RC Connectivity Check tools

This PIP package measures the latencies to various hosts and provides statistics such as failure rates and latencies.

Installation

pip install rc_connectivity_check

Usage

Just run rc-connectivity-check

Also accepts an optional --timeout flag to increase request timeouts:

usage: checker.py [-h] [--timeout TIMEOUT]

RevenueCat Connectivity Check tool

options:
  -h, --help         show this help message and exit
  --timeout TIMEOUT  Request timeout, in seconds (default: 5)

Example output (simulating an error):

There were some connectivity failures!
Please help us investigate by following the next steps:

1: Check network routes:
  - Install mtr:
    - macOS: brew install mtr
    - Ubuntu: sudo apt-get install mtr
  - Run mtr using the following command:
    sudo mtr --report -n --tcp --port=443 --gracetime=5 --timeout=5 <broken_ip>

2: Capture network traffic while running this script:
  - In one terminal run:
    - On macOS, over WIFI:
      tcpdump -i en0 -w rc_connectivity_check.pcap -s 0 tcp and port 80
    - On macOS, over ethernet:
      tcpdump -i en1 -w rc_connectivity_check.pcap -s 0 tcp and port 80
    - On linux, find the interface name with ifconfig and use:
      tcpdump -i <INTERFACE> -w rc_connectivity_check.pcap -s 0 tcp and port 80
  - In another terminal, run this script again:
    rc-connectivity-check
  - Once completed, stop the tcpdump process with `Ctrl+C`
  - Send the resulting rc_connectivity_check.pcap file to RevenueCat support
