A new disk was attached to a windows server 2012. Restarted machine agent. Still the new disk not showing up in AppD under disks. Please assist.

Hello Justin,
By default, the machine agent has been configured to monitor 5 volumes. But this value is configurable.
Could you please take a look at the configuration of volumeMonitorConfig section in the $MACHINE_AGENT_HOME/extensions/ServerMonitoring/conf/ServerMonitoring.yml file? It must be looking like:
volumeMonitorConfig:
# maxNumberVolumes specifies the maximum number of volumes that the
# machine agent will monitor.
maxNumberVolumes : 5
# whitelistSelectorRegex specifies the regular expression used to whitelist reported volumes
# by name. A volume with the name matching the regex will always be reported,
# with respect to maxNumberVolumes
whitelistSelectorRegex : ""
This configuration means that the agent will show only 5 volumes by default which you see in your case. You can set a higher value to the maxNumberVolumes
parameter and then restart the machine agent to see the configured no. of volumes in your machine.
PS: Please note that as mentioned under Volume Metrics section at latest doc
There is no maximum value for maxNumberVolumes parameter in volumeMonitorConfig section in the $MACHINE_AGENT_HOME/extensions/ServerMonitoring/conf/ServerMonitoring.yml file.
You can set any value you want.
I hope this helps
Cheers,

Hi Rajesh,
Thank you for the reply to the above doubt. I would also like to know on what is the max number of volume a machine agent can observe? i.e. if a server has for example 300 Volumes/Storage disk. Will the machine agent be able to monitor them all or Does the limit end at around 50-60 volumes?
Regards,
Shashwat

I found this AppD Docs page. Search the page for "Volume" to jump to the right sections.

Thank you so much you saved me much time I thought it was an agent incompatibility issue with AWS machine but you helped solved the mystery seems to be a programming by default issue.
