Issue/Introduction

OI-connector seems like working partially. Inventory is being sent to DX OI SAAS, but metrics are not. Looking under the metric tree where it should show metrics form CAPC. Log is showing error: 
[WARN ] 2025-01-15 09:58:04.427 [reactor-http-epoll-4] HttpClientConnect - [<number>, L:/<IP>:55426 ! R:<apmgatewayhost and IP>:443] The connection observed an error
java.nio.channels.ClosedChannelException: null

Following command on kafka server is not showing any output.
./kafka-console-consumer.sh --bootstrap-server <kafka-ip>:9092 --topic metric-export

Environment

NetOps OI-connector integrated with DX SAAS. DX SAAS tenant
NetOps OI-connector 3.19 Installed with CA Performance Center (CAPC) version 24.3

Resolution

Added the kafka ip and enabled the configuration on Data aggregator. Opened the firewall ports on kafka server.

Now the command on kafka server seems to show that metrics are coming through.
./kafka-console-consumer.sh --bootstrap-server <kafka-ip>:9092 --topic metric-export

Metrics are also showing up in DX OI SAAS after 20/30 minutes.
