Manage data integrity: Would erasing a single log would impact the "integrity" of the logs causing a failure on the integrity check?

Hi all,

I had configured the data integrity on index=index_test of my Splunk infrastructure following the instruction on https://docs.splunk.com/Documentation/Splunk/6.3.3/Security/Dataintegritycontrol

Now I have the l1Hashes and l2Hash files as expected and I deleted, for testing, a single log from the index_test (from GUI whit "delete" command). But after performing a check-integrity command

 ./splunk check-integrity -index index_test 

I have no "failure", all check goes ok.
Is this an expected behaviour? My expectation was that erasing a single log would impact the "integrity" of the logs causing a failure on the integrity check. I'm missing something? Someone has experiences on this topic?

Thanks very much,
Gabriele

That’s not what the “delete” command does. It doesn’t truly delete anything. It marks events as not searchable. File system hashes are meant to catch OS level changes outside of Splunk.
