如何使用 kql 查询查找哪个 pod 在 AKS 集群中摄取更多数据？

Question

I am trying to figure out which pod is producing more billable data ingestion in AKS for log analytics.

I tried several queries and I found only a query that checks the particular node

Is there any query to check the whole pod data ingestion per namespace to find out billable data ingestion?

Thank you?

The default query shows logs per container, and not per pod as you would expected from a Kube.netes-specific logging system.

You can use below KQL query in Log Analytics Workspace -> View Designer -> click on logs button in the header->Logging AKS Test->Container Log.

let startTimestamp = ago(1h);
KubePodInventory
| where TimeGenerated > startTimestamp
| project ContainerID, PodName=Name
| distinct ContainerID, PodName
| join
(
    ContainerLog
    | where TimeGenerated > startTimestamp
)
on ContainerID
// at this point before the next pipe, columns from both tables are available to be "projected". Due to both 
// tables having a "Name" column, we assign an alias as PodName to one column which we actually want
| project TimeGenerated, PodName, LogEntry, LogEntrySource
| order by TimeGenerated desc
