Serverstats FAQ (Frequently Asked Questions)
Version: $Id$
===============================================================================
===============================================================================
1. I have installed serverstats, but my browser does not display one or more
graphs / images are broken.
==============================================================================
* Have you installed a PHP version >= 5.0?
-> install PHP 5.x because serverstats is not compatible to PHP <5.0
* Have you installed a rrdtool version >= 1.2?
-> install rrdtool >= 1.2, because old versions are not 100% compatibe
and sometimes don't output errors
* Have you a complete config in config/ directory?
-> copy config.sample/ to config/ will install a simple, but
usually working config
-> or set up your own config in config/ directory, see doc/ for
assistance
* Have you set up the cronjob to update the stats?
-> set up a cronjob like:
* * * * * php /path/to/serverstats/update.php
* Is rrd/ and cache/ writable for the user running the update.php cronjob?
-> use 'chown' to set the appropriate permissions
* Is graph/ writable for the webserver user, which should create the graphs
here?
-> use 'chown' to set the appropriate permissions
* Have a look at rrd/ directory - is there a .rrd file for every used data
source (cpu.rrd, load.rrd, users.rrd...)?
-> run 'php update.php' from commandline to see any errors when trying to
create .rrd files
* rrd files are created and graph/ has appropriate premissions and still
no graph is created?
-> right-click the broken graph image in your browser, and
select "view image". This should display a serverstats/rrdtool error
message, to help you where to look at
===============================================================================
1. PHP exits with an error telling that ArrayIterator is missing, have you
forget to include that?
==============================================================================
* ArrayIterator is part of the SPL, you have to compile PHP with SPL-support or
enable it if its compiled but disabled.
-> Gentoo: USE="spl" emerge php
