In addition to this, these tools help you maintain network services and offer detailed reporting of all the work that the employees are doing. Here, we will discuss our pick of the ten best open source monitoring software to use in 2023. In 2023, when most of the workforce is operating from their homes, both small and large scale companies need monitoring software to see the progress of assigned tasks to the employees. Companies like Google, Facebook, and Apple have asked their employees to continue their work from home even in 2023 as it helps them in cost reduction. Monitoring software made it possible for these companies to churn out the same productivity level from their employees from their homes as they were getting when they were in the office. As a result, it is necessary to have monitoring software in 2023 as it helps reduce time wastage, which is taken away by the constant work update meetings. Today, we are going to tell you ten of the best open-source monitoring software to manage your business. It doesn’t matter if you are a startup or an MNC; you surely need monitoring software to increase your employee’s productivity. The best thing is that all of these monitoring tools are open-source. Therefore, as a buyer, you don’t have to worry about paying a hefty price to use these tools.

    Why Do You Need a Monitoring Software?

    First and foremost, the most important thing is to give companies a benchmark to compare their productivity and find ways on how they can be much quicker in their development and deployment cycles. Other important reasons to go for monitoring software are:

    • It’s a great way to know about the health of your IT systems, but it doesn’t just end there. Just because it looks like it's working doesn’t mean it is working at this optimal speed. With the help of monitoring tools, you get to know about your company's ins and outs.
    • Monitoring tools not only provide you with the assistance of finding issues, but they also fix the problem all by themselves using machine learning and artificial intelligence. Thus, with monitoring tools, you get to reduce the manual work required in your company.
    • When you deploy this software in your company’s working environment, you get to find out about your IT department's productivity. You will find out which of your company's departments or teams need an upgrade and which ones are working at their best. Thus, you get to manage your IT budget more competitively.
    • Lastly, you get to see things in plain black and white, so you don't have to think twice or have to come up with a justification to prove a point while making a decision.

    10 Best Open Source Monitoring Software

    1. Prometheus

    prometheus Starting our list of the best open source monitoring software, the first one is Prometheus. This monitoring software has its Prom Query language. It is easy to learn, and once the initial learning is done, one can create their own set of alerting rules. In addition to this, Prometheus comes with several functions that can be used to filter and provide mathematical calculations, which can be sent via alerts. There is one thing that is quite concerning, and that is, to create rules, you first need to know all the metrics names. Also, the client library isn’t stable, and you need to make a few tweaks to make it run on your systems.

    Features of Prometheus

    • It has inbuilt alerting metrics that can be used with virtual machines and has Kubernetes clusters.
    • There are several already developed free-to-download Prometheus metrics present in the public repository.
    • The working is based on the pull model, and it helps users to decide at what rate they want to pull the data from the client-side.

Thus, it might be hard for newcomers to get used to its work. There are some drawbacks to using Nagios too. The first one, which is quite evident, is the dated interface. This makes it a challenging job for new developers to understand and implement the monitoring software.

Also, there is only one version of the software, so you don’t have to worry about finding the latest software in the line-up or downloading and installing new patches every month. Yes, there is a graphical user interface, but it is elementary, so you need to know how to configure and use this software.

It might not be easy to determine if some local software agent gives the plug-in or the community has provided it. On the other hand, sometimes, you get to face pop-up ads during your usage, which could easily hinder the application's user experience.

Likewise, you get the freedom to integrate the existing monitoring system with this one without having to add any plug-ins. There is one addition which we would like to make to this almost-perfect open source monitoring software. The software needs to have a customizable menu of the web GUI.

    8. Graphite

    graphite Graphite is a monitoring software solution that is developed in Python. It is one of the few monitoring software that supports dashboard editing as it uses the Django web app. Likewise, users mostly rely on Grafana for the user interface as the built-in UI didn’t age well. You are not going to get plug-ins that were explicitly created for Graphite, but the compatibility is available. Everything is fine with this software, but one place where it lacks is the inconsistency in acquiring the data. Sometimes it takes more than the required time to fetch the data from different systems.
