How to Create Observable Integration Solutions Using WSO2 Enterprise Integrator Chanika Geeganage and Lahiru Madushanka Integration Team 1
Agenda • Introduction to observability in WSO2 Enterprise Integrator • Observability for integrations • Observability for business processes • Observability for messaging • Extending EI Analytics 2
Introduction
Importance of Observability • Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs. • Observability helps in – Decision making and building incident preparedness – Identifying constrained resources and forecasting growth – Helping reduce the cycle of fire fighting within teams 4
Introduction to Observability in WSO2 EI • Events • Logs • Tracing • Java Management Extensions (JMX) 5 Business / Operational Insight 5 Applications Services and systems Improvements / Modifications Existing Services Identify erroneous incidents Monitoring requests count Trace messages WSO2 Enterprise Integrator Monitor Infrastructure utilization
Observability for Integrations
ESB Event Monitoring with EI Analytics 7 Thrift Data Agent Thrift Data Receiver Real Time Events Dashboard Storage Analyze Summarize Worker Portal
Aggregations over long time periods • Incremental aggregation for – every second, minute, hour, … , year • Support for out of order event arrival • Fast data retrieval from memory and disk 8 Current Min Current Hour Sec Min Hour 0 - 1 - 5 ... - 1 - 2 - 3 - 4 - 64 - 65 ... - 2 - 124
Prerequisites for EI Analytics • To enable mediation statistics and message tracing, <EI_HOME>/conf/synapse.properties 9 Property Name Description mediation.flow.statistics.enable Enables statistics for the selected ESB artifact(s). mediation.flow.statistics.tracer.collect.payloads Enables tracing for the selected ESB artifact(s) and records message payloads. mediation.flow.statistics.tracer.collect.properties Enables tracing for the selected ESB artifact(s) and records message context (transport) properties. mediation.flow.statistics.collect.all Enables mediation statistics for all the artifacts in the ESB profile by default.
Prerequisites for EI Analytics cont. • To publish data from the ESB profile to EI analytics profile, <EI_HOME>/repository/deployment/server/eventpublishers/MessageFlowConfigurationPublisher.xml <EI_HOME>/repository/deployment/server/eventpublishers/MessageFlowStatisticsPublisher.xml 10 Property Name Description username The username to be used when accessing the WSO2 EI Analytics server to publish configurations. password The password to be used when accessing the WSO2 EI Analytics server to publish configurations. receiver URL The URL of the thrift port to which the EI configurations should be published. The format of the URL is as follows. tcp://<localhost>:<THRIFT_PORT>
Enabling Statistics/Tracing for Individual Artifacts 11
Real-time Analytics • Process events as and when received • Default Siddhi App consists of Siddhi queries, input, and output streams 12 -- if DecompressedEventStream's componentType is ProxyService or API or InboundEndPoint, add it into PreProcessedESBStatStream from DecompressedEventStream[componentType == "proxy service" or componentType == "api" or componentType == "inbound endpoint"] select componentId, componentName, componentType, duration, ifThenElse(faultCount > 0, 1, 0) as faultCount, startTime, entryPoint, metaTenantId insert current events into PreProcessedESBStatStream;
Monitoring ESB Profile with Analytics Dashboard • ESB profile statistics overview • Statistics for proxy services • Statistics for sequences • Statistics for REST APIs • Statistics for endpoints and inbound endpoints • Statistics for mediators and messages 13
How to Create Observable Integration Solutions Using WSO2 Enterprise Integrator
Data Purging • By default enabled in Siddhi App • Defined using @purge @store(type = 'rdbms', datasource = 'EI_ANALYTICS') @info(name = 'MediatorStat') @purge(enable='true', interval='60 min', @retentionPeriod(sec='1 day', min='72 hours', hours='90 days', days='1 year', months='2 years', years='3 years')) define aggregation MediatorStatAgg from PreProcessedMediatorStatStream select metaTenantId, entryPoint, entryPointHashcode, componentId, hashCode, componentName, componentType, sum(duration) as totalDuration ,avg(duration) as avgDuration, min(duration) as minDuration, max(duration) as maxDuration, count() as noOfInvocation, sum(faultCount) as faultCount, startTime group by metaTenantId, componentId, componentName, componentType, entryPoint, entryPointHashcode, hashCode aggregate by startTime every sec...years;
Observability for Business Processes
Monitor via BPMN-Explorer • Historical information of process instances
Monitor via BPMN-Explorer Cont. • Supports advanced filtering 18
Generate Reports via BPMN-Explorer • Process Instance Count • Average Time Duration Of Completed Processes • Task Durations Of Completed Process • User Vs Number Of Tasks Completed • User Vs Average Time Taken to Complete Tasks • Task Instance Count Variation Over Time • Process Instance Count Variation Over Time • User Performance Of Tasks Instances Over Time
Generate Reports via BPMN-Explorer Cont.
Observability for Messaging
Broker-Specific MBeans • JMX monitoring on following MBeans using JConsole or other third party monitoring tool. (AppDynamics) 22 Property Name Description ClusterManagementInformation MBean Cluster specific attributes. MessageStatusInformation MBean Retrieve the lifecycle status of the messages in the store to a specific Excel sheet. QueueManageInformation MBean Queue specific attributes and operations. SubscriptionManageInformation MBean Subscription specific operations.
Message Metrics 23 Messaging Metrics Views ● Disruptor ● Publish and Subscribe ● Messages and acknowledgements ● Database
JVM Metrics 24 JVM Metrics Views ● CPU ● Memory ● Threading ● Class Loading ● File Descriptor
Extending EI Analytics
JMX Monitoring • WSO2 Enterprise Integrator exposes a number of management resources as JMX MBeans which helps to monitor the running server. • To monitor statistics relating to artifacts that are deployed in the EI server Mediation Flow Statistics View Mbean can be used. 26
How to Create Observable Integration Solutions Using WSO2 Enterprise Integrator
Customize Statistics Publishing • A custom statistics observer can be created by implementing org.wso2.carbon.das.messageflow.data.publisher.observer.MessageFlowObserver interface. 28 public class MyStatisticsObserver implements MessageFlowObserver { //Invoked when this observer is notified public void updateStatistics(PublishingFlow publishingFlow) { //Process data } } <MediationFlowStatisticConfig> <Observers> org.wso2.custom.MyStatisticsObserver </Observers> </MediationFlowStatisticConfig> ● Add all custom observers as a comma separated list in the <EI_HOME>/conf/carbon.xml.
EI logs Monitoring with Elastic Stack • Setting up Filebeat to read log files from EI. • Update filebeat-yaml with the path to EI logs folder. • Setting up Logstash to take the log lines from Filebeat, convert them to JSON strings, and ship them to Elasticsearch. • Setting up Elasticsearch to store and search logs. • Setting up Kibana to monitor EI. 29
ESB Statistic Monitoring with ElasticStack • Custom message flow observer implemented to publish EI statistics to ElasticStatisticPublisher. 30
Kibana Visualization 31
Kibana Visualization 32
EI Performance Monitoring with AppDynamics • Configuring App Agent and WSO2 Enterprise Integrator Edit the integrator.sh in the EI-Installation/bin by inserting the line- -javaagent:"/path-to-app-agent-directory/javaagent.jar" 33
