Weblogic setLogLevel to ERROR with persistent set to 1 is getting reset upon restart of servers

Hi Team,

I have a requirement to have Log Level set to Error at root level for production system.

I have written a WLST code to do so and automate using python so that it could be run across. When I set using persist=1 in setLogLevel(), this the logs showing that log level is Error for all. However when I restart the servers, I am seeing some getting reverted to Warning/Notification.

How to retain the Loglevel to Error.

    cd('/')

    servers=cmo.getServers()

    for server in servers:

        name=server.getName()

        cd('/Servers/'+name+'/Log/'+name)
