Prometheus

DevOps monitoring refers to the continuous, automated process of identifying, tracking, analyzing, and reporting on specific components of the entire pipeline.Monitoring DevOps increases development efficiency by allowing teams to find potential issues before or after releasing code to production.

Prometheus is an open-source systems monitoring and alerting toolkit originally built at SoundCloud.It is now a standalone open source project and maintained independently of any company. To emphasize this, and to clarify the project’s governance structure, Prometheus joined the Cloud Native Computing Foundation.Prometheus works well for recording any purely numeric time series.In a world of microservices, its support for multi-dimensional data collection and querying is a particular strength.It works on pull system architecture while Cloud watch and Newrelic works on push system architecture so sometime it became the resource overlaoded.

Grafana is a popular open source, general purpose dashboard and visualization tool that offers beautiful visualizations, interactive graphs and easy-to-set-up dashboards. It integrates with a diverse set of data sources, like Prometheus, InfluxDB, MySQL, Elasticsearch and Splunk.Some main features are Clean Data Visualization, Grafana Cloud, Plugins and Dashboard Customization.

New Relic is a full-stack monitoring tool that gives you visibility into the performance of your infrastructure components with rich dashboard capabilities. Rather than needing to switch context between different applications, New Relic allows you to monitor information from logs, infrastructure, applications, serverless functions, and more — all from a single tool. You can leverage New Relic to get real-time health information on key host metrics like CPU, memory, disks, and network status.New Relic’s insights feature ensures that you can easily track and query infrastructure monitoring data.

New Relic offers a free tier and additional paid tiers: Standard, Pro, and Enterprise. The paid tiers are based on data ingested per month, number of users, and number of incidents per month.

Nagios is one of the oldest infrastructure monitoring tools available both as an open-source tool (Nagios Core) and a paid enterprise solution (Nagios XI).You can use Nagios for centralized monitoring of applications, system metrics, operating systems, and other infrastructure components. Its extensive reporting capabilities, such as availability reports and historical reports that can be extended using third-party addons, is another highlight. Nagios offers a multi-tenant architecture with a user-specific view configuration, helps you detect outages quickly, and alerts you via e-mail or SMS when something goes wrong.Some features not available in the free open-source version.

Netdata’s distributed, real-time monitoring Agent collects thousands of metrics from systems, hardware, containers, and applications with zero configuration. It runs permanently on all your physical/virtual servers, containers, cloud deployments, and edge/IoT devices, and is perfectly safe to install on your systems mid-incident without any preparation.

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. You can use its out-of-the-box templates for the automated discovery of components to be monitored, with the flexibility to develop custom templates if required. You can set up Zabbix to generate alerts based on defined triggers and deliver them through e-mail, SMS, script alerts, webhooks, and more.

Conclusion:

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.They are multiple monitoring tools available in the market right now and each of them comes up with their own benefits and pricing. It is up to the developer to choose a tools which works best for their desired tasks.
