    Prints outage statistics from ping output
Usage

ping 8.8.8.8 | ts '%s' | ./outageReport.rb
Examples:

Packet loss

Obviously, packet loss constitutes an outage, but most clients can tolerate a small amount. This script detects when packet loss exceeds the configured time limit before treating it as an outage:

Routing issues

Same as above. If ping doesn't see a timely response within the configured time limit, an outage is recorded.

Ping delays

Sometimes packets don't need to be lost to cause problems for network clients. This script detects when ping has gone quiet for longer than the configured time limit and treats it as an outage, even if all the packets are ultimately returned:
