Hi kvch, Thank you for responding.. slight\_smile: There was no errors on logstash logs. I am running elasticsearch, logstash and kibana on azure linux vm and filebeat is on on-primes client server. I tried to add cloud metadata also in the filebeat.yml but throwing the error "hosting provide not detected" from client server side. Please help me if I missed any thing. thanks and regards, Uday. ---
