Performance metrics testing for any IPs product must take into account the impact of three factors: network performance, security accuracy, and security efficiency. January 25, 2003 is not a special day, but the day should be remembered by those who design and manage enterprise-class networks. This day, the Ms-sql Slammer virus in Greenwich Mean Time 5:30, making the Internet latency increased by 20% (almost usual 20 times times). By the weekend of

The previous article mentioned the importance of error analysis and setting error metrics. That is to set a real number to evaluate the learning algorithm and measure its performance. With the evaluation and error metrics of the algorithm, one important thing to note is that using an appropriate error metric can sometimes have a very subtle effect on the learning algorithm. This kind of problem is the probl

The last article (Zabbix distributed Server monitoring system installation and deployment (I) records the installation and deployment of the entire Zabbix System, including the Server and client segments, this article mainly describes how to install and configure the custom monitoring metrics of Zabbix. Because I only use some data and other information to monitor mysql The last article (Zabbix distributed Server monitoring system installation and dep

software structure measure methodEarly software metrics were associated with functional decomposition-oriented design methods, mostly based on module metrics.Process-oriented programming, the main factors affecting the quality of software: coupling, cohesion, complexity, modularity and size.Using the software module structure diagram for analysis, can be measured from the following aspects:? Maximum number of data transfers between modules? Average o

the larger the CTR, the greater the pressure on the server. CTR is just a performance reference, and it's important to analyze the impact of clicks. Note that the Click here does not refer to a single click of the mouse, because in a single click, the client may make multiple HTTP requests to the server.8. Resource utilizationRefers to the use of different system resources, such as server CPU utilization, disk utilization, and so on. Resource utilization is the main basis for analyzing system p

For the students with Kafka is very practical.You need to download two Python libraries to local before running this instance: six and Kafka-pythonCat Config_system_metrics.json{"env": {"Site": "Cluster","Component": "Namenode","Metric_prefix": "System"},"Out

a backgroundin a performance test or Linux Server operations, will involve the use of system resources monitoring, in addition to common system commands (such as top,iostat,free, etc.), a more comprehensive resource data monitoring tool is NMON, by running NMON on the server, You can periodically monitor the hardware resources and generate the collected data into a . NMON file. So, the question is, how do you parse the. Nmon file and get the performance data you care about in automated monitorin

a preface In the performance test framework development, you need to process the completed test report of the scene, summarize the performance metrics data that you are following in the report, and then write the report and send the relevant person a message. So, one of the steps is how to capture the data from the test report (e.g.,TPS, Response time, number of concurrent users, etc.). Two problem analysiswhen LR generates a test report, it saves the

centralize logging on CentOS 7 using Logstash and Kibana Centralized logging is useful when trying to identify a problem with a server or application because it allows you to search all logs in a single location. It is also useful because it allows you to identify issues across multiple servers by associating their logs within a specific time frame. This series of tutorials will teach you how to install Logstash and Kibana on CentOS, and then how to add more filters to construct your log data.

Storage Metrics, storagemetrics When a SharePoint site is in use, the content will pass through, which will occupy the content database, increase the management complexity, and even reduce the system response time. You can set site quota to set a warning, so that the Administrator will know that the content of some sites is too large. The next step is to find out where the site occupies space. Obviously, it is unrealistic to manually browse docume

number of vehicles on the highway, the response time is the speed. When vehicles are scarce. When vehicles are very small, the speed is very fast, but the high rate of receipt is correspondingly low; with the increase of the number of highway trucks, the speed is slightly affected, but the high-speed fee received increases rapidly, and as the vehicle continues to increase, the speed becomes more and more slow, and the expressway is getting more and more fast. If the flow of traffic continues to

First look at a diagram:Note: The right image is often used in our workWhat are the Web performance metrics we focus on?1. Page load timeThe time to load from the page to the page onload event firing. In general, the OnLoad trigger represents the CSS,JS directly from the HTML reference, and the picture resource is fully loaded.2. Full page load timeFull page load time refers to the time that the network activity is not available after 2 seconds, start

I think the agile community needs to change the way it evaluates the success of agile teams. The way we collect metrics and get information from these metrics actually hinders us from making the software we use, and that's the most important thing. Pushing individual metrics sometimes leads to focusing too much on others and on team collaboration. This distorts

Before we introduce the disk I/O monitoring commands, we need to understand the metrics for disk I/O performance monitoring, and the performance of some aspects of the disk revealed by each indicator. Indicators for disk I/O performance monitoring mainly include:Indicator 1: Number of I/Os per second (IOPS or TPS)For disks, the continuous read or continuous write of a disk is called a disk I/O, and the IOPS of the disk is the sum of the number of cons

Before introducing the disk I/O monitoring command, we need to understand the disk I/O performance monitoring metrics, as well as the disk performance of each indicator. Disk I/O performance metrics include:Metric 1: I/O per second (iops or TPS)For a disk, the continuous read or write operation of a disk is called a disk I/O. The iops of the disk is the sum of the number of consecutive read operations and w

Enterprise Manager to perform an action when an indicator reaches the baseline of the measure or exceeds the number. Therefore, the management of metrics baselines is critical to the self-monitoring capabilities of the database system. If this metric baseline is set high, then the monitoring will not work. The database may have crashed when the system was alerted. If this metric baseline is set relatively low, then the database is frequently reported
