Statusetat

status page with very HA in mind and notification system to send information about incident(s) or scheduled task(s) to external system like slack, email or whatever plugin you implement.

Features:

• Easy admin web interface to manage incidents and scheduled tasks
• Send notifications to external system (slack, email, plugins...) when incident come
• Full rest api to create/read/update/delete incident/scheduled tasks
• Subscribes systems

Why another status page ?

A status page must be more resilient than the service you want to be monitored because you need to have the page always available even when your a part of your infra is partially down to give the information to your client.

When you're a hosting service be more resilient on your status page become complicated. This implementation allow you to set multiple storage system in same time to ensure you always can store/retrieve incidents and scheduled tasks.

Statusetat will replicate in all storage what you write and ensure that the data can be retrieved.

For customize content of email you can see data passed to template at https://github.com/orange-cloudfoundry/statusetat/blob/master/notifiers/email/email.go#L223-L236 and template function available at https://github.com/orange-cloudfoundry/statusetat/blob/master/extemplate/template.go#L25-L51

Plugin

You can create a plugin for notification for your own need.

Plugin are grpc golang plugin which doc can be found here: https://github.com/hashicorp/go-plugin .

You must implement plugin.Notifier.

Example of implementation:

package main

import (
	pluginhc "github.com/hashicorp/go-plugin"
	"github.com/orange-cloudfoundry/statusetat/config"
	"github.com/orange-cloudfoundry/statusetat/models"
	"github.com/orange-cloudfoundry/statusetat/notifiers/plugin"
	log "github.com/sirupsen/logrus"
	"strings"
)

type LogNotifier struct {
}

func (n LogNotifier) PreCheck(incident models.Incident) error {
	return nil
}

func (n *LogNotifier) Init(baseInfo config.BaseInfo, params map[string]interface{}) error {
	return nil
}

func (n LogNotifier) Name() (string, error) {
	return "log_notifier", nil
}

func (n LogNotifier) Id() (string, error) {
	return "log_notifier1", nil
}

func (n LogNotifier) MetadataFields() ([]models.MetadataField, error) {
	return []models.MetadataField{}, nil
}

func (n LogNotifier) Notify(notifyReq *models.NotifyRequest) error {
	log.
		WithField("subscribers", strings.Join(notifyReq.Subscribers, ", ")).
		WithField("triggerred_by_user", notifyReq.TriggerByUser).
		Info(notifyReq.Incident)
	return nil
}

func main() {
	pluginhc.Serve(&pluginhc.ServeConfig{
		HandshakeConfig: plugin.Handshake,
		Plugins: map[string]pluginhc.Plugin{
			"notifier": &plugin.NotifierGRPCPlugin{
				Impl: &LogNotifier{},
			},
		},

		// A non-nil value here enables gRPC serving for this plugin...
		GRPCServer: pluginhc.DefaultGRPCServer,
	})
}

You can build it with command line go build -o log-notif .

You can now use it in your config with:

• Type name: plugin or notifier name you have set in func signature Name() string
• Params:

# path to .so to load
# in our example it would be `./log-notif`
path: <string>
# all remaining arguments will be pass at Init

This project was heavily inspired by statusfy mostly on the design part and models of incidents/components.

Cachethq is another source of inspiration for some details on the admin design part.
