Sky-meter is a synthetic endpoint checker. You can deploy this on your infra run checks from your infra and set alerts. Here we are using the go httptrace library.
Currenly I have added Database support. The endpoints and HTTP output are now being saved in the Database. We also have a sentry integration to catch the runtime errors. Development is in progress

I have integrated SMTP and Opsgenie, more integrations are in the pipeline Currently, the project is under development. You may have to experience some glitches at this moment.

GO version: 1.18
Postgres: 15.0

• Ubuntu 22.10
• alpine(docker)
• macOS

We highly recommend running the app as a docker container. See Docker Hub Image

To add a URL to monitoring is pretty simple. Create settings.yml to add your endpoints to the monitor. See an example of settings.yml below

opegenie:
  enabled: false
email:
  enabled: true
groups:
- name: prod
  emails:
     - [email protected]
     - [email protected]
- name: dev
  emails:
     - [email protected]
     - [email protected]
domains:
- name: https://skywalks.in
  enabled: true
  timeout: 10
  skip_ssl: false
  frequency: 10
  group: dev
- name: https://sky-meter.skywalks.in
  enabled: true
  timeout: 10
  skip_ssl: false
  frequency: 60
  group: dev
- name: https://github.com
  enabled: true
  timeout: 10
  skip_ssl: false
  frequency: 60
  group: prod

- name: https://githcccubs.com
  enabled: true
  timeout: 10
  skip_ssl: false
  frequency: 60
  group: prod

timeout : Timeout of request in Millisecond (int)
skip_ssl: set flase if you want to skip the ssl verification (bool)
frequency: frequency of health check in secont (int)
group : Group settings

Clone the code

$ git clone https://github.com/sooraj-sky/sky-meter.git
$ cd sky-meter

Run the Postgres docker container (skip this step if you already have a database)

$ docker-compose up -d

Export ENV variables (Sentry will work only in dev mode)
If Email is disabled on settings.yml the following variables are not needed.

1. EmailPass
2. EmailFrom
3. EmailPort
4. EmailServer

SentryDsn is only needed when Mode=dev

$ export DnsServer="8.8.8.8" #requied  
$ export DbUrl="host=localhost user=postgres password=postgres dbname=postgres port=5433 sslmode=disable"  #requied          
$ export EmailPass="your-pass-here" #requied when Email is Enabled  
$ export EmailFrom="[email protected]" #requied when Email is Enabled     
$ export EmailPort="587" #requied when Email is Enabled     
$ export EmailServer="smtp.server-address-here.com" #requied when Email is Enabled   
$ export OpsgenieSecret="your-opsgenie-key-here" #requied when Opsgenie is Enabled on settings.yml
$ export Mode="dev"  
$ export SentryDsn="your-DSn-key-here" #requied when Mode="dev"           

Run the project

$ go run cmd/main.go  

Here I am using concourse CI for the Main Branch

For release branch, I have GitHub Actions
