transparent.gif Handling Process

From the current information, the CPU high because of that there are too many SNMP request to NE40E, you added too many nodes on NMS. Please delete some monitoring task on NMS. If can’t, please filter those IP address on NE40E to reduce the CPU usage. The details are as follows.

1.    When CPU usage is high, the CMF and IFM process is high. Those two process high means that there are too many NMS tasks collecting interfaces information and make CPU high.

2.  From the process, there are many MTif script operation, it means there are too many NMS tasks collecting interfaces information.
