Alermanager can handle different types of relations in the provides side and in the requires side.
Provides
Alerting
alerting:
interface: alertmanager_dispatch
Over the the
alertmanager_dispatch
relation interface Alermanager can be related to charms that can forward alerts to it,
for example: Prometheus, Loki.
juju relate alertmanager-k8s:alerting prometheus-k8s:alerting
Karma dashboard
karma-dashboard:
interface: karma_dashboard
The karma_dashboard
relation interface links an entire Alertmanager cluster to a
Karma dashboard.
Scaling alertmanager would automatically cause karma to group alerts by
cluster.
juju relate alertmanager-k8s:karma_dashboard karma-k8s:karma_dashboard
Self metrics endpoint
self-metrics-endpoint:
interface: prometheus_scrape
This Alertmanager charm may forward information about its metrics endpoint and associated alert rules to a Prometheus charm over the self-metrics-endpoint relation using the prometheus_scrape interface. In order for these metrics to be aggregated by the remote Prometheus charm all that is required is to relate the two charms as in:
juju relate alertmanager-k8s:self-metrics-endpoint prometheus:metrics-endpoint
Grafana dashboard
grafana-dashboard:
interface: grafana_dashboard
Over the grafana-dashboard relation using the grafana-dashboard interface, this Alertmanager charm also provides meaningful dashboards about its metrics to be shown in a Grafana Charm .
In order to add these dashboards to Grafana all that is required is to relate the two charms in the following way:
juju relate alertmanager-k8s:grafana-dashboard grafana-k8s:grafana-dashboard
Grafana Source
grafana-source:
interface: grafana_datasource
This charm may provide a data source to Grafana through the grafana-source relation using the grafana_datasource interface.
juju relate alertmanager-k8s:grafana-source grafana-k8s:grafana-source
Requires
Ingress
ingress:
interface: ingress
limit: 1
Interactions with the Alertmanager charm can not be assumed to originate within the same Juju model, let alone the same Kubernetes cluster, or even the same Juju cloud. Hence the charm also supports an Ingress relation.
Alertmanager typically needs a “per app” Ingress. The ingress relation is available in the traefik-k8s charm and this Alertmanager charm does support that relation over ingress interface.
juju relate alertmanager-k8s:ingress traefik-k8s:ingress
