AltPing Docs

1. Press A to add a host. Type a name or an IP address.
2. The app pings every host once per second. You can change it for each host.
3. Press D to see the history chart of the selected host.

To add many hosts at once, put them in the Host field and separate them with commas or spaces: 8.8.8.8, 1.1.1.1 example.com

For each host you can also set:

• TCP port: some servers do not answer ping. Check "Check instead of ping" and enter a port, for example 443. The app then connects to this port and shows how long it takes.
• Ping every: how often to ping. 1000 ms by default.
• Timeout: how long to wait for a reply. 1000 ms by default.
• Slow above: show the host in yellow when its average time is above this number. 0 is off.
• Notify: beep when the host goes down or comes back. Down means 3 failed pings in a row. The window title shows how many of these hosts are down, for example "(2 down)".

You can turn on more columns in Settings:

Click a column title to sort the table. Click again to sort in the other direction.

• Green: the host replies.
• Yellow: the host is slow (if you set "Slow above" for it).
• Orange: the last ping failed.
• Gray: no pings yet.

• Select one or more hosts (up to 4) to see them on the chart.
• Buttons 5m, 1h and 24h change the time range.
• Red striped areas mean there was no reply.
• A break in the line means pinging was stopped.
• Mouse wheel: zoom. Drag: move. Double-click: zoom out.
• Drag the line between the table and the chart to change their size.

The app keeps 24 hours of history. It is saved on disk, so it is still there after a restart.

You can have many host lists, for example "Home" and "Office". Press O to open the list window:

• New makes an empty list.
• Save As makes a copy of the open list.
• Remove deletes a list. You cannot delete the open list.
• Double-click a list or press OK to open it.

• Edit and Remove the host.
• Downtime shows when the host did not reply in the last 24 hours, and for how long.
• Export history saves the last 24 hours of pings to a CSV file. You can open it in Excel.
• Change selected changes all selected hosts at once: turn the beep on or off, check a TCP port or go back to ping, set Ping every, Timeout or Slow above.

Click Settings at the bottom of the window. Everything here is off by default.

• Extra columns: Min, Jitter and Since.
• Always on top: keep the window above other windows.

• The status bar shows the ping mode. Without admin rights on Linux and macOS the app uses UDP mode. It works the same way.
• IPv4 and IPv6 are supported. If a name has both, IPv4 is used.
• Settings, lists and history are in the .altbins/.altping folder in your home folder.
• The app remembers the window size and the chart panel.
