+# Plugin to monitor ping times
+#
+# Parameters:
+#
+# 	ping_args      - Arguments to ping (default "-c 2 -w 1")
+# 	ping_args2     - Arguments after the host name (required for Solaris)
+# 	ping           - Ping program to use
+# 	host           - Host to ping
+#
+# Arguments for Solaris:
+#      ping_args      -s
+#      ping_args2     56 2
+#
+# Tips for very fast ping replies
+#   (thanks to Alex Davies and Nicolai Langfeldt):
+# Apparently, old versions of munin can't handle scientific notation of values
+# so, if you're getting replies like this from your node:
+# site1.value 5.2e-05
+# and your graph looks like a flat line, remove the -o argument from graph_args
+#
+# Configuration example
+# [multiping]
+# env.hosts www.google.com,www.yahoo.com
+# env.names Google, Yahoo
+# env.ping_args -A -c 5 -w 2
+#
+#%# family=auto
+#%# capabilities=autoconf
