I am looking to get the CPU and memory from a particular container instance… I can find the container details using builtin:kubernetes.containers and filter for the one I need I ideally want to run builtin:containers.cpu.usageMilliCores but in order to get the right container I need the container\_group\_instance value I am not sure how to find out this information, can anyone assist? ---

Not sure what you want to get, builtin:containers.cpu.usageMilliCores also accepts container as filter condition. Can you please further explain your need? BR ---

Hey thanks for the response… we have multiple containers with the same name as they are in different environments… So I am using this query builtin:containers.cpu.usageMilliCores:filter(eq(Container,vehicle-ohs)):names:parentsthis gives me multiple results…But I only want to use the container returned with this querybuiltin:kubernetes.containers:filter(eq(“k8s.deploymentconfig.name”,“vehicle-ohs”),eq(“k8s.namespace.name”,“vrm-e2e”),eq(“container\_state”,“running”)):names:parentsBut I cannot find out which container group this is in? ---

Hi[@stephenje](https://community.dynatrace.com/user/23732) you can tag the container on creation to be able to identify it. ---

Thanks [@DanielS](https://community.dynatrace.com/user/35788) can those tags be used in a filter? ---

Hi, if you want to filter only a single container of a specific namespace you can leverage on relationships like this: builtin:containers.cpu.usageMilliCores :filter(in(“dt.entity.container\_group\_instance”, entitySelector(“type(~“CONTAINER\_GROUP\_INSTANCE~”),fromRelationships.isCgiOfNamespace(type(CLOUD\_APPLICATION\_NAMESPACE),entityName.equals( **\** ))”))) :splitBy():sort(value(auto,descending)):limit(20) or by referencing the namespace by id builtin:containers.cpu.usageMilliCores :filter(in(“dt.entity.container\_group\_instance”, entitySelector(“type(~“CONTAINER\_GROUP\_INSTANCE~”),fromRelationships.isCgiOfNamespace(type(CLOUD\_APPLICATION\_NAMESPACE),entityId( **\** ))”))) :splitBy():sort(value(auto,descending)):limit(20) In general usage of relationships when dealing with k8s entities is very useful. See: [Monitored entities API - GET all entity types | Dynatrace Docs](https://www.dynatrace.com/support/help/dynatrace-api/environment-api/entity-v2/get-all-entity-types) [Environment API v2 - Entity selector | Dynatrace Docs](https://www.dynatrace.com/support/help/dynatrace-api/environment-api/entity-v2/entity-selector) Hope this helps Paolo ---

Yes, you can reference it by using, type(“CONTAINER\_GROUP\_INSTANCE~”),tag(“[context]key1:value-1”,“key2:value-2”,“value-3”) ---
