+# This script is intended for use with Munin to monitor
+# ping response time from hosts and through interfaces specified.

+# The plugin can utilize automatic configuration,
+# here are the basic steps (require root privileges):
+# 1. Copy it as /usr/share/munin/plugins/pinger
+# 2. Make executable: "chmod 755 /usr/share/munin/plugins/pinger"
+# 3. Customize hosts, interfaces and ping count below
+# 4. As pinging takes much time, add a
+# --
+# [pinger]
+# timeout 60
+# --
+# record to /etc/munin/munin-node.conf to avoid timeouts.
+# 5. Run "munin-node-configure --shell", you should see smth like
+# "ln -s /usr/share/munin/plugins/pinger /etc/munin/plugins/pinger"
+# 6. Run the proposed command to create a link.
+# 7. To verify, run "munin-node-configure", you should notice the "pinger" record

+# 8. Restart munin: "/etc/init.d/munin-node restart"
+# 9. Hold on for 5 minutes at most and watch the graphs appear.
