Help with a query

Hi All

I have this query

index=checkpoint sourcetype=opsec:anti_virus OR sourcetype=opsec:anti_malware Protection_Name=* NOT action=blocked NOT te_action=block | stats count dc(Protection_Name),values(Protection_Type),values(Destination_DNS_Hostname),values(te_action),values(malware_action),values(file_name),values(file_md5),values(dest),values(Protection_Name) by src | `map_notable_fields` | rename values(Protection_Type) as \"Protection_Type\",values(Destination_DNS_Hostname) as \"Name_Resolved\",values(te_action) as Action,values(malware_action) as \"Malicious_Intent\",values(file_name) as \"File_Name\",values(file_md5) as \"File_Hash\",values(dest) as Dest,src as Source,values(Protection_Name) as \"Protection_Names\",dc(Protection_Name) as \"Infection_Count\"| where Infection_Count>1 | table \"Infection_Count\",Source,\"Protection_Names\",\"Protection_Type\",Dest,\"Name_Resolved\",\"File_Name\",\"File_Hash\",\"Malicious_Intent\",Action"

how can i know how much notable events i will get historical by hour?

I mean not a query over the last 2 hours, but a query every 2 hours for the last month. In other words, if they run the rule every 2 hours, how many notables per day should they expect?

I tried to do that but its not working:

|gentimes start=-20 end=0 increment=1d | map maxsearches=90 index=checkpoint sourcetype=opsec:anti_virus OR sourcetype=opsec:anti_malware Protection_Name=* NOT action=blocked NOT te_action=block | stats count dc(Protection_Name),values(Protection_Type),values(Destination_DNS_Hostname),values(te_action),values(malware_action),values(file_name),values(file_md5),values(dest),values(Protection_Name) by src | `map_notable_fields` | rename values(Protection_Type) as \"Protection_Type\",values(Destination_DNS_Hostname) as \"Name_Resolved\",values(te_action) as Action,values(malware_action) as \"Malicious_Intent\",values(file_name) as \"File_Name\",values(file_md5) as \"File_Hash\",values(dest) as Dest,src as Source,values(Protection_Name) as \"Protection_Names\",dc(Protection_Name) as \"Infection_Count\"| where Infection_Count>1 | table \"Infection_Count\",Source,\"Protection_Names\",\"Protection_Type\",Dest,\"Name_Resolved\",\"File_Name\",\"File_Hash\",\"Malicious_Intent\",Action

What can I do?

Thanks

It's impossible to estimate how many notable events any search will produce without knowing the data being searched. In this example, the number of notable events to expect is roughly equal to the number of malware events reported by CheckPoint.

The test query is failing in part because the gentimes command does not generate the fields expected by the search. It is also failing because the map command does not include the search option.
