I want to query a specific log analytics workspace for an IP address .

You could do a simple (but inefficient) search - please edit to match your IP address.

search "192.168"


If you know the Table that contains the data that really helps?  This next query brings back all the Tables that contain the IP address, if you don't already know them, that way we can now just search within a Table to improve the query time efficiency.


search "192.168"
| summarize count() by Type 


The results of query #2, the Type Column list the Tables that have 192.168* in them.

Type count_
WindowsFirewall 97742
NetworkMonitoring 125670
AzureNetworkAnalytics_CL 40


Now we know the three Tables that have that IP Address, you can just get (for example) 10 rows of data that match that IP.  


| search "192.168"
| limit 10


Results of Query 3 (I just show one row for clarity):

I can see 3 columns that have that data, you don't say what you want to do with it when found, maybe something like this, which filters on a particular column (DestinationIP) again improving the query execution?

| where DestinationIP  == ""
| summarize count() by Computer 


 Run the above query from here: Go to Log Analytics and Run Query




thank you for hyour help. The query can be simple and broad or granular. Also is there a default workspace associated withthe MS Azure security center widget. Where you can see all security alerts for your instance. Where are those logs stored? or is unique for each setup?
