Grafana is an open-source, general purpose dashboarding tool, which runs as a web application. It can be used to create a variety of time-series graphs and also for displaying logs. It supports Prometheus, graphite, InfluxDB, opentsdb, Grafana Loki, PostgreSQL and many other data sources.
See Grafana options
Installation
Grafana is available as NixOS module, it can be enabled using the following config:
services.grafana = {
enable = true;
settings = {
server = {
# Listening Address
http_addr = "127.0.0.1";
# and Port
http_port = 3000;
# Grafana needs to know on which domain and URL it's running
domain = "your.domain";
root_url = "https://your.domain/grafana/"; # Not needed if it is `https://your.domain/`
serve_from_sub_path = true;
};
};
};
This will make Grafana available only at localhost. On a server, it might be used through SSH tunnel or made publicly available using nginx with TLS. For example the follwing Nginx configuration can be used:
services.nginx.virtualHosts."your.domain" = {
addSSL = true;
enableACME = true;
locations."/grafana/" = {
proxyPass = "http://${toString config.services.grafana.settings.server.http_addr}:${toString config.services.grafana.settings.server.http_port}";
proxyWebsockets = true;
recommendedProxySettings = true;
};
};
Configuration
Everything else (data sources, users, dashboards, ...) can be configured either in the Web UI, or as code.
Via Web UI
Log into the Grafana web application (using default user: admin, password: admin). Refer to the official documentation on how to do it:
Declarative configuration
services.grafana = {
declarativePlugins = with pkgs.grafanaPlugins; [ ... ];
provision = {
enable = true;
dashboards.settings.providers = [{
name = "my dashboards";
options.path = "/etc/grafana-dashboards";
}];
datasources.settings.datasources = [
# "Built-in" datasources can be provisioned - c.f. https://grafana.com/docs/grafana/latest/administration/provisioning/#data-sources
{
name = "Prometheus";
type = "prometheus";
url = "http://${config.services.prometheus.listenAddress}:${toString config.services.prometheus.port}";
}
# Some plugins also can - c.f. https://grafana.com/docs/plugins/yesoreyeram-infinity-datasource/latest/setup/provisioning/
{
name = "Infinity";
type = "yesoreyeram-infinity-datasource";
}
# But not all - c.f. https://github.com/fr-ser/grafana-sqlite-datasource/issues/141
];
# Note: removing attributes from the above `datasources.settings.datasources` is not enough for them to be deleted on `grafana`;
# One needs to use the following option:
# datasources.settings.deleteDatasources = [ { name = "foo"; orgId = 1; } { name = "bar"; orgId = 1; } ];
};
};
environment.etc = [{
source = ./. + "/grafana-dashboards/some-dashboard.json";
group = "grafana";
user = "grafana";
}];
