# Plugin to monitor packet loss
|
||
|
|
#
|
||
|
|
# Please note that sometimes it can take quite long for the plugin to return
|
||
|
|
# a value on a network with lots of packet loss.
|
||
|
|
# You therefore need to account for it by appending the following to your
|
||
|
|
# plugin-conf.d/munin-node. Remember to restart munin-node afterwards.
|
||
|
|
# Append the next 3 lines to plugin-conf.d/munin-node:
|
||
|
|
# [packetloss_*]
|
||
|
|
# timeout 60
|
||
|
|
# user root
|
||
|
|
#
|
||
|
|
# Parameters:
|
||
|
|
#
|
||
|
|
# ping_args - Arguments to ping (default "-c 2")
|
||
|
|
# 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
