Memory percentage is the Memory utilization that occurred on the container level where your instance traffic is load balanced. If the instance traffic is managed over multiple DCs, each DC's container's memory utilization is provided. Usually there is one primary container that is handling most of the load and others are in standby mode. ## Memory Utilization (max) {#io-load-balancer__section_k2r_krw_jjc} Absolute value of Memory Utilization that has been utilized at a given time. ## CPU Utilization (1 to 100 max) {#io-load-balancer__section_cdr_krw_jjc} CPU Utilization is the percentage of CPU capacity that has been utilized at a given time. CPU percentage is the CPU utilization that occurred on the container level where your instance traffic is load balanced. If the instance traffic is managed over multiple DCs, each DC's container's CPU utilization is provided. Usually there is one primary container that is handling most of the load and others are in standby mode. ## CPU Utilization (max) {#io-load-balancer__section_ecr_krw_jjc} Absolute value of CPU Utilization that has been utilized at a given time. ## 2xx Responses (Success) Rate 5 mins {#io-load-balancer__section_dbr_krw_jjc} Total number of http responses/second with response code 2XX (successful response to a http request) that the server has sent over the last 5 minutes. Note that this is an aggregated value that includes all responses sent for the instance in question. The rate 5 mins is calculated based on two data points within the last 5 minutes window divided by time lapsed between them. For more information on 2xx responses, see . ## 5xx Responses (Failure) Rate 5 mins {#io-load-balancer__section_f1r_krw_jjc} Total number of HTTP responses/second with response code 5XX (server error response to a HTTP request) that the server has sent over the last 5 minutes. Note that this is an aggregated value that includes all responses sent for the instance in question. The rate 5 minutes is calculated based on two data points within the last 5 minutes window divided by time lapsed between them. For more information on 5xx responses, see . ## Load balancer active (processing) HTTP requests {#io-load-balancer__section_rzq_krw_jjc} This represents the total number of active (processing) requests at a given timestamp. Note that this is an aggregated value that includes all responses sent for the instance in question. **Related reference** * [Anomaly insights](https://servicenow-prod.fluidtopics.net/4_QeeoMptTF3e9qrg4XWwg "The reference topic gives additional information for anomaly charts.") * [Feature availability based on package](https://servicenow-prod.fluidtopics.net/P9qjLGc3vCF_cOO3tzGPpA "The table outlines the access permissions for Performance Analytics features across production and sub production instances.") * [Auriga Intelligent Alert report](https://servicenow-prod.fluidtopics.net/nQSJ7KPMZhRA30JC0WUapA "Auriga Intelligent Alert is an advanced multivariate machine learning (ML) model that learns from historical issues on your instance to provide real-time insight.
