Odoo Server Monitoring & Uptime: Complete Guide

Why Monitor Odoo?

Without monitoring, you discover problems when users complain. With monitoring, you discover problems before users notice. Odoo servers can fail silently: memory leaks, disk filling up, stuck crons, database bloat — all preventable with proper monitoring.

What to Monitor

Method 1: Simple Monitoring (Free)

Uptime Check with curl

#!/bin/bash
# /opt/scripts/health-check.sh
HTTP_CODE=$(curl -s -o /dev/null -w "%{http_code}" http://localhost:8069/web/health)

if [ "$HTTP_CODE" != "200" ]; then
    echo "[$(date)] Odoo DOWN! HTTP $HTTP_CODE" >> /var/log/odoo-health.log
    # Send alert (email, Slack, PagerDuty)
    curl -X POST "$SLACK_WEBHOOK" \
        -d '{"text":"🔴 Odoo is DOWN! HTTP '"$HTTP_CODE"'"}'
    # Try restart
    systemctl restart odoo
fi

# Cron: every 5 minutes
# */5 * * * * /opt/scripts/health-check.sh

Disk & Memory Alerts

#!/bin/bash
# /opt/scripts/resource-check.sh
DISK_USAGE=$(df -h / | awk 'NR==2 {print $5}' | tr -d '%')
MEM_USAGE=$(free | awk '/Mem:/ {printf("%.0f", $3/$2 * 100)}')

if [ "$DISK_USAGE" -gt 85 ]; then
    curl -X POST "$SLACK_WEBHOOK" \
        -d '{"text":"⚠️ Disk usage at '"$DISK_USAGE"'%"}'
fi

if [ "$MEM_USAGE" -gt 90 ]; then
    curl -X POST "$SLACK_WEBHOOK" \
        -d '{"text":"⚠️ Memory usage at '"$MEM_USAGE"'%"}'
fi

Method 2: UptimeRobot (Free Tier)

# UptimeRobot.com — free for 50 monitors
# Add monitor:
# URL: https://your-odoo.com/web/health
# Type: HTTP
# Interval: 5 minutes
# Alert contacts: email, Slack, PagerDuty

# Also monitor:
# - SSL certificate expiry
# - Keyword check (response contains "ok")

Method 3: Prometheus + Grafana (Production)

# For serious production monitoring:

# Install node_exporter on Odoo server:
wget https://github.com/prometheus/node_exporter/releases/download/v1.7.0/node_exporter-1.7.0.linux-amd64.tar.gz
tar xzf node_exporter-*.tar.gz
sudo mv node_exporter-*/node_exporter /usr/local/bin/

# node_exporter as systemd service:
# Exposes: CPU, memory, disk, network metrics
# Prometheus scrapes these metrics
# Grafana visualizes with dashboards

# PostgreSQL exporter:
# Monitors: connections, query times, table sizes, locks

# Alertmanager rules:
# - OdooDown: probe_success == 0 for 5m
# - HighCPU: cpu_usage > 90% for 10m
# - DiskFull: disk_usage > 90%
# - PostgresConnections: connections > 80% max

Method 4: Cloud Provider Monitoring

# Most cloud providers include basic monitoring:

# DigitalOcean: built-in CPU, memory, disk, bandwidth
# AWS CloudWatch: EC2 + RDS metrics
# Hetzner: Cloud Console metrics
# Vultr: built-in monitoring
# GCP: Cloud Monitoring

# Set up alerts at:
# CPU > 80% for 10 minutes
# Disk > 85%
# Memory > 90%

Log-Based Monitoring

# Monitor Odoo logs for errors:
# Approach 1: Simple grep + alert
tail -F /var/log/odoo/odoo.log | grep --line-buffered -i "error\|critical\|killed" | while read line; do
    curl -X POST "$SLACK_WEBHOOK" -d "{\"text\":\"🔴 Odoo error: $line\"}"
done

# Approach 2: Fail2ban for security
# Monitor /var/log/odoo/odoo.log for repeated login failures
# Auto-block IPs with too many failed attempts

Monitoring Checklist

1. HTTP health check every 5 minutes
2. SSL certificate expiry alert (30 days before)
3. Disk usage alert at 80%
4. Memory usage alert at 85%
5. CPU sustained high alert at 80% for 10min
6. PostgreSQL connection count monitoring
7. Backup success verification daily
8. Cron health check (lastcall freshness)
9. Log monitoring for errors and security events
10. Uptime dashboard for stakeholders
