Hello Team, I really enjoyed working with Metricbeat and jolokia together to get my application Mbeans. Below is my module configuration from metricbeat.yml In this I have one static Mbean name which will never get changes but I have a dynamic Mbean : 'com.app:name=JobDetailedDiagnostics- **APT/KMN/FACILITY**' which gets changed everytime I restart my server. ## Below are my questions: 1. I understand Jolokia exposes dynamically created Mbeans but from metricbeat side, how do i configure dynamically created Mbeans? 2. I have around 100+ Mbeans. I want to push all the Mbean information. So is there any way like jmx.mappings: all so that it would fetch all the available Mbeans? (In this case I dont need to worry about Dynamically created Mbeans too as everything will be pushed regardless of dynamic or static) - module: jolokia metricsets: ["jmx"] period: 10s hosts: ["[http://localhost:8280/jolokia-war-1.6.0/](http://localhost:8280/jolokia-war-1.6.0/)"] namespace: "n4metrics" username: "tomcat" password: "\*\*\*\*\*\*" jmx.mappings: - mbean: 'com.app:name=SystemHealthDiagnostics' attributes: - attr: ActiveSessions field: ActiveSessions - attr: NumberOfSlowQueries field: NumberOfSlowQueries - attr: ActiveDatabaseConnections field: ActiveDatabaseConnections - attr: SlowQueriesTimeFrameInMillis field: SlowQueriesTimeFrameInMillis - attr: SystemActive field: SystemActive - attr: Description field: Description - mbean: 'com.app:name=JobDetailedDiagnostics- **APT/KMN/FACILITY**' attributes: - attr: LocallyScheduledJobs field: LocallyScheduledJobs - attr: LocallyExecutingJobs field: LocallyExecutingJobs - attr: AllDiagnostics field: AllDiagnostics - attr: LocallyScheduledJobCount field: LocallyScheduledJobCount - attr: LocalExecutingJobCount field: LocalExecutingJobCount - attr: MaxThreadPoolCount field: MaxThreadPoolCount - attr: Description field: Description .......... .......... .......... ---

Hi @Kathir_J, Before proceeding further I want to clarify some terminology first. > [@Kathir\_J](#): > > In this I have one static Mbean name which will never get changes but I have a dynamic Mbean : 'com.app:name=JobDetailedDiagnostics- **APT/KMN/FACILITY**' which gets changed everytime I restart my server. When you say "dynamic Mbean" are you referring to the dynamic naming of the class, i.e. `JobDetailedDiagnostics-*`. Or are you referring to the concept of classes implementing the `DynamicMBean` interface, as shown here: [https://docs.oracle.com/cd/E19206-01/816-4178/6madjde4l/index.html](https://docs.oracle.com/cd/E19206-01/816-4178/6madjde4l/index.html)? ---

Yep.. I meant dynamic naming of the class. Anyways I found out that with \* search, able to retrieve the dynamically created Mbean attributes. Thanks anyways. My 2nd question was to include all Mbeans without mentioning Mbean names under jmx mappings? something like, module: jolokia metricsets: ["jmx"] period: 10s hosts: ["[http://localhost:8280/jolokia-war-1.6.0/](http://localhost:8280/jolokia-war-1.6.0/)"] namespace: "n4metrics" username: "tomcat" password: "\*\*\*\*\*\*" jmx mappings: \* Is there a way? ---

We don't support something like `jmx.mappings: *` because it could lead to a potential explosion of fields in Elasticsearch, depending on the number of MBeans and the number of attributes in each. It's something we could consider, though. If you are on GitHub, please file an issue for this request here: [https://github.com/elastic/beats/issues/new](https://github.com/elastic/beats/issues/new). That way you'll be notified of any discussions and progress. If you aren't on GitHub, let me know and I'll file the issue for you. ---
