According to the PM that I received from the user, he had made his poller_output_boost table "output" field width too small, thus causing these errors. He increased it's width and the problem went away. Always keep this in mind when running boost. TheWitness My graphs stopped updating as ...

Please help me how can i know if the poller.php is working ?, I ran from cli: [root@localhost cacti]# php poller.php Content-type: text/html X-Powered-By: PHP/4.3.9 but i didn't have another line that told if all is ok. I don''t known if it's de reason why I can't do any graph with cacti , allways ...

The file owner depends on the user that runs the poller. Assuming you've followed the standrad requirements, here's the setup: - you've created a "cactiuser" - cron has been setup for "cactiuser", e.g. "crontab -e -u cactiuser" - so the poller.php is run by "cacti...

Sorry, my question may have not been precise enough. Are you using SNMP for downed host detection? Are you using spine or cmd.php? Did you already see 2nd link of my sig? Reinhard We are using SNMP, and cmd.php should we be using spine? *UPDATE* I got it to work and it graphed for 15 minutes and st...

Your problem is related to downed host detection in most cases. What do you use for that host? ICMP or SNMP?
Reinhard

We are using snmp on the Cisco Routers model 7200's do you have any tips?

I have searched on the web, and found various different howtos on Cacti, however I am still hung up on the graphing. In debug mode I get this error message: RRDTool Command: /usr/bin/rrdtool graph - \ --imgformat=PNG \ --start=-86400 \ --end=-300 \ --title="ir1.pgtc.net - CPU Usage" \ --ri...

THANKS a million I am checking out the docs right now.

I downloaded the .tar.gz file and untar'd

Now I have new problems to work through....

It depends on what/how you are going to monitor. The basic monitoring framework is SNMP. That implies port 161. But also, you will need to have your agent setup on the remote device to respond to inquiries, normally Net-SNMP. There are other ways to monitor, such as diskspace, running processes, bu...

If you add a new device such as a Linux server, do you have to open
a port on the firewall?


Also, does the server you are trying to monitor have to be running
snmp?

How do you know what snmp version to use it has 1/2 or 3?

If I downloaded the tar ball would that work?

I am a bit confused.

I am at a loss, I have enabled the EPEL repo for RHEL5.3 to do a yum install cacti, however I have no data in the /var/www/cacti directory? I have a Cenos5 box 32bit and I have installed cacti on it and when I do a rpm -qa against cacti I get the same package data. I am very confused on why it insta...
