event handling solutions and concepts can be divided into the following two categories:
Computing-oriented complex event processing solution:
Execute an online algorithm on the event data that enters the system. For example, the average value of the event data that enters the system is calculated continuously.
Detection-oriented complex event handling solution:
Focus on Event combination detection (or event mode detection ). For example, events that match a specific sequence are detected.
A product requires stress testing, so I decided to use the performance tool provided by Windows2003 for system performance monitoring.
If you have sufficient permissions in the test environment, you can easily use a dedicated machine to Execute Performance Tools and remotely monitor the target server, compared to executing monitoring tools on the target server, it does not impose additional resource burden on the target server.
When you execute the "performance" tool and prepare to start the tes

Monitoring servers are a key part of server management..By using appropriate monitoring tools, you can detect server problems, evaluate the results of website content changes, and plan upgrades to facilitate your access to the site. Select an appropriate monitoring tool and method based on the information you need.
You can also monitor the server by checking the logs generated by IIS. These logs extend the logs generated by Mic

New alert Rendering Method
I remember that when I first looked at micromuse's Netcool, I was very impressed with its alarm display method: An alarm-colored diamond base, which is both intuitive and beautiful. Now twaver flex also provides this new alarm rendering method, and there are also various shapes of "base" Options:

Due to the introduction of the concept of building control, the subway station equipment monitoring system is also called the BAS (Building Automation System) system.

When your alarm goes off (Time is up), an Intent registered on it will be broadcast by the system and then automatically start the target program, if it is not running. Registered alarms are retained even if the device is in sleep state (you can choose whether to wake up the device at a given time ). If the alarm is disabled or restarted, the alarm is cleared.
As long as the broadcast onReceive () method is being exe

It is relatively more energy efficient (power-efficient), because the system may combine several similar alarms into one to execute, reducing the number of wake-up times of the device. A bit like a Java timer inside schedule (timertask task, Date Firsttime, long period): When you repeatedly execute a task's plan, The scheduled execution time for each execution of this task changes
response, or WIPS can automatically defend against these attacks.
To generate alarms for illegal wireless access devices, WIDS/IPS usually use ACL (Access Control List) for control. ACL identifies and discovers the MAC address, configuration name, and recently used IP address of the device through wireless access.
Sometimes, we do not want to generate alarms for wireless access devices of neighboring enter

Remote Server Management
After the ipmiutil toolkit is installed on the control end, we can use a series of commands to obtain information about the remote server and set it. Ipmiutil is a toolkit that includes ipmiutil, hwrese, and other tools. They have different purposes, such as hwrese, which can be used to start and shut down servers. You can use ipmiutil -? Or similar commands to view the role of each tool.

3.5 format check
PC-Lint checks the format conflicts between printf and scanf (and their families). For example:Printf ("% + C ",...)A 566 alarm will be generated because the plus sign is only useful for numeric conversion. If there are more than one hundred such combinations, an alarm will be generated. The Compiler usually does not mark these contradictions, other alarms complain about bad formats, which are 557 and 567. We follow the rules set up b
