[XML] successor to apachestats 0.4

[leonardo_gyn]

Hi Guys,

I have installed template on a new Fedora Core 4 machine and got the following errors when running the script:


[root@proxy scripts]# perl ws_apachestats.pl www.mymachine.com
Use of uninitialized value in concatenation (.) or string at ws_apachestats.pl line 63.
Use of uninitialized value in concatenation (.) or string at ws_apachestats.pl line 65.

[root@proxy scripts]#


Error is happening from console with root and with cacti user as well, the user i run cacti processes.

Strange is that I have this script running on some Red Hat 9 machines and got no errors at all.

Is this a new check from newer Perl versions ???

Please tell us what your browser returns when entering www.mymachine.com/server-status?auto as URL. The script awaits some output like

Code: Select all

$output =~ /Total Accesses: (.*)/;
$out .= "apache_total_hits:".$1." ";
$output =~ /Total kBytes: (.*)/;
$out .= "apache_total_kbytes:".$1." ";
$output =~ /Busy.*: (.*)/;
$out .= "apache_busy_workers:".$1." ";
$output =~ /Idle.*: (.*)/;
$out .= "apache_idle_workers:".$1." ";

Please note the apache version

I dont know if this is related, but i upgraded perl and the warnings are gone. Unfortunely i have no fedora core 4 with original perl ... i will have one on the next days and i will redo tests on it.

I will post results until the weekend.

does that pl script work under windows ?

I run it manually at command line and I got

perl G:/root/web/cacti/scripts/ws_apachestats.pl 192.168.1.20
The system cannot find the path specified.

I compare the new script with original one and found new script actually use high speed version which use wget or lynx which I don't have on my windows box, what I can do now?

[dust2k]

Found the problem,

Apache doesn't accept IP as server name to show server-status and I need reconfig the internal DNS name to make it work.

also get wget and modify the script to use right path, everything is alright now.

Your Apache's problem, server-status?auto didn't return proper values.

[leonardo_gyn]

Your Apache's problem, server-status?auto didn't return proper values.

Yeah, i think you are sure ..... i couldnt reproduce the problem and unfortunelly i didnt check server-status?auto URL when I was having the problem. I have tried all combination of things, restarting apache, perl stock and updated versions on FC4 but couldnt, not even one single time, reproduce the error.

I can get server-status page using my IP address (http://192.168.X.X/server-status), dont think that was the problem. In fact i was using www.myserver.com and not IP address ...

Well, i would like to have found a way of reproducing the error so we could handle it, but i couldnt ...

By the time, graphs are working perfectly !!!

[dust2k]

it's bit weired for me to implement it as well, first time it doesn't work, so I changed the httpd.conf and restarted apache, it still not working, even I just brower to test the url, but 5 mins later, everything start working, then I re-test other, everything is working..hehe .

I think we should call that 'Believe it or not' TV show

But are your graphs finally working now, all of them ?

The 5 mins are commonly known as the poller interval. This perfectly normal that it would take at least 5 min (for GAUGE data sources) or up to 10 mins (for COUNTER data sources, difference between two polling cycles will be needed) for data to come up...

Here's a snippet from my /etc/http/conf/httpd.conf

Code: Select all

# ExtendedStatus controls whether Apache will generate "full" status
# information (ExtendedStatus On) or just basic information (ExtendedStatus
# Off) when the "server-status" handler is called. The default is Off.
#
ExtendedStatus On

and later

Code: Select all

# Allow server status reports generated by mod_status,
# with the URL of http://servername/server-status
# Change the ".example.com" to match your domain to enable.
#
<Location /server-status>
    SetHandler server-status
    Order deny,allow
    Deny from all
    Allow from .team-scheck.de
    Allow from 127.0.0.1
</Location>

as well as a module

Code: Select all

LoadModule status_module modules/mod_status.so

After changing the httpd.cond, refresh/restart of apache will be necessary. Of course you'll need tpo customize the Allow directives to your needs.
Verify this by entering sth like

Code: Select all

http://localhost/server-status

as URL to your browser to see sth like the attached picture

yes, all of them, works beautifully, the only issue I have now, the graph doesn't have pure connection chart like the IIS one, but that's ok, not a big problem anyway.

and thanks for lvm's post, it should come bit early then will save me lots of time.

Hello!

Great tool - it is running on another server since several weeks.
With a new installation I have one problem. I read both major threads for "apachestats" now - but can't find a solution.

I installed apachestats yesterday (and the improved version this morning). Installation was without problems, the perl-script can grab the details.

But the graphs are not displayed:

Code: Select all

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="Localhost - Apache Statistics - Hits / s" \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="Hits/sec" \
AREA:#AAABA1:"Hits/sec"  \
GPRINT::LAST:"Current\:%8.2lf %s"  \
GPRINT::AVERAGE:"Average\:%8.2lf %s"  \
GPRINT::MAX:"Maximum\:%8.2lf %s\n"  \
COMMENT:"                            Represents the number of hits per second\n"  \
COMMENT:"                                 ApacheStats v0.4 - Rolf Poser\n" 
RRDTool Says:

ERROR: can't parse '#AAABA1:Hits/sec'

I am using rrdtool-1.0.49.

Any hint to solve this problem would be great - thank you!

Kind regards, Jens

Seems that importing was not ok. The DEF statements are missing for the rrdtool graph. Please re-import the templates and send a screenshot/list of the outcome

Hello!

Thank you for your answer.
I re-imported (without deletion - is this ok?) the xml-template.
