Pingback is a network latency monitor built in Go. It displays latency as a scrolling heatmap, providing a visual representation of network performance & reliability.
go buildPingback is only known to work on linux. It might work on MacOS and will not work on Windows without modification. Refer to these instructions for more information. On Linux, you need to set the following:
sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"Then you can run Pingback like this:
pingback -address=<IP_or_URL> [-delay=<milliseconds>] [-group=<groupSize>] [-aggregates=<number>]Options:
-address: The IP or URL to ping.-delay: Time between pings in milliseconds (default is 1000ms).-group: Number of samples to aggregate together (default is 32).-aggregates: Number of aggregate charts to show (default is 2).
To ping example.com every 500 milliseconds, use:
pingback -address=example.com -delay=500By default, Pingback displays latency data in three charts: one for real-time values, one for mid-term averages, and one for long-term trends. Latency values are represented as colored rectangles, ranging from blue (low latency) to red (high latency). A dark purple X indicates a dropped packet.
Each aggregate chart aggregates -group elements from the previous chart, and displays a statistical overview of them. The overview is a set of evenly spaced order statistics. The number of statistics depends on the log2 of the elements that are to be aggregated.
The upper rows show smaller values than the lower rows.
