Performance Alerting Rules

# Prometheus alerting rules
groups:
- name: fivem_alerts
  rules:
  - alert: HighCPUUsage
    expr: cpu_usage > 80
    for: 5m

Migration and Deployment Strategies

Linux-to-Windows Migration

# Data migration script
#!/bin/bash
SOURCE_DIR="/home/fivem/server"
DEST_SERVER="windows-server.local"
DEST_PATH="C:\\FiveM\\"

# Sync server files
rsync -avz --progress "$SOURCE_DIR/" administrator@"$DEST_SERVER":"$DEST_PATH"

# Configuration conversion
sed -i 's|/home/fivem/server/|C:\\FiveM\\|g' server.cfg
sed -i 's|/|\\|g' server.cfg

echo "Migration preparation complete. Manual testing required."

Docker Containerization Strategy

# Multi-stage FiveM container
FROM ubuntu:22.04 AS builder
RUN apt-get update && apt-get install -y curl xz-utils
RUN curl -sSL https://runtime.fivem.net/artifacts/fivem/build_proot_linux/master/ \
    -o /tmp/fx.tar.xz && tar -xf /tmp/fx.tar.xz -C /opt/

FROM ubuntu:22.04
COPY --from=builder /opt/fivem /opt/fivem
EXPOSE 30120/tcp 30120/udp
VOLUME ["/opt/fivem/server-data"]
CMD ["/opt/fivem/FXServer", "+exec", "server.cfg"]

Troubleshooting: Common Issues and Solutions

Linux Performance Issues

High Memory Usage:

# Memory leak detection
valgrind --tool=memcheck --leak-check=full --track-origins=yes \
         /home/fivem/server/FXServer +exec server.cfg

# Emergency memory cleanup
echo 3 > /proc/sys/vm/drop_caches
systemctl restart fivem.service

Network Connectivity Problems:

# Network diagnostic suite
ss -tuln | grep 30120
iptables -L -n -v | grep 30120
tcpdump -i any port 30120 -c 100

# Reset network stack
systemctl restart systemd-networkd
systemctl restart systemd-resolved

Windows Troubleshooting

Service Startup Failures:

# Event log analysis
Get-WinEvent -LogName System | Where-Object {$_.Id -eq 7034} | Select-Object -First 5

# Dependency check
sc query FiveMServer
Get-Service -Name "FiveMServer" | Select-Object *

Performance Degradation:

# Performance counter monitoring
Get-Counter "\Process(FXServer)\% Processor Time" -Continuous
Get-Counter "\Process(FXServer)\Working Set" -Continuous

# Memory dump analysis
tasklist /m | findstr FXServer.exe
