linux performance counters

After the client is installed, it is intended to monitor the performance counters on the Windows side, primarily to monitor SQL Server-related counters. The online writing is not detailed enough, as the first to learn, or to find more information, the final Test success.The first thing to find is the counter, which can be executed at the command line:[plain] view

transmitted due to an Error.Packets inclued Discarded indicates the number of input Packets to be Discarded, even if no error is found that hinders these Packets from being passed to higher-level protocols. The possible cause for discarding data packets is to release the buffer space.Packets Received Error indicates the number of input Packets, which contain errors that prevent them from being passed to higher-level protocols.Packets Received ED/sec is the speed at which Packets are Received on

Disk bytes/secAVG. Disk Sec/transferAVG. Disk Sec/readAVG. Disk Write/sec The sum of the number of disk reads and writes per second, the very conservative value should be greater than 20MB;Three other parameters, reference value: Network Interface Bytes total/sec Gigabit NIC, reference value: Gigabit NIC, reference value: Output Queue Length Reference value:

Some time ago, I analyzed the performance of the ASP. Net website and used the Windows performance count to monitor the server's Request status. When I use it, the common monitoring points are as follows:1. the Monitored object is Asp.net apps v2.0 .... (Version) The counter uses request/sec, request total, request in application queue to obtain the number of requests per second, the total number of reques

C # traverse all performance counters performancecounter In C #, the type of the performance counter is performancecounter. When using this type, you need to know the categoryname and countername of the counter. For Commonly Used processor, network, and so on, there are still many references for reference query. If it is a counter of a strange point, simply

High-performance and high-concurrency counters in MySQL There are a lot of projects that implement counters at will. For example, when we implement the number of clicks on a website article, we design data tables like: "article_id, article_name, article_content, article_author, article_view ...... Record the page views of this article in article_view. Fraud seems
