Cacti Problem - Poller and Graphs

C

cybercoke

Hi everyone,

i have installed Cacti 0.8.7i on a FreeBSD 8.0-RELEASE, with php5-5.3.8, net-snmp-5.7.1_3, rrdtool-1.4.5 and apache-2.2.20.

Cacti was installed on /usr/local/share/cacti with permissions drwxr-xr-x and owner:group www:www.

The problem is that only when a run the /usr/local/share/cacti/poller.php manually, the hosts start to be in recovering mode and the rrd graphs being to be created, but not populated. If I put on cron to run poller.php as it should be, it gave me the following at cacti.log:

Code:

Here the cacti.log when I run poller.php manually:

The host are configured as Generic SNMP Enabled Host, and the response from snmp when I save it was the following:

Code: 
Web WWW (localhost)
SNMP Information
System:FreeBSD neomail 8.0-RELEASE FreeBSD 8.0-RELEASE #0: Mon Jul 5

Uptime: 542540 (0 days, 1 hours, 30 minutes)

Ping Results
ICMP Ping Success (0.051 ms)

I can do Associate Data Queries with no errors, like SNMP - Interface Statistics and Unix - Get Mounted Partitions.

I can create new graphs with those DataQueries, but they are not populate.

So, my 2 problems are:

1 - Make poller.php run on cron
2 - Make rrd populate the rrd files.

Thanks at all!
 
Hi SirDice, ok, I will update it as soon as possible, but right now, it was working good. It can run cacti ok. Can you help me solve that problem? Thank you.
 
It fails to ping the host, this usually means the SNMP query is skipped too (it's no use trying to scan a device that's offline).

Can you ping the host from the monitoring server? Is cacti perhaps running in a jail?

Yes, I can ping it. It was the same machine (localhost). I can make poller.php runs by hand, but when it was on cron, it dosen't run well.

I understand that not try to scan an offline host.

Thanks.
 
It does take a little while when you create a new graph for the data to appear. It needs a couple of data points before it's able to produce a graph.

Yes, I know it, but I'm two days waiting and running poller by hand and nothing.

The rrd files are created and updated by rrdtool. I know it because date/time and size of files are updated after I run the poller.

Thanks.
 
I suddenly remembered I have a working cacti on one of my servers :D

How did you create the cron entry?

# crontab -u cacti -e
It should look like this:
Code: 
*/5     *       *       *       *       /usr/local/bin/php /usr/local/share/cacti/poller.php > /dev/null 2>&1

My cron is that way:

Code: 
*/5 * * * * /usr/local/bin/php /usr/local/share/cacti/poller.php > /dev/null 2>/usr/local/share/cacti/log/cacti.log

This cron is on root. I try to put in cacti user but it does not start.
I'll try again.

What is the permissions and owners of you cacti directory ?

Thx.

Yes, from a security perspective you don't want this stuff running as root. There's no need for it either.

Note the cacti user on log and rra.
 
Ok SirDice, I just put in the root's crontab for test only. It was now on cacti's cron and running (poller.php).

The permissions are the same, include log/ and rra/.

I was wondering why on the cacti web interface the ICMP ping was "OK" , and the same if I run the poller by hand, but not if they are on the cron.

Thanks.
 
Hi guys, thank you for the help, but yesterday I tried to remove cacti at all and reinstall. I do this by ports installing cacti 0.8.7.h and then upgrade to 0.8.7.i from cacti.net. Installing plugin monitor and everything works fine. Who knows.

Thank you again.
