Application Type - Jvm¶
JVM Application is a application that can run jvm processes. Because Onteon knows the type of the process, it can automatically do some actions like resize the memory on errors or create thread and memory dumps for later analyzing. You need to specify start command and executable file, which could be a jar file.

successLine: 'Spring Boot properly started'
makeActionOnMemoryOverflow: true
maxActionOnMemoryOverflow: 5

isExternal: true
isInternal: true
Configuration keys¶
app.name¶
Name of application.
app.version¶
Version of application.
app.type¶
Application type. It should be set to standard.
Possible values:
- standard - Standard application.
- embedded - Application used for internal purposes, such as edge balancer.
- unknown - Unknown application.
app.procType¶
Process type. It should be set to native.
Possible values:
- native - Native application.
- docker - Docker application.
- unknown - Unknown application.
app.processProvider.name¶
Name of process provider. It should be set to JVMOsProcessProviderImpl.
Possible values:
- GenericOsProcessProviderImpl - for native processes.
- JVMOsProcessProviderImpl - for native JVM processes.
- DockerOsProcessProviderImpl - for docker processes.
app.processProvider.version¶
Version of process provider. It should be set to 1.0.0.
app.processProvider.version.executable.start.path¶
Path to directory with executable.
app.processProvider.version.executable.start.startJvmCommand¶
Command to start JVM process.

app.processProvider.version.executable.start.increasePercentageOnMemoryOverflow¶
How much more (in terms of percentage) memory should be assigned for process.
app.processProvider.version.executable.start.xms¶
Value of JVM parameter xms.
app.processProvider.version.executable.start.xmx¶
Value of JVM parameter xmx.
app.processProvider.version.executable.start.cpus¶
CPUs limit for process.
app.processProvider.version.executable.start.memory¶
Memory limit for process.

Placeholder name.
app.placeHolder.version¶
Placeholder version.
app.placeHolder.filesToReplace¶
List of files that will have placeholder replaced.
app.placeHolder.variables¶
Placeholders variables in key-value format.
app.serviceRepository.healthCheckUrl¶
Url that will determine if application is alive.
app.serviceRepository.entities¶
List of service repository entities.
app:
serviceRepository:
