Network Watch
Monitoring for ~100 devices — OLTs, ONUs, MikroTik routers and switch ports — with Telegram alerts.
The problem
Checking around a hundred network devices by hand — OLTs, ONUs, routers, switch ports — doesn't scale.
What I built
- Monitoring with LibreNMS and Zabbix over SNMP.
- Alerts pushed to Telegram, so problems reach a phone immediately.
The hard part
- Covering many different device types and keeping alerts useful instead of noisy.
Result
One dashboard and instant alerts instead of logging into every device.
