What is changing?  

When customers enable Container Insights, Azure Monitor deploys a containerized collection agent. This agent is being renamed from OMSAgent to Azure Monitor Agent. There are no feature updates or functional changes to the agent in this release.  

Why are the changes being made? 

The current OMSAgent name is a legacy name from the OMS product and does not reflect the branding for Azure Monitor and Container Insights products. The Azure Monitor Agent is being standardized as the single collection agent for Azure Monitor. The name change brings the agent’s name in line with these updates.  

When are the changes going live? 

The changes will roll out region by region starting from early September.  Exact dates and a version number of Container Insights image version with changes will be shared closer to the release date with an update to this blog post.

AKS customers will receive the changes as part of an AKS service update. Arc and Hybrid customers will have to update their extension and HELM chart versions manually. See detailed instructions below.

What are the exact changes? 

The agent used by Container Insights has been renamed. So, customers will see a new pod name in their clusters. Alongside that, several other related resources have also been renamed. See the “List of renamed resources” and “List of renamed labels " tables below for complete details.  

What is the impact? What do I need to do?  

Log analytics queries  

All log queries with string the omsagent in them will not work and results will only be returned for dates before the change. To mitigate, update the queries to have query clause to cover “omsagent” or “ama-logs” in existing queries. See examples below.  

 
 

Original query 

Updated query 

KubePodInventory 

| where Namespace == "kube-system" 

| where Name contains "omsagent" 

 

KubePodInventory 

| where Namespace == "kube-system" 

| where Name contains "omsagent" or Name contains “ama-logs” 

 

 

Original query 

Updated query 

ContainerLog 

| where Name contains "omsagent" 

 

ContainerLog  
| where Name contains "omsagent" or Name contains "ama-logs"  
 

 

Alert Rules 

Alert Rules with the string the omsagent will not work.  

  1. Query alerts with the string “omsagent” 
  1. Metric alerts which reference omsagent in a dimension   

You can find alert rules using  

Option 1 – In the Alerts section of Azure Monitor in the Azure portal

Option 2 - Programmatically using Azure Resource Graph queries  

Go to the “Azure Resource Graph Explorer” in the portal and run the below query:  
 
alertsmanagementresources 

| where properties contains"omsagent" 

 

The above steps should help you find the affected rules. To update the rules, simply edit them in the portal (as below).

User scripts  

Any user scripts explicitly referencing the pod names will not work.

  

Resource name in all UIs  

Customers will see the updated controller names in the Container Insights UI as well as the command line.
