The MultiPing app tracks--you guessed it--device responses to ping. This is a real-time display of traffic, not designed for historical performance plotting. Thresholds are set to measure packet loss, error rates and response times, and minimum/maximum/average and current values are presented in a compact display showing a configurable number of samples over time.
We changed the rate of pinging as well as the size of the ping packet. Alerting is based on simple response times and packet loss percentages. Warning (yellow) and critical (red) graphed responses notified us of threshold violations, corresponding to user-defined thresholds for each. We could run multiple instances of MultiPing to monitor different sets of devices, and we could save monitoring attributes, which was handy.
PingPlotter, a companion product, can be contextually launched from MultiPing or run separately. Also simple in design, PingPlotter runs a traceroute to a target, plotting the minimum/maximum/average results over a configurable number of samples at a user-selected rate. Additional knobs let us save results over time in incremented files, so historical trends can be captured. We could set multiple alerts to be sent by e-mail, system tray icon change, logging and executable notifications.
