Munin on CentOS 6 - Problems Disk graphs

[jmjosebest]

Hi,

I have many servers with CentOS 6 and all runs Ok, but I have installed a new one and Disk graphs are not generated. Empty graphs.

Disk IOs per device
Disk latency per device
Disk throughput per device
Disk utilization per device
IO Service time

Test: ​http://176.31.226.229/munin/cluster006/cluster006/index.html

The procedure to install Munin is:

• Install CentOS base
• Install EPEL repo
• Install munin munin-node

iostat run Ok

[root@cluster006 munin]# iostat config
Linux 2.6.32-131.0.15.el6.x86_64 (cluster006) 12/15/2011 _x86_64_ (8 CPU)

avg-cpu: %user %nice %system %iowait %steal %idle

0.75 0.15 0.29 0.04 0.00 98.78

Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn

[root@cluster006 munin]#

Thanks to check
