Metric event data with an invalid metric value cannot be indexed. How to troubleshoot

[Anuj]

I'm trying to fetch windows perfmon data using below input stanza but not receiving any data and I could see the error in splunk messages.

input.conf

[perfmon://LogicalDisk]
counters = Free Megabytes;% Free Space
instances = *
interval = 30
mode = single
object = LogicalDisk
index = em_metrics
_meta = os::"Microsoft Windows Server 2012 R2 Standard" os_version::6.3.9600 entity_type::Windows_Host
useEnglishOnly = true
sourcetype = PerfmonMetrics:LogicalDisk
disabled = 0

Error Message

The metric value=<unset> is not valid for source=LogicalDisk, sourcetype=LogicalDisk, host=******, index=em_metrics. Metric event data with an invalid metric value cannot be indexed. Ensure the input metric data is not malformed.

The metric name is missing for source=LogicalDisk, sourcetype=LogicalDisk, host=********, index=em_metrics. Metric event data without a metric name is invalid and cannot be indexed. Ensure the input metric data is not malformed.

Splunk Enterprise is 8.0.3

Forwarders tried are 7.3.6, 8.0.3, 8.0.4  

Can anyone help here please?

Is it a distributed environment? If it is make sure you have installed the Splunk_TA_windows on the SH andINX(if you are using UFs)
