OpenTelemetry vs. Prometheus - Difference in architecture, and metrics.

Whenever we detects something wrong with your site it can send you a notification. We have multiple channels available: Slack, Telegram, webhooks, and many more. The most popular channel our users use is just a simple mail. Behind the scenes, Oh Dear uses Postmark to send out mails. Postmark will inform us whenever a notification mail results in a hard bounce. A hard bounce means that the mail won't be delivered. The most common reason for this is that the mailbox doesn't exist (anymore).

Collectd is a data collection software that allows you to fetch metrics from a machine being monitored locally and push them to Graphite. Everything is done by plugins. The collectd plugins can collect metrics on CPU, memory, Postgres, JVM, and many more metrics. Plugins can also be used to push these metrics to Graphite, aggregate data, send alerts, and send notifications to email.

The growing popularity of IoT devices has revolutionized the way we interact with technology. From smart homes to industrial automation, these devices have become an integral part of our lives. However, managing and monitoring a large fleet of IoT devices can be a daunting task. With the sheer volume of data being generated by these devices, it becomes crucial to have a robust monitoring system in place.

In the observability space, it seems like everyone is talking about how to reduce costs and control the explosion of Prometheus metrics. It’s no wonder — our recent analysis of user environments suggests 20% to 50% of metrics generated are never used, but users are still stuck paying for them.

In this article, we will take a look at what Graphite and Grafana are and what they are used for. Some people might mix these two up, but they do completely different jobs when creating a monitoring system. Let’s take a look these tools in more depth.
