Opto22 to check Ping Status

Is there any possible applications/script for Opto22 to check if all devices in network can be reach? Pingable?

Yes and No.

It is my understanding that ICMP can not ping a broadcast address space, so in short, no, you can not find them all at once.
What you have to do is set up a timer and increment the address and ping each address in the space.
So starting from x.x.x.1 to x.x.x.254 The result of this ping sweep will be all the hosts that are up.

To directly answer your question, yes, you can do it, start with this sample chart; https://www.opto22.com/support/resources-tools/downloads/pingbasicexample-cxf

EDIT. Talk to your IT guys before you do this, it could look bad from their network monitoring software (if they are using some) and be sure to put a delay in there, so you don’t end up with a ping storm and cause timeouts.
