Re-Hello,

I put the new ss_fping. It seems to be better, but there is still a problem :
when the first packet is lost, the script does not stop (same problem).

What can I do to help you to resolve this ?

Thanks for your help.

Fanu.

Hello,

In addition to my last message, I have done some tests. I set in hard in the script the timeout value to 10 ms. I try to ping www.google.com (about 20ms) and it works : I think my problem is that the ss_fping script (maybe the call to Net_Ping();) never time out. So if there is a lost packet, the script never ends.

Thanks for your help.

fanu,

This may be the issue within the ping.php program caused by the set_scoket_option command. Look for it and then review the timeout issues. In some versions of PHP, it acutally works properly. But in windows (where I code) it does not work as expected.

Read the comments on seconds and microseconds. I think you just have to reverse the order and it will work properly. Try that and let me know.

I could write some detection logic to compare unix vs. windows and modify the commands, but I am not sure what platforms PHP is broken on.

Here is the code:

Code: Select all

/* set the socket timeout */
socket_set_option($this->socket,
  SOL_SOCKET,  // socket level
  SO_RCVTIMEO, // timeout option
  array(
  "sec"=>$this->timeout,  // I assume timeout in microseconds
  "usec"=>0 // Timeout in seconds
));

It would be changed to:

Code: Select all

/* set the socket timeout */
socket_set_option($this->socket,
  SOL_SOCKET,  // socket level
  SO_RCVTIMEO, // timeout option
  array(
  "sec"=>0,  // I assume timeout in microseconds
  "usec"=>$this->timeout // Timeout in seconds
));

It occurs in a few places. Please let me know.

Hello,

Thank you for your response.
I try to do what you wrote but the problem is still here.
I try to force the timeout to 10ms in the ss_fping script but the directive seems to be ignored (I ping some hosts with 300ms of latency, but if there is a packet loss, the script still never end).
I don't know where to search ...

Thank you for your help.

Fanu.

I have a new version of ping.php attached. Please test ss_fping.php especially using UDP pings if you can spare the testing time. Timeouts work like they should now. I abandoned the set option call for the socket select, which appears to be much better developed.

JJX,

What Ping method? Have you loaded the sockets.so PHP extension?

Turns out that after chacking the data template for advanced ping the "per device hostname" field was checked.... ....after unchecking and adding the data template to an existing host it then asked me for the IP to poll..

I'll go and turn it back to snmp-reliable now

Lard

can you explain a bit more?
I'm playing around with this, but didn't find exactly what you are talking about....

When I tried to run this:

PHP Script Server has Started - Parent is cmd
scripts/ss_fping.php ss_fping www.google.com 20 TCP 80

Fatal error: Call to undefined function: socket_create() in /usr/local/cacti-0.8.6g/lib/ping.php on line 298

Im using cacti 0.8.6g and applied the latest ss_fping.zip and ping.zip from this thread but still no luck.

. Im running on SuSE 9.3 OS
