monitoring-lite
A centralised grafana/prometheus/loki stack. This an alternative approach to coop-cloud/monitoring
which does include any of the services which actually gather metrics and/or logs. Instead, this is a useful recipe for folks who need to centralise their monitoring stack into a single grafana/prometheus/loki & several instances of node_exporter/cadvisor/promtail.

Setup
This stack requires 3 domains, one for grafana, prometheus & loki. This is due to the need for the gathering tools, such as node_exporter, to have a publicy accessible URL for making connections. We make use of the internal prometheus HTTP basic auth & wire up an Nginx proxy with HTTP basic auth for loki. Grafana uses Keycloak OpenId Connect sign in. The alertmanager setup remains internal and is only connected with grafana. It also assume that you are deploying the coop-cloud/gathering
recipe on the machines that you want to gather metrics & logs from. Each instance of the gathering recipe will report back and/or be scraped by your central install of monitoring-lite.
Post-setup guide
-
configure prometheus/loki/alertmanager as data sources in grafana under
Configuration > Data sources
- for loki, you need to set a "Custom HTTP Header":
X-Scope-OrgID: fake
- for loki, you need to set a "Custom HTTP Header":
-
configure the SMTP mailer under
Alerting > Contact points
- edit the default contact point, choose "Alertmanager" as type &
http://alertmanager:9093
as URL - use the "Test" button to send a test mail. It should fire a request at the alertmanager & that should send a mail
