Unified monitoring to the rescue
So, what’s an ideal monitoring framework? A framework capable of capturing data, logs from any source, efficiently storing them, utilizing historical data to create machine learning models for predicting system issues and utilizing distributed tracing for Root Cause Analysis.
Elastic releases and components, such as Beats, Elasticsearch, Logstash and Kibana (BELK), part of an open source stack, have a huge pool of easily pluggable light-weight edge data shippers. These shippers are capable of collecting system and application-related metrics, reading log files and forwarding the time series data and metrics to data pipelines for further processing. The data pipelines are the ingestion workhorses that collect, parse, transform and store data. This solution also provides the ability to search and analyze large data volumes, apart from supporting extensive reporting features.
There are additional capabilities to enhance the power of the Elastic Stack.
In a highly distributed architecture, correlation of data across multiple layers is a challenge. With microservice implementations, the challenge multiplies. The answer to this problem lies in Distributed Tracing. Distributed tracing frameworks, like Zipkin, provide uniform and consistent tracing capabilities and are a force to be reckoned with.
Discovering a problem is the first step in resolving it. Eliminating the delay between when the problem occurs and the time the problem is detected, immediately brings one closer to identifying the root cause. Predictive Monitoring using anomaly detection comes in handy here.
Anomaly detection with an open framework such as Apache Spark, helps predictive monitoring in finding outliers in an otherwise ordinary set of data. Machine Learning algorithm such as Support Vector Machine, Bayesian Networks and k-means clustering are widely used in anomaly detection. Based on the use case and data attributes, either supervised unsupervised learning techniques can learn from historical data and easily detect outliers in the present data. Anomaly detection can be used for cases such as network security analysis, fraud detection and error detection.
A predictive monitoring solution built on top of open source frameworks, such as BELK, OpenTracing and Apache Spark, leverages the flexibility of Beats and Logstash, the power of an OpenTracing framework like Zipkin, along with the intelligence of the Spark ecosystem. It provides a cost-effective yet flexible monitoring platform that can be used for better decision making. It can also be applied across a variety of business use cases.
