2. The Elastic Stack

The Elastic Stack (ELK Stack) monitoring solution combines the capabilities of three open-source projects: Elasticsearch, Logstash, and Kibana. Elasticsearch is responsible for search and analytics, while Logstash helps inject and transform data from different sources before sending it to Elasticsearch. Kibana enables visualization through charts and graphs based on data analyzed by Elasticsearch. These capabilities can be used for metrics collected from multiple sources in your infrastructure and for delivering insights into your environment’s health. The integration for infrastructure monitoring is enabled through the Metricbeat module, which correlates metrics from various sources, such as servers, Docker containers, Kubernetes, and many more. The module creates index patterns in Kibana that help with visualization of infrastructure status. You can also set up alerts for index/metrics-based thresholds and send notifications through email, Microsoft Teams, Slack, or other third-party integrations.

Pros

Ability to host ELK on-premises or use a hosted solution

Ability to view CPU/memory utilization and process-level statistics in Kibana dashboard

Real-time customization, analysis, and visualization of data to deliver in-depth insights

Analyzes telemetry data from distributed infrastructures in real time

Libraries for multiple scripting and programming languages

Cons

Complex and multi-step deployment

Complex infrastructure configuration needed to ensure resiliency, high availability, and data usability

Pricing

ELK is open source and free to download and use. However, you do have to pay for maintaining the infrastructure (i.e., compute), storage, and network bandwidth required to operate the ELK components, which can be expensive.

3. Prometheus

Created by former Google employees, Prometheus is a popular open-source infrastructure monitoring tool, originally intended to monitor heavily containerized environments. It works on time-series-based data. The services it monitors should expose an HTTP metrics endpoint that is periodically polled by Prometheus. Various metrics and the current value of those metrics should be accessible over this endpoint. In certain cases, you can’t change the containerized service to send the metrics required for Prometheus. When that happens, the Prometheus exporter can be bundled with the container service as a sidecar pod container to collect the metrics. Prometheus uses a single node-based configuration and does not require distributed storage in the architecture. It also uses Prometheus Query Language (PromQL) for querying and aggregating monitoring data in real time. The Alertmanager generates and sends out alerts based on configured alerting rules.

Pros

Uses numeric time-series data, which is ideal for dynamic, service-oriented, and microservices-based architectures

Standalone service with no dependency on external network or storage

Doesn’t need extensive infrastructure to operate

Well integrated for Kubernetes infrastructure monitoring

Grafana integration for visualization

Cons

No native long-term storage or automated scaling, which may be required in large enterprise environments Needs integration with external dashboards, like Grafana, for visualization (involves additional configuration overhead)

Pricing

Prometheus is completely open source and can be downloaded for free as Docker images or precompiled binaries. All components are licensed under Apache License Version 2.0 and are available on GitHub.

4. Zabbix

Zabbix is one of the most popular open-source infrastructure monitoring tools on the market. It’s a versatile solution that offers multiple monitoring options: network, server, cloud, application, and databases, to name a few. Zabbix provides extensive visualization capabilities that give you insight into infrastructure health. You can leverage the tool’s notification and remediation capabilities to identify and address issues in real time. Zabbix supports multiple platforms (Windows, Linux, Unix, etc.) and gathers important metrics like CPU, memory, and network usage.

What Is the Best IT Monitoring Tool for You?

Your infrastructure monitoring tool must provide a bird’s-eye view of your IT environment’s health status, including performance, availability bandwidth, utilization, and security. It should be able to generate infrastructure alerts based on the monitored metrics and create reports that deliver insights, irrespective of how or where the application is hosted. Some solutions are specialized for specific aspects of this (e.g., performance metrics), while others provide full-spectrum monitoring with options for customization. In any case, when choosing an IT monitoring software, the complexity of set up is a deciding factor. Some tools come with out-of-the box integration with your infrastructure components, while others require more effort to configure. You may be tempted to develop your own monitoring tools to avoid vendor lock-in and get more flexibility. However, in the long run, this will add to the complexity of maintaining your code base and will require additional effort each time you want to add new features. When it comes to build vs. buy, it’s always best to consider the relevant monitoring metrics and then buy an established monitoring tool to avoid additional complexities. If you want an inkling of what such a tool can do for you, check out Sematext Monitoring, our infrastructure monitoring tool that provides full-stack visibility for your IT environment. There’s a 14-day free trial available for you to try all its functionalities.
