Gentoo - no graphs [Solved]

[cpaasche]

Hi,

I have Cacti installed on my Gentoo box. I am getting snmpwalk output from it. Also, a Windows XP box & Windows 2000.

Code: Select all

Cisco_7200 cacti # snmpwalk -v 1 -c community 192.168.100.182 .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux Cisco_7200 2.6.19-gentoo-r5 #3 SMP Sun Feb 11 23:33:09 PST 2007 i686

Cisco_7200 cacti # snmpwalk -v 1 -c community 127.0.0.1 .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux Cisco_7200 2.6.19-gentoo-r5 #3 SMP Sun Feb 11 23:33:09 PST 2007 i686

Cisco_7200 cacti # snmpwalk -v 1 -c community localhost .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux Cisco_7200 2.6.19-gentoo-r5 #3 SMP Sun Feb 11 23:33:09 PST 2007 i686

I'm using Vixie-cron

Code: Select all

Cisco_7200 cacti # crontab -u cactiuser -e

#*/5 * * * * php /var/www/localhost/htdocs/cacti/poller.php > /var/www/localhost/htdocs/cacti/poller.php 2>&1
*/5 * * * * php /var/www/localhost/htdocs/cacti/poller.php > /dev/null 2>&1

First line when uncommented just gives me email error messages in /var/log/messages so I figure it's not related.

Second line gives me this.

Code: Select all

Gentoo howto says....

Code: Select all

chown -R apache:apache rra/ log/

Tried that, didn't work so I did as in the Cacti User Manual.

Code: Select all

Cisco_7200 cacti # chown -R cactiuser:cactiuser rra/ log/

Everything else is root...is that correct? Or should it be cactiuser as owner?

After looking at the Gentoo forum, this forum & the howtos, I get as far as this when looking at the Data Query Debug Information. Associated Data Queries shows success as status with 27 items in 3 rows.

All the output is not from the same snmp host but I get the same one all of them. snmpwalk works. Data Debug Query is populated. No charts & "'/var/www/localhost/htdocs/cacti/rra/localhost_load_1min_5.rrd': No such file or directory"

Hosts say either down or unknown in Console -> Devices

Thanks in advance.

I've got this solved.

First off, I had to add bundled-adodb to my /etc/make.conf file & recompile cacti. That brought up the systems & updated the stats in Console -> Devices.

Next, I had to run "php poller.php" from the cacti directory as root....as the apache user it did not work. That populated the rra/ directory. Then I changed permissions of rra/ & log/ back to apache.

Next, I made sure the OIDs on the graphs I was trying to use were defined & made sure I could snmpwalk them. Some were not.

I was getting mysql insert errors in my log files but at least I had output as was not the case previously.

I added a cronjob for the Apache & killed the job for cactiuser. I wasn't clear on that point.

Lastly, I experimented with permissions. mysql, apache & cactiuser (& groups). I'll start pulling users out of groups & see when it breaks.

Basically A LOT of howto & forum reading did the trick along with the troubleshooting walkthrus here.

Dear cpaasche,

I'm having the same problem as you have...

I can snmpwalk my win2003 server, and cacti is saying that it recieves data, but there are no graps, just like in your screenshot.

In the attachment you can see my php poller.php .
It want's to create the graphs in /var/www/html/cacti/rra/ but it doesn't.

Maybe it's a rights problem? Which owner/group does /rra and /log got to have? The same as the MySQL database username??

I hope you can help me out.

Please read installation hints at http://docs.cacti.net.
And it would be better to open a new thread instead of reusing a thread that reads solved in the title
