Sorry for the delay in responding. Your php environment may have run out of memory. The best thing to do there is open a sql window and run the following query:

select count(*) from poller_output;

If it comes back large, you should first increase your php maximum memory, and then run the following command from the mysql console:

truncate table poller_output;

The poller_ouput=0 when i run the command which you have given.

Any idea how to solve the graphing issue.

Thanks

Have you run the poller by hand? You should do that. From the command line "php poller.php", "php <path_cacti>/cmd.php".

Setting Log Level:
1) Login to the Cacti web site
2) Goto Settings
3) From the General tab, select Medium as you logging level.
4) Select "Save"

Running Poller:
1) Open a shell
2) cd to the cacti directory
3) run "php <path_cacti>/cmd.php" to see the poller output
4) run "php poller.php" to see rrd messages and results

Hi,

I get the following results when I run the command:

root@cacti# php poller.php
......
waiting on 1/1 pollers.
waiting on 1/1 pollers.
waiting on 1/1 pollers.
waiting on 1/1 pollers.

I have increase the memory_limit of php.ini to 128MB. Correct me if I had edited the wrong path.

As for the command of php <path_cacti>/cmd.php the following are the results:

root@cacti# No input file specified.

Hi,

I have recreated some network switches for the graph plotting. However, it seems that cacti cannot recognise the new machine. I have enable the debug program it prompt me that:

RRDTool Says:

Error: opening '...................rrd'" No such file or directory

Please help

That "no such file or directory" when referring to an RRD file means that you aren't polling. As soon as you successfully poll, it will create the RRD file. I can't help you with the waiting on 1/1 pollers error though...
