Linux Partitions

[fixit2999]

When trying to monitor disk usage on a Fedora Core 4 server the snmp query within cacti only see's /dev/sda1 and /dev/sda3 partitions even though the server has other partitions on it. This happens for all FC4 boxes we are trying to monitor. How can we force cacti to see and graph the other partitions.

Hi

can you post your /etc/snmp/snmpd.conf ?

Also, what do you get when running this :

Code: Select all

$ snmpwalk -v 1 -c yourcommunity yourhost dsktable

here is the verbose query of cacti provides for Unix - Get mounted partitions

+ Running data query [6].
+ Found type = '4 '[script query].
+ Found data query XML file at '/usr/share/cacti/resource/script_queries/unix_disk.xml'

when doing the snmpwalk command the only results I get are:
END of MIB

Here is the df -h of the system
/dev/sda3 9.7G 6.1G 3.1G 67% /
/dev/sda1 487M 30M 432M 7% /boot
none 2.0G 0 2.0G 0% /dev/shm
/dev/sda6 76G 52G 21G 72% /home
/dev/sda2 15G 8.7G 5.1G 63% /var

IMO you should use the "ucd/net" data queries and graph templates.

Modify /etc/snmp/snmpd.conf like this :

Code: Select all

rocommunity public
includeAllDisks

You then will be able to graph CPU, filesystems, network, load average, etc.
