ping RTT and packet loss script

[kurowsky]

Yeah, I didn't really explain my problem well.
When I run the script manually it works perfectly.

I created a data input method, which all seems correct:
-script/command
-correct path: perl <path_cacti>/scripts/rtt.pl <count> <host>
- two input fields: count and host
-four output fields: min, avg, max and loss

My data template seems correct:
-data input method is correct
-have four data source items corresponding to the above output fields

I believe my graph template is correct too.
I applied the graph template to the host template (cisco router)

I create the graph, and after five minutes debug says it's okay but no data is being displayed (-1.#J) which I know is okay at first.
Wait 10 to 15 minutes and still nothing.
So I checked the rra file and the rrd for this item has been created but not updated.

It's the only one out of 504 that is not being updated.
I don't understand what I may be missing. It should be getting updated even if I'm sending wrong data or no data.( I think )

It is the only script that I'm running though.

Does that help?

maybe you can try to run php.exe c:\inetpub\wwwroot\cacti\cmd.php at the dos command so you can see what values the script is returning. If it says:

Code: Select all

MULTI command: perl c:\apache\htdocs\cacti/scripts/pingavg.pl 195.130.130.4 2, output: min:93 avg:138 max:183 loss:0
MULTI expansion: found fieldid: 37, found rrdname: min, value: 93
MULTI expansion: found fieldid: 38, found rrdname: avg, value: 138
MULTI expansion: found fieldid: 39, found rrdname: max, value: 183
MULTI expansion: found fieldid: 40, found rrdname: loss, value: 0
update c:\Apache\htdocs\cacti/rra/localhost_loss_20.rrd --template min:avg:max:loss N:93:138:183:0

you know the problem must be at the graph template or something else

Maybe try: rrdtool fetch yourdb.rdd AVERAGE and see the output

what I cannot figure out is that on Redhat 9 the last line of ping stats are in the form of:

4 packets transmitted, 4 received, 0% packet loss, time 3006ms
rtt min/avg/max/mdev = 0.442/0.450/0.467/0.018 ms

This causes NONE of the scripts to work, since looking for a value next to min, avg, etc.. does not produce any results. The loss works because it is next to the percent sign...

Am I missing something?

[dieter]

you have to change the regular expression to look for the slashes /

Their seems to be a few windows scripts here. I can get mine to work when I run it via comamnd line, but i cant get it to graph??

How do I do it??

#!/usr/bin/perl

$host = $ARGV[1];
$pingcount = $ARGV[0];

$ping = `ping -n $pingcount $host`;

# starts some variables

$min;
$max;
$avg;
$loss;

# check for the minimum value

$ping =~ /Minimum = (\d*)/;
$min = $1;

# check for the maximum value

$ping =~ /Maximum = (.*)ms,/;
$max = $1;

# check for the average value

$ping =~ /(Averag|Gemiddeld)e = (.*)ms/;
$avg = $2;

# check for the % sign inside parens and grab it's value
$ping =~ /(\d*)%/;
$loss = $1;

#print the values
print "min:$min avg:$avg";

Could someone post their working copy of the script and any templates known to work on Windows?

That would be greatly appreciated!!!!

Here is the one i use:
.....
use it like your script: latence.pl <count> <host>
and it return somethink like:

Code: Select all

min:10.766 avg:17.067 max:60.479 dev:14.497 loss:0

....
thx to my friend TiChou for helping :)

Hi. I want to make this skript work, so when I run at console i see it working. But i read some howto's and do not understand some things ^(. Can someone tell me please what should i do step by step to run any script i wrote on this example with ping?

Thank you!

P.S.sorry, it was my last post

I can add new method in "Data Input Methods" with my own script or this one. But i see it is not enough. Is it possible to make new graph with this script (or any script) without adding new query in "Data Queries"?

[Altex]

Please help me? I can easily write my own script but i can't make it work with cacti, because i do not well understand that to do exactly. Can you show me just one example?

Thank you, i hope you find some minutes to tell me or just give me a link to another article.
