BeePing v0.5.0

previously named pingmeback

It forage the servers and brings the metrics back to the hive

BeePing is a distant http check as a Service. Call the very simple API, BeePing will measure website for you.

🇺🇸💚 200 OK - 119 ms
📖 DNS - 9 ms
🔄 TCP - 6 ms
🔒 TLS - 52 ms
🖥 Server Processing - 43 ms
🔽 Transfer - 6 ms

Features:

• Very simple JSON API
• Lot of metrics
• Timeline of HTTP request
• SSL Expiration check
• Server SSL/TLS version and Ciphers
• Pattern check (search for text in response)
• GeoIP resolution
• Single binary

Big hugs to :

• Dave Cheney for his inspirational work on httpstat
• Taichi Nakashima for his work on httpstat lib go-httpstat

Install

Download latest version on releases page

• chmod +x beeping
• sudo mv beeping /usr/bin
• beeping

$ ./beeping -h
Usage of ./beeping:
  -geodatfile string
        geoIP database path (default "/opt/GeoIP/GeoLite2-City.mmdb")
  -instance string
        beeping instance name (default hostname)
  -listen string
        The host to bind the server to (default "127.0.0.1")
  -port string
        The port to bind the server to (default "8080")
  -tlsmode
        Activate SSL/TLS versions and Cipher support checks (slow)

Notes

• If no GeoIP database is found, BeePing omit geo response silently
• TLSMode returns more infos on SSL object. It tries the more ciphers and TLS version Golang can test but the checks can be way slower.

Optional

You can plug MaxMind GeoIP file to know on which country the pings goes.

• If pattern is not filled http_body_pattern is always true
• If header is not filled http_header is always true
• ssl is omitted when http://. The same for the tls_handshake field
• geo is omitted if geoip is not set

Error Handling

beeping returns HTTP 500 when check fail. The body contains the reason of the failure.

{
  "message": "Get https://mysite.com/health: net/http: request canceled (Client Timeout exceeded while awaiting headers)"
}
