RB800 system health OID on RouterOS 4.9

I have a RB800 which was supplied with routerOS 4.2. Using this version the command “system health print oid” worked great, however since upgrading to 4.9 this command no longer prints any results. The command does work for other oid’s such as interfaces.
I have just tested version 5 and it does the same. Has the command changed, or has it just been omitted from the OS?

In case anyone is looking for the voltage OID for battery monitoring it is 1.3.6.1.4.1.14988.1.1.3.8.0

what does

/system health print oid

show?

That command works on ROS4.2 but not on 4.9. The command seems to work, meaning it accepts it, but no results are printed.

The problem will be fixed at the next MikroTik RouterOS version.

Thank you.
