Java Virtual Machine
This document describes how to collect JMX metrics exposed by Java applications for long-term retention and monitoring in Axibase Time Series Database.
This integration enables both performance monitoring (garbage collection, load, threads, heap/offheap memory), availability monitoring (system uptime counter), as well as configuration tracking by notifying of any changes in the system properties.
Enable JMX in Java Application
Configure your Java application for JMX data collection as described by the JMX Job Documentation.
Import JVM Job into Axibase Collector
- On the Jobs page, select Import from the split button at the bottom of the page and upload the jmx-jvm-job.xml file.
Configure JMV JMX Connection
- Open the Jobs menu and select JMX. Click the
- For each JMX Configuration:
- Provide connection parameters to the target JVM:
- Click Test:
Schedule the Job
- Open the JMX Job page and click Run for the JVM JMX job.
- Make sure that the job status is
COMPLETEDand Items Read and Sent commands are greater than 0.
- If there are no errors, set the job status to Enabled and save.
Verify Metrics in ATSD
- Log in to ATSD.
- Click on Metrics tab and filter metrics by name
Viewing Data in ATSD
- List of collected JVM metrics.
- List of collected JVM properties.
- Open Settings menu and click Entity Groups, select Import from the split button, and upload
- Select the imported
- Verify that the group contains your JVM hosts.
- Open the Entity Views menu and select Configuration, click Import, and upload
- Select the imported
- Select the Entity Group that you created earlier.
- Click View and browse information about your entities:
- Open the Portals menu and select Configure, click Import, and upload
- Click the Assign link and associate the portal with the entity group you created earlier.
- Open the Entity tab, find the java application by name, and click the Portal icon:
Setting up Mail Client
- Configure Mail Client.
- Open the Alerts menu and select Rules, click Import, and upload
- For each created rule: open the rule in the Rule Editor and change recipient address on the Email Notifications tab.
- These rules automatically apply to all JVM-based applications monitored by Axibase Collector.
|jvm_application_restart||Raise an alert when an application has been restarted less than 5 minutes ago.|
|jvm_cpu_load||Raise an alert when an application cpu load exceeds the set threshold.|
|jvm_garbage_collection_rate||Raise an alert when an application Garbage Collector rate exceeds the set threshold.|
|jvm_garbage_collection_time||Raise an alert when an application Garbage Collector time exceeds the set threshold.|
|jvm_heap_memory_usage||Raise an alert when an application heap memory usage exceeds the set threshold.|
|jvm_runtime_property_changed||Raise an alert when an application property is changed.|
|jvm_system_load||Raise an alert when an application system load exceeds the set threshold.|
To create your own rules, refer to Rule Engine documentation.
