Does cacti has device number limit ?

[izhou]

Hi
Does cacti has max device limit?
I have add 30 devices, the cacti is ok,
when I add a new port in cacti, then the cacti not work any more,and rra file don't update. what's wrong ?

My log:
03/26/2006 11:00:10 AM - CACTID: Poller[0] Host[27] DS[1177] WARNING: Result from SNMP not valid. Partial Result: ...

Those two data sources are trying to poll an invalid OID. Enable debugging logging in cacti to find out exactly what OID it is. Alternatively, you can click on the DS[1177] link, when viewing the log file from within Cacti.

But my question is why the rra don't update when I add or remove a device to cacti?

The rrd files are not being updated for those data sources because cacti is not collecting data. You did not enable debugging logging.

Turn the polling level in cacti to debug (Settings | Polling level) for one cycle, wait for Cacti to run, and paste the output of the actual log file (<webroot>/cacti/log/cacti.log). If it contains WEBLOG entries, then don't bother posting since they just clutter up the log. Turn off WEBEVENTS logging and try again.

The cacti is work good and rra file is update .
but if I add a new device , the rra file will not update any more.

I enable debugging logging.

I have solve the problem。I open the file /etc/php.ini，edit the line memory_limit = 8M to 256M. So the cacti work again, and graph update ok.
