DFM.log grows up to 3 Giga in 3 Weeks

Question

Hello,
im using cisco works on a windows server system  every 3 or 4 Weeks my backup fails because of  "no disk space".
Searching for the reason i found that DFM.log is too big. After removing  this file the backup runs propperly.
Removing this file needs to stop/start crmdmgtd.
Looking into DFM.log shows many lines of discovery output and i suppose it is the output of a debug command.
in DFM>configuration>logging  logging level configuration is not set.
Month ago i had a problem with DFM and got help from Cisco by an opend Case. i remember that during the work for
this case i was instructed to setup few  commands  like :
dmctl -s DFM put  ICF_TopologgyManager::ICF-TopologgyManager::DebugEnebled TRUE
Maybe i have to reverse  this commands, but not able tu use dmctl commands.

Answer 1

sorry, when i  wrote "i am not able" i wanted to say that i am not familiar with the usage of
the command dmctl. In my last posting i gave only an example of a command.
the full listing of the commands i have done is this:
1.      Enable the Discovery Logs.
Go to NMSROOT/objects/smarts/bin then execute the following command.
       dmctl -s DFM put ICF_TopologyManager::ICF-TopologyManager::DebugEnabled TRUE
       dmctl -s DFM put ICF_TopologyManager::ICF-TopologyManager::LogDiscoveryProgress TRUE
       dmctl -s DFM put ICF_TopologyManager::ICF-TopologyManager::TraceRule TRUE
       dmctl -s DFM1 put ICF_TopologyManager::ICF-TopologyManager::DebugEnabled TRUE
       dmctl -s DFM1 put ICF_TopologyManager::ICF-TopologyManager::LogDiscoveryProgress TRUE
       dmctl -s DFM1 put ICF_TopologyManager::ICF-TopologyManager::TraceRule TRUE
is it possible to set  all to  false  without  stopping the normal work of TopologyManager ?
thank you for your Help
