Hi, I follow the guide to install bpm_analutics. My elasticsearch version is 5.4.3 .When I run the EventSummaryAgent.sh, it will always report the below error CWMCD2007I: Starting to retrieve process or activity events from the data source. CWMCD0012E: An unexpected exception was thrown when the data was retrieved.

So I check the log in the EventSummaryAgent/logs folder,the below is the error log [Jan 4, 2018 3:13:11 AM ] 0000000f SEVERE: com.ibm.bpm.mon.oi.facade.ESEventSourceFacadeImpl.querySystemIds - CWMCD0012E: An unexpected exception was thro$ org.elasticsearch.client.ResponseException: POST http://localhost:9200/bpm-events/_search: HTTP/1.1 400 Bad Request {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"Fielddata is disabled on text fields by default.

Hi, this is the ES document about this exception: https://www.elastic.co/guide/en/elasticsearch/reference/current/fielddata.html

Obviously, the bpmSystemId at your ES use the text type, but this index mapping should be created by the BPMEventEmitter, it use the keyword as the type:

"bpmSystemId": {
                    "type": "keyword"
                },

Could you run GET /your_index_name/_mapping to confirm that. If this is the case(text as the type), please:

  1. stop the BPMEventEmitter application
  2. delete the your index
  3. start the BPMEventEmitter application and check if there is any exception.
  4. get the index mapping again to see if the type change to keyword.
