6.4 HATS HA Remote Monitoring System


HATS HA Remote Monitoring System makes it convenient for a system administrator to monitor the status of HATS HA
from a remote machine. This feature is especially useful when the servers are located in a public place where the system
administrator cannot monitor HATS HA privately. With this feature, the system administrator can now sit in a private
office and never loses control of HATS HA.

In order to use the HATS HA Remote Monitoring System, your machine must be connected through either LAN or
WAN to the other machines running HATS HA and must have HATS HA installed. However, it does not need a license
number.

You also need to modify the configuration to use the HATS HA Remote Monitoring System. The following examples
show you both the configuration for running one NFS job without using the HATS HA Remote Monitoring System and
the modified configuration for running one NFS job using the HATS HA Remote Monitoring System.

  1. Configuration for running one NFS job without using the HATS HA Remote Monitoring System:

      Notes:
    1. In this example, the hostname for the machine used for remote monitoring is "leroy", and all the added lines
      are in bold.
    2. In /etc/hosts, you also need to enter the IP and hostname for "leroy" in each machine that will be remotely
      monitored. In the "leroy" machine, you need to enter all the IP and hostnames for all the machines that you'd
      like to monitor.
