MSExchange Transport Database Internal Free Space for Performance monitoring

[Cwohechler]

Looking for guidance on adding a new Windows performance counter, \MSExchangeTransport Database\Transport Queue Database Internal Free Space (MB). to Zabbix for monitoring. I have added the following to the Zabbix Agent on the Windows Exchange Server (Windows Server 2016, Exchange 2016):
PerfCounter = TransportQueueDBFreeSpace, "\MSExchangeTransport Database(queue)\Transport Queue Database Internal Free Space (MB)", 60

Saved the file and restarted the Zabbix agent. I went to the zabbix web site, selected the host, items, create new items. I put TransportQueueDBFreeSpace in the Key field, updated Title and tried to test and get "Invalid Performance Counter Path" I then tried to select a key for windows performance and enter this for the key: perf_counter_en[TransportQueueDBFreeSpace,60] same error.

Any help would be greatly appreciated!

I found the correct format for the performance monitor. This is what I used for the key in the item:
perf_counter_en["\MSExchangeTransport Database(_total)\Transport Queue Database Internal Free Space (MB)"]

The Data is measured in MBs, and I am polling every 60 seconds.
