How to get stats count value as 0, if there are no events for that value in splunk search.

[guptap2]

We have 7 different filetypes, we are trying to get count of each filetype in table. If count of any of them is 0, it should be displayed, but somehow in my query it is removing the row of the filetype having count 0.

Query :
index=sap_bam sourcetype=sap_d059 earliest=-6h filetype=Billing OR filetype=SalesOrder OR filetype=Clearing OR filetype=Delivery OR filetype=ReturnOrder OR filetype=M39COGSSIT OR filetype=M39AcutualRevenueRec
| dedup source
| eventstats count by filetype
| dedup filetype
| rename count as filecount
| eval alertme=if((filecount=0) OR isnull(filecount),1,0)
| fields sourcetype filetype filecount alertme
| table filetype filecount alertme

Result is :

alertme filecount filecount
SalesOrder 6 0
Billing 6 0
Delivery 6 0
ReturnOrder 6 0
Clearing 5 0
M39COGSSIT 3 0

try this

| stats count 
| eval filetype="Billing,SalesOrder,Clearing,Delivery,ReturnOrder,M39COGSSIT,M39AcutualRevenueRec" 
| makemv delim="," filetype 
| mvexpand filetype 
| append 
    [ index=sap_bam sourcetype=sap_d059 earliest=-6h filetype=Billing OR filetype=SalesOrder OR filetype=Clearing OR filetype=Delivery OR filetype=ReturnOrder OR filetype=M39COGSSIT OR filetype=M39AcutualRevenueRec 
    | dedup source] 
| stats sum(eval(if(isnull(_time),0,1))) as filecount by filetype 
| eval alertme=if(filecount=0,1,0) 
| table filetype filecount alertme
