Program drawing given server response time on chart. Pinging of the hosts is done using call of ping command from operating system and parsing output.
Create small application which will ping given address, draw plot with responses times over time and will log data to file (one log file per day).
Given as offline interview task.
Input:
Editable fields:
- host IP - IP of host to ping
- timeout value - max time which ping command should wait for answer in milliseconds,
- interval value - frequency of pings in seconds.
Output:
Plot with ping response statistics over time.
This section describes briefly how to setup environment and build project.
C++ compiler with C++17 support as a minimum and CMake 3.8+. As application is based on Qt you will also needed it to build this application.
Use QtCreator or Cmake.
| Tool | Windows 10 | Lubuntu 20.04 |
|---|---|---|
| GCC | 7.3.0 | 9.3.0 |
| Cmake | 3.14 | 3.17 |
| Git | 2.20 | 2.25 |
| QtCreator | 4.12.0 | 4.13.0 |
Pick one host and get its IP (you can use ping -a <name> command in console). Copy IP address into application field Address. Optionally change Timeout field value to adjust time which ping command will wait for answer from address. Also optionally modify Interval field value to change frequency of calling system ping command. if all fields are as intended, than hit ping button to start pinging. Click it again to stop.
There might be few seconds of delay between clicking ping/stop button and reaction. It is a result of system ping command which needs time to perform its job.
