Overview

iStat is a great iPhone application you can use to monitor a (dv) Dedicated-Virtual Server. Here are the following steps to configure your (dv) server for iStat.

Temperatures and fans are not yet supported on Linux servers.

Requirements

Before you start, this article has the following dependencies:

Instructions

Download the latest version of the istat for linux from http://github.com/tiwilliam/istatd.

wget http://github.com/downloads/tiwilliam/istatd/istatd-0.5.4.tar.gz

Extract the package:

tar -zxvf istatd-0.5.4.tar.gz
cd istatd-0.5.4

Configure and build. You MUST make sure you have the Developer Tools installed:

./configure --prefix=/usr --sysconfdir=/etc
make
make install

Create a new user account for the program so it can run in a shielded environment:

useradd istat -s /sbin/nologin
mkdir -p /var/{cache,run}/istat
chown istat /var/{cache,run}/istat

Start the service:

/usr/bin/istatd -d

Create a script to restart service upon reboot, and add the following lines:

vi /etc/init.d/istatreboot.sh

Next, let's make the script executable.

chmod +x /etc/init.d/istatreboot.sh

Start istatd upon reboot/startup:

/usr/bin/istatd -d

Edit the /etc/rc.local file:

vi /etc/rc.local

Add /etc/init.d/istatreboot.sh to the bottom of the script. Edit the istat.conf, and change the server code to a new 5 digit number of your choosing (default is 12345):

vi /etc/istat.conf

You will also want to change the following two lines monitor_net, and monitor_disk, to match what is provided in the example istat.conf file:

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

# network_addr           127.0.0.1
# network_port           5109
server_code              12345
# server_user            istat
# server_socket          /tmp/istat.sock
# server_pid             /var/run/istat/istat.pid
# cache_dir              /var/cache/istat

monitor_net              venet0
monitor_disk             ( /dev/vzfs )

Now, restart istatd:

/usr/bin/istatd -d

Done. Now setup your iPhone/iPod Touch to connect.
