Welcome to SigNal 07!

We sipped coffee, shipped code, fixed bugs, and made commits! The highlight of November was the alerts feature release 🔔. We also expanded our team and got our first community-led tutorial on how to monitor Ruby on Rails app with SigNoz.

Let's dive in to see what humans of SigNoz have been up to in the month of November.

What we shipped?

We made four releases last month, with the capability to set alerts in SigNoz as a major feature upgrade.

Latest Release:
Release v0.5.1

Alerts setting and management is a key feature of any APM tool. Let's see how we have enabled this in SigNoz.

Setting alerts in SigNoz

You can now set alerts for metrics that matter to you with SigNoz! 🎉

We have kept the UI for setting alerts very simple. You can use simple expressions to get started. You can use labels, summaries, and descriptions to provide better context to your alerts. Let's get a sneak peek. If you have set up alerts in Prometheus, this should look very familiar.

The alerts page on the SigNoz dashboard has two tabs:

  1. Alert Rules
    For setting expressions you want to evaluate to start firing alerts.

  2. Triggered Alerts
    Shows the alerts which are in firing and pending state.

Creating rules for alerts involve three simple steps:

  • Set the expression you want to evaluate to true to trigger alerts
  • Set the period for which you want to wait (after the expression is true) to start firing alerts
  • Set labels like severity to communicate how severe the issue is if this alert starts firing
Setting alerts is easy with expressions.

In the current release, we support slack as a notification channel. We will be enabling more channels with upcoming releases.

Here's a quick video on how to set alerts and receive notifications on Slack channels:

We would love to hear your feedback on alerts. Join our slack community to pass on any suggestions for improvement.

Package SigNoz as a Single binary
Currently, installing SigNoz requires having/installing docker. But this might be an overhead for someone just testing out SigNoz. So we intend to provide a single binary application to reduce this friction.

We have also noticed trying to install the docker script as one of the reasons for users dropping out. Let us know what you think; we would love to hear suggestions on how to make trying out SigNoz easier. Comment on this issue, or use our GitHub discussions.

What's upcoming?

Helm charts for ClickHouse Setup

Our team will work on enabling the deployment of SigNoz with ClickHouse setup using helm charts. Helm charts are the preferred way of deploying applications on Kubernetes and our users have requested this feature.

Expanding the team

We are excited to inform you that we have expanded our team with Vishal Sharma joining as a backend engineer. He is passionate about deep tech and has great plans on how to make SigNoz better and he has already made his first PR!

To unwind, Vishal loves to play chess and listen to podcasts for personal growth.

Community-led tutorial

Leunardus Vederis, a Ruby on rails developer wrote a tutorial on how to monitor Ruby on Rails app with SigNoz and OpenTelemetry. This was a first for us that made us all happy! 🥳

We are building a developer-first APM tool, and we envision a future where the community actively participates in educating others about open-source benefits.

Contributor Highlight

We want to thank these amazing contributors who made SigNoz better with their contributions. 🤗

From our blog

FastAPI is a modern Python web framework based on standard Python type hints that makes it easy to build APIs. It is based on ASGI specification, unlike other Python frameworks like Flask, which is based on WSGI specification.

OpenTelemetry is a great choice to instrument ASGI frameworks. As it is open-source and vendor-agnostic, the data can be sent to any backend of your choice. In this blog, learn how to monitor your FastAPI applications with OpenTelemetry and SigNoz.
