AVD Session host uptime and Automate

Copper Contributor


I am new to Azure monitor and reporting. I have written a KQL query to sum-up a daily uptime for AVD session hosts. When this query runs

1: It is not rounding the availability column.

2: How can I set a start time and end time fixed for a day (12AM till 11:59 pm)

3: I need to automate this daily run and email this report

Could you please give me any guidance on this. I give the screen shot below

1. You can use round(Availability,2) to round a vale to 2 decimal places as an example
2. This is yesterday, the first seen record and the last

| where TimeGenerated between( startofday(ago(1d)) .. endofday(ago(1d)) )
| summarize min(TimeGenerated), max(TimeGenerated)

3. You'll need to look at a Automation Rule and Playbook for that, there are many templates in the Content Hub
Thanks Clive, much appreciated.


I am trying to extract last month report but it is erroring.  Is the query structure for the last month is OK?  Could you please look at this. Thanks in advance.

| where TimeGenerated between (startofmonth(ago(1m))) .. endofmonth(ago(1m)))
| summarize min(TimeGenerated), max(TimeGenerated)
//| summarize heartbeat_per_hour=count() by bin_at(TimeGenerated, 1h, start_time), Computer
| extend available_per_hour=iff(heartbeat_per_hour > 0, true, false)
| summarize Available_Hours=countif(available_per_hour == true) by Computer
| extend Total_Hours=round((max(TimeGenerated) - min(TimeGenerated) / 1h)
| extend Availability_Percentage=Available_Hours * 100 / Total_Hours
| project
round(Availability_Percentage, 0)





The month part is solved with this:


| where TimeGenerated between ( startofmonth(now(),-1).. endofmonth(now(),-1) ) 
| summarize heartbeat_per_hour=count() by bin(TimeGenerated, 1h), Computer
| extend available_per_hour=iff(heartbeat_per_hour > 0, true, false)

Thanks Clive, it worked. Thanks for your help.
