fping command understanding: reg

[Manukumar NM]

Greetings...

                    Dear team members,

                                                      I have doubt in fping command for doing ping check, when ever server sends ping, each ping process runs independently and sends a request to the it's assigned ip's address OR  it sends one request, waits for a response or timeout, and then sends the next request. Just I want to understand it's run simultaneously or parallel. 

Thanks in advance

Each task sends a ping to one specific device, if there's a timeout it will be retried according to the configuration.

The default configuration is here:

https://github.com/openwisp/openwisp-monitoring/blob/master/openwisp_monitoring/check/classes/ping.py#L20-L41

(Count: 5, Interval: 25, Timeout: 800, consult the fping help for more information about each option).

There can be multiple processes running ping tasks, so multiple ping operations can be performed simultaneously, but they act on different devices.
Each ping task operates only on 1 device.
