+#!/bin/bash
+# This script is intended for use with Munin to monitor
+# network interface uptime. Usually this would be ppp0 or smth.
+# Tested under Ubuntu Gutsy.
+# v. 1.00, 12/15/2007

+#
+# The plugin can utilize automatic configuration,
+# here are the basic steps (require root privileges):
+# 1. Copy it as /usr/share/munin/plugins/if_uptime
+# 2. Customize interfaces to monitor
+# 3. Make executable: "chmod 755 /usr/share/munin/plugins/if_uptime"
+# 4. Run "munin-node-configure --shell", you should see smth like
+# "ln -s /usr/share/munin/plugins/if_uptime /etc/munin/plugins/if_uptime"
+# Multiple interface monitoring is supported as well. Customize below.
+# 5. Run the proposed command to create a link.
+# 6. To verify, run "munin-node-configure", you should notice the "if_uptime" record
+#

+# if_uptime                  | yes  | 
+#
+# 7. Restart munin: "/etc/init.d/munin-node restart"
+# 8. Hold on for 5 minutes at most and watch the graph appear.
