error starting Camunda-Monitoring

[fernandoscruz]

I am making a mistake when going up the camunda monitoring.

Can someone help me?

My conf default.yml: spring.datasource: url: jdbc:mysql://mysql:3306/process-engine driver-class-name: com.mysql.cj.jdbc.Driver username: camunda password: "xxxxxx"

Based on the error above you need to set your default.xml to have the same history level as your db. The DB config says history level is 0.

see: https://docs.camunda.org/manual/latest/user-guide/spring-boot-integration/configuration/#camunda-engine-properties

config: camunda.bpm.history-level

I'm sorry for the inconvenience, but it's still unclear where I should fix it.

What should I include in the default.xml file?

Thank you very much

@StephenOTT

I believe I have found a bug.

When including "TRACE_LEVEL_FILE = 0; DB_CLOSE_ON_EXIT = FALSE" in the URL configuration, unknown database error:

ERROR 9 --- [main] org.camunda.bpm.engine.cfg: ENGINE-12012 Exception on accessing the database connection: Unknown database 'camunda_mysql_azul; TRACE_LEVEL_FILE = 0; DB_CLOSE_ON_EXIT = FALSE'

When removing "TRACE_LEVEL_FILE = 0; DB_CLOSE_ON_EXIT = FALSE" from the configuration, historylevel error:

configuration says HistoryLevelFull (name = full, id = 3) and database says HistoryLevelNone (name = none, id = 0)

My complete setup is:

spring.datasource: url: jdbc: mysql: //camundamys-01-xxxx.dev.mysql.xxxxxx.com: 3306 / camunda_mysql_azul; TRACE_LEVEL_FILE = 0; DB_CLOSE_ON_EXIT = FALSE driver-class-name: com.mysql.cj.jdbc.Driver username: u_prometheus password: Xxxxxxx

Thanks

Did you set your default.yml to have the property: camunda.bpm.history-leve: NONE?

are you familiar with Java and/or springboot?

[fernandoscruz]

Hi @StephenOTT

I don't have much affinity for Java and / or springboot.

I'll explain my plan to you.

I currently have a camunda in production and I would like to export metrics to prometheus, and I discovered your project.

I use a similar project to connect to gitlab and export metrics, I imagine your project has the same goal.

So, I used your project to start a new application that connects to the existing camunda database.

I'll post all the settings in the dockerfile and default.yml, in case you can help me.

Thank you very much.
