Advanced Ping Template for Cacti 0.8.6f

[gandalf]

What version of Cactid?

TheWitness,
my problem is gone using cmd.php. So it seems to be an issue between cactid and php script server. Here's the log snipped running cmd.php

09/14/2005 09:05:02 PM - PHPSVR: Poller[0] DEBUG: INCLUDE: '/var/www/html/cacti-0.8.6f/scripts/ss_fping.php' SCRIPT: 'ss_fping' CMD: 'gandalf 20 TCP 80'

But this is not really an option. cactid is way faster.

Any devices/graphs I create using Advanced Ping will create RRDs and appear to be working great but the graphs will not show up properly in Cacti (just a red X).

When I run http://host/graph_image.php?local_graph_id=368 instead of a graph I get a single 0 on the screen. I can run that same command with any other graph id and it shows the graph properly.

Will you make this available for those of us running 0.86g? Or are there changes we could make to get it to run without having a machine already with 086f?

run on win2k
cacti0.8.6f with pre-patch applied.

I can see the Adping graph in the graph management,
but I can see it on the "graph tab"

any suggestion?

[vector]

Can I use this to check for an HTTPS or HTTP site using hping? How can I set parameters?

[TheWitness]

Yes, but I need to alter the template a bit.

Cool script!

So far I have progressed quite far, but I seem to have run into the permissions fault a few other people are reporting.

OS: Gentoo 2.6.12-r10
Cacti: 0.8.6f-r1
0.8.6f-pre-patch: Applied

If the script is tried in the CLI as root

I don't really want to run the poller as root if at all possible, Is there a way to use UDP instead? I think UDP pings don't require root permissions.

[TheWitness]

ss_fping.php hostname ping_count [ICMP] || [[TCP] || [UDP] && PORT_NUM]. The additional features were placed in 0.8.6g

TheWitness

[glowworm]

The additional features were placed in 0.8.6g

I have now upgraded to version 0.8.6g and applied all the patches in the downloads area. I can see a change in the ss_fping command.
0.8.6f-r1

Code: Select all

function ss_fping($hostname, $ping_sweeps=6)

0.8.6g

Code: Select all

function ss_fping($hostname, $ping_sweeps=6, $ping_type="UDP", $port=80)

But the data template still only shows two fields. (see attachment).

[gandalf]

Instead of entering "20" for the Number of Times ... you may enter "20 TCP 80" if you want to ping 20 times using TCP on port 80. Or "20 UDP 80" for UDP. Of course you may enter another port. This even works for me (using cacti 0.8.6g). Cacti will simply pass all 3 parms to the script...
Reinhard

[glowworm]

you may enter "20 TCP 80"

I should have thought of that! Anyway I tried "20 UDP 80" and it timed out, so I thought I would try it on the CLI as root.

Code: Select all

# php ss_fping.php  www.google.com 6 UDP 80

hung while

Code: Select all

php ss_fping.php 192.168.1.1 6 UDP 80"

worked. In other words I can UDP ping all the machines on my network, but nothing on the internet.

I 'spose it could be a router/firewall issue with my WRT54G, so I put my cacti server in a DMZ but unfortunately no go. TCP and ICMP both work as root but UDP always times out.

Does anyone have an idea where I could start looking? Thanks.

[gandalf]

I 'spose it could be a router/firewall issue with my WRT54G, ...

No, not necessarily on your side. Can you imagine what the google admins may have done to prevent their servers from such "distributed denial of service" attacks? Well, I don't know exactly...
I'd prefer to use such ports that are open to public. In this case I'd have taken "20 TCP 80" or so. Why do you want to use UDP?

Hello,

I run cacti 0.8.6g under Freebsd 5.4/Apache 2/ MySQL 4.1/ PHP 5.0.5.
I have a problem with ss_fping I think : When there is a packet loss, the script does not end and I have the following error in cacti logs :
10/06/2005 11:31:07 AM - CACTID: Poller[0] Host[4] DS[26] WARNING: Result from SERVER not valid. Partial Result: ...
10/06/2005 11:31:06 AM - CACTID: Poller[0] WARNING: The PHP Script Server did not respond in time and will therefore be restarted

When there is no packet loss, there is not problem and the advanced ping graph is correct.

Thanks for your help.

Fanu.

[TheWitness]

fanu,

I have noted this and did correct the issue in my production environment. I will post a new ss_fping today, if I get a chance.

[fanu]

Thanks a lot!
I will wait for the new ss_fping.
Thanks for your help and your disponibility. Your work is great.

Fanu.
