Did you get this working?   If not, check this first 

 

 

// check to see which resource providers you have
AzureDiagnostics
| where TimeGenerated > ago(7d)
| summarize by ResourceProvider

If you add a count() to the above, you can see how many records you have by each ResourceProvider

 

Then, your query should work (adjust the days/hours to suit)

 

 

AzureDiagnostics
| where TimeGenerated > ago(1d)
| where ResourceProvider == "Microsoft.DBforMySQL"

    ThanksCliveWatson.

     

    I am able to get the logs for MySql database in Azure Log Analytics workspace now and i have written a query to get the failed connections details. below is the query

     

    AzureDiagnostics
    | where SubscriptionId != ""
    | where TimeGenerated > ago(10m)
    | where ResourceProvider == "MICROSOFT.DBFORMYSQL"
    | where Category == "MySqlAuditLogs" and event_class_s == "connection_log"
    | where event_subclass_s == "DISCONNECT"
    | summarize logoncount= count(), TenantId=arg_max(TenantId, SubscriptionId, ip_s, TimeGenerated, LogicalServerName_s, db_s, ResourceGroup)
    | where logoncount > 3
    | project TenantId, SubscriptionId, ip_s, logoncount, TimeGenerated, LogicalServerName_s, db_s, ResourceGroup

     

     

    but the issue which i am facing in the query is it is just giving me over all DISCONNECT counts and i need help in modifying the filter to get the failed connection count.

      Hi Syed_Aman 

      I don't have any DBforMYSQL records 

       

      AzureDiagnostics
| where SubscriptionId != ""
| where TimeGenerated > ago(10m)
| where ResourceProvider == "MICROSOFT.DBFORMYSQL"
| where Category == "MySqlAuditLogs" and event_class_s == "connection_log"
| summarize count() by  event_subclass_s

       

      The above should enable you to see what other states, like 'failed' have occurred - sorry I don't have the data so this is a guess!
