gochecks package provides utilities to check services health and publish events. It is written fully in Go.

It includes:

checks scheduler

various checks:
- Tcp port
- ICMP/Ping
- http
- snmp get
- rabbitmq queue len
- Arris C4 CMTS temp
- JunOS devices cpu usage and temp
- MySQL connectivity
- Jenkins jobs status
Publishers:
- RabbitMQ / AMQP

Install

go get github.com/aleasoluciones/gochecks

Sample code

Create a Checks Engine with two publisher (rabbit and log)

checkEngine := gochecks.NewCheckEngine([]gochecks.CheckPublisher{
    gochecks.RabbitMqPublisher("amqp://localhost", "events"),
    gochecks.NewLogPublisher(),
})

Add a periodic (20 seconds) http check with up to three retries, tagging the result as production and adding some attributes.

checkEngine.AddCheck(
    gochecks.NewHttpChecker("golang", "http", "http://www.golang.org", 200).
      Attributes(map[string]string{"version": "1", "network": "google"}).
      Tags("production").
      Retry(3, 1*time.Second),
    20 * time.Second)

Development

To pass the integration tests you need to execute a MySQL server, a Postgres server and a RabbitMQ Server and export the corresponding vars.

The directory dev/ offers two scripts and an environment file to achieve this easily:

source dev/env_develop
dev/start_gochecks_dependencies.sh
go test -tags integration -v ./...
dev/stop_gochecks_dependencies.sh

Todo

Metric for all the checks
