Nagios vs Sentry: What are the differences?

Developers describe Nagios as "Complete monitoring and alerting for servers, switches, applications, and services". Nagios is a host/service/network monitoring program written in C and released under the GNU General Public License. On the other hand, Sentry is detailed as "Cut time to resolution for app errors from five hours to five minutes". Sentry is an open-source platform for workflow productivity, aggregating errors from across the stack in real time. 500K developers use Sentry to get the code-level context they need to resolve issues at every stage of the app lifecycle.

Nagios belongs to "Monitoring Tools" category of the tech stack, while Sentry can be primarily classified under "Exception Monitoring".

Some of the features offered by Nagios are:

  • Monitor your entire IT infrastructure
  • Spot problems before they occur
  • Know immediately when problems arise

On the other hand, Sentry provides the following key features:

  • Real-Time Updates: For the first time, developers can fix code-level issues anywhere in the stack well before users even encounter an error.
  • Complete Context: Spend more time where it matters, rather than investing in low-impact issues.
  • Integrate Everywhere: Drop-in integration for every major platform, framework, and language -- JavaScript, Python, PHP, Ruby, Node, Java, .NET, mobile.

"It just works" is the primary reason why developers consider Nagios over the competitors, whereas "Consolidates similar errors and makes resolution easy" was stated as the key factor in picking Sentry.

Nagios and Sentry are both open source tools. It seems that Sentry with 21.4K GitHub stars and 2.45K forks on GitHub has more adoption than Nagios with 60 GitHub stars and 36 GitHub forks.

Airbnb, Uber Technologies, and Instagram are some of the popular companies that use Sentry, whereas Nagios is used by Uber Technologies, Dropbox, and 9GAG. Sentry has a broader approval, being mentioned in 1341 company stacks & 434 developers stacks; compared to Nagios, which is listed in 177 company stacks and 40 developer stacks.

    For my portfolio websites and my personal OpenSource projects I had started exclusively using React and JavaScript so I needed a way to track any errors that we're happening for my users that I didn't uncover during my personal UAT.

    I had narrowed it down to two tools LogRocket and Sentry (I also tried Bugsnag but it did not make the final two). Before I get into this I want to say that both of these tools are amazing and whichever you choose will suit your needs well.

    I firstly decided to go with LogRocket the fact that they had a recorded screen capture of what the user was doing when the bug happened was amazing... I could go back and rewatch what the user did to replicate that error, this was fantastic. It was also very easy to setup and get going. They had options for React and Redux.js so you can track all your Redux.js actions. I had a fairly large Redux.js store, this was ended up being a issue, it killed the processing power on my machine, Chrome ended up using 2-4gb of ram, so I quickly disabled the Redux.js option.

    After using LogRocket for a month or so I decided to switch to Sentry. I noticed that Sentry was openSorce and everyone was talking about Sentry so I thought I may as well give it a test drive. Setting it up was so easy, I had everything up and running within seconds. It also gives you the option to wrap an errorBoundry in React so get more specific errors. The simplicity of Sentry was a breath of fresh air, it allowed me find the bug that was shown to the user and fix that very simply. The UI for Sentry is beautiful and just really clean to look at, and their emails are also just perfect.

    I have decided to stick with Sentry for the long run, I tested pretty much all the JS error loggers and I find Sentry the best.

    Why we spent several years building an open source, large-scale metrics alerting system, M3, built for Prometheus:

    By late 2014, all services, infrastructure, and servers at Uber emitted metrics to a Graphite stack that stored them using the Whisper file format in a sharded Carbon cluster. We used Grafana for dashboarding and Nagios for alerting, issuing Graphite threshold checks via source-controlled scripts. While this worked for a while, expanding the Carbon cluster required a manual resharding process and, due to lack of replication, any single node’s disk failure caused permanent loss of its associated metrics. In short, this solution was not able to meet our needs as the company continued to grow.

    To ensure the scalability of Uber’s metrics backend, we decided to build out a system that provided fault tolerant metrics ingestion, storage, and querying as a managed platform...

    Sentry has been very useful for me and my team. I caught a bug in staging — just as one example — which I wouldn't have caught before deploying to production. That's the sort of thing that happens on a regular basis with Sentry.

    I didn't personally make the decision to use Sentry since I'm part of a very large organization that chose it before I joined company. But we've been more than happy enough with Sentry that we use it across most of our teams, regardless of their stack.

    Lots of companies I respect were using it + open-source + great features and UI. Went for the hosted version, since it plays nice with Heroku. I like how they group together similar errors, give you the ability to mute events or mark them as solved. P.S. check out the Founder Stories feature we did on Sentry if you want to know how they started, its an awesome story.

    We use Nagios to monitor our stack and alert us when problems arise. Nagios allows us to monitor every aspect of each of our servers such as running processes, CPU usage, disk usage, and more. This means that as soon as problems arise, we can detect them and call out an engineer to resolve the issues as soon as possible.

    The error and event tracking in Sentry is superb. Being able to assign the raw error to people along with all information at the time the event occurred means that we're tracking and fixing problems before they become apparent to customers. We use the self-hosted instance of Sentry.

    Sentry is a very powerful error reporting tool. We use it both on front-end and back-end of Ataccama One. It proved to be invaluable in providing insights on our errors - what caused it, what user did before the error occured, stack trace, release tracking and more.

    We use Sentry to gather our thrown non-checked exceptions in one place, so we don't have to crawl through all our logs manually. All standalone-applications, our website aswell as our game-servers are linked into sentry.

    Sentry is amazing, most of our systems send their exceptions to sentry. We couldn't live without it and get a much better understanding of how our code is behaving in the wild. Plus it integrates with Github.
