<font face="Bitstream Vera Sans Mono">Hey folks,<br>
<br>
Our network group is looking to get some more performance from
smokeping. </font><font face="Bitstream Vera Sans Mono">I'm looking
for some tips on how to optimize performance and I welcome any
suggestions. </font><font face="Bitstream Vera Sans Mono">Currently,
we have about 6400 ip addresses that are pinged 30 times across a 5
minute interval. When I reconfigured smokeping last time, I set up 30
FPing probes and distributed the ip addresses across those 30. Right
now, there is no offset on those FPing probes, but I have experimented
with that in the past. We are consistently adding branches, which means
more ip addresses to ping, so I have a script that runs every morning
to retrieve the latest list of ip addresses from a database and write
the config for smokeping. Many of our branches are on DSL or cable with
some dialup, but many are moving to T1. My feeling is that some
smokeping performance issues may be solved simply by having lower
latency links. Our network group would like to be able to do 5 pings
every 30 seconds for each of the 6400+ ip addresses. As part of the
process of improving performance, we are going to move smokeping from a
virtual machine to a physical machine. However, we are currently
running it in Xen paravirtualized, so <br>
<br>
Are any folks on this list doing a similar number of pings in a fairly
short amount of time? Is there a better way to spread out the ping load
other than creating more FPing probes? We seem to be limited by I/O and
memory and those probes currently use about 3.5 GB of memory last time
I checked. Another thought we had was to use SAN disk instead of
internal disk to decrease latency and improve throughput.<br>
<br>
Also, I just wanted to say thanks to all of the developers and testers
of smokeping for a great utility. We have been using it for over 2
years now and have been pleased with its reliability and performance.
We looked at comparable commercial solutions that could match the
performance that we get from smokeping and were shocked at their
sticker price.<br>
<br>
Let me know if you need more details about our setup. Thanks in advance.<br>
<br>
