Cacti shows blank graphs

[ittec]

Hi

I have some troubles with my current Cacti machine. It's based on Centos 5 VPS and is running since 1-2 years. Lately, I have some issues like Cacti doesn't print any info (graph) at some interval. Cacti Poller is set by crontab at 1 minute. I did two things before write this post some days ago:

1. Increase max_memory of php.ini to a high value (I have more than 50 hosts created, all are VPS)
2. Update core cacti files trough yum update cacti to last version in repository: 0.8.7.e

I thought the issue was fixed I was wrong. During some interval of time, Cacti doesn't show any info (blank) in graphs. The rest of time works good.

I have already noticed that there are some Warnings or errors in Cacti Log like:


- 02/27/2010 12:09:04 PM - POLLER: Poller[0] WARNING: Poller[0] Host[66] SNMP Time was not numeric

or

- 02/27/2010 12:09:16 PM - CMDPHP: Poller[0] Host[66] DS[116] WARNING: Result from SNMP not valid. Partial Result: U

Really don't know if there are true issues.

Anybody has some idea to fix this behavior in this CACTI?

Thanks.

Hi after a quick read about your link I tested cmd.php manually and the result is this:

-bash-3.2# php -q cmd.php 66 66
03/01/2010 07:03:59 PM - POLLER: Poller[0] WARNING: Poller[0] Host[66] SNMP Time was not numeric

Can be this a sign of a bad behavior or CACTI?

I found something more wrong, a two crons of poller.php, one in cacti.d and another in crontab. I have removed one of them but blanks graphs are still in cacti.

Thanks
