In the performance testing process, it is of great significance to monitor host resources. On the one hand, during the test, you can determine whether the pressurization is successful and whether the system can withstand the current pressure to ensure system security. On the other hand, after the test, you can sort the monitoring data, it can provide data support for performance analysis, problem discovery, and bottleneck search. This article will int

tools capture separate packages on the link, analyze their content, and display decoded content or packet-level statistics. These tools monitor and manage the network at the lowest level, as well as the most granular monitoring, at the expense of the process of affecting network I/O and analysis.Dhcpdump: A command-line DHCP traffic sniffing tool that captures DHCP request/reply traffic and displays decode

Most of the code is currently in Perl and the information collected is based on Nagios, but the entire suite is designed to be extended to other monitoring frameworks and other languages. It may be your own remote agent, a specific data store, or another user interface.The OPM project began in 2012 and has been running for months

benefits;The data processing strategy of middleware will make your basic service more stable and efficient;Storage-side　　The biggest problem we encountered when using hbase was that it caused some IO storms after the data was deleted, and there was a situation where the Phoenix0.4.0 ran out of CPU (0.4.2 has been resolved). Our solution for these situations is to have the table split in time. In other words, a table is rolling like a log file by time, and the benefit is that deleting old data w
