This monitor catches Xian events that notifies when the Ethernet multiple collisions if has changed its state.
Number of ethernet multiple collisions is over threshold.
The number of successfully transmitted frames that were inhibited by more than one collision is above the maximum threshold configured in Xian Network Manager 2012.
Collisions are acceptable to a point, but can bring your network to a virtual standstill. They are caused by a faulty network adapter where the sensor is failing, a congested network segment, or a network loop.
If the adapter is faulty, replacement is the only option; isolate each adapter to see if the problem stops. With regards to a congested network, segmentation is usually the best option: use a bridge, router, or switch to reconfigure your network into segments with fewer stations. If you identify a network loop, ensure that no redundant connections to the same station have both connections active simultaneously.
Monitors the number of successfully transmitted frames on a particular interface for which transmission is inhibited by more than one collision.
