Configuring Dell OpenManage IT Assistant to Monitor Your Systems 109
Selecting An Appropriate Discovery Time-Out Value for the Network
Since Tom is monitoring remote systems across a WAN, time-out values may
differ significantly between local systems and those further removed. In this
case, it is recommended that Tom determine and set an appropriate time-out
for the discovery of the systems located over the WAN.
In environments with long network latency times, such as global WANs, Tom may
want to consider increasing ping time-outs across the enterprise. He can
determine the ping times of systems that exhibit the greatest latency on the
network by using the To ol sTr oubl esho ot ing Tool and selecting the
Device Connectivity tab. From there, Tom can test the connection of
high-latency systems to see whether he should increase specific ping times
for better WAN performance.
