Java is the most commonly used object oriented programming languages to build critical, highly scalable internet solutions on top of the Java Virtual Machine (JVM). In addition to custom business applications, many mission critical microservice systems such as Cassandra and Hadoop are written in Java. Instana’s Java Monitoring offers comprehensive performance and health management for any and all applications / services written in Java.
To understand and optimize application performance and further automate performance management workflows, Instana’s automatic Java Monitoring goes beyond simple metrics to provide a comprehensive set of management and monitoring features:
- Discovery of JVM instances
- Zero configuration health monitoring
- Automatic tracing of HTTP service endpoints
- Automatic code instrumentation for supported technologies (e.g. Spring Boot, Apache Tomcat, and others)
- Visualization of service dependency maps
- Tracing of all end-to-end requests across all systems and services
- Automated application and service discovery
Comprehensive Java Monitoring requires performance visibility for the physical or virtual host, containers, JVM instances, typical JVM metrics (like Garbage Collection data), and any application and service code deployed into the JVM instance.
Instana is the quickest and easiest way to monitor Java based services across the stack to deliver comprehensive application insights. The Instana agent automatically discovers all JVM instances, deploys the necessary monitoring sensors and begins tracing applications and requests. Instana also automatically determines not only the health of the JVM instances, but also for applications and services running inside.
Monitoring Java Performance
Once deployed, the Instana Agent automatically identifies all running Java instances – then deploys and configures Instana’s Java Monitoring sensor without any manual effort, as well as additional sensors for technologies used in the Java applications running inside the JVM. Instana’s curated knowledge base already knows what performance metrics are relevant for collection and how to collect them. To monitor Java services health, additional metrics are also collected. Since Instana’s automatic configuration collects all relevant information, monitoring Java instances couldn’t be easier.
To determine overall service health, the Instana Java Monitoring sensor also collects KPIs on the monitored JVM-running environment to determine its health status.
With the help of Artificial Intelligence (AI) and health signatures from the curated knowledge base, Instana automatically detects issues with individual Java instances and and issues service incidents. Based on severity, Instana automates incident escalation and root cause identification, helping you solve issues before users are impacted.
Java Monitoring Data
Instana Java Monitoring includes two types of data; Performance Metrics and Health Signatures:
|Java Performance Data||Java Health Signatures|
|GC Activity||Code Cache|
|Memory Usage||PermGen / MetaSpace Size|
|Memory Pools||GC Activity|
|Threads||Heap Size and Usage|
Additional metrics are acquired based on technologies and frameworks deployed into the JVM instances.
Further information on the different sensor information is available in the
Instana Java Management Documentation.
