This is clearly not a comprehensive monitoring tool but a simple tool to check your server about memory, network and CPU.

The client is available only for iPhone at very low price (.99$ or .79€) while server-side software is totally free.
This is what the app shows about your iPhone:

You can easily install iStat daemon on your CentOS Linux using the provided RPM:

# wget http://istatd.googlecode.com/files/istatd-0.5.4-1.el5.rych.i386.rpm
# rpm -ivh istatd-0.5.4-1.el5.rych.i386.rpm

Now you have to edit /etc/istat.conf for settings and preferences. You need to set network_port and server_code at least to have it working. iStat is able to monitor only one network interface per time through monitor_net option.
I used monitor_disk and disk_rename_label options to list the needed partitions in human readable format.
This is my config file (my code is obscured of course):

#
# /etc/istat.conf: Configuration for iStat server
#

#network_addr             127.0.0.1
network_port             5109
server_code              *****
# server_user            nobody
# server_group           nobody
# server_socket          /tmp/istatd.sock
# server_pid             /var/run/istat/istatd.pid
# cache_dir              /var/cache/istat

# Note: Only support for one network interface, limited by client.
monitor_net              ( eth2 )

# Array of disks to monitor. Specify mount path or device name.
monitor_disk             ( /dev/sda1 /dev/mapper/VolGroup00-LogVol00 )

# Set to 1 if you want to use mount path as label instead of the device name.
disk_mount_path_label    0

# Try to probe the filesystem for disk label, will override the mount path label.
disk_filesystem_label    1

# Set custom disk label. Will override all other labels.
disk_rename_label        /dev/mapper/VolGroup00-LogVol00  "RAID"
disk_rename_label        /dev/sda1      "boot"

# End of file

Don't forget to configure iptables to allow access to the choosen port.
