9.5 - Disk/Datastore: Datastore Read Latency change?

Veeam Logoby lando_uk » Thu Dec 15, 2016 2:37 pm

Hi

Since upgrading to Veeam One 9.5, we have been getting "Disk/Datastore: Datastore Read Latency" alerts on random datastores, its happening pretty often, mainly when there's an IO spike, but nothing drastic. Looking at the history its happened 52 times on one datastore, but only started the day we upgraded from 9 to 9.5. Did something change on this monitor? Were the trigger levels lowered or something? It's just that we rarely got these on the older version, if ever.

Thanks

Hi Mark,
Indeed starting from v9.5 you can choose either you want the alarm to be triggered by max., average or min. value of the metric.
Could you check the alarm rule > "aggregation" parameter?
Thanks!

Its currently set to Max. What was it set to in version 9 so I can change it back to that?

It used to be "average".
Change it and check the setting can be saved successfully.

I changed it, but it wont save, it just reverts back to Max when you go back into it, any ideas?
