Due to the backend changes, for container monitoring with OMS Agent for Linux and it is a fresh install, you will need to run this workaround.

If this a fresh install, install the agent and onboard later by doing the following steps:

1. Download the OMS Agent for Linux. Install the OMS Agent for Linux.

   sudo ./omsagent*.sh --install

2. Onboard your OMS workspace.

   sudo /opt/microsoft/omsagent/bin/omsadmin.sh -w <wsid> -s <key>

If you have already installed and onboarded, re-onboard by doing the following steps:

1. Remove all the onboarded OMS workspace.

   sudo /opt/microsoft/omsagent/bin/omsadmin.sh -X

2. Re-onboard your OMS workspace.

   sudo /opt/microsoft/omsagent/bin/omsadmin.sh -w <wsid> -s <key>
