lib_alert_tree
Python library¶
This Python library serves as a common ground when composing Prometheus alerts into hierarchical trees in a form that can be best consumed by user interfaces and monitoring tools.
It features an optional helper to generate a command-line tool which helps with discovery of an existing tree, and provides an easy command to render a corresponding PrometheusRule manifest.
Overview¶
The library only has a handful of modules:
lib_alert_tree.models
¶
The main module you will use to build the desired hierarchy of alerts, through
the use of ExistingAlert
and DerivedAlert
.
lib_alert_tree.prometheus
¶
Holds the data containers used to render accurate Prometheus configuration.
lib_alert_tree.kubernetes
¶
Provides some helpers for listing common existing alerts for some usual K8s
objects (e.g. deployment_alerts
will list all alerts for a Deployment,
given its name and namespace).
lib_alert_tree.cli
¶
Exposes the generate_cli
method, which can be used to define a Click
entrypoint, with helpful subcommands for interacting with one or more alert
trees.
