| I have seen a few questions and/or information about thresholds on the exam (which I failed last week)...however, I am not finding too much info on it in the books I am studying...but I am seeing them in some of the practice questions...can anyone give me a quick overview on what to look for on the exam? thxs

| Under what context are you referring to thresholds? Typically, thresholds are set for servers to alert administrators to issues such as abnormally high cpu utilization (over 70% usage). This may indicate that all the services on the particular server are slowing down performance. | |

| This was referring to SNMP traps with NICs...adjusting the NIC threshold either at .05 MBps, .75 MBps, 1.25 MBps, or 2 MBps before the SNMP sends a trap...Personally, I have never had to use this while I have been in the IT industry (but I work at the desktop level)...I was basically trying to get an idea when you would use this information in a real world environment.. | |

| The small training company I worked at did not implement network monitoring and only had two servers. Anyway, I think Supertech or some of the other guys will be able to chip in some comments regarding their server experiences. Plus, I'm interested in hearing about it too. I'd check back in a little bit. | |

| Thresholds
SNMP uses a MIB (Management Information Base) to manage the router. The MIB includes an extensive collection of statistics (MIB variables) that track the router's performance and provide early warnings of abnormal operating conditions.
With the Site Manager threshold feature, you can configure the agent to automatically notify the network manager when specific statistics (or instances of the variable) reach certain levels.
You can set a threshold for any integer, counter, gauge, or timetick variable in the MIB. Using the threshold parameters, you select the polling interval, which specifies how often the agent checks the statistic to see if its value has reached the threshold. You also set three threshold values (high, medium, and low) and specify the threshold action as Lessthan or Greaterthan.
When the statistic reaches the threshold, the agent generates an event. You specify the severity level at which you want the manager to log the event. Table 11 lists the available severity levels and their suggested meanings. Depending on how you configure the SNMP trap parameters, the agent may also send the threshold exception as an SNMP trap.
Severity Suggested Definition
Info - Indicates routine events that require no action
Warning - Indicates events that occur unexpectedly
Debug - Indicates events that you use to solve network problems
