Cacti SNMP - Getting "value: U" although there is a value available

Vote count:

I've followed the guide on the following forum to get postfix logs graphed in cacti: http://ift.tt/1651lN0

(See the fifth post)

The installation steps on the post is as follows:

1) Configure SNMP agent on Mail server and make sure it is set up right.

2) Unzip fetch_mail_statistics.pl script in place of your choice. (I used /usr/local/bin)

3) Check that your perl path in script points to perl executable

4) Add following line in snmpd.conf file Code: pass .1.3.6.1.4.1.2021.255 /usr/local/bin/fetch_mail_statistics.pl /var/log/mail.log /var/log/mailstats.db .1.3.6.1.4.1.2021.255

5) Adjust your maillog filename and path corresponding to your system. mailstats.db are used for internal script data storage, place it anywhere. 6) Import template in cacti.

When I run the following command from the terminal, I'm able to get values and graph postfix in cacti:

/usr/local/bin/fetch_mail_statistics.pl /var/log/mail.log /var/log/mailstats.db .1.3.6.1.4.1.2021.255 -g .1.3.6.1.4.1.2021.255.9

Although when I added the the configuration to snmp.conf (See step 4) I'm only getting "value: U" and nAn in cacti.

I've checked permissions and I ran the script manually as the snmp-user (sudo -u snmp "code-here") without problems. We graph other stuff which works so there aren't any configuration problems with snmp or cacti.
