Built-in incidents

The table provides an overview of the built-in incident rules in the Self-Monitoring and Custom System Profiles.

Severity Name Description System Profile
Severe Agent Instrumentation Disabled
Reasons for that include: Collector has performance issues, Agent response time is very slow or has poor instrumentation performance.
It is not possible to instrument the Agent. Self-Monitoring & Custom
Severe Agent Capturing Disabled The Agent did not send updates for an extended period of time and was disabled. Self-Monitoring
Warning Ambigous Agent Mapping The Agent could be mapped to several System Profiles. Self-Monitoring
Severe Continuous transaction recording was cencelled The server is no longer recording PurePaths to disk, probably due to a problem such as out of disk space or file system error. Self-Monitoring & Custom
Severe Custom events When you right-click in a chart dashlet and select Heat Field > Add Custom Events you can mark a Custom time period in the heat field to highlight a maintenance or other event in the chart. Self-Monitoring & Custom
Severe Collector not connected (unexpected) Connection to a previously connected Collector was lost.
This incident also appears in the Start Center.
Self-Monitoring
Warning Conflicting Agent JVM Options Raises incidents for conflicting JVM options Self-Monitoring
Warning Dynatrace Server Offline Signals normal termination of Dynatrace Server. Self-Monitoring
Severe Dynatrace Server Offline (unexpected) Signals normal termination of Dynatrace Server. Self-Monitoring
Informational AppMon Server Online Signals abnormal termination of Dynatrace Server. Self-Monitoring
Severe File Session Management Session storage-related incidents. For example, disk quota exceeded or corrupted sessions detected. Self-Monitoring
Severe License License-related incidents, such as an expiring license.
This incident also appears in the Start Center.
Self-Monitoring
Severe Low Collector Memory Agent-related incidents caused by Collector heap memory, such as the Agent's instrumentation being disabled automatically to free some memory. Self-Monitoring
Severe Low AppMon Server Memory Low (non-heap) server memory. Self-Monitoring
Severe Number of Measures The number of measures reached the maximum of 300,000, which is likely caused by a misconfigured Business Transaction. Self-Monitoring
Severe Performance Warehouse Triggered by Performance Warehouse related events. Self-Monitoring
Severe Performance Warehouse Offline Connection to Performance Warehouse could not be established. This incident also appears in the Start Center. Self-Monitoring
Severe Performance Warehouse - Switching Temp Tables Time Triggered when the insert and switch procedure of the measurement heap tables lasts longer than the default severe threshold. Self-Monitoring
Severe Performance Warehouse - Writing Measurements Time Writing of measurements into heap tables takes longer than the severe threshold. Self-Monitoring
Warning Performance Warehouse - Writing Measurements Time Writing of measurements into heap tables takes longer than the warning threshold. Self-Monitoring
Severe Performance Warehouse - Writing Percentiles Time Writing of percentiles into the percentiles table takes longer than the severe threshold. Self-Monitoring
Warning Performance Warehouse - Writing Percentiles Time Writing of percentiles into percentiles tables takes longer than the warning threshold Self-Monitoring
Severe Port Conflict A port used for communication on the AppMon Server could not be opened. Self-Monitoring
Informational Repository Clean-Up Triggered when writing time is slow. Self-Monitoring
Warning Scheduled Task Execution Failed A scheduled task has failed. Self-Monitoring
Informational System Profile Changed The system profile configuration has been changed. Custom
Informational Agent Connected Raises incidents for individual connected agents. Custom
Informational Agent CPU Time Capturing The Agent disabled CPU time capturing because overhead was too high. Adjust the capturing options in the Agent Group's Sensor configuration. Custom
Informational Agent Hot Sensor Placement Triggered when the Agent is Hot Sensor placed. Custom
Severe Application Process Out-of-memory Memory snapshot triggers, unless it is disabled in the Advanced Settings of the Agent Group mapping. Custom
Severe Application Process Unavailable (unexpected) A previously connected application process was shut down. Custom
Severe Continuous Transaction Recording was cancelled   Custom
Warning Corrupted PurePath(s) Raises incidents for PurePaths that are corrupted. Self-Monitoring & Custom
Warning High CPU Usage for Application Process High CPU usage detected for a longer period. Custom
Warning High GC Activity for Application Process A large amount of process time used for garbage collection. Custom
Warning High Memory Usage for Application Process Memory usage is at a high percentage for a long time period. Custom
Severe High Overall Failed User Action Rate The user action rate exceeds the configured threshold. Custom
Severe High Overall Failed Transaction Rate The failed transaction rate exceeds the configured threshold. Custom
Severe Response Time Degraded for Slow Requests The response time of slow transactions has changed. Custom
Informational Session Cleared Clear Session was executed. Custom
Informational Test Violation The test result has changed significantly: degraded, improved, failed, or is volatile. Custom
Warning Timed Out PurePath(s) Either a method has not returned or a whole child path did not finish within a certain time. Custom
Warning Truncated PurePath(s) PurePath(s) have been truncated because their size exceeds the node limit. Custom
