CodeQL Dependency Review

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

Add URLs to check

To add a URL to minitoring is pertty simple. Create settings.yml to add your endpoints to monitor. See an example of settings.yml below

opegenie:
  enabled: false
email:
  enabled: true
groups:
- name: prod
  emails:
     - reviceremail@gmail.com
     - reciver@yahoo.com
- name: dev
  emails:
     - reviceremail@gmail.com
     - reciver@yahoo.com
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

Run the Code

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 disbled 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="youremail@server.com" #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"
