Unable to start Telegraf service appearing in log messages

Hello,

I have Azure monitor agent installed on a Ubuntu VM in Azure eastus and I'm seeing a lot of error messages in the log files, should I be concerned about these errors ?

`root@markstestVM1205Thu:/var/log/azure# cat /etc/lsb-release

I'm seeing the following error

Start with the reported telegraf.log and extension.log entries on the Ubuntu 18.04 Azure VM, including the missing /var/run/mdsd/default_influx.socket and metrics-sourcer.service references. Determine whether the Telegraf startup failure is reproducible and what repository change or documented resolution is expected; the issue currently provides no acceptance criteria or named source file.
