Same Ol' NaN,sorry.

[Miyamoto]

Hello there.
First of all, I'm begging your pardon since I know that NaN is a very common issue and maybe I didn't notice some particulars,but I've spent all day watching graphs and giving CLI commands. I've installed successfully 'Cacti 0.8.8b' on my CentOs 7. I've followed a procedure found here:


http://www.itzgeek.com/how-tos/linux/ce ... z3PvvNMpCI


I tried fixing the permissions,start the poller manually and so on. Initially,I had no graphs on the frontend,but when I started the poller by myself they displayed on the webpage.
Then the NaN appeared. I tried to give permissions on the folders,on the files, 777 and chown,but nothing happened.
Among the Settings on the webpage the timing of the poller and cron should be 5 mins,so it is,on system cron,too. I'm pasting some screen from the logs and the settings,hoping you to help a poor noob (just my second day on Cacti).
PS. The "PATH" tab of the Settings on the frontend is totally correct,I'm quite sure of it,that's why I didn't upload it here.


Hope you won't blame me,thanking you all in advance.

First one is the graph itself,showing the Nan result.

Finally,one of the repeating parts of the logfile. As I said,this part is present multiple times.

Do you have Selinux enabled?

[Miyamoto]

Do you have Selinux enabled?

Don't know,I'ma check tomorrow when I'll be on my VM. Ty in advance!

[Miyamoto]

Hi, I've checked the Selinux config file and disabled it. Still NaN.
I've edited the Snmpd.conf file and still NaN.
When I try to start the poller manually it says that the system time is not synced. In fact,the time displayed in the graphs is one hour before the system time;the system where the Cacti installation is.

What timezone do you have set in php.ini?

[Miyamoto]

I didn't touch php.ini at all...I'm looking at it right now and there's just one place that tells me:



"Defines the default timezone used by the date functions
http://php.net/date.timezone
date.timezone = "



but it's all commented with ";". Almost the whole file is commented. Initially,when I've installed the modules like PHP, Net-Snmp,following that guide I didn't edit many conf files. The only ones are Snmpd.conf and the DB created with Mariadb. My entire installation is full of holes.

[Miyamoto]

PPS. I've found out on the Cacti site some more good hints about the configuration of the many modules like PHP. I'm following it.
We'll update again.

Best Regards

[Miyamoto]

Update: I've read the whole Cacti guide to install and configure the service. I've followed each step I could,but some of the parameters in the .ini/.conf files were different,so I had to go forward.
I still get NaN after all. I don't kow what else it could be.
