jmx metrics

Server monitoring?? In addition to deploying WebApp, you need to monitor the service's exception information and server performance metrics when building the server, and notify the administrator of any exceptions.?? The server was built using Linux+nginx-1.9.15+tomcat7+java.?? Write scripts to detect error logs and server performance metrics, and use cloud monitoring to upload alarms to cloud accounts once

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

LoadRunner)User-defined performance metrics – custom performance metrics supported by LoadRunner, such as: Transaction Response time, Transaction Per Second Passed, Failed.One.%processor time:cpu Average utilization%user Time: User-state CPU average utilization% Privileged Time: Kernel mindset CPU Average utilizationProcessor Queue Length: Number of threads in the processor queueContext switches per Second

If all of the internal technical factors are left behind, we only look at the performance metrics of the application, so generally speaking, the performance of the program can be measured in the following ways. N Response Time: The time the system responds to user behavior or events. The shorter the response time, the better performance, so we should try to use asynchronous processing in the system design process, so that users can receive receipts as

indicator that can display system-wide delay type errors. It is the sum of memory\\pages input/sec and memory\\pages output/sec . is calculated using the number of pages, so that it can be compared with other page counts, such as memory\\page faults/sec , without having to do the conversion , which includes the file system cache to satisfy the error ( typically requested by the application The page is retrieved in a non-cached mapped memory file. Recommended indicatorsThis value should not exc

Linux CPU metrics Linux provides a wealth of commands to monitor CPU-related data, such as top and vmstat. Top is a dynamic display process, that is, you can press the key to continuously refresh the current status. If you execute this command on the foreground, it will exclusively occupy the foreground until the user terminates the program. More accurately, the top command provides real-time monitoring of the status of the system processor, it displa

[Method] outputs the running metrics of workflow to target, and workflowtarget Take the output workflow start time as an example: First, create the workflow-level variable $ test (datetype: date/time) in workflow) Next, double-click the link after Start and assign starttime to the newly defined wk variable $ test. Return to the Designer and add the mapping-level variable $ test (datetype: date/time) to the mapping) Return to Workflow Manage

, it is certainly uncertain.Such a portal system, because of the user rights, so not as Jackie said most of the static page. But as long as it is a multi-server cluster, we can calculate the load capacity of multiple machine clusters through the test results of 1 machines, with the additional consideration of load balancing and routing pressure, such as bandwidth, speed, latency, etc. But if all the changes in 1 machines, then we can only do some of the indicators on the calculation, can be easi

."Intermediate response time" is the median response time for a period of time, 50% response time, and half of the server response time is below that value and the other half is above that value."90% response Time" 90% of transaction response time is smaller than this value over time. Response to the overall response speed, and the 10% timeout rate above that value. is one of the important indicators used to assess system capacity.Minimum response time for the Min. reflects the fastest processin
