MQL question for time series

[Ross G]

Hi, is anyone able to assist with this MQL?

I am able to run this query using the UI - It is Kubernetes Pod -> Pod -> Bytes Received grouped by Service Name

That works

However I am not able to get the equivalent MQK

Trying this

fetch k8s_pod

| metric 'kubernetes.io/pod/network/received_bytes_count'

| group_by [metadata.system.service_name]

| align rate(1m)

| every 1m

Line 3: Expression for time series identifier column 'metadata.system.service_name' had type 'Set(String)' which is not a valid time series identifier column type.
