Log analysis at scale requires structured logging, and Logstash can transform unstructured logs to be sent for analysis. Logstash can collect and parse a wide variety of data types. The ELK stack is capable of ingesting log data of different types and from different platforms, thanks to Logstash. Some of the key features of the Elasticsearch stack include: Some common charts are area charts, pie charts, heat maps, etc. With data querying and analysis features, Kibana lets you analyze your log data for insights. Kibana acts as the frontend of the Elastic stack and enables you to create visualizations from the data stored in the Elasticsearch database. Finally, it can send the filtered data to multiple destinations. It can ingest data from multiple sources in both structured and unstructured formats and then parse it. Logstash is a log collector that helps you to collect, process, and transform log data. But it is more popularly known as a search and analytics engine because of its extensive features on search capabilities. All here’s what the three tools do:Įlasticsearch is a NoSQL document-oriented database. Together, they provide log management and analysis capabilities. The Elasticsearch stack or the ELK stack consists of three tools: Elasticsearch, Logstash, and Kibana. ![]() Prometheus Dashboard built using Grafana (Source: Prometheus website) Prometheus comes with a basic visualization layer, but it can be combined with Grafana to create rich visualizations. The alert manager also provides capabilities to group alerts in a single notification. Prometheus comes with an alert manager that lets you create alerts on metrics. It provides client libraries in various programming languages to do(Go, Python, Ruby, etc.). It pulls metrics from an application and exposes them in a format it understands on an HTTP endpoint. Prometheus uses a query language called “Prom QL” to query the metrics data collected.ĭata collection for Prometheus is pull-based. The multi-dimensional data model enables rich contextual metrics monitoring. You can also store an optional set of key-value pairs called labels for that metrics. It stores data as time series (data that is tracked at an increment in time). Some of the key features of Prometheus are: Prometheus is often combined with Grafana, an open-source data visualization tool to provide richer dashboards. Prometheus provides a visualization layer called the Expression browser. Examples could be error responses, service requests, response latency, CPU usage, memory usage, etc. Metrics are measurements taken from an application or IT infrastructure that change over time. Its primary focus is on gathering, storing, and querying metrics. It is suited to monitor metrics both from traditional IT infrastructure as well as dynamic container environments. It collects and stores metrics as time-series data (metrics that change over time). Prometheus is an open-source metrics monitoring tool. Let’s learn about both these tools in detail. Combined together, these three tools form a popular log management platform. The Elasticsearch stack consists of three tools: Elasticsearch, Logstash, and Kibana. These metrics can be aggregated to give insights into the behavior of your systems. Prometheus enables you to capture time-series data as metrics. ![]() Prometheus is a time-series metrics monitoring tool. ![]() In this article, we will see what Prometheus and ELK stack is and compare their differences. But while Prometheus is primarily meant to monitor metrics, the Elasticsearch stack or the ELK stack is mainly used to collect, store, analyze, and visualize application logs. Prometheus and the Elasticsearch stack are both used for monitoring applications. ![]()
