Monitoring Application Analysis Based on. NET Technology (2)

In the previous article. in the Application Analysis of net technology monitoring (I), I talked about the analysis of data collection and communication technology. In fact, there is also a very important part, that is how to effectively deploy on a large number of servers. Free Shipping

Because the monitored network has multiple subnets, select a gateway server of the subnet as the gateway server for managing all machines in its range during deployment. This method is easy to deploy and convenient for unified management, but has high requirements on gateway servers. Another mode is to install a service for each machine and then deliver the service to the monitoring center through the gateway server. In this way, the gateway server serves only one intermediate function because it is only responsible for data communication, therefore, the pressure is relatively small. This method is complicated when security and management need to be centralized and unified due to scattered deployment.

3 , Network Architecture

System network connectivity adopts cross-region networking:

The central network is composed of database servers, email servers,WebServer and SMS sender.

The network in each region is composed of a proxy server and monitored server devices.

The proxy server is the local monitoring proxy server of the monitoring center and also serves as the monitoring proxy database server.

Various server devices must be enabledWMIServices and135,445Port.

4 , System Update and upgrade

Because servers are distributed in different regions, the system needs to implement automatic update. Once a new version is released, the monitoring party broadcasts the upgrade message. The proxy server downloads the new version.ProgramThe server in the subnet is then downloaded from the proxy server. After receiving the message, the automatic update module of the proxy server downloads the program from the publisher and closes the system process. After the update is complete, the automatic update system restarts the data communication service.

System update process

We adopt the second deployment architecture. So far, after more than a year of operation, the system has effectively monitored the software and hardware on the website server, especially the application systems for website services, once the system of the website encounters an exception, the O & M personnel can automatically receive an alert text message, enabling automatic management of website O & M monitoring.
