ping+chart

Ping statistics in ASCII chart.

Basic Usage

Create servers.lst like:

192.168.1.1
1.234.56.78
8.8.8.8
1.2.3.4

Plot realtime ping chart of packet loss statistics (the default metric):

bash ping+chart.sh

Available metrics:

• sent - packets sent
• receive - packets received
• loss (default) - % packet loss
• avg - average RTT value in millisecond
• min - minumum RTT value
• max - maximum RTT value
• stddev - standard deviation on RTT

E.g, plot average network latency statistics:

bash chart+ping.sh avg

NOTE It can take seconds to generate a single chart.

chart.sh

The chart.sh is a bash implementation of ASCII chart inspired by asciichart with additional features:

• Multiple data series
• Color scheme (built-in dark/light theme and 256 color support)
• Non-continuous data series support
• Legend box (can be turn off by NO_LEGEND=1 flag)

Advanced Usage

Multiple Chart Display

Collect ping statistics in separate process:

bash ping.sh | tee ping.log

Plot chart continously:

bash ping+chart.sh -f ping.log [other chart options]

Snapshot

Export chart script:

bash ping+chart.sh -q -r > loss-chart.cs

Plot chart from snapshot:

bash chart.sh < loss-chart.cs

Todos

• better performance
• Y-axis auto down scale (too slow)
• chart legend display
• tweak color scheme
