What does Prometheus do?

Prometheus is an open-source monitoring tool that collects metrics (performance data) from applications and infrastructure, stores them in a time-series database, and provides alerting based on threshold rules. It is commonly used in cloud-native environments and with Kubernetes.

How is Prometheus used in the workplace?

DevOps engineers and SREs configure Prometheus to scrape metrics from services and systems. Teams then query Prometheus using PromQL to investigate performance issues, and they pair it with Grafana to visualize metrics on dashboards. They also set up alert rules so the team is notified when problems occur.

Is Prometheus formal or informal?

Prometheus is a proper noun (the name of a specific tool), so it is used formally in technical documentation and spoken discussions alike. In workplace conversations, you refer to it by name: 'Let us check Prometheus,' not 'Let us Prometheus it.'

What is the difference between Prometheus and Grafana?

Prometheus is the backend that collects and stores metrics. Grafana is a separate visualization tool that reads data from Prometheus and displays it on dashboards. They work together but are different tools with different purposes.

Can I use Prometheus as a verb?

No. Prometheus is a noun (a tool), not a verb. You configure, deploy, or use Prometheus, but you do not Prometheus something. Saying 'We Prometheus the system' is incorrect.

Say it like this

✓We need to set up Prometheus to monitor the cluster.

✓Pull up Prometheus and check the metrics for the past hour.

✓The alert fired because Prometheus detected high latency on the API endpoint.

Real examples

in a standup

"I configured Prometheus scrape jobs this morning to collect metrics from all three services."

in a code review

"Make sure your application exposes metrics on port 8080 so Prometheus can scrape them."

in a team meeting

"We should migrate from Datadog to Prometheus because it integrates better with our Kubernetes setup."

Don't say this

Handle with care. Prometheus is a proper noun (a specific tool), not a verb. Do not say 'we Prometheus the system.' Also, it is not interchangeable with generic monitoring tools—always refer to it by name when discussing the specific platform.

✕We Prometheus the database logs.

✓We use Prometheus to monitor the database metrics.— Prometheus is a noun (a tool), not a verb. You use or configure Prometheus, you do not Prometheus something.

✕Prometheus sent us an email alert yesterday.

✓Prometheus triggered an alert that was sent via email yesterday.— Prometheus collects metrics and fires alerts based on rules—it does not directly send emails. Alert managers handle notifications.

✕Is Prometheus the same as Grafana?

✓Prometheus is the monitoring backend; Grafana is the visualization layer we use with Prometheus.— Prometheus and Grafana are different tools that work together. Prometheus stores metrics; Grafana displays them.
