Preliminary study on Elasticsearch polymerization--metrics

Elasticsearch is an open-source framework that provides search and correlation sequencing, while also supporting complex statistical-aggregation of stored documents. The Kubana icons are drawn based on aggregations. For more information, please refer to the Elasticsearch+logstash+kibana tutorial ObjectiveThe aggregations in ES are divided into two main categories: the metrics metric and the bucket bucket, and the

Disk I/O performance metrics and tuning methods

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

Implementing Oracle Self-monitoring with metrics baseline technology

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

Review of Software Metrics

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

Web performance testing Basic performance metrics

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

Python's posture to analyze nmon and get performance metrics data is like this

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

Python implementation parse LR analyse result and generate summary performance metrics Data Report

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

Software program Performance metrics

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
