I have installed wazuh and want to configure it so that the event IDs 4800, 4801 are collected. I read about hundred of articles on the web on how to add new event ids. I edited the ossec.conf file on the client (also tried it on the server) to include the event ids.

<localfile>
    <location>Security</location>
    <log_format>eventchannel</log_format>
    <query>Event/System[EventID=4800 or EventID=4801]</query>
</localfile> 

but there are no logs in wazuh. Am i missing something? I can see the events in the event viewer and using wevtutil

PS C:\Windows\system32> wevtutil qe Security /q:"*[System[(EventID=4800 or EventID=4801)]]" /c:5 /rd:true /f:text

I also tried creating custom rules in

nano /var/ossec/ruleset/rules/0210-windows_screenlock_rules.xml

with this content

<group name="windows,">
    <rule id="100100" level="5">
        <decoded_as>json</decoded_as>
        <field name="win.system.eventID">4800</field>
        <description>Windows: Arbeitsstation gesperrt</description>
    </rule>

    <rule id="100101" level="5">
        <decoded_as>json</decoded_as>
        <field name="win.system.eventID">4801</field>
        <description>Windows: Arbeitsstation entsperrt</description>
    </rule>
</group>

The agent is definitely running and is collecting other events but not the ones i configured. I use the pre-configured docker version of wazuh. Thank you in advance.
