- Bottlenecks
- one device uses noticeably more CPU time than the others
- these devices tend to become bottlenecks:
- CPU,
- memory,
- network card,
- disk controllers,
- network media
- Windows NT Performance Monitor
- view operations in both real time and recorded time for: processors, HDD, memory, network utilization, network as a whole
- can record the performance data
- send an alert to the network manager
- run utility that can adjust the system back into acceptable ranges
- establish a baseline of system management
- Simple Network Management Protocol (SNMP) - in a SNMP environment, programs called agents are loaded onto each managed device. The agents monitor network traffic and behaviour in these key network components in order to gather statistical data. This data is stored in a management information base (MIB)
- SNMP components include: hubs, servers, interface cards, routers and bridges
- The MIB collects data and the management program
- presents the information in the form of graphs or charts AND/OR
- sends the information to database program for analysis
Total System Management
- Microsoft System Management Server (SMS)
- centralized administration of computers in a WAN
- Inventory Management - collects and maintains an inventory of hardware and software for each computer and stored in a SQL server database, info. like RAM, CPU, HDD size...
- Shared Application Management - shared application can also distributed to a server for client's access
- Software Distribution
- SMS can install and configure new software or upgrade previously installed software
- Also, it can run commands on the client such as virus scans
- Remote Control and Network Monitor - provide help desk and diagnostics utilities to control remote client directly and access to remote client
