Disk full because of log file

[Claude Girard]

Hi,

Rev 8231

ping.class.php writes Warning messages in log file all the time.
So file size is growing a lot.
Here are messages:

Jun 23 13:36:20 crim-fog FOGPingHosts[1064]: PHP Warning: fsockopen(): unable to connect to 172.20.41.231:445 (Connection timed out) in /var/www/html/fog/lib/fog/ping.class.php on line 38
Jun 23 13:36:20 crim-fog FOGPingHosts[1064]: PHP Warning: fclose() expects parameter 1 to be resource, boolean given in /var/www/html/fog/lib/fog/ping.class.php on line 39

I could stop this by modifiyng lines 38 and 39 in ping.class.php like that:

38 $fsocket = fsockopen($host,$port,$errno,$errstr,$timeout);
39 fclose($fsocket);

replaced by:

38 $fsocket = @fsockopen($host,$port,$errno,$errstr,$timeout);
39 if ($fsocket) fclose($fsocket);

But I don’t know if this is correct, since Tom removed at symbols in this commit:

you can also turn off the ping hosts feature altogether.

[Claude Girard]

Thank you for this information.
But how can I do that ? I don’t find.

And isn’t this ping host feature used to see green light in front of the host ?

[Wayne Workman]

But how can I do that ? I don’t find.

Web Interface -> FOG Configuration -> FOG Settings -> General Settings -> FOG_HOST_LOOKUP

And isn’t this ping host feature used to see green light in front of the host ?

Yes.

[Claude Girard]

ok thank you

I should open my eyes

[Quazz]

The @ in front of a function simply surpresses the warning. Tom disabled that to have more verbose output to work it to make it easier to resolve problems.

[Tom Elliott]

@Quazz I also did it because there were a lot of calls using the @ symbol. Using @ in front of functions is actually very taxing on the server too.

Yes I first want to preserve my disk space
But pinging host is very usefull.

So I don’t know how to solve these warnings, I’m not a php programmer.
It seems that timeout in fsockopen function doesn’t work for offline hosts

[Tom Elliott]

I’ve added some minor code in hope to help thwart the spamming of the log with these fclose warnings. Typically, there should be plenty of space for the root partition (/) to write its log files. What is your FOG OS’s partition layout? df -h

[Claude Girard]

@Tom-Elliott
Images are on a separate partition.
/ partition is 12 Go, today I can see 5 Go free.
This is enough, but not when dozens of lines per second are written in log file.
And whit this one (ping), 2 warning messages are written for each host not on line.
It can grow rapidly.

[Tom Elliott]

You could disable logging, though I’d highly recommend against it.

[Claude Girard]

@Tom-Elliott
Maybe disable only warnings messages ?
So I mark this resolved
Thanks
