I downloaded sysmon from https://docs.microsoft.com/en-us/sysinternals/downloads/sysmon

I tried many times installation and uninstallation, and it still doesn't show any EID:22, yes, I did visit many many urls from chrome.

Does anyone has the same confusion?

Same here, I presume you enabled the DNS Client Events logs? I did and still no Event ID 22 in Sysmon logs. I've been hacking at it a bit of the day. I've not worked with Sysmon configs in the past and figured I was just messing something up (or forgetting to enable something).

Hello This was reported to us by a customer earlier today and in their environment at least was caused by a comment immediately after the RuleGroup Element

sha256,sha1,IMPHASH And was resolved by removing the comment line above. If this fails to resolve the issue in your environment could you email your config to marcook@microsoft.com and I will take a look for you. Regards Mark Cook (MSFT)

my OS is win7, and config file loaded is z-AlphaVersion.xml , but no any DNS query event logged. i didnot find "sha256,sha1,IMPHASH" which commented by @analyze-v in z-AlphaVersion.xml , so that the issue still there,

Sorry that was a copy and paste error on my part

You need to remove the comment immediately after the RuleGroup element in the config (In this example the line that includes SYSMON EVENT ID 22 : DNS EVENT LOGGING)

  <EventFiltering>
       <RuleGroup name="" groupRelation="or">
            <!--SYSMON EVENT ID 22 : DNS EVENT LOGGING-->
             <DnsQuery onmatch="exclude">
                   <!--Network noise-->

Sorry that was a copy and paste error on my part as the relevant config extracts I pasted in were mis-interpreted as content tags.. I updated the forum comment but what you need to remove is the comment line that immediately follows the RuleGroup tag (the one that includes SYSMON EVENT ID 22: DNS EVENT LOGGING)

  <EventFiltering>
       <RuleGroup name="" groupRelation="or">
            <!--SYSMON EVENT ID 22 : DNS EVENT LOGGING-->
             <DnsQuery onmatch="exclude">
                   <!--Network noise-->

Regards
