EDIT: Advanced Ping Template Version 1.3 for Cacti 0.8.6g

[ixtab]

i got the same problem when i install advenced ping, i'm working on CentOS and Cacti 0.86h, so if you cant tell what did you do to resolve your problem i will thanks i lot of...

Hi Lvm,

I am using cacti0.8.6h, I only imported the advanced ping template since the ss_fping.php and ping.php already exists in the cacti directory. Im wondering why I am getting nan values or my graph is only red. I tried manually the ss_fping.php script using script server and the result is good. However when I used rrdtool fetch on the database all I can see is nan. Anybody has any idea here? or Do I have to overwrite the existing ss_fping.php or ping.php with the ones you posted.

Thanks and Good Day

Everything appears to be in order, but getting the following error on this script:

[root@linux cacti]# php /var/lib/cacti/scripts/ss_fping.php www.google.com 20
PHP Fatal error: Class 'Net_Ping' not found in /var/lib/cacti/scripts/ss_fping.php on line 25

Net_Ping is installed:

Any idea what the problem is?

Witness thanks for a new and improved ping tool I have one question / request. Would it be possible to specify the length of the ping packet. Something like microsoft allows with the -l variable, like this :

ping 1.1.1.1 -length 1500

so that a user could "emulate" a standard ethernet packet.

[TheWitness]

Well, it's entirely possible, but it's not high on my list of priorities and currently the php based ping library is not written for it. So, since that is a "base"/"core" module, it may not happen for a while.

Kindly advice:

does the ping utility give me the option to ping several IPs at one go.

For example i have Router A, and i want it to ping the Router B C and D

And lets say from Router G, i only want it to ping a particular server

Can this be setup using the advanced ping utility?

does anyone know if this is fixed in 0.8.6i?

you must include the script path first:

/www/html/cacti/scripts/ss_fping.php ss_fping 10.1.1.2 20 ICMP

So, the syntax is:

script_path function_name_to_call function_parameters

That works and responds with correct ping values, now when I use the graph on one of my hosts it comes up with 100% no replies. I set it up for 20 tries and ICMP and no response, when I do it from SSH though I get perfect replies.

[TheWitness]

Run the poller as root and all will work, otherwise, I believe if you run cactid as setuid, then it should work. ICMP packet's can only be generated as a root ID. You also have the option to use TCP pings to some known "open" port.

I have changed the file and group ownership on <cacti path>/poller.php, <cacti path>/lib/poller.php, <cacti path>/lib/ping.php, and <cacti path>/scripts/ss_fping.php from apache to root. Am I missing something because this still doesn't work for me.

Is there something in Cacti where I tell the Graph to run as root? Sorry for being such a n00b and thanks for your help so far!

[wwolkers]

kevandju,

what you changed are the permissions... the poller is run by cron, and to be able to do ICMP it needs to run as root, check your cron setup.

mine is in /etc/cron.d/cacti

*/5 * * * * www-data /usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log

currently running as the www-data user, if I want to do ICMP pings, I need to change that to root

[kevandju]

That did it, thanks a bunch!!
