What is ddev-grafana?

This repository provides Grafana stack addon to DDEV.

It contains several components from Grafana stack:

• Grafana: an open source analytics and interactive visualization web application. It provides charts, graphs, and alerts for the web when connected to supported data sources.

• Prometheus: an open source monitoring solution written in Go that collects metrics data and stores that data in a time series database.

• Loki: a horizontally scalable, highly available, multi-tenant log aggregation solution.

• Tempo: an open source, easy-to-use, and high-scale distributed tracing backend.

Be aware that this addon uses a lot of port mapping, so port numbers may overlap with another running ddev project or local apps, that can lead to startup errors, and even hidden errors with "503: No ddev back-end site available" if the same port is configured with HTTP on one project and HTTPS on another, here is the issue about this: ddev/ddev#4794

To resolve such issues try to find the conflicting port and comment it or change the port number to a free one.

Installation

1. In the DDEV project directory launch the command:

ddev get MurzNN/ddev-grafana

2. Restart the DDEV instance:

ddev restart

3. Open the Grafana web interface via the url: https://your-project-name.ddev.site:3000/

Customizations

If you need to run several projects with Tempo OpenTelemetry collectors, with default settings it will fail, because several projects can't use the same port number on the host network. To fix this you should disable mapping ports to the host network on the second project via renaming the file docker-compose.grafana.host-ports.yaml to docker-compose.grafana.host-ports.yaml.disabled, or change port numbers to unique ones, and restart the projects.

If you want to disable binding Grafana services to the localhost, rename the files:

• docker-compose.grafana.localhost.yaml to docker-compose.grafana.namedhosts.yaml.disabled
• docker-compose.grafana.namedhosts.yaml.disabled to docker-compose.grafana.namedhosts.yaml

If you need to expose non-HTTP ports (gRPC, etc), you can uncomment them in the docker-compose.grafana.localhost.yaml file.
