Nevermind, I managed to get the example working
https://ignite.apache.org/docs/ignite2/latest/monitoring-metrics/tracing#enabling-trace-sampling
with spring boot 4.1.0 for transaction.
It would be great if the documentation gets updated on how to setup
(register) the Tracing Bridge to OLTP (GlobalOpenTelemetry) to export
ignite tracing to a system like the grafana-lgtm stack (
https://grafana.com/docs/opentelemetry/docker-lgtm/)
I've created a lifecycle bean to instruct ignite tracing after the node
start:
@Component
class IgniteLifecycleBean : LifecycleBean {
@IgniteInstanceResource
private lateinit var ignite: Ignite
override fun onLifecycleEvent(evt: LifecycleEventType) {
if (evt == LifecycleEventType.AFTER_NODE_START) {
afterNodeStart()
}
}
private fun afterNodeStart() {
ignite.tracingConfiguration().set(TracingConfigurationCoordinates.Builder(Scope.TX).build(),
TracingConfigurationParameters.Builder().withSamplingRate(1.0).build())
}
}
I've configured the lifecycle bean in my config and register the
GlobalOpenTelemetry:
@Configuration
class IgniteConfig {
@Bean
fun ignite(openTelemetry: OpenTelemetry, lifecycleBeans:
List<IgniteLifecycleBean>): IgniteSpringBean {
registerGlobalOpenTelemetry(openTelemetry)
val ignite = IgniteSpringBean().apply {
configuration = IgniteConfiguration().apply {
igniteInstanceName = "my-ignite-instance"
igniteHome = Paths.get(".").toAbsolutePath().toString()
gridLogger = Slf4jLogger()
metricsLogFrequency = 0
tracingSpi = OpenCensusTracingSpi()
discoverySpi = TcpDiscoverySpi().apply {
localAddress = "127.0.0.1"
localPort = 47500
localPortRange = 20
ipFinder = TcpDiscoveryVmIpFinder().apply {
setAddresses(listOf("127.0.0.1:47500..47520"))
}
}
communicationSpi = TcpCommunicationSpi()
setLifecycleBeans(*lifecycleBeans.toTypedArray())
}
}
return ignite
}
private fun registerGlobalOpenTelemetry(openTelemetry: OpenTelemetry) {
if (!GlobalOpenTelemetry.isSet()) {
GlobalOpenTelemetry.set(openTelemetry)
}
}
}
I've used these dependency:
plugins {
kotlin("jvm") version "2.4.10"
kotlin("plugin.spring") version "2.4.10"
id("org.springframework.boot") version "4.1.0"
id("io.spring.dependency-management") version "1.1.7"
}
ext["opentelemetry.version"] = "1.64.0"
val igniteVersion = "2.18.0"
dependencies {
implementation("org.springframework.boot:spring-boot-starter-opentelemetry")
implementation("org.springframework.boot:spring-boot-starter-webmvc")
implementation("org.jetbrains.kotlin:kotlin-reflect")
implementation("tools.jackson.module:jackson-module-kotlin")
implementation("io.opentelemetry.instrumentation:opentelemetry-logback-appender-1.0:2.29.0-alpha")
implementation("io.opentelemetry:opentelemetry-exporter-otlp")
implementation("io.opentelemetry:opentelemetry-opencensus-shim:1.64.0-alpha")
implementation("io.micrometer:micrometer-tracing-bridge-otel")
implementation("org.apache.ignite:ignite-spring:$igniteVersion")
implementation("org.apache.ignite:ignite-slf4j:$igniteVersion")
implementation("org.apache.ignite:ignite-opencensus:$igniteVersion")
developmentOnly("org.springframework.boot:spring-boot-docker-compose")
testImplementation("org.springframework.boot:spring-boot-starter-opentelemetry-test")
testImplementation("org.springframework.boot:spring-boot-starter-webmvc-test")
testImplementation("org.jetbrains.kotlin:kotlin-test-junit5")
testRuntimeOnly("org.junit.platform:junit-platform-launcher")
}
And somewhere in my code it is invoking:
private val cacheConfiguration = CacheConfiguration<Int,
String>().apply {
name = "MyCache"
atomicityMode = CacheAtomicityMode.TRANSACTIONAL
}
fun transaction(): String {
val cache = ignite.getOrCreateCache(cacheConfiguration)
val transactions = ignite.transactions()
transactions.txStart().use {
cache.put(1, "test value")
logger.info(cache.get(1))
cache.put(1, "second value")
it.commit()
}
return "transaction successful"
}
