https://docs.camunda.org/optimize/latest/technical-guide/setup/configuration/#logging 

In the above docs we incorrectly say  "OPTIMIZE_LOG_LEVEL sets the logging level for Elasticsearch", this environment variable should be corrected to "ES_LOG_LEVEL". Also make sure to check if this needs backported.

AT:

• The env variable correctly reads ES_LOG_LEVEL instead of OPTIMIZE_LOG_LEVEL
• This change is backported if required
