In 2024, monitoring is essential to modern DevOps teams' work. DevOps teams need reliable and flexible tools to effectively monitor and manage complex systems that can provide real-time insights into system performance, availability, and security.

Open-source monitoring tools have become increasingly popular due to their cost-effectiveness, flexibility, and community support.

## Pros and Cons of OSS Monitoring Tools for DevOps

Here are some advantages and disadvantages of open-source monitoring & observability tools compared to SaaS/hosted tools.

#### Pros

- **Customization**: Open-source monitoring tools allow for greater customization and flexibility in terms of monitoring configurations and integration with other tools.
- **Cost-effective**: Open source tools are often free or low-cost, making them a cost-effective solution for organizations with limited budgets.
- **Transparency**: The code behind open-source monitoring tools is open for scrutiny and can be audited, providing greater transparency and accountability.
- **Community support**: Open-source monitoring tools are often supported by a large community of developers who provide support and contribute to the development of the tool.

#### Cons

- **Complexity**: Open source tools often require more technical expertise and effort to install, configure, and maintain than SaaS monitoring tools.
- **Support**: While community support is available, it may not always be sufficient for organizations with complex or specialized monitoring requirements.
- **Security**: Open source tools may be vulnerable to security breaches, as they may lack the robust security features and updates provided by SaaS tools.
- **Scalability**: Open-source monitoring tools may not be as scalable as SaaS tools, as they may require additional hardware and infrastructure to scale effectively.

## Zabbix

Zabbix uses a client-server architecture, where the Zabbix server collects data from multiple agents installed on network devices, servers, and applications. It can also collect data from other sources such as SNMP traps, JMX counters, and IPMI-enabled devices.

Zabbix supports a wide range of data collection methods, including simple checks like ping, HTTP, and SMTP checks, as well as more advanced checks like SNMP, JMX, and IPMI checks. It also supports custom checks, which can be used to monitor the performance of custom applications and services.

## Healthchecks.io

Healthchecks.io is a service for monitoring cron jobs and similar periodic processes.

- Healthchecks.io **listens for HTTP requests ("pings")** from your cron jobs and scheduled tasks.
- It **keeps silent** as long as pings arrive on time.
- It **raises an alert** when a ping does not arrive on time.

Healthchecks.io is _not_ the right tool for:

- monitoring website uptime by probing it with HTTP requests
- collecting application performance metrics
- log aggregation

![Healthchecks.io](https://www.statuspal.io/images/blog/best-open-source-monitoring-tools-for-devops/healthchecks.png)

#### Top Features

- Open source, can be self-hosted
- Simple, clean dashboard
- Team & API access

#### Pros

- The interface is extremely simple to set up, with clear instructions for implementation.
- Within 5 minutes, you can have notifications when your server fails to report and when the server returns online.
- At the end of the month, you'll have an email report with your downtime.

#### Cons

- The service lacks advanced analytics and other advanced features.
- Those seeking such features may not find it to be a good fit. However, I believe that the simplicity of this service is a bonus. Adding more features could potentially detract from the excellent user experience.

## Sensu Go

Sensu Go is an **open-source monitoring** tool that allows you to monitor your infrastructure, including servers, containers, and cloud services. **Sensu has 3 key points: Simple, Scalable, and Multi-cloud monitoring.**

![Sensu Go](https://www.statuspal.io/images/blog/best-open-source-monitoring-tools-for-devops/sensu.png)

Sensu Go uses a **decentralized architecture**, where the monitoring checks are executed on client nodes **called agents**, and the results are sent to a backend server for processing and storage. This architecture allows for a more flexible and scalable monitoring setup, where you can add or remove agents as needed and distribute the monitoring workload across your infrastructure.

Sensu provides the Monitoring-as-Code functionality and automation that are essential for such dynamic environments ranging from completely automated deployment based on monitoring code templates (YAML configuration files), to flexible APIs to control all elements of the monitoring platform.

Sensu Go supports various types of monitoring checks, including **Nagios-style checks**, custom scripts, and plugins written in various languages. You can also use Sensu Go to monitor containerized environments such as **Kubernetes** and **Docker**, as well as cloud services such as **AWS and GCP.**

[Sensu Go Github repository →](https://github.com/sensu/sensu-go)

#### Pros

- Developers can code their own checks
- Easy configuration, scales well, and performance is good
- Message routing
- Nagios plugin compatibility
- Written in Go

#### Cons

- Not a very good UI
- Sensu Go has a learning curve, and it may take some time for users to become familiar with its functionality and configuration options.

## SigNoz

SigNotz is an open-source APM (application performance monitoring) tool that you can use as an alternative to other tools like Datadog and NewRelic. It can come in very handy to monitor your applications and troubleshoot problems.

Furthermore, SigNoz integrates OpenTelemetry, supporting various languages and frameworks that implement it, like Java, Ruby, Python, Elixir, and much more. It supports various modern technologies and frameworks such as **Kubernetes, Istio, Envoy, Kafka, gRPC**, and more.

![SigNoz](https://www.statuspal.io/images/blog/2022-12-28-devops-sre-tools-2023/signoz.png)

#### Top Features

- Monitor application metrics such as latency, requests per second, error rates.
- Monitor infrastructure metrics such as CPU utilization or memory usage.
- Track user requests across services.
- Set alerts on metrics.
- Find the root cause of the problem by going to the exact traces which are causing the problem.
