Grafana Cloud Cost & Alerting Overhaul

Overview

Runaway metric ingestion was driving roughly $1,090/mo in Grafana Cloud overages, and alerting was slow and noisy. I audited every cost driver, cut what didn't need to be there, and rebuilt alerting around a fast, deduplicated pipeline.

The problem

Runaway metric ingestion was driving roughly $1,090/mo in Grafana Cloud overages, and alerting was slow and noisy, so incidents were noticed late and buried in email.

What I did

1. 1

   Audited every metric and log stream feeding Grafana Cloud to find what was actually driving cost.

2. 2

   Reduced or re-tuned the expensive cost drivers and moved heavy usage to cheaper alternatives.

3. 3

   Built a Python Loki to Slack alerting pipeline, hosted on Azure Functions behind a custom API, with deduplication and suppression windows plus a manual-review web UI.

4. 4

   Authored 30+ Grafana alert rules routed to Slack and email, replacing noisy email-only alerting.

Tech used

Outcomes

• Cut Grafana Cloud spend roughly 71%, from about $1,090/mo overage to about $316/mo.

• Incidents surface faster with far less noise thanks to deduplicated, suppressed alerting.
