You have an application hosted on a Compute Engine virtual machine instance that cannot communicate with a resource outside of its subnet. When you review the flow and firewall logs, you do not see any denied traffic listed.
During troubleshooting you find:
• Flow logs are enabled for the VPC subnet, and all firewall rules are set to log.
• The subnetwork logs are not excluded from Stackdriver.
• The instance that is hosting the application can communicate outside the subnet.
• Other instances within the subnet can communicate outside the subnet.
• The external resource initiates communication.
What is the most likely cause of the missing log lines?
You are troubleshooting an application in your organization's Google Cloud network that is not functioning as expected. You suspect that packets are getting lost somewhere. The application sends packets intermittently at a low volume from a Compute Engine VM to a destination on your on-premises network through a pair of Cloud Interconnect VLAN attachments. You validated that the Cloud Next Generation Firewall (Cloud NGFW) rules do not have any deny statements blocking egress traffic, and you do not have any explicit allow rules. Following Google-recommended practices, you need to analyze the flow to see if packets are being sent correctly out of the VM to isolate the issue. What should you do?
You have created an HTTP(S) load balanced service. You need to verify that your backend instances are responding properly.
How should you configure the health check?
