Problem:

Try this:

AU status on the Observability > Collectors page in the Acquisition Units tab displays "Certificate Expired” or “Certificate Revoked” .

Click on the menu to the right of the AU and select Restore Connection. Follow the instructions to restore your Acquisition Unit:

1. Stop the Acquisition Unit (AU) service. You can click the Copy Stop Command button to quickly copy the command to the clipboard, then paste this command into a command prompt on the acquisition unit machine.

2. Create a file named "token" in the c:\Program Files\Cloud Insights\Acquisition Unit\conf\ folder on the AU.

3. Click the Copy Token button, and paste this token into the file you created.

4. Restart the AU service. Click the Copy Restart Command button, and paste the command into a command prompt on the AU.

Server Requirements not met

Ensure that your Acquisition Unit server or VM meets requirements

Network Requirements not met

Ensure that your Acquisition Unit server/VM can access your Data Infrastructure Insights environment (<environment-name>.c01.cloudinsights.netapp.com) through SSL connection over port 443. Try the following commands:

ping <environment-name>.c01.cloudinsights.netapp.com
traceroute <environment-name>.c01.cloudinsights.netapp.com
curl https://<environment-name>.c01.cloudinsights.netapp.com
wget https://<environment-name>.c01.cloudinsights.netapp.com

Note that port 443 needs to be opened "outbound" from the AU to Data Infrastructure Insights.

Proxy Server not configured properly

Verify your proxy settings, and uninstall/re-install the Acquisition Unit software if necessary to enter the correct proxy settings.

1. Try "curl". Refer to "man curl" information/documentation regarding proxies: --preproxy, --proxy-* (that's a wildcard "*" because curl supports many proxy settings).
2. Try "wget". Check documentation for proxy options.

Acquisition unit installation failed in Data Infrastructure Insights with credential errors while starting acquisition service (and visible in the acq.log).

This can be caused by the inclusion of special characters in the proxy credentials. Uninstall the AU (sudo cloudinsights-uninstall.sh) and reinstall without using special characters.

Status: Heartbeat Failed

The Acquisition Unit (AU) sends a heartbeat to Data Infrastructure Insights every 60 seconds to renew its lease. If the heartbeat call fails due to network issue or unresponsive Data Infrastructure Insights, the AU's lease time isn't updated. When the AU's lease time expires, Data Infrastructure Insights shows a status of "Heartbeat Failed".

Troubleshoot steps:

* Check the network connection between the Acquisition Unit sever and CloudInsights.
* Check whether the Acquisition Unit service is running. If the service is not running, start the service.
* Check the Acquisition Unit log (<Install dir>:\Program Files\Cloud Insights\Acquisition Unit\log\acq.log) to see whether there are any errors.

I'm seeing a "Heartbeat Error: message

This error can occur if there is a network interruption that causes communication between the Acquisition Unit and the Data Infrastructure Insights environment to be interrupted for more than one minute. Verify the connection between the AU and Data Infrastructure Insights is stable and active.
