Description
On a Linux (centos 7.9.2009) vm, when event hub access is unavailable (via firewall rule, or other) the diagnostic agent consumes 100% cpu. In this state, logs will contain many things such as:
2020-09-25T23:24:53.3588310Z: MDSCMD Error: EH publish to https://....servicebus.windows.net/eventhub/messages failed: Failed to read HTTP status line
2020-10-07T19:10:22.8354670Z: MDSCMD Error: EventPersistMgr::ProcessFileData failed to upload file X2Jec5
2020-10-07T19:10:22.8371300Z: MDSCMD Error: EH async publish to https://....servicebus.windows.net/eventhub/messages failed with http response: Error resolving address
In this scenario, it would be nice if the VM could remain stable. Is there any config setting or change I could make to alleviate this? Thank you.
