Nagios seeing some devices as unreachable or down

[mike.brickles]

Hi Nagios

seems to be going something odd.

Some devices are showing down or unreachable put I can ping them fine.

This is for some desktop computers and printers its ever unreachable or down but they not.

Can you please provide more detail?

• When the devices are down or unreachable, what is the actual status output?
• Is this for all devices or just some?
• Can you provide the config definitions for these failing checks?
