Graphs not showing in Red Hat 9 installation

tovythomas · Post by **tovythomas** » Fri Feb 11, 2005 3:47 pm

Hello,

I am newer to the use of cacti and am working on an installation. I have installed all the components. I am using Cacti 0.8.6c with RRD Tool 1.0.49 and PHP 4.2.2.

When I create a graph, I get the broken link. When I check the data source debug, I get the following.

/usr/local/rrdtool-1.0.49/bin/rrdtool create \
/var/www/html/cacti/rra/salem_twc_router_traffic_in_28.rrd \
--step 300 \
DS:traffic_in:COUNTER:600:0:100000000 \
DS:traffic_out:COUNTER:600:0:100000000 \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \

However, when I do the graph debug, I get the following,

ERROR: opening '/var/www/html/cacti/rra/salem_twc_router_traffic_in_28.rrd': No such file or directory

The file does not exist in the directory. Any ideas?

Has the poller run for at least one pass?

If so, can you set the logging, located in Settings -> General -> Poller Logging Level, to Debug and post on pass of the poller from the logs/cacti.log file.

This way we can help you debug the problem.

I have recently reinstalled the cacti and somehow the graphs will now generate. However, the graphs are not showing any data in them after several polling periods. I ran the php poller.php for debug results and received the following:

Any Ideas on why there is no data. I have tried a netware server-volume information and the interface statistics on a Cisco router with the same results.

Check the permissions on the on the rra directory and files located in it. They are probably incorrect.

tovythomas · Post by **tovythomas** » Tue Feb 15, 2005 5:22 pm

I have checked the permissions and they are set to root which is the same user that the poller is using to collect the data in the crontab file.

Still no data though.

You should run poller.php manually from the command line and look for errors.

I have run the poller manually and it is not showing any errors. My graphs however arent picking up the data. Here is the screenshot of my graphs as of this morning. They have been polling all night.

Can you snmpwalk these devices from the cacti server?

Are you using SNMPv2? If so, make sure you are either using Cactid or have NET-SNMP utils installed.

tovythomas · Post by **tovythomas** » Wed Feb 16, 2005 8:50 am

I am using the cmd.php as opposed to the cactid poller. I know you can snmp walk these devices b/c I am using the cacti server on the same machine as MRTG which is using snmp to pull this same data I am trying with cacti.

I am using snmp v1.

Post by **rony** » Wed Feb 16, 2005 9:12 am

Ok, run the poller manually, in debug mode, and attempt to run the rrd update from the command line.

Code: Select all

usr/local/rrdtool-1.0.49/bin/rrdtool create /var/www/html/cacti/rra/localhost_mem_buffers_3.rrd --step 300 DS:mem_buffers:GAUGE:600:0:U RRA:AVERAGE:0.5:1:600 RRA:AVERAGE:0.5:6:700 RRA:AVERAGE:0.5:24:775 RRA:AVERAGE:0.5:288:797 RRA:MAX:0.5:1:600 RRA:MAX:0.5:6:700 RRA:MAX:0.5:24:775 RRA:MAX:0.5:288:797

Let me know what you find.

Also, I ran that code previously mentioned for the rrd update and it brings me back command line prompt.

Why didn't I think of this before....

I am not sure how the previous article applies, so I may need further clarification.

I have created my devices per the instructions listed in that article. Also when I look at the data source debug, I dont see any duplicate lines but maybe I am missing something. I have added a screenshot of one of my data sources.

tovythomas · Post by **tovythomas** » Thu Feb 17, 2005 8:48 am

Here are 2 screenshots, 1 of the directory permissions as well as the files with in the rra directory. The other 1 is of the crontab entry I had made.

The only other thing I can think of which I think is right is for my database username I have used root with no password. I did not create the optional user in my installation, but I couldn't get it to come up at first without changing the defaults away from cactiuser with a password of cacti.

I have in my include/config.php file the following.

database type = "mysql";
database default = "cacti"
database hostname = "localhost"
database username = "root"
database password = ""

I am not sure if I messed anything up there that would be causing me a problem or not. I imported the default database and then used the root user for everything in the setup.
