Vipr SRM - Status or Replication report
I am working on a report that monitors data received or transmitted on an array that is a target of replication. ie. MB/s received by the target array for a Replicated device. I have set thresholds to indicate status.. green is data is being transmitted, so any value greater than zero, and red data was not transferred, so value = 0. My problem is, when a device is deleted and there is no numeric value, so it would be a NULL until that device is considered a non active metric in SRM. In my report that type of condition is represented by the last known value and never changes. My report polling is Last Day, 1 Hr, Last.
I want to be able to show that in my report by using a threshold so it is investigated. I am using the Status report type. Does anyone know of a way to set a threshold to NULL
Or has anyone created a report that they use to show replication status, VMAX, Recoverpoint, Netapp...
Thanks
Lisa

Hi Lisa,
Have you tried using the "util.ReplaceNan*" formula; you should be able to replace the NULL values with 0

Hi Isaka,
Yes that did resolve the issue with NULL values.. Thanks.
Another observation is for this particular volume replication was stopped. I added the formula util.ReplaceNan to my report and now for the 1 day/realtime/average I see the values are 0. But at the layer up, where I have a status bubble - it is showing the last transfer value of 435MB instead of 0. This level report is set to last day/1 hr/last.
I thought if it polled the last 1 hr = which is 0 that is what should be represented on the status report.
Any idea?

Hi Lisa,
There's a few things that can explain this difference;
The selected period :
Current day is the current calendar day eg.:Sept 5 00:01 to Sept 5 00h00
Last day is the previous 24 hours period eg.: Sept 4 09:00 to Sept 5 9h00
Previous day is the previous calendar day: eg.: Sept 4 00:01 to Sept 4 00h00
So when you are looking at last day 1 hour aggregate last; you are looking at the last hourly aggregated value of the previous day... which can differ from the current day real time average.

Hi Isaka,
Thanks for detailing that out, I believe I had a handle on those polling's.
My intent it the following: Show the status of Replication (metric is throughput) over the last 24, taking the last hourly aggregate and representing that value ( last 1 hour aggregate) in a status bubble report by volume. So if I am looking at the last day - 9/5 09:00 to 9/6 09:00 I should see the last HR aggregate reading reflected in the status bubble so 9/6/ 08:00 to 09:00 time period, correct?
I have a volume that the underlying graphic shows "0" throughput for the LAST 1 HR, but my status bubble does not reflect that. The bubble shows the last positive value of throughput, which happened 8 hrs prior to "0" throughput.
Thanks
Lisa
