Monitoring stack for a fintech platform
Prometheus, Grafana, and alerting rollout that cut incident response time by 50%.
Set Up Grafana Alerts and Notifications via Slack, Email, or Webhook
I’ll admit it: I used to be the person who constantly refreshed my Grafana dashboards, nervously watching a CPU usage graph creep upwards. It was like babysitting a pot of water, waiting for it to boil. This, of course, is not a scalable strategy for managing a smart home system or any observability stack. The whole point of having these beautiful dashboards is to be proactive, not reactive. That’s where Grafana alerts come in.
Monitoring Disk Space Across Servers Using Node Exporter and Prometheus
Ever had that sinking feeling when your server runs out of disk space at 3 AM? I have—more times than I’d like to admit. After one too many midnight emergencies, I decided to automate disk space monitoring using Prometheus, Node Exporter, and Grafana. Here’s how you can set it up too, complete with alerts and pretty dashboards to keep your sanity intact. Why Monitor Disk Space? Disk space is one of those silent killers.
Prometheus Anomaly detection: Z-Score in PromQL
Monitoring HTTP request rates is one of the most basic yet essential tasks in observability. A sudden spike might indicate a traffic surge or even a DDoS attack, while a sudden drop could signal a backend failure. Static thresholds work, but they often miss subtle patterns or raise too many false alarms. A better way is to use statistical anomaly detection—specifically Z-score based alerts in Prometheus. In this post, we’ll walk through how to set up a Z-score PromQL alert to detect anomalies in HTTP request rates using only Prometheus and native PromQL.
Grafana 9 Alert : How to customize alert message
Grafana added the alert feature recently and it’s now released with the Grafana 9. That’s a great feature for the people who don’t want to set a proper alermanager and to configure it. I’ve took the time to explore the alert and play with it. Let’s see how it works! Deploy grafana and prometheus With the docker-compose file below run the grafana and prometheus docker-compose up -d. # docker-compose.yml file version: "3.
