The frequency of the diagnostic settings depends per service and logs. Usually for most metrics is every 1 minute at lowest. Diagnostic logs do not have consistent frequency as they are available when actual log is generated. I do not see why you would have requirement for 1 second frequency of metrics. First it will be way more expensive to retain those and second there is no alerts that can act every second.

Hi @Stanislav Zhelyazkov .. thanks for your detailed answer regarding the query .
Yes you are right not every metrics has consistent frequency and also I found that some of metrics could be collected for lowest sample rate of 10 second.
Our requirement of 1 second frequency came up for Performance Testing and metrics will not be retained longer but for the duration of performance Testing only. Also alerts will not be required as it will be monitored by people throughout the duration .

Our resources have used monitoring tools like Sitescope and Dynatrace earlier and looking for similar option for runtime monitoring.

No matter which third party monitoring software you are looking at those will still be using Azure Monitor metrics as bases for their monitoring so the result will be the same.
