PacketTrends keeps an eye on the hosts and services you care about and alerts you the moment something breaks. Connect the app to your PacketTrends workspace to see your whole fleet at a glance — every monitored host, colour-coded by health, with latency and packet loss right there. • ICMP ping checks — reachability, round-trip latency, jitter, and packet loss • TCP port checks — handshake success, time-to-connect, and timeout/refused rates for any port (443, 22, 8089, and more) • One host, many checks — track a server's ping plus several ports independently • Per-host history — latency and connect-time trends over minutes, hours, and days • Push alerts — get notified instantly when a host goes down, and again when it recovers • Manage on the go — add, edit, and remove hosts and toggle alerts from your phone No account?
