How I Used CheckItOn.Us to Monitor my Internal Services
A technical tutorial demonstrating how to create custom monitoring scripts for database replication health.
When I built CheckItOn.Us, I wanted it to be flexible enough to monitor more than just website uptime. Here's how I used it to monitor my internal database replication.
The key was creating custom monitoring scripts that could check specific health metrics without installing additional software on the servers being monitored.
By exposing simple health check endpoints, I could:
- Monitor database replication lag
- Check queue depths
- Verify backup completion
- Track disk space usage
The beauty of this approach is that it works with any infrastructure - cloud, on-premise, or hybrid. If you can expose an HTTP endpoint, you can monitor it.
