What browser version. Edit setup.php and change status=no to status=yes and look for error messages.

Larry,

Browser is IE7. Despite changing status=no to status=yes in setup.php, there are no error messages displayed. The RRD file is created in the Cache directory, but there is no image displayed. In fact, the only thing it does do is eventually crash Apache on my Cacti server.

Version 0.31 works with no issues whatsoever !!

Any ideas ?

Oh, thanks a lot!
I don't understand, how could I miss it.

I have upgrade to 0.8.7b and new plugin arch and updated all the plugins. All plugins work except realtime. The window displays with the no image icon and no files are created in the realtime folder. I can't find any logs in httpd or cacti.log to give any indication anything is wrong.

I wonder if there is a permissions issue in the way the realtime plugin is being executed. How does realtime query SNMP values? Does it use the lib snmp.php, ping.php, etc, does it use raw sockets to do the test? Is there a way to manual execute some of the realtime scripts to test for permissions? This feels very similar to the advanced ping issues I had with "pinging" as the owner of cacti, but was able to as root.

Thanks

Cacti Version - 0.8.7b
Plugin Architecture - 2.1
Poller Type - Cactid v

It's entirely possible that this could be related to the poller. Of course, Cactid is not supported under 0.8.7b.

I'll PM you the most upto date. Let me know it that works. Does it work in Firefox?

Thanks Larry. I can also confirm that it doesn't work in Firefox either...:(

This is likely caused by you attempting to create a raw socket using cmd.php for an ICMP ping, which of course is not permitted from a non-root account (apache). Can you confirm. I guess I also need to research that in this context. Should we be performing availability checks, or even using cmd.php.

I will consider this as well as a fix/workaround for problems in IE.

I'm getting ready to do another push 0.33 here shortly. It allows the system to use both full Ajax and a forced Ajax for IE (aka Page refresh). It also removes uptime checks from the poller.

TheWitness

Post by **TheWitness** » Wed Apr 30, 2008 8:50 pm

I just pushed v0.33 on page1. It addresses a few issues seen here:

-bug: Some browsers have problem with the Ajax method, make optional
-bug: Remove cacti availability checks as they cause problems with some systems.

Again, only compatible with 0.8.7b.

Regards,

TheWitness

solved my errors and i can see the realtime graphs

Unfortunately, V0.33 is still the same - won't work for me. All it seems to do is crash Apache on my system, despite switching ajax on or off :(

Gone back to V0.31, which works great.
