pmo metrics

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

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

Disk I/O performance metrics and tuning method bitsCN.com 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 i

This morning the cluster space is full, mobile Ambari Metrics collector Log Directory after the service can not start, the log is as follows:Java.net.ConnectException:Connection refused at Sun.nio.ch.SocketChannelImpl.checkConnect (Native Method) At Sun.nio.ch.SocketChannelImpl.finishConnect (Socketchannelimpl.java:712) at Org.apache.zookeeper.ClientCnxnSocketNIO.doTransport (Clientcnxnsocketnio.java:361) at Org.apache.zookeeper.clientcnxn$sendthread.

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

1. Confusion Matrixis a confusion matrix of two types of problems in which the output uses a different category labelCommonly used metrics to measure classification performance are: The correct rate (Precision), which is equal to tp/(TP+FP), gives the ratio of the true positive example in the sample that is predicted to be a positive example. recall Rate (Recall), which he equals to tp/(TP+FN), gives the true positive example of the predi
