Mac OS Utilities
ICMPUtil is a tool to monitor multiple Hosts network connectivity using ICMP echo requests.
ICMPUtil helps network troubleshooting by graphically displaying response time of multiple hosts simultaneously. If enabled, ICMPUtil can send user notifications when a packet loss or response threshold is reached and additionally email messages to selected mail destinations.
Monitored hosts can be established using IP Network/range discovery or manually specifying IP Addresses or DNS names. Hosts lists can also be saved or loaded from files.
