Monasca-alarms

Alarms for Monasca components

Monasca, an Openstack official project, is a scalable monitoring as a service solution. It monitors services and systems by a push model. The Monasca Agent will collect metrics from each node and push them to the Monasca API. It will then be processed by separate microservices for storing, alarming and notifications. The architecture can be viewed here

This chart adds alarms for the components of Monasca so Monasca can monitor itself. However, some components failing, for example Kafka, will have no alarms generated as the threshold engine requires kafka to be working.

QuickStart

$ helm repo add monasca http://monasca.io/monasca-helm
$ helm install monasca/monasca --name monasca --namespace monitoring
$ helm install monasca/monasca-alarms --name monasca-alarms --namespace monitoring

Introduction

This chart adds Alarms for the components of a Monasca deployment on a Kubernetes cluster using the Helm Package manager.

Prerequisites

Kubernetes 1.4+
Monasca installed using Helm

Installing the Chart

Monasca-alarms can either be installed from the monasca.io helm repo or by source.

Installing via Helm repo (recommended)

$ helm install monasca/monasca-alarms --name monasca-alarms --namespace monitoring

Note: monasca-alarms must be installed in the same namespace as monasca

Installing via source

$ helm repo add monasca http://monasca.io/monasca-helm
$ helm dependency update monasca-alarms
$ helm install monasca-alarms --name monasca-alarms --namespace monitoring

Either option will add the alarms for the components of Monasca on the Kubernetes cluster with the default configuration. The configuration section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release --purge

The command removes all the Kubernetes components associated with the chart and deletes the release.

Default Alarms for components

By default Monasca alarms will be created for Kafka and Zookeeper.

Configuration

The following tables lists the configurable parameters of the Monasca alarms chart broken down by microservice and their default values.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install monasca-alarms --name my-release \
    --set kafka.start_periods=4

Alternatively, a YAML file that specifies the values for the below parameters can be provided while installing the chart. For example,

$ helm install monasca-alarms --name my-release -f values.yaml

Tip: You can use the default values.yaml

Kafka

Parameter	Description	Default
`kafka.enabled`	Kafka alarms enabled	`true`
`kafka.start_periods`	How many periods Kafka is not started before alarming	`3`
`kafka.running_periods`	How many periods Kafka is not running before alarming	`1`

Zookeeper

Parameter	Description	Default
`zookeeper.enabled`	Zookeeper alarms enabled	`true`
`zookeeper.start_periods`	How many periods Zookeeper is not started before alarming	`3`
`zookeeper.running_periods`	How many periods Zookeeper is not running before alarming	`1`
