I have repeatedly issue with network latency , I want to analysis it only when the issue will come, but before i run Wireshark , issue will get resolve, what can i do in this case how to analysis then.

Can somebody help me here on this, so that i can only monitor it at the time of issue occurs , i don't want to run wireshark all time. It should be only for specific time.

Assuming you have a known network interface where you can capture this behaviour, what you can do is run dumpcap, not Wireshark, in ring buffer mode. That will capture the traffic which you can then pick up when the event is reported. Running dumpcap will not analyse the traffic, so won't blow out of memory when running for a long time. Tweak the ring buffer parameters to your needs, i.e. capture file sizes you can handle, retention time, available storage size, etc.
