System requirements

System requirements of web applications (/monitor and /monitor-analytics)

Java Runtime Environment

  • OpenJDK (JDK or JRE), versions 11*, 17

  • Oracle JDK, versions 11*, 17

Java 17 Note

When using Java 17, the following Java option must be added for Apache Tomcat:

--add-opens=java.base/java.net=ALL-UNNAMED

Application server

  • Apache Tomcat 9.0

Make sure a recent version of Apache Tomcat is installed, accepting HTTPS connections at e.g. https://tomcat-host. HTTPS can be configured as described in the Tomcat User Guide .

Operating system

  • Windows

  • Linux

Database (only Monitoring)

  • Oracle Database 18c*, 19c

  • Microsoft SQL Server 2019*, 2022

  • PostgreSQL 13*, 14

Browser

Latest stable version:

  • Google Chrome

  • Firefox

  • Microsoft Edge

  • Safari

General Hints

  • Versions marked with * might be replaced in one of the next releases in favor of a newer one.

  • In case you have platforms other than those listed preceding, contact con terra support .

System requirements Elasticsearch

The products Elasticsearch and Logstash receive, process and store the collected events so that they can then be subjected to targeted research and analysis in Kibana.

Currently, these versions are required:

  • Elasticsearch 7.17.x (OS , Java )

  • Logstash 7.17.x

  • Kibana 7.17.x

Full overview of Elasticsearch system requirements .

For security and distribution reasons, it is recommended that you run these components on a separate host, independent of the application infrastructure.

Compatibility with other con terra products

User interaction data collection in map.apps applications.

All map.apps line 4 applications can be enabled to send user interaction data through service.monitor bundles.

User interaction data collection in map.apps (server)

Currently, integration data for logging user interaction data with the server components of map.apps is available between map.apps version 4.7.0 and 4.13.

User interaction data collection security.manager EE

Currently integration data for logging user interaction data with the server components of security.manager EE between version 4.15 and 4.19 are available.

Single-Sign-On (SSO) with security.manager EE

To ensure the highest possible level of security, please always use the latest security.manager version if the login in the /monitor webapp is to be switched to security.manager authentication.

Architectural Considerations

Here are some basic recommendations you may follow when setting up service.monitor.

  • Run service.monitor applications separately from your applications - if your application server fails completely you are going to recognize this too late

  • Separate Elasticsearch and Logstash from your internet exposed applications - these are performing memory and cpu consuming operations.

  • Run Elasticsearch cluster with at least two nodes or be at least prepared for growing requirements

Memory and hard disk memory

The Elasticsearch components require resources for operation. The more data that needs to be processed, stored and searched, the more generously the system must be dimensioned. It does not make sense to stay below the minimum values mentioned here. However, the recommended values are only a recommendation based on current customer setups known to us. The operation of the Elasticsearch cluster must therefore be accompanied during the commissioning phase, especially with regard to these resource requirements. Index Lifecycle Management is used to ensure long-term operation.
