Azure AKS Logging

Question

Hi Team,

We have a customer running multiple custom applications generating app logs in different formats & different timestamps. All the apps are currently running in Mirantis Kuberenes Engine and using ELK stack (File beat + Log stash + Elastic search + Kibana) to Extract & visualize the logs.

Now customers are planning to migrate all the custom apps into Azure and run containers from AKS. We have recommended enabling monitoring and using container insight from Azure monitor blade to troubleshoot the logs from Portal. However we're not sure whether Azure Monitor supports ingest app logs from different formats and how custom log aggregation is going to be handled in Azure.

Could you through some idea on app logging in AKS from above use case ?

Any support / recommendation is highly appreciated.

Hello @Boopathy, Elango ,

Azure Monitor/Container Insights can ingest stdout/stderr coming from any container to Log Analytics and can have rich query and correlation experience.
If the customer is looking for instrumenting and forwarding logs to a log store without forwarding it to stdout/stderr, please refer Application insights offering from Azure monitor.
