Have you considered disabling the hardware alerting and / or altering the thresholds in Advanced Alert Manager?
I'm not sure entirely what you want the system to do.
You could alter the actions on the hardware monitoring alert to only alert if the status is Critical (or whatever threshold you want)
You could alter the alert to log an event to the event log, but only raise an alert if a certain status is reached.
You could disable hardware alerting completely.
... or any combination of the above and much more.
i was hoping to keep monitoring the Fans but would like to allow for fluctuations in fan speed so i do not get an alert when the fan kicks into high gear..I should be able to adjust for a specific length of time that the fan stays in high speed before sending out an alert. is this correct? If so would you have an example?
You can edit the alert to not trigger until the condition has existed for XX minutes / seconds from within advanced alert manager. I'm not able to access advanced alert manager at the moment, or I'd upload some screenshots.
Unless you had SAM before the Hardware Health Monitor was just added to your system with the 10.4.x upgrade. This means the canned alerts that came with the upgrade are now firing.
What you will want to do is go into your Advanced Alert Manager (I assume you are using Advanced and not Basic alerts?) and find the Hardware Health Monitor alert.
You have a couple options here. You can add the "do not trigger until condition has existed for xx minutes" as suggested above, or you can go into the trigger actions and simply change the thresholds listed there for the trigger conditions. Or, if you want certain devices not be alerted on you can use the "alert suppression" tab to exclude individual or groups of nodes. Changing the alert or even turning it off will not turn off the Hardware Health Monitor for devices so that information will still be shown on the Node Details pages, making changes to the alert will only affect how you are alerted about the changes. (just making that clear).
Matt provided some other great suggestions above as well, such as turning of Email actions if you prefer to keep the current thresholds and only have them logged in your NetPerfMon log.
Hopefully that helps a little too.
