Vipr SRM performance alert

I have experience on watch4net version 6.2, but there is much different with new Vipr SRM.

I have several questions:

1. there is "time window" in setting a performance alert, that will calculate the threshold in that period, and prevent to alert when threshold is   

    touched each time.

    example: when the time windows is 60 mins, and the utilization is over threshold  for 3 hours, I will only get 3 alert mails, it make sense

    and work fine in watch4net 6.2

    But in SRM 3.5 , same configuration, I will get alert mail every around 20 mins .....does anyone have idea about performance alert?

2.can device alert(such like failed hardware) also integrate into SRM system and send out an alert mail?

Hhmm.  It should work as you expect if you have "Wait for period" checked and have set the "Window Management" set to 'Reset after output'.

Power, feel free to open a Service Request if this continues to be an issue and we will be glad to look into it in your environment.

Thanks,

Hi,

The behavior desired in item #1 can be achieved by using a "Stateful" Comparator.  We are working on a similar threshold based alert for ESX server and here is a quick snapshot of it -

ESX-CPU-Util-Alert.PNG.png

In this case, the Comparators being stateful (keep the Stateless flag unchecked), will only generate the SNMP trap when the condition is met the first time.

For item #2, you could use the mail action in addition to the SNMP trap action already in place.  Alternatively, Alert Consolidation Email Notification (located in the Alert definitions node) can also be used.


I hope this helps.


Thanks,

hi Gayatri:

thanks you to give me a different hints.

As my example, if the CPU utilization is  over 75% and last for 2 hours, how many alert notification will be created in your definition ?

example 2: if the CPU utilization is  over 75% for about every 10 mins? how many alert notification will be created in your definition?

Hello Power (do pardon me if that's not your first name),

With the alert definition I provided, only 1 alert will be created in both your examples.  The thing to note though is that this alert will remain active with Severity getting updated until the data comes in suggesting that CPU Utilization has gone below 75%, which is when this alert gets cleared.  So, now when you consider the Alerts Dashboard, an active alert indicates a situation (in this case High CPU Utilization) exists, which gets cleared only when the situation's resolved.

Let me know if you had something else in mind...

hi Gayatri:

just call me power...

Your thought is good too, but I have different purpose with yours.

We will not watch dashboard all the time, but monitor the utilization by email.

The purpose I want is that sending a email every 60 mins when the average utilization during this period is over threshold.

in my example:

1.if the CPU utilization is  over 75% and last for 2 hours: I will get 2 email alert

2: if the CPU utilization is  over 75% for about every 10 mins, i will get email alert when the average value is over 75% during last 60 mins; if not, i will not receive an email.

This configuration works fine in watch4net 6.2, but not in SRM 3.5, I don''t know what's the difference.

Ah, I see.  Let me give this a quick try and get back to you, Power.

Hi Power,

Apologies for the delay - we had some network issues yesterday.

So, I gave it a try and it worked for me.  Here is the alert definition -

And the Time Window definition looks something like this -

Is this what you have tried and has not worked?

yes, that's the configuration.

my focus is array controller utilization, and my time windows setting is 60 mins, threshold setting is more than 70%. it always send out mail every 20 mins not 60 mins, so strange.

for example:

SRM3.5

W4N6.2

Hello Power,

Just circling back to check-in with you?  Did your alert definition work to your expectation?  Please let me know if you need any further help.

just verified, changing the "Window Management" setting to 'Reset after output' (default is sliding, and I used it in w4n v6.2), the output looks much like what I want.

Many thanks to Aryan.....
