Installation requirements and recommendations

The Service Impact server requires a host with the following features:

  • Red Hat Enterprise Linux or CentOS Linux, version 6 (Starting with Service Impact 5.1.5, RHEL/CentOS 5 is no longer supported on the Service Impact server host)
  • 4 GB main memory
  • 8 CPU cores
  • 50 MB disk space for software
  • 50 MB disk space for log files
  • 1-20 GB disk space for database files

This release of Service Impact requires Java 1.8. The installation procedure describes how to install OpenJDK 1.8 on a dedicated Service Impact server host, and Oracle Java 1.8 for co-located deployments on a Resource Manager master host.

Deployment strategies

Service Impact is packaged for a dedicated-host deployment, and as such, Zenoss recommends installing it on a separate, dedicated host system. In addition, installing Service Impact on a dedicated system avoids contention with Resource Manager core services and allows for improved performance.

Installing the Service Impact server on the Resource Manager master host can be appropriate for development and testing environments, and in very limited cases, production environments. If you are unsure which deployment strategy is best for your environment, consult Zenoss Support.

Zenoss also recommends choosing a network location for the Service Impact host that enables low-latency SSH and API access from the Resource Manager master host. The zenimpactstate daemon runs on the Resource Manager master host and communicates directly with the Service Impact server.

Optionally, you may mount a separate filesystem for the Service Impact server database.
