Pls help me in SNMP see error below where i will get snmp php file


ERROR: opening '/www/htdocs/cacti/rra/tmpux183_snmp_oid_26.rrd': No such file or directory

Kathi,

I assume you have got the correct privileges set for the rra directory for the account running the cmd.php script. Otherwise, you will have problems updating/creating the .rrd file. By default the rra directory maybe owned by root.

another possibility is that the rrd was deleted by mistake.

Many,

Thanks for your info.

Its already priviledges there but i did ping rrd and load averages rrd on localhost but only the problem in SNMP ie trying remote host.

And alos during configuration for remote host its showing
SNMP Error..Pls help

If you only want to monitor the remote host by Advanced Ping, leave the community string for this host empty. cacti will respond with SNMP not in use. Otherwise, the remote host must respond to SNMP requests.
To check this, run

Code: Select all

snmpwalk -c <your community string> -v 1 <remote host> system

If this fails, the snmp config of that host isn't correct (or a firewall is blocking you).
If running pre-cacti-0-8.6h, set Downed Host Detection to "SNMP - Reliable". Host must show as "up" in the Devices list to be polled

The errors for both systems indicate, that SNMP was not set up correctly. You need to configure sth like /etc/snmp/snmpd.conf and start the snmpd daemon.
