A MikroTik health check you can do in two minutes

CPU, memory, uptime, interfaces, and disk — five signals that tell you whether a router is healthy or about to make headlines.

The five-minute watchlist

Start with what the router reports about itself: CPU load, memory use, uptime, interface state, and storage. Uptime is the most human of them — a router that rebooted last night tells you more than a slow trend line, because a reboot is an event with a time and, usually, a cause.

Interface state catches the failures that subscribers feel first: a port that is up but flapping, traffic on an interface that should be idle, or one interface carrying far more than it should. These are visible long before anyone files a ticket.

Watch capacity, not just health

A healthy router can still be the bottleneck. Compare throughput against the link it serves and watch the trend, not the peak: saturation at the same hour every evening is a pricing and shaping conversation; saturation that grows week over week is a capacity one.

Track address table size and DHCP pool usage as well. Both fail in ways that look like 'the internet is down' from the subscriber's side while every individual process on the router is still reporting green.

Configuration backups and change history

The second part of monitoring is knowing what the router was configured to do. A scheduled configuration backup means a replaced device is a hardware swap instead of an afternoon of reconstruction, and a bad change is a diff instead of a mystery.

Keep the backups somewhere the router itself cannot wipe them, and treat a router whose configuration has changed without a matching change record as an incident, not a curiosity.
