Feature idea summary

Cgroups plugin supports only proportional and max Block IO policies. We should support BFQ scheduler as well. Disk stats for the scheduler are in blkio.bfq.io_service_bytes and blkio.bfq.io_serviced files.

When using right Y-axis, the first (rightmost) legend label is hard to click. Only a small fraction on the left side of the label is actually clickable. Almost impossible to hit on touch devices.

I assume this is due to the negative margin of the parent item (<div class="view" ...>)

Gatus is awesome. There is a way to setup a maintenance window to avoid being notified if a server (or many) goes down?

Has anyone done this safely?

If we can't open port, then lets do something like:

nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
