Precautions for using win32_perfformatteddata_perfdisk_logicaldisk Note the following before using win32_perfformatteddata_perfdisk_logicaldisk: (1) You cannot use obw.miservice. execquery to execu

time may be caused by a single (or multiple) overloaded processor, many other tools can be used to narrow the cause of the load. to delve deeper into processor usage, the 3 tools described below can provide many different understandings of CPU utilization: Vmstat, Iostat, and top. Each of these tools focuses on different aspects of system monitoring, but can get a different view of the current usage of the processor. In particular, the next step i

Set up performance monitoring Spotlight in Centos The company wants to perform a stress test with a Linux server and Centos6.5. To intuitively display the system performance and better analyze the server, we need to build a monitoring system. Let's go straight to the topic. First, a Linux Server: Centos6.5 Second, inst

For systems running on-line, current database performance monitoring typically monitors the following points:(1) Whether there is obstruction (Blocking);(2) whether there is waiting (waiting), blocking is the lock (locks) waiting;(3) Whether the running time is too long (long running);(4) Whether there is a deadlock (Deadlock);Sys.dm_exec_query_stats and so on, and so on some statistical information, usuall

Full-featured built-in analyzer such as jconsole and visualvm sometimes cost more than they cost performance-especially in systems running on production software. Therefore, in the 2nd articles focusing on Java performance monitoring, I will introduce five command line analysis tools, allowing developers to focus only on one aspect of the running Java Process. JD

two concepts, swapping also translated into Exchange, In the operating system refers to the full exchange of a program to the hard disk to free up memory for the new program to use, and paging only the part of the Exchange Program (page) is a two different concepts. Pure swapping is hard to see in modern operating systems, because it is time-consuming and laborious and unnecessary for the entire program to be switched to a hard disk, and the modern operating system is basically paging or paging

Linux system performance and use of activity monitoring tool-Sysstat Sysstat is indeed a convenient tool for monitoring system resources, system performance, and usage activities. The sysstat package is used more or less in our daily basic tools. It also provides a tool that can use cron for scheduled operation to coll

Analyzer or packet sniffer program-to capture or filter TCP/IP packets received or transferred from a specific interface on the network. It also saves the captured package to a folder. Tcpdump can be used on all major Linux distributions.5.netstat--Network StatisticsNetstat is a command-line tool for monitoring incoming and outgoing network packet information and interface information statistics. It is useful for system administrators to use it to mo

of setting method and level, one is by adding –slowms boot parameter configuration. The second is to invoke Db.setprofilinglevel with the second argument: Db.setprofilinglevel (level, SLOWMS) 2. Query Profiling Records Unlike MySQL's slow query log, the MongoDB profile record is directly present in the system DB, and the record location is System.profile, so we'll just have to check the collection record to get our profile records. List profile records with execution times longer

Label:Original: SQL Server Automation Operations series-Monitoring Performance metrics script (Power Shell)Requirements DescriptionGenerally in the production environment, sometimes need to automatically detect the status of the indicator value, if there is an exception, need early warning, such as e-mail notification, this article is introduced if the power shell to achieve status value monitoringRange of

According to the company's new project requirements, a traffic and Performance Monitoring System server was configured with Cacti in RHEL5.4 over the past two days. The installation process has been recorded for reference by myself and other friends. Cacti is a set of graphic analysis tools for network traffic monitoring developed based on PHP, MySQL, SNMP, and R

A monitor in front of the monitoring is defective, this article uses jmeter4.0+ version, using plug-in Sshmon Samples collector to do resource monitoring1. Download the plugin: Plugins-manager.jar, then put it in the Lib/ext directory and restart the jmeter.2. Open options--> Plugins Manager, tick Sshmon Samples Collector in the "Available Plugins" column and click Apply Change and Restart Jmeter3. The use of this plugin, the need to point the Linux S

We know that system optimization is a complex, tedious, and long-term task. the following subsystems are usually monitored: CPUMemoryIONetwork The following is a commonly used monitoring tool. Linux includes many subsystems (including CPU, Memory, IO, and Network). We know that system optimization is a complex, tedious, and long-term task. normally, the following subsystems are monitored: CPUMemoryIO Network The following are common

this point, you can open a new terminal.If the terminal does not generate some data flow, then it will not produce so many packets.For example, when using tcpdump to view the packet, it is actually in the traffic generated data flow, so there is a packet generation, this is an internal loop.If this terminal does not produce any data and does not produce any information, then it does not have any packets. The data packet is generated, and the screen (the paused interface) naturally has the data.

The topas command of AIX performance monitoring parses the most comprehensive dynamics of the operating system in detail, and the convenient performance view is the topas command. The topas output is used as an example below, briefly describe the performance monitoring of th
