Ensure Availability of Servers with Dynamic IP Addresses

If you select DHCP when installing a single-server CA Enterprise Log Manager, specify the hostname (not the IP address) of that CA Enterprise Log Manager when installing each agent. This will ensure that any DHCP-reassignment of the IP address of the CA Enterprise Log Manager server will not impact the agents that use it.

If you specify the IP address of the CA Enterprise Log Manager server when installing the agents and that dynamic IP address changes, you will need to reinstall the agents to restore the availability of the single-system CA Enterprise Log Manager server. To avoid this potential problem, we recommend you install an additional CA Enterprise Log Manager server and add it as a secondary server for all agents. This will ensure high availability of servers.
