Monitoring setup on Supported systems without OpenTelemetry Collector

Using nevisAdmin4 without OpenTelemetry Collector, Prometheus and Grafana can be used for logging Product Analytics metrics for the components.

Installation​

OpenTelemetry agent​

Download nevis-opentelemetry-javaagent-<version>.jar from the Nevis portal and save it as /opt/agent/opentelemetry-javaagent.jar

Setup​

During generation, nevisAdmin4 creates the otel.properties file which should look similar to this example: 

otel.service.name = <service-name>
otel.traces.exporter = none
otel.metrics.exporter = none
otel.logs.exporter = none

For Java based components, to use the OpenTelemetry agent, nevisAdmin4 extends the JAVA_OPS of the relevant component with:

JAVA_OPTS=(
    "-javaagent:/opt/agent/opentelemetry-javaagent.jar"
    "-Dotel.javaagent.logging=application"
    "-Dotel.javaagent.configuration-file=/var/opt/<service-name>/default/conf/otel.properties"
    "-Dotel.resource.attributes=service.version=<version>,service.instance.id=<intanceId>"
)

where

  • service-name: Name of the service, e.g.: nevisidm
  • version: Version of the service, e.g.: 1.0
  • intanceId: Name of the instance, such as idm-dev
info

The ProductAnalytics metrics are logged in every 24 hours to the application's standard log file.
