Issue/Introduction

Problem:

The net_conenct probe is generating numerous package loss alarms but we can successfully ping the server from the robot where the net_connect probe is running.

 

Environment:

Any release that contains net_connect probe.

 

Cause:

The "delay_between_packet_to_send" setting for each device in the "net_connect.cfg" profiles section defines the delay between successive packets sent in milliseconds.  If this value is too small and the response to a packet sent is not received by the probe in the configured time, the packet is marked as a loss.

 

Resolution:

If "Packets to send = 10" and "delay between packets = 30000ms" then the time taken to send all the packets including delay time = 5min (30000 ms * 10 = 300000 ms = 300 sec = 5min).

In this case, if the check interval is set to less than the expected time (5 mins), then jitter, packet loss, and latency won’t be calculated.

Environment

Release:
Component: UIMNCN
