Different enterprises will have different regulations on the work scope of this position.
Most of them only involve network equipment within the scope of maintenance, such as data configuration and fault handling of routers, switches and firewalls. There may also be network planning. Basically, just learn ccnp casually.
Some enterprises also let the network operate and maintain servers, even office computers and printers.
Modularization:
The system model can understand the network environment well, and even analyze the complex environment in detail. The core of the system model is used to describe the basic information of equipment. The system model is based on objects and can be extended by inheriting objects.
Automatic discovery:
Use automatic discovery to deal with complex environments. In the process of automatic discovery, the system will visit all monitoring devices in the existing environment to obtain device information.
Standardization:
Because information is collected from different platforms through different protocols, there are many data formats available. Standardize the collected data so that data collected from different systems can be correctly compared.
Agentless data collection:
Rely on agentless data collection to collect data. Communicate with devices through different protocols (including SNMP, SSH, Telnet and WMI) to reduce the impact on the monitored system.
