Micrometer Dynatrace
Dynatrace is a Software Intelligence Platform featuring application performance monitoring (APM), artificial intelligence for operations (AIOps), IT infrastructure monitoring, digital experience management (DEM), and digital business analytics capabilities. It can ingest multi-purpose dimensional time-series data and has built-in dashboarding. Both SaaS and self-hosted (Managed) deployments are offered.
1. Installing micrometer-registry-dynatrace
For Gradle, add the following implementation:
implementation 'io.micrometer:micrometer-registry-dynatrace:latest.release'
For Maven, add the following dependency:
<dependency>
<groupId>io.micrometer</groupId>
<artifactId>micrometer-registry-dynatrace</artifactId>
<version>${micrometer.version}</version>
</dependency>
2. Configuring
For setting up new integrations with Dynatrace, we recommend using the latest version of the Dynatrace Metrics API (currently version 2). If you use Micrometer with Spring Boot, see the Dynatrace documentation and the Spring Boot documentation. Dynatrace provides different ways of setting up integrations:
2.1. Using Dynatrace auto-configuration (preferred)
Dynatrace auto-configuration is available for hosts that are monitored by OneAgent or by the Dynatrace Operator for Kubernetes.
If Dynatrace OneAgent is installed on the host running Micrometer, metrics can be exported directly by using OneAgent without having to specify an endpoint URI or API token. If running in Kubernetes with the Dynatrace operator installed, the registry picks up your endpoint URI and API token from the operator instead. In this case, there is no need to configure anything, so you can use the following code in your project to export Micrometer metrics to Dynatrace:
DynatraceConfig dynatraceConfig = new DynatraceConfig() {
@Override
@Nullable
public String get(String k) {
// This method of the interface is used by the other configuration methods and needs to be
// implemented here. Returning null accepts the defaults for the other configuration items.
return null;
}
};
MeterRegistry registry = new DynatraceMeterRegistry(dynatraceConfig, Clock.SYSTEM);
If you use Micrometer 1.10.0 or above, you can also use the DEFAULT config to achieve the same with less code:
MeterRegistry registry = new DynatraceMeterRegistry(DynatraceConfig.DEFAULT, Clock.SYSTEM);
You can also change other properties by creating an instance of the DynatraceConfig
and overwriting the respective methods.
For example, you can specify the exporter version, which defaults to v2
unless a deviceId is set:
DynatraceConfig dynatraceConfig = new DynatraceConfig() {
@Override
public DynatraceApiVersion apiVersion() {
return DynatraceApiVersion.V2;
}
@Override
@Nullable
public String get(String k) {
return null; // accept the rest of the defaults
}
};
MeterRegistry registry = new DynatraceMeterRegistry(dynatraceConfig, Clock.SYSTEM);
DynatraceConfig
is an interface with a set of default methods.
Spring Boot’s Micrometer support binds properties prefixed with management.dynatrace.metrics.export
directly to the DynatraceConfig
.
Property names for binding attributes from Spring Boot have changed in Spring Boot version 3.0.0. If you use a Spring Boot version before 3.0.0, use management.metrics.export.dynatrace instead of management.dynatrace.metrics.export .
|
Using Spring Boot Micrometer support allows configuring the Dynatrace exporter by using the available properties.
When using Micrometer with Spring Boot, you need not instantiate the DynatraceMeterRegistry
manually, as Spring Boot does it automatically for you.
All configuration options that can be set by overwriting methods can also be set through Spring Boot properties, and adding a separate MeterRegistry can lead to metrics not being exported, as auto-configuration might break.
To use the Dynatrace metrics exporter for Micrometer in your Spring Boot project, include the runtimeOnly 'io.micrometer:micrometer-registry-dynatrace'
dependency.
In this default configuration, metrics are exported to the local OneAgent or Kubernetes operator-provided endpoint.
2.2. Using a Custom Endpoint
If auto-configuration is not available on the host, both the Dynatrace Metrics API v2 endpoint and an API token have to be specified.
The Dynatrace API token documentation contains more information on how to create an API token.
To ingest metrics, the 'Ingest metrics' (metrics.ingest
) permission is required on the token.
We recommend limiting scope to only this permission.
DynatraceConfig dynatraceConfig = new DynatraceConfig() {
@Override
public DynatraceApiVersion apiVersion() {
// not strictly required, but makes the code more clear/explicit
return DynatraceApiVersion.V2;
}
@Override
public String uri() {
// The endpoint of the Dynatrace Metrics API v2 including path, e.g.:
// "https://{your-environment-id}.live.dynatrace.com/api/v2/metrics/ingest"
String endpoint = System.getenv("ENVVAR_METRICS_INGEST_URL");
return endpoint != null ? endpoint : DynatraceConfig.super.uri();
}
@Override
public String apiToken() {
// should be read from a secure source
String token = System.getenv("ENVVAR_METRICS_INGEST_TOKEN");
return token != null ? token : "";
}
@Override
@Nullable
public String get(String k) {
return null; // accept the rest of the defaults
}
};
MeterRegistry registry = new DynatraceMeterRegistry(dynatraceConfig, Clock.SYSTEM);
These properties can also be set through Spring Boot, by using property or yaml files.
You can also reference environment variables by using the Spring property placeholders (such as management.dynatrace.metrics.export.uri: ${DT_METRICS_INGEST_URL}
).
v2 is used as the default API version unless a deviceId is set, as described below.
|
# For Spring Boot 3.0.0 and above:
management.dynatrace.metrics.export:
# For Spring Boot versions below 3.0.0, use the line below instead of the line above:
# management.metrics.export.dynatrace:
# for SaaS: https://\{your-environment-id}.live.dynatrace.com/api/v2/metrics/ingest
# for managed deployments: https://{your-domain}/e/\{your-environment-id}/api/v2/metrics/ingest
uri: YOUR_METRICS_INGEST_URL
# should be read from a secure source
api-token: YOUR_METRICS_INGEST_TOKEN
2.3. Meter metadata
Starting with Micrometer 1.12.0, the Dynatrace registry v2 exports meter metadata to Dynatrace. Currently supported types of metadata are unit (called "base unit" in Micrometer) and description. No changes are required to start exporting Metadata to Dynatrace - upgrading to version 1.12.0 or above is enough. Find more information about metrics metadata in the Dynatrace documentation.
The export of metrics metadata can be disabled by setting the exportMeterMetadata
property on the DynatraceConfig
(see the section on available properties below) to false
.
3. API Versions
3.1. API v2
When the API version is configured to v2
, the registry sends data by using the Metrics API v2.
To maintain backwards compatibility, when a deviceId
is set (which is required for v1
and not used in v2
), v1
is used as the default.
Otherwise, the version defaults to v2
and does not have to be set explicitly.
With no endpoint URI and token set, metrics are exported to the local OneAgent endpoint or, if running in Kubernetes with the Dynatrace operator installed, to the endpoint provided by the operator.
If you do not need auto-configuration, you can specify the endpoint and token explicitly, to export metrics to that specific endpoint.
Explicitly specifying these will overwrite auto-configuration.
Minimal Configuration with Dynatrace Auto-configuration
In the minimal configuration shown earlier (no URI or API token), the v2 registry tries to retrieve the endpoint provided by the Dynatrace Kubernetes operator. If the operator is not set up or does not provide this information, the exporter tries to send metrics to the local OneAgent metrics ingest endpoint. Note that this only works if a OneAgent is running on the host and the local OneAgent Metric API is available. If the ingestion port for the local OneAgent was changed to a custom one, the full endpoint URI has to be provided for the URI property (with API token left empty).
Configuration with URI and API Token
If no auto-configuration is available or the metrics should be sent to a different endpoint (such as a different tenant), you can configure the Dynatrace v2 exporter with an explicit endpoint URI and an API token.
The API token must have the "Ingest metrics" (metrics.ingest
) permission set.
We recommend limiting the scope to only this permission.
You must specify the entire Metrics v2 API endpoint URI, including its path — that is, with the /api/v2/metrics/ingest
path on SaaS and managed deployments, or /metrics/ingest
for OneAgent endpoints as mentioned in the documentation.
When using the Dynatrace metrics API v2, you can set the following properties:
DynatraceConfig dynatraceConfig = new DynatraceConfig() {
@Override
public DynatraceApiVersion apiVersion() {
return DynatraceApiVersion.V2;
}
@Override
public String uri() {
// The endpoint of the Dynatrace Metrics API v2 including path, e.g.:
// "https://{your-environment-id}.live.dynatrace.com/api/v2/metrics/ingest".
String endpoint = System.getenv("ENVVAR_METRICS_INGEST_URL");
return endpoint != null ? endpoint : DynatraceConfig.super.uri();
}
@Override
public String apiToken() {
// should be read from a secure source
String token = System.getenv("ENVVAR_METRICS_INGEST_TOKEN");
return token != null ? token : "";
}
@Override
public String metricKeyPrefix() {
// will be prepended to all metric keys
return "your.desired.prefix";
}
@Override
public boolean enrichWithDynatraceMetadata() {
return true;
}
@Override
public Map<String, String> defaultDimensions() {
// create and return a map containing the desired key-value pairs.
Map<String, String> dims = new HashMap<>();
dims.put("dimensionKey", "dimensionValue");
return dims;
}
// Only available in Micrometer 1.9.0 and above
@Override
public boolean useDynatraceSummaryInstruments() {
return false;
}
// Only available in Micrometer 1.12.0 and above
@Override
public boolean exportMeterMetadata() {
return true;
}
@Override
@Nullable
public String get(String k) {
return null; // accept the rest of the defaults
}
};
You can also set these properties in Spring Boot configuration files:
management.dynatrace.metrics.export:
# Required only if not using the OneAgent endpoint
# For SaaS: https://{your-environment-id}.live.dynatrace.com/api/v2/metrics/ingest
# For managed deployments: https://{your-domain}/e/{your-environment-id}/api/v2/metrics/ingest
uri: YOUR_METRICS_INGEST_URL
# should be read from a secure source
api-token: YOUR_METRICS_INGEST_TOKEN
# These properties can only be used with the v2 exporter.
v2:
# Sets a prefix that is prepended to each exported metric key.
metric-key-prefix: my.metric.key.prefix
# If set to true and a local OneAgent or operator is running, retrieves metadata
# and adds it as additional dimensions to all data points (default: true)
enrich-with-dynatrace-metadata: true
# Sets an arbitrary number of key-value pairs as default dimensions.
# Micrometer tags will overwrite these dimensions, if they have the same key.
# Each exported metric will contain these dimensions.
default-dimensions:
key1: "value1"
key2: "value2"
# (since 1.9.0) Whether or not to use the Dynatrace-specific summary instruments. (default: true)
# This should only be disabled if problems with existing instrumentation are discovered after upgrading to 1.9.0.
# Set to false, this will restore the previous (1.8.x) behavior for Timers and DistributionSummaries.
use-dynatrace-summary-instruments: true
# (since 1.12.0) Determines whether meter metadata (unit, description) should be exported.
export-meter-metadata: true
# The export interval in which metrics are sent to Dynatrace (default: 60s).
step: 60s
For more information about the metadata picked up by the Dynatrace metadata enrichment feature, see the Dynatrace documentation.
In Micrometer 1.9.0, Dynatrace-specific summary instruments (DynatraceTimer
and DynatraceDistributionSummary
) were introduced.
These specialized instruments are tailored to the Dynatrace metrics ingest, and prevent the creation of invalid metrics.
They are available from version 1.9.0 and are used, by default, as a drop-in replacement.
No action is needed from users upgrading to 1.9.0. If there is a discrepancy in the observed metrics, you can return to the previous behavior by setting the useDynatraceSummaryInstruments
toggle to false
.
3.2. API v1 (Legacy)
When the apiVersion
is configured to be v1
, the registry sends data by using the Dynatrace Timeseries API v1 for Custom Metrics.
If a deviceId
is specified, it defaults to v1
for backwards compatibility with earlier setups.
The device-id
property is required for v1
and not used in v2
.
Existing setups continue to work when updating to newer versions of Micrometer.
The reported metrics are assigned to Custom Devices in Dynatrace.
For the v1 API, do not specify the ingest path, but only the base URL of your environment, such as uri: {your-environment-id}.live.dynatrace.com
:
DynatraceConfig dynatraceConfig = new DynatraceConfig() {
@Override
public String uri() {
// The Dynatrace environment URI without any path, e.g.:
// https://{your-environment-id}.live.dynatrace.com
return MY_DYNATRACE_URI;
}
@Override
public String apiToken() {
// should be read from a secure source
return MY_TOKEN;
}
@Override
public String deviceId() {
return MY_DEVICE_ID;
}
@Override
@Nullable
public String get(String k) {
return null; // accept the rest of the defaults
}
};
MeterRegistry registry = new DynatraceMeterRegistry(dynatraceConfig, Clock.SYSTEM);
management.dynatrace.metrics.export:
# For v1 export, do not append a path to the endpoint URL, e.g.:
# For SaaS: https://{your-environment-id}.live.dynatrace.com
# For managed deployments: https://{your-domain}/e/{your-environment-id}
uri: https://{your-environment-id}.live.dynatrace.com
# should be read from a secure source
api-token: MY_TOKEN
# When setting the device id, metrics will be exported to the v1 timeseries endpoint
# Using just device-id (without the v1 prefix) is deprecated, but will work to maintain backwards compatibility.
v1:
device-id: sample
# To disable Dynatrace publishing, e.g. in a local development profile, use:
# enabled: false
# The interval at which metrics are sent to Dynatrace. The default is 1 minute.
