# PerfectScale data collected In order to provide service, PerfectScale collects the following data: 1. cAdvisor metrics:
```yaml container_cpu_cfs_periods_total container_cpu_cfs_throttled_periods_total container_cpu_usage_seconds_total container_memory_working_set_bytes container_network_receive_bytes_total container_network_transmit_bytes_total ``` 2. kube-state-metrics metrics:
``` kube_pod_labels kube_pod_annotations kube_pod_info kube_pod_container_status_running kube_pod_container_status_terminated kube_pod_container_status_terminated_reason kube_pod_container_status_last_terminated_reason kube_pod_container_resource_requests kube_pod_container_resource_limits kube_pod_container_status_restarts_total kube_pod_start_time kube_pod_completion_time kube_node_info kube_node_status_capacity kube_node_status_allocatable kube_node_status_condition kube_node_labels kube_pod_status_phase kube_job_owner kube_replicaset_owner kube_horizontalpodautoscaler_info kube_horizontalpodautoscaler_labels kube_horizontalpodautoscaler_spec_target_metric kube_horizontalpodautoscaler_spec_min_replicas kube_horizontalpodautoscaler_spec_max_replicas kube_horizontalpodautoscaler_status_desired_replicas kube_horizontalpodautoscaler_status_current_replicas kube_pod_container_info kube_namespace_labels kube_pod_status_reason kube_job_status_failed ``` 3. The data about containers’ spec (original) resources (spec CPU\&Memory Requests\&Limits) from `kubeapiserver`. 4. container-jvm metrics collected from coroot-node-agent:
``` container_jvm_heap_used_bytes container_jvm_heap_size_bytes container_jvm_gc_time_seconds container_jvm_info with labels extended with java VM.flags values ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.perfectscale.io/product-overview/perfectscale-data-collected.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
