Elastic Reconciliation Report for Failed Events - 

Server - ST2(microservice was running in 45)

Targetted Events - {"addIndividual","addOrganization","addPartyRole","addSubscriber","createBatchOrder","createCustomerOrder","enrichAddon","enrichAttribute","enrichPayer","enrichUser","orderLineCease","terminatePartner","updateCustomerOrder","updatePartyRole","updatePartyRoleByAssocId","updateSalesOrder","updateSubscriber","orderCompletion","updateAccount","updateCustomer","updateOrderLines","createOrder","addContact","addCustomer","addAccount","updateOrder"}

Daily Average Failure Count = 200-400

Observations - Some times the failure count is around 3000-5000 due to service failures like Kafka down or else EventEnricher Failure

Reason for Events Failure in Microservice - While kafka trying to send the message with the key and payload provided Specifically, it says "Expiring 16 record(s) for salesorder.reconstruct.request-0:120000 ms has passed since batch creation." This indicates that the Kafka producer attempted to send a batch of 16 records related to the salesorder.reconstruct.request topic but was not able to complete it within the allowed time (120000 ms).
