10 Best Linux Monitoring Tools in 2024
Linux was created in 1991 by Finnish coder Linus Torvalds with the intention to build a new free OS kernel. Little did he know, thanks to its huge community, Linux grew into a giant, comprising millions of lines of code across multiple distributions, each crafted for a specific use.
Among the most popular Distros, especially for servers belong:
- Ubuntu
- Debian
- Fedora
- Red Hat Enterprise Linux
- OpenSUSE
- SUSE Linux
Usually, most of the “flavors” branch out from a single origin distribution. If you want to learn more about the timeline and Linux “family tree”, check out this infographic.
Linux Monitoring Benefits
Unix-based operating systems are often a go-to platform for most developers on both on-premise and cloud infrastructures. It’s thanks to its significant customizability, low-resource requirements, reliability, security, and also continuous development by its community. All this comes for a price and often, poorly configured Linux machines are often left paralyzed by their own design. Packages coming from multiple contributors collide, cron jobs fail or you encounter hardware-related issues such as memory or storage capacity. Monitoring can help you prevent it, or at least, spot any issues soon enough.
The Best Linux Monitoring Tools and Software in 2023
We’ve established that you should always monitor your Linux machines. There are a lot of solutions allowing for full observability ranging from open-source and freemium all the way to enterprise-ready solutions. Let’s take a look at some of the best available.
1. Better Stack
Better Stack is a complete log management solution from Better Stack, allowing you to collect, transport, analyze, monitor, store, and archive logs from all over your cloud architecture.
By offering integrations into stacks like Kubernetes, Heroku, Logstash, Rails, Docker, or AWS, and more, you get a broad array of options for monitoring. Thanks to custom-built technology and data stored in ClickHouse, you can work with your logs more efficiently and save funds. All the collected data are sent to Grafana for comprehensive visualization and more efficient intel management.
Better Stack allows you to query your logs the same way you'd query your database with SQL-compatible structured log management. Better Stack allows you to search & filter petabytes of logs in a moment and set an anomaly detection alert to receive alerts when your logs become out of the ordinary.
One of the greatest benefits of Better Stack is built-in collaboration features, where you can cooperate with your colleagues in a google docs-like environment, save, share, and archive parts of code, and collaborate with your colleagues.
Tighter security is one of the main benefits of log monitoring, and Better Stack itself is one of the most secure tools available. Using industry-standard best practices and cooperating only with data centers compliant with DIN ISO/IEC27001 certifications, your data is safe during both transit and storage.
Main Benefits of Better Stack:
- Inexpensive and extremely efficient ClickHouse based storage
- Integration with Better Stack Uptime, enabling even better observability and incident management
- Pricing starts at $0.25/GB

3. Datadog
Datadog offers more than 450 key integrations, including AWS, Docker, or Azure what proves it to be a really versatile partner when it comes to server monitoring.
You can get Datadog for free. Their premium bundles start at around $18/month, and you get unlimited alerts, custom metrics, outlier detection, and 15 months of data retention. Following Enterprise bundle for $23/ month offers machine learning-based alerts and premium support.
Main Benefits of Datadog:
- Anomaly Detection
- Forecast Monitoring
- IoT Device Monitoring
4. New Relic
You can get New Relic for free and access the basic logs management and analyzing features. The rest of the packages are priced depending on your usage, where you pay for everything you use on top of the free plan.
Main Benefits of New Relic:
- Kubernetes monitoring Pixie
- Multiple by use case solutions
5. Dynatrace
Thanks to advanced observability across PaaS and container technologies like AWS, Azure, Kubernetes, or Cloud Foundry, you gain access to process detection and resource utilization, network usage, and performance, log monitoring. Or you can use it to hold your partners accountable and verify their SLAs by third-party data and event monitoring integration. However, bear in mind that Dynatrace's complexity comes with a price, and fully plunging into how it works takes time.
Dynatrace's pricing depends on the monitoring solution. Their Full-stack monitoring starts at $69/month for 8 GB per host. Infrastructure monitoring offering observability for cloud, containers, and data center technologies, including AlOps, starts at $21/month.

Checkmk uses auto-discovery to help you pick the most relevant metrics for you and your project. You can monitor your infrastructure using powerful agent-based monitoring, but also agentless monitoring via HTTP/SNMP, or via a direct API connection.
Checkmk does not offer preset subscription models. You can calculate your own solution on their pricing page. Price will depend on the Edition you chose, the number of services you want to add on. The Default setting starts at $600/month without tax.
Main Benefits of checkmk:
- Log and event monitoring
- Infrastructure monitoring

Main Benefits of Zabbix:
- International, complex service covering a lot of solutions
- Open-source (but paid training is needed in most cases)
- User-friendly
9. Prometheus
Prometheus enables you to collect and store metrics as time-series data, meaning that data is stored with a respective timestamp and optional key-value pairs called labels.
Prometheus uses its own PromQL query language, collects time series via a pull model over HTTP, pushes data over an intermediary gateway. It allows for multiple different approaches to data visualization. Prometheus is usually deployed alongside Grafana since it supports out-of-the-box support.
However, bear in mind that Prometheus delivers reliable service, but if you have a zero fault tolerance policy when it comes to data accuracy such as per-request billing, Prometheus might not be the right choice.
Main Benefits of Prometheus:
- Open-source platform developed by a plethora of community contributors
- CNCF project
- Grafana integration
10. LogicMonitor
It supports more than 2000 integrations, modules, and pre-built templates for on-premises and cloud infrastructures. LogicMonitor is truly user-friendly since it offers query options for all experience levels. It also allows you to access raw data up to 12 months old. Metrics, logs, and log anomalies are all associated with their corresponding devices, cloud instances, and containers.
LogicMonitor manipulates your data with machine learning tools, which decreases troubleshooting times and allows better workflow by sparing your engineers of unproductive tasks. Anomalies are automatically detected and contextualized for easier root cause analysis. LogicMonitor offers Full IT operations lifecycle support via integrations like ServiceNow, CMDB, and Ansible.
One of the biggest disadvantages is the need to communicate your subscription with a sales team. You need to get a custom quote.
Main Benefits of LogicMonitor:
- Heavy usage of automation and machine learning methods
- Suitable of all experience levels without compromising functions
