hi,

I have installed CACTI and other related packages in RHEL 4.4 and everything will installed perfectly. But when i create a graph then the debug returned:

RRDTool Command:

RRDTool Says:

sh: /usr/local/rrdtool-1.0.50/bin/rrdtool: Permission denied

I set the permission of rrdtools as
-rwxrwxrwx 1 root root 824863 May 12 18:44 /usr/local/rrdtool-1.0.50/bin/rrdtool

But the problem is the same.
The tail -f /var/log/httpd/error_log is shown:
sh: /usr/local/rrdtool-1.0.50/bin/rrdtool: Permission denied

I am tried to solved the problem. So Plz help me

Thanks and regards

Do you see In System Utilities> Technical Support :
ERROR: Installed RRDTool version does not match configured version.
Please visit the Configuration Settings and select the correct RRDTool Utility Version.

Thanks for ur suggestion. Here is the general information:

Date Sat, 17 May 2008 18:35:45 +0600
Cacti Version 0.8.7b
Cacti OS unix
SNMP Version net-snmp
RRDTool Version RRDTool 1.0.x
Hosts 8
Graphs 12
Data Sources Script/Command: 5
SNMP: 3
SNMP Query: 7
Total: 15

I found in PHP information that PHP SNMP is not install. Is it necessary ??

PHP SNMP Not Installed

But if you want to use cacti's cacti_snmp_* methods, cacti will check for php-snmp availability. If it's not there, cacti will switch silently to net-snmp-utils (snmpgetnext, snmpget and stuff).

So, from cacti's point of view, php-snmp is optional.

As you say, some of graphs working, so you rrdtool works fine. Problem is with returned data. You still not enable a debug mode on cacti, please go to Settings -> General and change Poller Logging Level to DEBUG. Next paste log information.
