This documentation is part of the Using Prometheus guide. You can view the complete guide here: How to configure Grafana to use Prometheus as a data source.

👋 Welcome to the Stackhero documentation!

Get started more quickly and save time on setup: a secure Grafana cloud hosting instance is ready in around 5 minutes.

Are you noticing gaps in your Grafana charts? A common cause is a mismatch in scrape intervals between Prometheus and Grafana. Here is how you can address this:

1. Open your Prometheus configuration file and check the global/scrape_interval setting. For Stackhero's Prometheus instance, the default is typically 15s.

1. In the Grafana UI, navigate to Configuration > Data Sources and select Prometheus.
2. Ensure the Scrape Interval in Grafana matches the scrape_interval in your Prometheus configuration.

By aligning the scrape intervals, you can resolve most issues related to missing data points in your dashboards.
