Graphite enables creation of informative dashboards full of metric aggregations, these dashboards can be used for visual anomaly detection and future trends prediction. While Graphite is great at storing metrics, LogStash and ElasticSearch allow to collate and filter monitored log files and events in a central place so that there is no need to search for them at the individual locations where they are created.
Using ElasticSearch allows to search for a needle in a haystack when required, but also see trends of events as these aggregate over time. Metrics stored in graphite and events stored in ElasticSearch can be arranged in beautiful and informative dashboards using Kibana , Grafana or Tessera. Highlight key metrics of importance to be easily identified at a glance by an operator, providing meaningful insight into the state of applications and infrastructure.
Display of trends and anomalies can help prevent and fix exceptions before these become a massive problem. It is designed to handle millions of even per second with low latency. It is an apt monitoring tool for highly distributed scalable systems. Sensu is indorsed as a full-stack monitoring tool.

AppNeta PathTest is a free network volume testing tool intended to aid businesses to comprehend the true ability of their network. Kibana is an extremely versatile analysis tool supporting various different ways of slicing and dicing data.
ELK comes with its own set of challenges, of course, especially at scale. You can understand the key differences between these options here. Pros : Huge community, easy to deploy and use, rich analysis capabilities. As articulated in the intro to this list, open source is both a key driver and an enabler of modern development methodologies and DevOps specifically that require speed, flexibility and extensibility.
As great as open source tools are, they are not without challenges. To paraphrase Tolkien, not all that is open source is actually free. Yes, the monitoring tools listed above will not require a credit card or a purchase order. But at scale, and when deployed in production, they will most likely cost your organization in terms of the time and resources required to deploy and maintain over time. This is something to consider when planning your telemetry system. IT environments are only getting more complex and you need to think carefully before adding another layer of complexity to your day-to-day work.
I hope to be slowly adding more and more open source monitoring tools to this list, and like I said — feel free to comment below to suggest which tools these should be. Platform Overview.

Most stakeholders are always searching for economic value in every digital infrastructure investment they make. Sensu Go is an observability pipeline platform that supports server performance metrics and allows you to address gaps in monitoring visibility of correlations between metrics, logging, and tracing.
Existing monitoring technologies such as Nagios, StatsD, Telegraf, Prometheus, and others can be integrated into Sensu seamlessly. One of the key features of Sensu Go is its ability to support monitoring as code. It lets you define monitoring workflows using declarative configuration files shared with team members, as well as write tests, perform version control, edit, and review in a proper GitOps manner.
Supporting multiple clouds and all their related infrastructure, Sensu is one of the best server monitoring solutions if your organization observes GitOps principles and treats everything as code. Sensu Go is entirely free up to nodes; following that, there are subscriptions to various node bundles. Nagios XI is a comprehensive software for monitoring enterprise servers and networks. The business version of Nagios, Nagios XI was created on top of the open-source version and has more functionality and requires less administration time.
Nagios focuses primarily on server metrics, application performance, and network traffic. It collects data via the use of agents placed on both the network elements and the components it monitors. Nagios is available as a downloadable bundle with specific packages for each product running on Windows or Linux. Once the agents have been deployed, data should begin coming into Nagios and its standard dashboards. The solution is highly customizable and can scale out of the box, making it a perfect fit for many enterprises.
This high customizability does, however, come with additional complexity and maintenance overhead. Nagios XI is free for small environments, but after seven monitoring nodes, you need an annual license for support and Nagios server maintenance. There are plenty of server performance monitoring tools available on the market—both open-source and SaaS models.
At the end of the day, they all get the job done. Below are a few key areas to keep in mind when choosing an enterprise monitoring solution. This is a no-brainer. Your monitoring solution needs to be able to collect and analyze all the metrics that are important to you.
You also have to be able to configure the metrics you do need and customize them to match your requirements. For an enterprise monitoring solution, you need to look for a solution that is easy to set up, requires less maintenance, and has most of your needs covered via its default settings for alerts and dashboards. Even if a tool supports all the metrics you need, it is cumbersome if there is no correlation between them, especially when debugging a problem.
Having proper correlation between metrics can save you a lot of time and help you drill down to the root cause of your problem within minutes.
Sometimes, it is not really feasible to give a static threshold for a given metric to fire an alert. Sometimes, you might not even know an alert is needed until something goes wrong. Tools with anomaly detection capabilities, integrated with machine learning and artificial intelligence, will automate and configure most alerts for you. Enterprises often have teams dedicated to observability. User access management and fine-tuned access control are required to run a tight ship.
SaaS solutions for monitoring have become widely popular today, as managing and maintaining enterprise-level monitoring platforms by yourself on-premises can be very costly and time-consuming—not to mention the complexities of DIY monitoring to make sure your platform is running as expected.
It is best to offload your monitoring to a SaaS and take the complexity and operational overhead away. Real-time server monitoring is required to keep your applications running smoothly.
