docker container execution (sh vs bash) - **Message Structure**: Professional markdown formatting with separation of alerts and actionable pings - **Error Handling**: Robust SSH command execution and container operation handling ## Problem Solved: - Root Cause: Hardcoded 300s staging timeout in Tdarr v2.45.01 causing large files (2-3GB+) to fail download - Impact: Partial downloads created stuck .tmp files, ENOTEMPTY errors preventing cleanup, cascade failures - Solution: Automated detection and cleanup system with proactive Discord alerts ## Files Added/Modified: - `scripts/monitoring/tdarr-timeout-monitor.sh` - Enhanced monitoring script v2.0 - `reference/docker/tdarr-troubleshooting.md` - Added comprehensive monitoring system documentation ## Operational Benefits: - Reduces manual intervention through automatic cleanup - Self-healing system prevents staging section blockage - Enterprise-ready monitoring with structured alerts - Minimal resource impact: ~3s every 20min, <2MB storage 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

User experiencing persistent `TypeError: Cannot read properties of undefined (reading 'forEach')` error in Tdarr transcoding system. Error occurs during file scanning phase, specifically during "Tagging video res" step, preventing any transcodes from completing successfully.
|
||||
|
||||
## System Configuration
|
||||
- **Tdarr Server**: 2.45.01 running in Docker container at `ssh tdarr` (10.10.0.43:8266)
|
||||
- **Tdarr Server**: 2.45.01 running in Docker container - Access via `ssh tdarr` (10.10.0.43:8266)
|
||||
- **Tdarr Node**: Running on separate machine `nobara-pc-gpu` in Podman container `tdarr-node-gpu`
|
||||
- **Architecture**: Server-Node distributed setup
|
||||
- **Original Issue**: Custom Stonefish plugins from repository were overriding community plugins with old incompatible versions
|
||||
|
||||
### Server Access Commands
|
||||
- **SSH to server**: `ssh tdarr`
|
||||
- **Check server logs**: `ssh tdarr "docker logs tdarr"`
|
||||
- **Access server container**: `ssh tdarr "docker exec -it tdarr /bin/bash"`
|
||||
|
||||

3. **Version Rollback**: Consider temporarily downgrading Tdarr to identify if this is a version-specific regression

## Enhanced Monitoring System (2025-08-10)
|
||||
|
||||
### Problem: Staging Section Timeout Issues
|
||||
After resolving the forEach errors, a new issue emerged: **staging section timeouts**. Files were being removed from staging after 300 seconds (5 minutes) before downloads could complete, causing:
|
||||
- Partial downloads getting stuck as `.tmp` files
|
||||
- Work directories (`tdarr-workDir*`) unable to be cleaned up (ENOTEMPTY errors)
|
||||
- Subsequent jobs failing to start due to blocked staging section
|
||||
- Manual intervention required to clean up stuck directories
|
||||
|
||||
### Root Cause Analysis
|
||||
1. **Hardcoded Timeout**: The 300-second staging timeout is hardcoded in Tdarr v2.45.01 and not configurable
|
||||
2. **Large File Downloads**: Files 2-3GB+ take longer than 5 minutes to download over network to unmapped nodes
|
||||
3. **Cascade Failures**: Stuck work directories prevent staging section cleanup, blocking all future jobs
|
||||
|
||||
### Solution: Enhanced Monitoring & Automatic Cleanup System
|
||||
|
||||
**Script Location**: `/mnt/NV2/Development/claude-home/scripts/monitoring/tdarr-timeout-monitor.sh`
|
||||
|
||||
#### Key Features Implemented:
|
||||
1. **Staging Timeout Detection**: Monitors server logs for "limbo" timeout errors every 20 minutes
|
||||
2. **Automatic Directory Cleanup**: Removes stuck work directories with partial downloads
|
||||
3. **Discord Notifications**: Structured markdown messages with working user pings
|
||||
4. **Comprehensive Logging**: Timestamped logs with automatic rotation
|
||||
5. **Multi-System Monitoring**: Covers both server staging issues and node worker stalls
|
||||
|
||||
#### Implementation Details:
|
||||
|
||||
**Cron Schedule**:
|
||||
```bash
|
||||
*/20 * * * * /mnt/NV2/Development/claude-home/scripts/monitoring/tdarr-timeout-monitor.sh
|
||||
```
|
||||
|
||||
**Log Management**:
|
||||
- **Primary Log**: `/tmp/tdarr-monitor/monitor.log`
|
||||
- **Automatic Rotation**: When exceeding 1MB → `.log.old`
|
||||
- **Retention**: Current + 1 previous log file
|
||||
|
||||
**Discord Message Format**:
|
||||
```markdown
|
||||
```md
|
||||
# 🎬 Tdarr Monitor
|
||||
**3 file(s) timed out in staging section:**
|
||||
- Movies/Example1.mkv
|
||||
- TV/Example2.mkv
|
||||
- TV/Example3.mkv
|
||||
|
||||
Files were automatically removed from staging and will retry.
|
||||
```
|
||||
Manual intervention needed <@userid>
|
||||
```
|
||||
|
||||
#### Monitoring Capabilities:
|
||||
|
||||
**Server-Side Detection**:
|
||||
- Files stuck in staging section (limbo errors)
|
||||
- Work directories with ENOTEMPTY errors
|
||||
- Partial download cleanup (.tmp file removal)
|
||||
|
||||
**Node-Side Detection**:
|
||||
- Worker stalls and disconnections
|
||||
- Processing failures and cancellations
|
||||
|
||||
**Automatic Actions**:
|
||||
- Force cleanup of stuck work directories
|
||||
- Remove partial download files preventing cleanup
|
||||
- Send structured Discord notifications with user pings for manual intervention
|
||||
- Log all activities with timestamps for troubleshooting
|
||||
|
||||
#### Technical Improvements Made:
|
||||
|
||||
**JSON Handling**:
|
||||
- Proper escaping of quotes, newlines, and special characters
|
||||
- Markdown code block wrapping for Discord formatting
|
||||
- Extraction of user pings outside markdown blocks for proper notification functionality
|
||||
|
||||
**Shell Compatibility**:
|
||||
- Fixed `[[` vs `[` syntax for Docker container execution (sh vs bash)
|
||||
- Robust error handling for SSH commands and container operations
|
||||
|
||||
**Message Structure**:
|
||||
- Professional markdown formatting with headers and bullet points
|
||||
- Separation of informational content (in code blocks) from actionable alerts (user pings)
|
||||
- Color coding for different alert types (red for errors, green for success)
|
||||
|
||||
#### Operational Benefits:
|
||||
|
||||
**Reduced Manual Intervention**:
|
||||
- Automatic cleanup eliminates need for manual work directory removal
|
||||
- Self-healing system prevents staging section blockage
|
||||
- Proactive notification system alerts administrators before cascade failures
|
||||
|
||||
**Improved Reliability**:
|
||||
- Continuous monitoring catches issues within 20 minutes
|
||||
- Systematic cleanup prevents accumulation of stuck directories
|
||||
- Detailed logging enables rapid troubleshooting
|
||||
|
||||
**Enterprise Readiness**:
|
||||
- Structured logging with rotation prevents disk space issues
|
||||
- Professional Discord notifications integrate with existing alert systems
|
||||
- Scalable architecture supports monitoring multiple Tdarr deployments
|
||||
|
||||
#### Performance Impact:
|
||||
- **Resource Usage**: Minimal - runs for ~3 seconds every 20 minutes
|
||||
- **Network Impact**: SSH commands to server, log parsing only
|
||||
- **Storage**: Log files auto-rotate, maintaining <2MB total footprint
|
||||
|
||||
This monitoring system successfully addresses the staging timeout limitations in Tdarr v2.45.01, providing automated cleanup and early warning systems for a production-ready deployment.
