[C #] SQL Server Service monitor of WinForm (avoid starting the service at startup ), Since I have just started to write a blog and recently become lazy, I have no time to organize many projects in the past. I will first send a small tool that I have previously written. About MS-SQL service Optimization People who have installed MS-SQL servers should know that the system will have 4, 5 more new services

The hardware system of the server should provide the most effective system performance, if the server system performance is suddenly lower than the average should, then the problem may come from the executing process, memory utilization, disk performance.1. System loadIn the Linux operating system, the load of the system can be monitored using the uptime and Vmstat commands. The uptime command returns the c

When jmeter is used for performance testing, nmon can be used for server monitoring. I. nmon description Nmon is divided into toolkit and analysis package (nmonanalyser) The installation of nmon is very simple. Download the corresponding version based on the server version and install it. Ii. nmon listening 1. Real-time Monitoring Run./nmon to start the nmon tool in the nmon installation directory.

Add the SNMP service to the monitored machine as follows:Start → set → Control Panel → add or delete programs → Add/Windows Components (a) → management and monitoring tools → Simple Network Management Protocol (SNMP ).Note: During installation, you must enter the Windows system disk.2. Configure the SNMP Service as follows:Start → run → services. msc → locate the SNMP ser

addition, the workload of generating charts is transferred to the client browser without the dependency of the plug-in. The worst thing is that iOS is okay ...... Highcharts and flot are both very good. The former is relatively more mature, while the latter is an open-source project. The parent company of Highcharts has launched Highstocks, which is also very good, but it is still in the testing stage. js has more than 300 KB. In terms of performance, it is said that flot performance is still e

servers, the parameters of the last few lines can be a good way to reduce the number of time_wait sockets, but for Squid, the effect is not small. This parameter controls the maximum number of time_wait sockets, preventing squid servers from being dragged to death by a large number of time_wait sockets.Tuning is complete, then press to see the effect of it.# Netstat-n | awk '/^tcp/{++y[$NF]} END {for (w in y) Print W, Y[w]} ' established 968Issue 1: How to resolve the request after the e

Ddms is called Dalvik debug monitor server. It provides us with a screenshot of a test device, for example, viewing running threads and heap information, logcat, and broadcast status information for specific processes, simulate telephone calls, receive SMS, virtual geographic coordinates, and other functions. In essence, it interacts with applications on the mobile phone through the ddms tool or IDE debugge

nagios node of the monitoring center, and displays the monitoring result through the web interface. Features of nagios include: Monitors network services such as SMTP, POP3, HTTP, NNTP, and PING) Monitors host resource processor loads, disk space, and so on) Allow users to develop their own plug-ins to check custom projects; By using the "parent host", you can define the layer of the network host to allow

Linux servers. However, these commands require the user to log on to the remote server via SSH. In addition, web-based monitoring tools can also be used to accomplish the same task. Ntop and Darkstat are among the two basic web-based network monitoring tools for Linux systems. In addition to enterprise-class monitoring tools such as Nagios, they provide a number of features that not only
