OMS agent can't heartbeat to Azure Monitor
I have an Ubuntu 14.04 setup in a POC environment and i've installed the Azure OMS agent on the device but it keeps getting socket bind exceptions and it can't connect to the Azure Monitor service.
I followed the steps here: https://social.msdn.microsoft.com/Forums/azure/en-US/6cc360a4-7835-4861-b122-82a43479ccf5/microsoft-monitoring-agent-is-unable-to-connect-to-loganalytics-workspace-event-id-4008?forum=opinsights
But I don't have any firewalls setup in this environment so I am not sure where the traffic is being blocked.
Here is the specific error message:
temporarily failed to flush the buffer. next_retry=2019-02-07 02:41:03 +0000 error_class="RuntimeError"
error="Net::HTTP.Post raises exception: SocketError,
'Failed to open TCP connection to redacted.ods.opinsights.azure.com:443 (getaddrinfo: Name or service not known)'"
Here's what I checked:
- Port is open on the machine directly
- Port is allowed through the VNET (allowed 443 outbound to Azure Monitor)
- No external firewall on this subnet
So I am not sure wherelse the traffic may be getting block if the port is allowed through local firewall and the subnet, and there is no firewall. Am I overlooking something else?
Edit:
Yes I redacted the hostname. I haven't specified a host name or endpoint for the monitoring agent. As far as i'm aware you don't have to. It's working on another identical box. I followed Azure's procedure to install on Linux and started the service up: https://docs.microsoft.com/en-us/azure/virtual-machines/extensions/oms-linux
I can ping google and otherwise access the internet.

(1) When you say “redacted.ods.opinsights.azure.com”, do you mean “redacted.ods.opinsights.azure.com”, or do you mean that you’re keeping your host name secret? (2) It says “getaddrinfo: Name or service not known”. That doesn’t mean that your traffic is being blocked; it means that you’ve specified an incorrect / invalid name. What have you done to verify that your name(s) are valid? E.g., can you ping it/them? … … … … … … … … … … … … … … … … … Please do not respond in comments; edit your question to make it clearer and more complete.
