PowerDNS get statictics with Cacti on CENTOS 7

[kim88]

Hello everyone,
Please, I faced and issue with snmwalk using cacti to monitor PowerDNS.
I add the the following to snmpd.conf
extend pdns-rec /usr/bin/pdns_stats
I also put the pdns_stats file in /usr/bin where the rec_control file and the other are installed.

but when I try to run the following command : snmpwalk -v 2c -c public localhost .1.3.6.1.4.1.8072.1.3.2.4.1.2 , I get that error

Code: Select all

NET-SNMP-EXTEND-MIB:nsExtendOutLine."pdns-rec".1 =STRING:FATAL:Unable to bind to local temporary file
NET-SNMP-EXTEND-MIB:nsExtendOutLine."pdns-rec".1 =No more variables left in this MIB View (It is past the end of the MIB tree )

I am using :
*Centos 7
*php 5.4.16
*httpd-2.4.6
*cacti1.1.12
*powerdns 4.0.4

Please, can someone help me?

Thank You
