cacti Apache Web Hits the graph is empty

[cc]

Hi

I've installed the cacti Version 0.6.8a on linux SuSE8.1
By default I get all system graphs like Load Average, Memory Usage,
Logged In Users etc.
Only the Apache web Hits graph is empty and I don't know why:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start="-86400" \
--title="Apache Web Hits" \
--rigid \
--base=1000 \
--height=150 \
--width=500 \
--alt-autoscale \
--vertical-label="Hits" \
DEF:a="/srv/www/htdocs/cacti/rra/system_webhits.rrd":system_webhits:AVERAGE \
CDEF:cdefa=a,300,* \
AREA:cdefa#7EE600:"Web Hits" \
GPRINT:cdefa:LAST:"Current\:%8.0lf" \
GPRINT:cdefa:AVERAGE:"Average\:%8.0lf" \
GPRINT:cdefa:MAX:"Maximum\:%8.0lf\n"

Should I change someting at my apache configuration ?
I tried to atack my apache with the web stress tool ,
but still no entries !

Did you check the datasource to make sure it is pointing to the location of your access_log?

[cc]

Hi

You mean, the path at rrdtool Data Source Configuration:
/var/log/httpd/access_log
it is OK.

chmod +r /var/log/apache/access.log
solved it

Hi

I did chmod +r /var/log/apache/access.log, but still no graph.

Some posts earlier you wrote that your log file is /var/log/httpd/access_log. Why do you make chmod on /var/log/apache/access.log?

Hi

Sorry, I did chmod +r /var/log/httpd/access.log,
but I wrote wrong.
It doesn't help and still NO GRAPH.

Still the names are different: access_log and access.log - maybe this is the reason of your ptroblems?

Sorry, what I did exact:

linux:~ # cd /var/log/httpd
linux:/var/log/httpd # chmod +r access_log

I did correct, otherwise I get error.
Still doesn't work !
At other linux server is working and I cheked all configurations
many times. They are the same.
I thing is NOT the chmod problem, because at other linux I didn't chmod
anything and is working.

Hi, on all my debian systems the webhit did not work... the problem turned to be the read access to the access.log
So... make it readable for cacti

[cc]

I did, but it doesn't help.
I have 3 linux server: all with the same cacti Configuration.
At two of them ( SuSE 8.0 & SuSE 8.1 ) webhits are working
and only one is NOT working ( SuSE 8.1 ).
At those 2 computers, where webhits are working,
I didn't chomd anything, I mean the access_log.
I don't understand that !

Hi

My access_log is now:

linux: /var/log/httpd # ls -l
-rw-r--r-- 1 cactiuser root 355207 Mar 7 20:55 access_log

Still doesn't work.

How does look like your rrdtool update command line (you can find it when you click "Edit Data" link near your data source name).
