Manually Configuring EMA
EMA is based on Nagios and uses the standard Nagios configuration system for describing hosts and services to be monitored.
EMA uses the object oriented Nagios configuration by having individual configuration files that map to Ingres architectural components. These components are:
• A host system
• An Ingres installation
• Generic Ingres services
• Service checks specific to host and installation
Nagios supports multiple inheritance; EMA uses this feature extensively.
