Breaking changes

Java Code-level RVA/RAP reach GA

Application Security | Vulnerabilities

Code-level Vulnerability Analytics for Java and Application Protection for Java have been released to General Availability (GA).

This affects the settings schema builtin:appsec.runtime-vulnerability-detection. Additional values are required for:

  • enableCodeLevelVulnerabilityDetection (true / false),
  • globalMonitoringModeJava ("MONITORING_ON", "MONITORING_OFF")

New features and enhancements

New DQL command parameter

Platform | DQL

The new rollup parameter for the timeseries DQL command triggers all metric series for a given timeframe that are aggregated. Then the specified rollup parameter is selected from the series and aggregated further according to the given aggregation.

For details, see timeseries.

New DQL commands

Platform | DQL

Now you can include the following commands in your DQL queries:

  • fieldsKeep
    The fieldsKeep command keeps the selected fields.

  • describe
    The describe command describes the on-read schema extraction definition for a given data object.

New DQL functions

Platform | DQL

Now you can include the following functions in your DQL queries:

  • unixNanosFromTimestamp
    The unixNanosFromTimestamp function can be used to convert a timestamp into nanoseconds since Unix epoch.

  • unixMillisFromTimestamp
    The unixMillisFromTimestamp function can be used to convert a timestamp into milliseconds since Unix epoch.

  • unixSecondsFromTimestamp
    The unixSecondsFromTimestamp function can be used to convert a timestamp into seconds since Unix epoch.

  • getDayOfMonth
    The getDayOfMonth function can be used to extract the day of the month from a timestamp.

  • getDayOfWeek
    The getDayOfWeek function can be used to extract the day of the week from a timestamp.

  • getDayOfYear
    The getDayOfYear function can be used to extract the day of the year from a timestamp.

    The getHour function can be used to extract the hour from a timestamp.

  • getMinute
    The getMinute function can be used to extract the minute from a timestamp.

  • getSecond
    The getSecond function can be used to extract the minute from a timestamp.

  • getYear
    The getYear function can be used to extract the year from a timestamp.

  • getWeekOfYear
    The getWeekOfYear function can be used to extract the week of the year from a timestamp.

  • punctuation
    The punctuation function can be used to extract punctuation characters out of input strings.

  • levenshteinDistance
    The levenshteinDistance function can be used to compute the distance between two input strings.

  • arraySort
    The arraySort function is used for sorting array elements.

  • isIp
    The isIp set of functions can be used to check if an expression is an IP address.

  • ipMask
    The ipMask function can be used to mask an expression with given bits.

  • ipIn
    The ipIn function can be used to check if a list of IP addresses or an IP network contains particular IP addresses.

  • ip
    The ip function can be used to create an IP address.

  • toIp
    The toIp function can be used to convert an expression to an IP address.

  • IP address mathematical functions
    The IP address mathematical functions can be used to add or subtract numerics or IP addresses.

  • arrayReverse
    The arrayReverse function returns the array with elements in reversed order.
  • replaceString
    The replaceString function replaces each substring of a string with a given string.
  • arrayRemoveNulls
    The arrayRemoveNulls function returns the array where NULL elements are removed.

Platform | DPL Latest Dynatrace

DPL Architect now provides a variety of preset patterns for the most popular technologies in the field, such as AWS, Microsoft, and GCP. You can access them in Saved patterns > Dynatrace patterns. For faster access, they are logically divided into a folder structure.

New attacks metric

Application Security | Attacks

Keep an eye on the number of attacks over time with the New attacks metric. For details and use cases, see Application Security metrics.

Monitoring mode settings schema change

Infrastructure Monitoring | Hosts

The fullStack property in the builtin:host.monitoring schema has been replaced with the monitoringMode property in the new builtin:host.monitoring.mode schema. The new property is a string type with possible values of "FULL_STACK" and "INFRA_ONLY".

This change not only affects the API but also is reflected in the GUI - the monitoring mode selection is now on a separate tab.

For the API use, the previous version of the builtin:host.monitoring schema is still available and will continue to be supported. Therefore, the simplest way to adapt existing automations to this change is to specify "schemaVersion": "1.0.0" in the payload for write operations.

Read operations can't specify a schema version, so automations that read the monitoring mode will need to be adapted to use the new schema.

This change doesn't affect the OneAgent on a host API, only the Settings API.

Linux ARM64 support for log module

Infrastructure Monitoring | Logs

Starting with this release, OneAgent log module is fully supported by ARM64 CPU architecture.

Usage details for Dynatrace Platform Subscription

Platform | DPS

With this release, we introduced new metrics to help you understand and analyze the consumption of all Dynatrace capabilities via the Dynatrace Platform Subscription (DPS) license model.

To find these metrics in Data Explorer, type DPS into the Search field. You can query data for the following DPS capabilities via DQL:

  • Automation Workflow
  • AppEngine Functions - Small
  • Log Management and Analytics – Query
  • Events - Query

Background color of SLO tiles

Automation | SLO

A new toggle, Colorize based on status, is now available for SLO tiles.

If enabled, the background color of the SLO tile reflects the SLO status.

Host monitoring mode settings schema

Infrastructure Monitoring | Hosts

The fullStack property in the builtin:host.monitoring schema has been replaced with the monitoringMode property in the new builtin:host.monitoring.mode schema.

  • The new monitoringMode property has a string type with possible values of "FULL_STACK" and "INFRA_ONLY".
  • The builtin:host.monitoring schema is still available and will continue to be supported. To adapt existing automations to this change, specify "schemaVersion": "1.0.0" in the payload for write operations. Read operations can't specify a schema version, so automations that read the monitoring mode will need to be adapted to use the new schema.

This change doesn't affect the OneAgent on a host API, only the Settings API.

Cluster

  • Vulnerability: Improved security by disallowing the specification of a 'Host' header in Problem notification settings of type `Custom Integration` or `xMatters`. (DAVIS-5099)
  • Vulnerability: An extension configuration that uses owner-only credentials now can only be created and updated by the owner of the credentials. (EXT-5195)
  • Baselining events now also generate event markers in unified services screens. (DAVIS-5186)
  • An extension definition can now include more than one screen actions section per entity type. (TI-7075)
  • Alerting profile property filters properly support read-only properties now (for example, dt.event.impact_level). (DAVIS-5001)
  • Changed the base for the Memory usage chart to Memory used. (HOST-3158)
  • Creating a custom attribute named "content" no longer causes issues with Log Monitoring Classic queries. (LOG-3871)

ActiveGate

  • The Kubernetes Pod CPU/memory requests/limits metrics now hold the effective resource value, as this has a higher relevance for Pod scheduling. The Pod's effective request/limit for a resource is the higher of (1) the sum of all app containers' request/limit for a resource and (2) the effective init request/limit for a resource. (K8S-6178)

managed

  • Improved password reset process for local users in cases involving partial Single Sign-On (SSO) integration. (CLD-7086)

sepl agent/activegate stream

  • Fix an issue with the 'OneAgent in a host group' API where manual update to a specific version in some cases did not work. (CLUSTER-7190)

Update 98 (Build 1.271.98)

This is a cumulative update that contains all previously released updates for the 1.271 release.
