Manter a conectividade estável é essencial para qualquer infraestrutura de TI. Para garantir isso, desenvolvi um script Bash que executa testes automáticos com MTR (My Traceroute), analisando latência e perdas de pacotes a cada 15 segundos e registrando tudo em um log!
✅ O que esse script faz?
🔹 Monitora a rota até um destino IP/Domínio.
🔹 Identifica saltos instáveis e perda de pacotes.
🔹 Gera logs automáticos para análise posterior.
🔹 Executa testes continuamente a cada 15 segundos.
🛠️ Como Usar?
1️⃣ Instale o MTR no Linux:
sudo apt update && sudo apt install mtr -y Ubuntu/Debian sudo yum install mtr -y CentOS/RHEL
2️⃣ Baixe o Script no GitHub:
git clone https://github.com/felipebrasilio/monitoramento-mtr.git cd monitoramento-mtr
3️⃣ Torne o Script Executável:
chmod +x monitor_mtr.sh
4️⃣ Execute o Monitoramento:
./monitor_mtr.sh

You Should Know:
1. Understanding MTR (My Traceroute)
MTR combines `traceroute` and `ping` to provide real-time network diagnostics. Key flags:
mtr -r -c 10 google.com Send 10 reports and stop mtr --report-wide -c 50 8.8.8.8 Wide output for 50 packets
2. Automating Log Analysis with Bash
Extend the script to parse logs for anomalies:
grep "Loss%" mtr_log.txt | awk '{if ($3 > 10) print "High packet loss at: "$1}'
3. Scheduling with Cron
Run the script periodically via `cron`:
crontab -e /30 /path/to/monitor_mtr.sh >> /var/log/mtr_monitor.log
4. Alternative Tools
- PingPlotter: Graphical traceroute for Windows.
- SmokePing: Latency monitoring with alerts.
- Netdata: Real-time network dashboard.
5. Network Debugging Commands
ip route show Check routing table ss -tulnp List active connections (modern netstat) tcptrack -i eth0 Monitor TCP traffic nmap -sn 192.168.1.0/24 Ping sweep a subnet
What Undercode Say:
Continuous network monitoring is critical for identifying bottlenecks, ISP issues, or cyberattacks. MTR provides granular insights, but combining it with tools like `iftop` (bandwidth monitoring) or `Wireshark` (packet analysis) enhances visibility. For enterprises, integrate with SIEMs like Graylog or ELK Stack for centralized logging. Always validate scripts from GitHub before execution (less monitor_mtr.sh).
Pro Tip: Use `jq` to parse JSON logs if the script outputs structured data:
cat mtr_log.json | jq '.report.hubs[] | select(.LossPct > 5)'
Expected Output:
Start time: 2025-03-31 10:00:00 Target: google.com Hop IP Loss% Avg Latency 1 192.168.1.1 0% 2.1ms 2 10.10.10.1 5% 15.3ms ...
