Package: collectd
Version: 4.10.1-2.1
Severity: minor
Hi.
Collectd's pluging 'ping' currently sends 64 bytes of additional content
in ICMP packets, this gives about 84 octets in size of packets.
On many types of networks sending small packets is not best way to measure
network delay or conectivity. For example in wireless networks,
small packets have much smaller probability of being corrupted,
thus using small ping packets will give as false positive information
about good conectivity, even when in the same time all other traffic
(i.e. TCP) will not work.
So i wanted to use about 1100 bytes packets by default (or 1440
as it is pretty common MTU on ethernet and wifi),
but I cannot do this in collectd currently.
Manual page of collectd.conf does not mention about any
such parameter.
Normal ping utility have parameter '-s packetsize', exactly for this
purpose.
It should be very simple change to add this to the ping plugin.
Expose additional parameter with PacketSize with
values in range 0-65507, allocate bigger buffers, and
initialize them with some simple pattern.
It should be actually be very easy because AFAIK
collectd's ping uses liboping library, and it exposes many
other functionalities.
For example other usefull option is seting "not fragment"
flag in IP packet.
Regards,
Witek
