Re: Smokeping Problem


Hi,
I can't make IOSPing work ... is there any example config file??? Sorry
but I cannot udrestand the given help  in support section:

 *** Probes ***
 + IOSPing
 binary = /usr/bin/remsh
 packetsize = 1024
 forks = 1

 ++ PROBE_CONF
 ioshost = router
 iosuser = user

Here is section *** Probes *** in my config file:

*** Probes ***

+ FPing
binary = /usr/local/sbin/fping

+ IOSPing
binary = /usr/bin/rsh
packetsize = 1024
forks = 1

ioshost = router.domain.net
iosuser = user

Re: Smokeping Problem


I had similar problems. I use both FPing and IOSPing in my config. I set
it up like this:

My probes section:
*** Probes ***

+ FPing
binary = /usr/local/sbin/fping

+ IOSPing
binary = /usr/bin/rsh
packetsize = 1024
forks = 1

Part of my Targets section:

probe = IOSPing

+ AggregationPoints
probe = IOSPing
menu = Aggregation Points
title = Aggregation Points

++ FromFTL
menu = from-ftl
title = ATM Latency from Fort Logan

+++ PROBE_CONF
ioshost = 10.11.12.13

Re: Smokeping Problem


I forgot to mention that I had to make a small modification to IOSPing.pm
because on one router in particular it was just too darn fast and the
connection was closing before the router woke up enough to respond. I
added a 1 second sleep before it started sending stuff to the router.

    my $pid = open2($outh,$inh, <at> args);
    #
    # The following comments are the dialog produced by
    # "remsh <router> ping" to a Cisco 800 series running IOS 12.2T
    #
    # Other hardware or versions of IOS may need adjustments here.
    #
    # Protocol [ip]:
--> system("/bin/sleep 1");
    print { $inh } "\n";
    # Target IP address:
    print { $inh } $target->{addr},"\n";

IPv6 and resolve!


Hi,

Can anyone tell me how smokeping resolves IPv6 hostnamens?

I have configures IPv6 in smokeping and it works fine, except one thing...
When (re)starting smokeping i always get an error it can't resolve the IPv6
hostname... but when i use (f)ping6 or host tools they resolve just fine...
I also see the errors sometimes when opening my smokeping webpage...

http://stats.cvee.org/smokeping.cgi

Thx to anyone who can help me with this... it is not a major problem... just
wondering how smokeping handles this stuff ;-)

Greetz,

Cristian van Ee.

Re: Premature end of Script headers


I am getting the same error , with an access denied message. I am pretty sure that I have the privs set
correctly since I have this in a directory with other cgi scripts running correctly.  I am running Nagios
for notifications and MRTG with 14all for trending. Any help would be appreciated.

Thanks

Ray

Daily Status e-mail

I've got Smokeping running and watching my network for me.

However, the only way to view the data is to VPN into my local network
and watch the web pages.

The alerts feature is GREAT in that alerts mail me when something is
up/down/slow. I would like to expand on this feature and have Smokeping
mail me an overnight daily summary of the graphs. This would be helpful
in knowing, for example, the kind of day I'll be facing in the morning!

Has anyone any good ideas on how to do that, or has anyone done that
already?

Thanks!

Dan

Re: Daily Status e-mail


Dan,

I do this very thing.  This has been something I was going to suggest to 
Tobi for Smokeping.  Here is what I do.  Everytime an alert comes 
through I send an email alert out to the Operations Center and to WAN 
Engineers.  The same mailing script also concatinates all the messages 
for a day into a file which I process the next day.  The next day I 
create a real, honest to goodness Excel spreadsheet to the same audience 
of the prior day's activities.  It is pretty darn simple to do, and best 
of all I send said data in an Excel spreadsheet.  Since the data is in 
Excel it looks very polished, professional and the suits believe it a 
whole lot more than if I only sent the data in a text file.  At the 
conclusion of the month I send a prior month summary to everyone.  

Here is what you need.  There are two Perl modules you need to install 
on your system to create Excel Spread sheets. Then creation and mailing 
of the data is trivial.

Regards,
Jim

Clearing extreme points in graphs?


Hi,

Hopefully this is doable.  I have about 6 months worth of data for my 
graphs.  Typical RTT is alway 10 - 20 ms.  During this past weekends 
sql/slapper fiasco, I've got this huge spike in the graphs, up around 
2000+ms, that lasts for a couple of hours.  As expected.

This has the unfortunate side-effect of skewing the graphs on my longer 
range charts.  e.g., on a 60 day chart, it appears that ping time are 
0.0 (a flat green line along the bottom edge), up til last Saturday.  Is 
there any way to clear out these extreme entries?  Short of wiping out 
the .rrd files and starting fresh?

Hope this makes sense.  :-)

The Cricket folks have excellent spike-removal technology (now, if we
could only prevent the damn spikes from happening in the first place).
Please see the Cricket contrib page at:

   http://www.certaintysolutions.com/tech-advice/cricket-contrib/

You'll be interested in these two programs:

    killspike2 (by Matt Zimmerman) - removes entries in a DS that
exceed a specified value.

    rrdcut (by yours truly) - removes all entries in the RRD file
between a specified date and time.

I've used both of these scripts for Cricket RRD files, I'm not
familiar with the construction of a Smokeping RRD, but these
scripts have no Cricket-specific stuff in them so they might
work for you.  Suggest you set up a test copy of an RRD and
experiment with it.
