Smokeping IPv6 Support

Does Smokeping support IPv6?
 
Thank You,
Jeff Wright

it has not been tested with v6 by me, but since there is no general
ip magic inside, I would imagine fixes to the be limited or even
unnecessary.

I'm using it with IPv6. What is your concern?
Right now I'm monitoring my ipv6 enabled machines (at home) from my
server, both using ping and SMTP.

IPv6 address as target for EchoPingHttp not working


Hi list,

don't know if this is known limitation, but want to bring this to your attention.
I just discovered that one cannot use an IPv6 address as target for
EchoPingHttp. The plug-in gives a warning and the graph is empty:

smokeping 2.003006
echoping 6.0.2

smokeping[8577]: EchoPingHttp: WARNING: "/usr/bin/echoping -p 6 -t 1 -w 1 -6 -h
/ -A -a -R -n 5 2001:db8:x:x:x:x:x:x:80" exited with status 1 - output follows
smokeping[8577]: EchoPingHttp:          getaddrinfo error for host: 2001 Address
family for hostname not supported

Problem is that the plugin automatically appends the port number to the IPv6
address. The result is a not valid IPv6 literal "2001:db8:x:x:x:x:x:x:80".
Embedding the IPv6 address in "[]" helps, as the resulting IPv6 literal with
port appended "[2001:db8:x:x:x:x:x:x]:80" works well with echoping in the shell.
Should be easy for an educated programmer to fix this.

Since this is fixed you should only use FQDN as targets for EchoPingHttp (I
would assume the same is true for EchoPingHttps).

cheers,
Christian

Yeah, I see. Thanks for the report. I'll look at fixing this.

RTT Alerts - In Percentages?

Hello list,

Im curious if I can use percentage operators on the RTT alert type?

For instance, some of my monitored links are less than 15 ms, and should never exceed 60ms, and some links are
100ms and should never exceed 400.  Instead of configuring alert types for each of these varying kinds of
hosts, i'd like to build an alerting pattern that allows me to say:

If rtt increases by 50%, then goes back to normal, then increases by 50% again, raise an alert.  Basically I am
looking for a condition to identify jitter, when i dont know what "normal" RTT is in milliseconds.

Thanks for any input!

Re: RTT Alerts - In Percentages?

Unfortunately, there's no way native to Smokeping that you could do this.  Currently there are exactly 2 ways to trigger alerts:  hardcoded RTT values, and loss percentage.

It would almost certainly be possible to hack this functionality in, though.  If you ever get around to it, I'm sure Tobi would appreciate a patch.  :)

explanations about the calculation of tops of RTT, deviation...

Hi,
As you can notice in the picture the value of Max RTT in the title (value n°1) doesn't match with the maximum value displayed in the line median RTT (figure n°2) .Can you provide me an explanation for this difference, because I don't understand how Smokeping caluclates the figure of maximum RTT , deviation... which are displayed in the titles.
 
I'm also wondering about the meaning of %f that I find in the following script:
 

++ max

sorter = Max(entries=>5)

title = Top Max Roundtrip Time

menu = by Max

format = Max Roundtrip Time %f seconds.

 

Thank you for your help!

1. Have you specified values for either 'sendmail' or 'mailhost' in
your config file?
2. If yes, have you looked in your local mail log (typically
/var/log/maillog) to see if emails are being sent?

hope this helps,
Darren

understanding the overview graph

Hi,

So I hopefully understand the "Detail" graph, how the smoke elegantly 
shows the variation in response times, and why most smoke is above the 
median line.

But I'm struggling to understand the "Overview" (and also Multihost) 
graphs, where there is a coloured area around the main lines.  And unlike 
the Detail graph, this Overview coloured area always seems to be equal in 
height both above and below the line.  I can't see how it relates to the 
smoke info on the Detail graph.

Can anyone tell me what this coloured area in the Overview graph means ?

Sorry for being thick!

Chris
