Hello -
We are hosting our image server in Azure and we use image re-sizer plugin. We have set-up an alert rule on DISK WRITE BYTES/SEC to send an alert if greater than 15 MB. I keep getting alerts even when DISK WRITE BYTES/SEC never came close to 15 MB. When I see the performance counter graph in management portal, it shows the counter never crossed the threshold limit set.
We are not able to determine if the management portal is showing incorrect data when our process is indeed doing more than 15 MB Disc Writes/sec or if we are getting false alerts. Can someone please help?
