|
||||
|
||||
This library provides a kafka health check for spring boot actuator.
|
||||
|
||||
== Usage
|
||||
|
||||
Add the following dependency to your `pom.xml`
|
||||
|
||||
[source,xml]
|
||||
....
|
||||
<dependency>
|
||||
<groupId>com.deviceinsight.kafka</groupId>
|
||||
<artifactId>kafka-health-check</artifactId>
|
||||
<version>1.0.0</version>
|
||||
</dependency>
|
||||
....
|
||||
|
||||
In the same maven module you can configure the topic, poll timeouts, subscription timeouts and the receive timeouts
|
||||
in the `application.yml`
|
||||
|
||||
An example for an `application.yaml` is:
|
||||
|
||||
[source,yaml]
|
||||
....
|
||||
kafka:
|
||||
health:
|
||||
topic: health-checks
|
||||
sendReceiveTimeoutMs: 2500
|
||||
pollTimeoutMs: 200
|
||||
subscriptionTimeoutMs: 5000
|
||||
....
|
||||
|
||||
The values shown are the defaults.
|
||||
|
||||
IMPORTANT: Make sure the configured health check topic exists!
|
||||
|
||||
[source,java]
|
||||
....
|
||||
@Bean
|
||||
@ConfigurationProperties("kafka.health")
|
||||
public KafkaHealthProperties kafkaHealthProperties() {
|
||||
return new KafkaHealthProperties();
|
||||
}
|
||||
....
|
||||
|
||||
[source,java]
|
||||
....
|
||||
@Bean
|
||||
public KafkaConsumingHealthIndicator kafkaConsumingHealthIndicator(KafkaHealthProperties kafkaProperties,
|
||||
KafkaProperties processingProperties) {
|
||||
return new KafkaConsumingHealthIndicator(kafkaHealthProperties, kafkaProperties.buildConsumerProperties(),
|
||||
kafkaProperties.buildProducerProperties());
|
||||
}
|
||||
....
|
||||
|
||||
Now if you call the actuator endpoint `actuator/health` you should see the following output:
|
||||
|
||||
[source,json]
|
||||
....
|
||||
{
|
||||
"status" : "UP",
|
||||
"details" : {
|
||||
"kafkaConsuming" : {
|
||||
"status" : "UP"
|
||||
}
|
||||
}
|
||||
}
|
||||
....
|
||||
|
||||
== Configuration
|
||||
|
||||
|===
|
||||
|Property |Default |Description
|
||||
|
||||
|kafka.health.topic |`health-checks` | Topic to subscribe to
|
||||
|kafka.health.sendReceiveTimeoutMs |2500 | The maximum time, in milliseconds, to wait for sending and receiving the message
|
||||
|kafka.health.pollTimeoutMs |200 | The time, in milliseconds, spent fetching the data from the topic
|
||||
|kafka.health.subscriptionTimeoutMs |5000 | The maximum time, in milliseconds, to wait for subscribing to topic
|
||||
|
||||
|===
|
||||
|
||||
== Releasing
|
||||
|
||||
Creating a new release involves the following steps:
|
||||
|
||||
. `./mvnw gitflow:release-start gitflow:release-finish`
|
||||
. `git push origin master`
|
||||
. `git push --tags`
|
||||
. `git push origin develop`
|
||||
|
||||
In order to deploy the release to Maven Central, you need to create an account at https://issues.sonatype.org and
|
||||
configure your account in `~/.m2/settings.xml`:
|
||||
|
||||
[source,xml]
|
||||
....
|
||||
<settings>
|
||||
<servers>
|
||||
<server>
|
||||
<id>ossrh</id>
|
||||
<username>your-jira-id</username>
|
||||
<password>your-jira-pwd</password>
|
||||
</server>
|
||||
</servers>
|
||||
</settings>
|
||||
....
|
||||
|
||||
The account also needs access to the project on Maven Central. This can be requested by another project member.
|
||||
|
||||
Then check out the release you want to deploy (`git checkout x.y.z`) and run `./mvnw deploy -Prelease`.

# Kafka Health Check
|
||||
|
||||
> **Note.** _forked from [deviceinsight/kafka-health-check](https://github.com/deviceinsight/kafka-health-check) due to long period of inactivity_
|
||||
|
||||
This library provides a kafka health check for spring boot actuator.
|
||||
|
||||
## Usage
|
||||
|
||||
Add the following dependency to your `pom.xml`
|
||||
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>me.bvn13.kafka.health</groupId>
|
||||
<artifactId>kafka-health-check</artifactId>
|
||||
<version>1.5.5</version>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
In the same maven module you can configure the topic, poll timeouts and the reception timeouts
|
||||
in the `application.yaml`
|
||||
|
||||
An example for an `application.yaml` is:
|
||||
|
||||
```yaml
|
||||
kafka:
|
||||
health:
|
||||
topic: health-checks
|
||||
sendReceiveTimeout: 2.5s
|
||||
pollTimeout: 200ms
|
||||
```
|
||||
|
||||
The values shown are the defaults.
|
||||
|
||||
IMPORTANT: Make sure the configured health check topic exists!
|
||||
|
||||
```java
|
||||
@Bean
|
||||
@ConfigurationProperties("kafka.health")
|
||||
public KafkaHealthProperties kafkaHealthProperties() {
|
||||
return new KafkaHealthProperties();
|
||||
}
|
||||
```
|
||||
|
||||
```java
|
||||
@Bean
|
||||
public KafkaConsumingHealthIndicator kafkaConsumingHealthIndicator(KafkaHealthProperties kafkaProperties,
|
||||
KafkaProperties processingProperties) {
|
||||
return new KafkaConsumingHealthIndicator(kafkaHealthProperties, processingProperties.buildConsumerProperties(),
|
||||
processingProperties.buildProducerProperties());
|
||||
}
|
||||
```
|
||||
|
||||
Now if you call the actuator endpoint `actuator/health` you should see the following output:
|
||||
|
||||
```json
|
||||
{
|
||||
"status" : "UP",
|
||||
"details" : {
|
||||
"kafkaConsuming" : {
|
||||
"status" : "UP"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
|
||||
| Property | Default | Description |
|
||||
|---------------------------------|-----------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
||||
| kafka.health.enabled | false | Enabling kafka health check |
|
||||
| kafka.health.topic | `health-checks` | Topic to subscribe to |
|
||||
| kafka.health.sendReceiveTimeout | 2.5s | The maximum time, given as [Duration](https://docs.spring.io/spring-boot/docs/2.1.9.RELEASE/reference/html/boot-features-external-config.html#boot-features-external-config-conversion-duration), to wait for sending and receiving the message.|
|
||||
| kafka.health.pollTimeout | 200ms | The time, given as [Duration](https://docs.spring.io/spring-boot/docs/2.1.9.RELEASE/reference/html/boot-features-external-config.html#boot-features-external-config-conversion-duration), spent fetching the data from the topic |
|
||||
| kafka.health.cache.maximumSize | 200 | Specifies the maximum number of entries the cache may contain. |
|
||||
|
||||
|
||||
|
||||
## Releasing
|
||||
|
||||
Creating a new release involves the following steps:
|
||||
|
||||
1. `./mvnw gitflow:release-start gitflow:release-finish`
|
||||
2. `git push origin master`
|
||||
3. `git push --tags`
|
||||
4. `git push origin develop`
|
||||
|
||||
In order to deploy the release to Maven Central, you need to create an account at https://issues.sonatype.org and
|
||||
configure your account in `~/.m2/settings.xml`:
|
||||
|
||||
```xml
|
||||
<settings>
|
||||
<servers>
|
||||
<server>
|
||||
<id>ossrh</id>
|
||||
<username>your-jira-id</username>
|
||||
<password>your-jira-pwd</password>
|
||||
</server>
|
||||
</servers>
|
||||
</settings>
|
||||
```
|
||||
|
||||
The account also needs access to the project on Maven Central. This can be requested by another project member.
|
||||
|
||||
Then check out the release you want to deploy (`git checkout x.y.z`) and run `./mvnw deploy -Prelease`.

# KafkaHealthCheck
|
||||
|
||||
## Version 1.5.3
|
||||
|
||||
* Added SpringBootAutoConfiguration
|
||||
|
||||
## Version 1.5.2
|
||||
|
||||
* Changed maven group publication: switched into `me.bvn13.kafka.health`
|
||||
|
||||
## Version 1.4.0
|
||||
|
||||
* Got rid of `subscriptionTimeout` as a redundant timeout
|
||||
|
||||
## Version 1.3.0
|
||||
|
||||
* Health check timeouts can now be configured in `java.time.Duration` format. The timeouts can still be configured using
|
||||
millisecond values (`long`) as well to stay compatible with old configurations.
|
||||
* Dependency versions are now managed by `spring-boot-dependencies`. [ISSUE-17](https://github.com/deviceinsight/kafka-health-check/issues/17)
|
||||
* As of now, cache metrics can be exposed. For this purpose, a corresponding MeterRegistry instance must be passed
|
||||
when instantiating the Kafka Health Check. [ISSUE-20](https://github.com/deviceinsight/kafka-health-check/issues/20)
|
||||
* The cache size can now be configured via the property `kafka.health.cache.maximum-size`. The default value for the cache size is 200. [ISSUE-22](https://github.com/deviceinsight/kafka-health-check/issues/22)
|
||||
* Filtering messages that do not come from the same instance. [ISSUE-24](https://github.com/deviceinsight/kafka-health-check/issues/24)
|
||||
|
||||
## Version 1.2.0
|
||||
|
||||
* Reduce logging level of health check calls to `TRACE`.
|
||||
|
||||
## Version 1.1.0
|
||||
|
||||
* Make consumer groups unique by appending a random UUID when no group ID is configured explicitly.
|
||||
* Refactor health check strategy: Kafka polled continuously.
|
||||
|
||||
## Version 1.0.0
|
||||
|
||||
* Develop kafka health check
