Frequently Asked Questions
What is NagMon?
NagMon is a Nagios monitoring client for iOS. It connects to your existing Nagios infrastructure and delivers live host and service status, alert history, and an at-a-glance dashboard — an alternative to the Nagios web interface, tailored to iPhone and iPad and built for system administrators on the move.
Can I monitor more than one Nagios server?
Yes. NagMon supports multiple servers, so you can monitor several Nagios instances from a single app and switch between them easily.
How do alerts work?
Alerting stays your Nagios server's job — it keeps sending notifications (typically email) exactly as you've configured it. NagMon is where you go next: open it to see the alert history, the full scope of the problem, and the live plugin output, then acknowledge or schedule downtime right from your phone. NagMon does not send push notifications.
Is the connection to my server secure?
Yes. NagMon connects to your Nagios instance over HTTPS with customizable endpoint settings, so it fits how your infrastructure is set up.
Does NagMon collect any of my data?
No. NagMon collects no data at all — no ads, no analytics, no tracking. Everything related to your use of the app stays on your device.
