Hi @Reddy Reddy

Could you please provide more clarification on the requirement. You mention "the below tab" but there is no screenshot or image provided.
I believe this is regarding Audit logs on activity on the system, but are you talking about Activity log available in the bottom the client screen or another area of Auditing.

The second question appears to relate to the "system" logs such as TRIMWorkGroupServer..., TRIMEvent..., Render... logs under the location used during install e.g. E:\Micro Focus Content Manager\ServerLocalData\TRIM\Log.
I believe the root path for this can be reset on the server via the registry editor  
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Micro Focus\Content Manager\DataPaths
which contains keys for 
TrimAppData:    E:\Micro Focus Content Manager\ServerData\
TrimLocalAppData:   E:\Micro Focus Content Manager\ServerLocalData\

For the Web Client and ServiceAPI components the log files are set separately in the relevant  web.config file in the log4net section
e.g. 
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="E:\Micro Focus Content Manager\ServiceAPIWorkpath\logs\log-file-" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<datePattern value="yyyyMMdd'.log'" />
<maximumFileSize value="20MB" />
<staticLogFileName value="false" /

Activity log available in the bottom of the client screen, how to get that? I have used it long back, unable to recall that.

Should be an option in the View tab
