hbase performance monitoring

For system and network administrators, it is a heavy task to monitor and debug the performance of Linux systems on a daily basis. After 5 years working as an administrator in the IT field as a Linux system, I gradually realized how difficult it was to monitor and keep the system up and running. For this reason, we have written a list of the 18 most commonly used command-line tools that will help each Linux/unix system administrator work. These command

As you learned in part 1th of this series (three articles), monitoring the availability and performance of Java applications and dependencies in production is critical to ensuring problem detection and accelerating problem diagnosis and repair. Source-code-level inserts for classes that need to be monitored have the advantages that are discussed in part 1th, but this method is often not available or impract

exception through the atop command view.Atop logEach time-point sampling page is combined to form a atop log file that we can use to view the log file using the "atop-r XXX" command. So what is the format for saving atop log files?For how to save the atop log file, we can do this: Save a atop log file every day, which records the information of the day Log files are named "ATOP_YYYYMMDD" Set the log expiration period, automatically delete the log file before a period of time

Label:The IO performance of SQL Server is affected by the IO latency of the physical disk and the IO operations performed internally by SQL Server. When monitoring disk performance, the primary measure (metric) is IO latency, which is the time delay in creating an IO request from application to disk to complete the IO request. SQL Server is prone to

In parts 1th and 2nd of this series (a total of three articles), I introduced the techniques and patterns for monitoring Java applications, in which I focused on the JVM and application classes. In this final installment, I'll introduce tips for collecting performance and availability data from application dependencies, such as the underlying operating system, the network, or the application's back-end data

Then we manage the server when the WINDOSW system is more intuitive, how much CPU use, how much bandwidth memory used, etc. as long as in the Remote Desktop Task Manager at a glance. But in the Linux environment is not so easy, especially the server or VPS running is a large web site, if you can not find the server performance consumption in time, it is likely to lead to the site in the peak visit, there is no known card death. So, eagle, then. This a
