Windows Ping Script Graph

[dirkvdriel]

Helo,

I hope that some one can help me with the option Ping Lantency Graph. What I try, the Graph is still empty.
What do I have:
- Windows 2003
- IIS
- Latest version of Cacti (0.8.7e) with the patched installed.

RRDTool say that everything is OK.....

RRDTool Command:

c:/rrdtool/rrdtool.exe graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="cactiserver - Ping Latency" \

Other graph works fine I have only a problem with this item, I have look in this form but al the other options gives the same results.

If you need more information, please let me know.....

CMDPHP: Poller[0] Host[3] DS[17] CMD: perl C:/Inetpub/wwwroot/cacti/scripts/ping.pl 127.0.0.1, output: U 

Thats your problem. Fix that so it spits out data and then you'll get some nice graphs.

[dirkvdriel]

I was also thinking that this is the problem, but I can't see whats wrong.

Well for starters, what happens when you manually run that command?

[leoh]

I am facing the same problem here.

WHen I run the command in command line, I get:

Code: Select all

perl /opt/cacti-0.8.7e/scripts/ping.pl 10.235.1.1
973

Logs show:

Code: Select all

SCRIPT: perl /opt/cacti-0.8.7e/scripts/ping.pl 10.235.1.1, output:
U

The graph is most of time empty, but eventually I see a line plotted. And than it stops plotting again.
I have increased ping timeout to 5s in cacti configuration. I did the same in the device configuration.

What is wrong with this ping latency test?

[BSOD2600]

Linux question on a windows forum...

Anyways, as the device timeout doesn't get passed onto the script, it must have it's own internal timeout (I dont have the code in front of me). My guess is that the device's high latency is causing the script to prematurely time out.

Using spine or cmd.php?

SPINE

The ping is taking no more than 1s to return (1000ms).

I am facing the same problem here.

I like that ...

You probably run that command as root which perfectly returns something. Remember that Cacti normally runs as the cacti user, who does have different rights ( e.g. no ICMP pings ... ).

Try running that script under the cacti user and you will probably get some error message starting with "U" like "Unable to do a ICMP ping" or something like that.

[leoh]

Code: Select all

# su - cactiuser
> perl /opt/cacti-0.8.7e/scripts/ping.pl 10.235.1.1
955

I am not sure that permission is the problem. Eventually, (one in 500 tries or so) the script runs and returns a value which is plotted in cacti. Then, for the next 500 rounds (not really this exact number of tries) it fails.

Also, I don't think that it is timeout issue. I have points plotted showing 3000ms. If the script, once in a while, waits 3s for the return, why would it refuses to plot if it gets less than 1s?
