# System Log Paths Reference
## Complete mapping of all log files across all supported platforms
**Generated from**: `lib/log-paths.sh`
**Last Updated**: 2026-03-20
---
## Overview
All scripts should reference log paths via environment variables set during system detection. These variables are automatically derived based on the detected:
- Control panel (cPanel, Plesk, InterWorx, Standalone)
- Operating System (RHEL/CentOS/AlmaLinux vs Ubuntu/Debian)
- Services installed (Apache, Nginx, MySQL, Exim, etc.)

if [ -n "$SYS_LOG_WEB_DOMAIN_ACCESS" ]; then
grep "404" "$SYS_LOG_WEB_DOMAIN_ACCESS"/*
fi
# OR access main logs (all platforms)
tail -f "$SYS_LOG_WEB_ACCESS"
```
### Example 2: Check Auth Logs
```bash
#!/bin/bash
source lib/system-variables.sh
# Works on both Ubuntu and RHEL
grep "Failed password" "$SYS_LOG_AUTH"
```
### Example 3: Check Mail Queue
```bash
#!/bin/bash
source lib/system-variables.sh
# Check mail system queue (works for all mail systems)
exim -bpc # If Exim
postqueue -p # If Postfix
```
### Example 4: Monitor Firewall
```bash
#!/bin/bash
source lib/system-variables.sh
# Watch firewall blocks
tail -f "$SYS_LOG_FIREWALL"
```

## Notes
1. **All paths are automatically derived** during system detection
2. **No scripts should hardcode paths** - always use SYS_LOG_* variables
3. **Mail system detection** identifies Exim, Postfix, or Sendmail and sets appropriate paths
4. **Control panel detection** sets panel-specific log directories
5. **OS detection** handles RHEL vs Debian differences (secure vs auth.log, messages vs syslog)
---
## Updating This Reference
When adding support for a new service or changing paths:
1. Update `lib/log-paths.sh` with the new detection logic
2. Add a `derive_<service>_logs()` function
3. Call it from `derive_all_log_paths()`
4. Document the mapping here
5. Update any scripts that reference those logs
