no graphs in cacti, CentOS

[mnilsson@udcom.net]

Hi

i have installed cacti and added the crontab line for poller.php but still the cacti does not show any diagrams and i guess i have beeing messing around do much in the Mysql and added users according to the manual in CentOS and added more users and grant access as well.

on the cacti page when i turn on debug of graph i get the following:

********************************************

RRDTool Command:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="mc3810 - CPU Usage" \

AREA:a#FF0000:"CPU Usage" \
GPRINTLAST:"Current\:%8.0lf" \
GPRINTAVERAGE:"Average\:%8.0lf" \
GPRINTMAX:"Maximum\:%8.0lf"

RRDTool Says:

ERROR: opening '/var/www/cacti/rra/mc3810_5min_cpu_24.rrd': No such file or directory

*****************************************************************

i checked the directory and that is true i have no rrd file in that directory ...

I guess i need to configure the snmpd or what ???, i will look for error log in snmpd, apache, cacti all is possible ...

Please try some tips of my Nan Debugging HowTo. They do not exactly match your request. But they show a lot of tips how to find log infos and more

Also try manually doing an snmpwalk from the server to see if it actually pulls back info

Hi

Now i get no data to cacti

I run the line from cacti directory php -q poller.sh and it does not complains but on the other hand the rrd directory with all my rrd files is not updated ...

did an snmpget from that node and i get an answer looks in poller.log and it does not tell me anything except for version number ...

cacti log is not updated at all ....

uninstall mysqld or how do i do it ...

[gandalf]

Please be careful when running the poller.php manually. You should do so only when being logged in as cactiuser (the user running the poller from crontab). Else, permissions/ownership of new rrd files will correspond to your user settings.
So, please set "Settings->Poller Logging Level" to DEBUG for one single run. Login as cactiuser, empty log/cacti.log and run

Code: Select all

php -q poller.php > log/poller.log

from your cacti main directory. Post both cacti.log and poller.log after sanitizing private strings

I have been experiencing the same problem. I still have not gotten it resolved.

I have installed cacti about 10-20 times on fedora. This is my first time on centos.

That is all I get. I am experiencing the same problems as mnilsson@udcom.net.

I should also mention that the SNMP cache and poller cache appears to be populated.

App versions:
cacti-0.8.6j-1.el4.rf
php-mysql-4.3.9-3.22
php-4.3.9-3.22
php-snmp-4.3.9-3.22
rrdtool-1.2.18-1.el4.rf
perl-rrdtool-1.2.18-1.el4.rf
php-snmp-4.3.9-3.22
net-snmp-5.1.2-11.EL4.7

The only big difference I see from Fedora to CentOS is the version of php.

My default localhost graphs are working fine.

I should also probably mention that I ahve tried the RPM version found from RPMForge/Dag and the tgz found on the download page of this site. Both have given the same problem.

SELinux is disabled.

I have also tried cactid. Although I am not really sure how to setup cactid. Whether I should place that in the cron job instead of poller.php?

After several attempts running cactid and then poller and so on I was eventually able to get a rrd/graph generated but it did not work continuously as it should. There would be large gaps of no data and in some cases certain hosts would not graph at all.

Did you try the hints given in my HowTo linked in the second post? Please report your findings, step by step

I eventually reinstalled cactid and found how to use it.

I still cannot get cmd.php to work correctly but cactid works like a charm.
