There are lost of possible errors that may result in this message. First, be sure to follow the instructions of the installation manual to the letter (e.g. permissions, crontab, ...). You may have a look at my signatures link on "NaN Debugging", but this does not match exactly

[root@xpb-monitoring ~]# /usr/local/apache/htdocs/cacti/poller.php
-bash: /usr/local/apache/htdocs/cacti/poller.php: Permission denied

[cactiuser@xpb-monitoring ~]$ /usr/local/apache/htdocs/cacti/poller.php
-bash: /usr/local/apache/htdocs/cacti/poller.php: Permission denied

but i did notice when running this command like the directions say it doesnt update any rows...

mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cacti';
Query OK, 0 rows affected (0.03 sec)

This seems to be an issue with cactiuser and access to php binary. Please login as cactiuser and try

Code: Select all

which php
, to see, if this binary is in the search path.
Unfortunately, I currently don't have access to my testing system, so all this is out of my memory and may lead into a false direction

i have graphs! thanks! well the picture of the graph is there but no lines/data or anything...

does that poller command need to be in the crontab of root or cactiuser?

any ideas why i have no data on the graphs? SNMP appears to be working. I am getting no errors and can snmpwalk fine

Please see my signature's link on NaN debugging. Take time for each step. If you're stuck at any point, please report so I can improve that HowTo
