[XML] successor to apachestats 0.4

gandalf · Posted: Sun Mar 09, 2008 6:02 am Post subject:

With Cacti 087b (at least), handling of ALL|SIMILAR_DATA_SOURCES_(NO)?DUPS has been corrected.
Unfortunately, this unveils an error with the old "Thread" Graph Template. This is due to the fact, that the AREA/STACK was using the MAXIMUM consolidation function whereas the TOTAL uses AVERAGE. As AVERAGE was never used, the Total of ALL never used datasources is "nothing"; ugly.
So I changed AREA/STACK to AVERAGE and now the Total shows up as requested.

Please be aware of the fact, that even the LEGENDs (Current, Average, Max) are referring to the CDEF=ALL_DATA_SOURCES_NODUPS which is now calculated for the AVERAGE consolidation function.
So, I you were assuming, e.g. the Legend for totalling "MAX" would refer to the Sum of all data sources Maximum of all Maxima (as it should), please note that is only sums the Maximum of all AVERAGEs.

Hye,

I'm a new user of this forum.

Thanks a lot for your scripts and templates.

I've a little problem with it. I think that this is the apache configuration who isn't good.

I have any graphs for "Apache statistics kbits/s", hits, etc ...

But I have no problem "Apache statistics with thread details"

I have this in run the perl script manually :

perl ws_apachestats.pl localhost
apache_busy_workers:1 apache_idle_workers:9 thread_O:246 threadC:0 threadD:0 threadG:0 threadI:0 threadK:0 threadL:0 threadR:0 threadS:0 threadW:1 thread_W:9 apache_cpuload:W__..___.____...................................................................................................................................................................................................................................................

Please, can you help me ...

The data is retrieved from "server-status" URL. IMHO, server-status does not print information on memory consumption, does it?

Is there a way to display grand total hits, not as a graph but as a total number on the output of the legend below the graph?

**Well, I hate to come back here and just say "I figured it out" because its hard! And most forum threads and google searches end in a post that says "nevermind I figured it out" without telling how to do it

But, nevermind, I figured it out.

I even managed to compound my graphs in to one super graph of apache hits/s,hits/min,hits/hr,hits/day once I mastered cdef, which really only took a few minutes once I finally found the post that referred me to the rrdtools cdef tut. which is here by the way: http://oss.oetiker.ch/rrdtool/tut/cdeftutorial.en.html

Got some prob.

Thanks to Gandalf, the owningmaster of Cacti

, i've seen that there are some new stuffs for Apache Statistics with new versions of Cacti :

- a new ws_apachestats.pl file, i've updated it on my Server2
- a xml file of the host_template, but i don't know where to update it, and what for ?

At this stage, my graphs of Apache stats still don't work, and the command perl ws_apachestats.pl localhost or perl ws_apachestats.pl myremothost.domain.com return nothing.
For information, my previous version of ws_apachestats.pl returned

I've discovered that my server2 had to be able to contact the server-status page, and it can't.
It must be an allowing rule for server2 to contact the status page in the Apache configuration file on target server , or somethg...

by default, server-status is commented out,

yep !! I've finally found what was wrong, i just had to add "Allow from IP_of_my_server2" in the apache2.conf target host
