Problem loading Graph

[mhasan]

I'm a first time cacti user. It takes too much time to load the graph. Sometimes graph image disappeared, it appeared after reloading the pages. I've attached screenshot.

Cacti Version: 0.8.7g
PHP Version 5.3.3-7+squeeze14
Apache/2.2.16 (Debian)

Please help me out. My boss killing me.

I'm not sure what you are trying to show your problem is.
What do you mean by it takes too long to load?
What does the picture mean after reload? After reload page, or reinstall cacti?
Please explain your problem in more detail.

After auto refresh my page appear like this image cacti_graph_before_reload.jpg. When I reload the page from browser it appear like cacti_graph_after_reload.jpg but It take too long.

I made cisco catalyst 2950 graph. When I click on tree to see the graph 1st 3-5 (port's) graph image appear and rest of them doesn't.

I'm using Google Chrome as my browser. But didn't find any problem with Firefox.

Sounds like maybe you don't have enough time in allotted for your php script runtime in php.ini, or your system is under a lot of load.

Many many thanks for your reply. Can you give me a guideline to fine tune my web server, php & mysql for run cacti smoothly. My network getting bigger so I have to add many devices to monitor.

Thanks again.

Most situations are different, and I know nothing of your equipment(speed, ram, disk speed, etc), network, etc.
Google mysql optimization and php optimization. That should help you.
Also, check your log files(apache logs) to see why things are failing.

Are you running 1 or 5 min polling?
Are you running spine?
How many data sources etc. (grep for "SYSTEM STATS" in cacti.log)
Considered using BOOST?
