These events are either in ready or queued states, ready is the start of the processing life cycle and queued means they have already been claimed by an event processor. These metric values should remain relatively low. If the value gets too high, it is likely to indicate a processing delay. ## Events Processed Delta {#io-events-performance-metrics__section_k5p_y2x_hjc} This represents the delta change in the number of events that are in a processed state since the previous data collection point (i.e., in the previous 2 seconds). These events have fully processed by the event processor. If the events processed delta is at zero, then it means that the queue has nothing further to process or there has been a failure in the event processor. ## Event Queue Backlog Delta {#io-events-performance-metrics__section_pdt_1fx_hjc} This represents the delta change in the number of events unprocessed (increasing or decreasing backlog ) since the previous data collection (that is, in the previous 2 minutes). ## High Priority (HIPR) Events Backlog {#io-events-performance-metrics__section_if4_2fx_hjc} This represents the total number of unprocessed events that were high priority. These high priority events are either in ready or queued states, ready is the start of the processing lifecyle and queued means they have already been claimed by an event processor. These metric values should remain relatively low. If the value gets too high, it is likely to indicate a processing delay. ## High Priority (HIPR) Events Processed {#io-events-performance-metrics__section_qmk_3fx_hjc} This represents the delta change in the number of high priority events that are in a "processed" state since the previous data collection point (that is, in the previous 2 seconds). These high priority events have fully processed by the event processor. If the high priority events processed delta is at zero, then it means that the queue has nothing further to process or there has been a failure in the event processor. **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.
