About Sensu

Sensu is a cloud-based network monitoring solution that assists businesses of all sizes with performance data collection and diagnostics. Its key features include server performance, bandwidth monitoring, uptime monitoring, network resource management and event logs.

The application comes with a module that enables network teams to monitor ephemeral container infrastructures such as Kubernetes, RedHat OpenShift, Docker, Mesos, Cloud Foundry and collect events, metrics and labels. Teams can use this system to collect StatsD and Prometheus metrics and store data with tools including InfluxDB, ElasticSearch or Splunk. Network managers can use this solution to monitor large-scale environments by traversing complex network topologies such as NATs, VPNs and firewal...

Awesome monitoring framework with unlimited integration possibilities

Sensu Go is a powerful framework to build an event pipeline tailored to the needs of their users. Events can be gathered via various different ways and processed highly accurate via handlers. Sensu Go has its strength in dynamic environments and when it is interconnected with other tools of the IT environment used by administrators and managers.

Pros

The monitoring framework following the microservice approach gives users the ability to fully embed Sensu Go into their environment and workflows. The strengths of Sensu Go consist in giving users endless possibilities to process events using the event pipeline with filters and mutators. Handlers represent the integration to 3rd party tools, which could be everything you can think of. Every event is processed as a json object, what makes it very easy to build interfaces between Sensu Go and $product - you name it. On the other hand the agent is able to gather information in different ways. It supports several plugin output formats, what gives the possibility to choose from a pool of thousands plugins, scraping Prometheus Exporters, or just using in-house developments. Furthermore it supports to accept events/metrics via Agent API or the built-in StatsD listener. The documentation is awesome and complete. Since it is API-driven, users are able to fully automate Sensu Go using configuration management tools like Ansible, Chef, Puppet or Salt. The slack community is big and you can get help quickly.

Cons

Coming from classic montioring tools it takes some time to understand how Sensu Go works, but it's definitely worth it. At the moment Sensu Go brings some in-built filters (and simple filter examples in the docs) and some maintained handlers. If users want to go beyond that they need to look for community-implementations or write own filter expressions and handlers, what assumes that they are able to script or understand javascript (for filter expressions), golang or any other programming language (for handlers). What sounds like a con in one way is a pro in another, because it gives the user endless possibilities.

A powerful monitoring event pipeline

Pros

Sensu provides an extremely flexible monitoring event pipeline for users of all sizes. Sensu is available as an open source, MIT licensed product allowing even the smallest organizations to leverage Sensu to provide a robust and flexible monitoring pipeline for all of their environments. Additionally, Sensu provides enterprise features (LDAP, AD, native external integrations) along with an incredible support team for their enterprise version. Sensu provides native primitives that allow users to significantly reduce alert fatigue via filters, dependencies, aggregations, and scheduled silences. These primitives increase the value of Sensu monitoring event pipelines allowing "robots" to do the initial alert remediation and only notifying a human when there's real issues.

Cons

Sensu Core and Sensu Go both provide dashboards. In my experience, the larger the Sensu installation, the harder the provided dashboards become to use. However, Sensu Go now has native RBAC controls and appears to be significantly improving the dashboard with each release.

Big improvement over Nagios, but still room for growth

After maintaining a Nagios XI installation for a few years, I decided to switch to Sensu because I can tell that Nagios is a creaking giant that doesn't meet the needs of the modern world especially well without a *lot* of elbow grease. Sensu's backend and deployment is considerably easier than Nagios, but the GUI and documentation still need a lot of work. Some of Sensu's best features, like assets, tarballs that package up programming language runtimes for easy deployment, aren't easy for smaller teams like mine to implement because the documentation talks about them as if you already know how to implement them. I've already been in touch with our Sensu account manager, and to their credit, they arranged for a meeting with one of their higher-ups to discuss our concerns. I think Sensu still has room for improvement before it's a truly good fit for a small business environment like mine, but it's still a solid improvement in some ways over what I was using with Nagios XI.

Pros

Sensu Go, the new version, is easy to deploy, and it's considerably easier to manage and scale as compared to Nagios, which we had been using.

Cons

The GUI interface still needs a lot of work; it's quite spartan compared to Nagios XI. The documentation isn't especially beginner-friendly; it lacks "hello world" examples and seems to assume that you're already intimately familiar with some of the concepts.

Sensu - the best open source monitoring tool

Pros

- Amazingly smooth way of deploying this. - No budget required. ;) - Easy to understand. - Solves most of your problems. - Have loads of plugins available.

Cons

- Cannot use a graph of the metrics throughout the day, or over a week in the dashboard. - The updates are not backward compatible.

Response from Sensu

Replied September 2020

Thanks for the great review, Debodirno! We're happy to hear you enjoy using Sensu. If you're referring to the responsive agents or the entity classes tiles on the dashboard, those displays are meant to be the current snapshot of the health of your environment. If you would like to discuss this in more detail, feel free to post your questions on Discourse [https://discourse.sensu.io/]

Best monitoring Framework, not the best monitoring product

I have used sensu for 4+ years and have become a maintainer in the last couple years. I really love seeing the diverse use cases that sensu helps organizations accomplish with core features as well as the community maintained plugins. Sensu has a really great community where I have had the benefit of leveraging many community contributions but been able to give back to such an awesome community. If you ever want to get involved with `core`, `sensu-plugins`, or the various CM (config management) projects reach out to me on the community https://slack.sensu.io

Pros

While many monitoring solutions try to be an out of box solution that is easy to get going and perform a prescriptive path Sensu took a step back and said instead of building a product we should build a framework. By taking the stance of framework first and product second what you get is a truly great experience where things work with little to no effort to get it spun up and going you can do so much more with it than the developers ever imagined people would use it. If you are willing to write code you can do pretty much anything you want by leveraging their framework and event pipeline. This can include writing new checks, metric gathering scripts, TSDB shippers, automated triage, automated remediation, etc.

Cons

Losing a lot of flexibility with filters in the transition from `sensu-ruby` to `sensu-go` but for most use cases you probably won't notice.
