In this scenario, I constructed a useful example without creating an index on the Sales_order table. As a result, monitoring will reveal more sequential scans (in database terms for table scans), which is a inefficient mechanism for retrieving data because it reads each row in the table. Sequential tuple reads-the number of rows that are read using sequential scans. There is a big difference between rows and tuples, but it doesn't matter here. To unde

Introduction to Linux Monitoring platformZabbix Monitoring IntroductionZabbix He is also C/s architecture, there is a server and then go to the client to catch data, grasping data in the client must have a service to start, the service is to replicate the data collected, this data can be actively escalated to the service side, can also let the service side to connect the customer to capture this data, which
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 article describes how to use SNMP plus
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 database. At the end of the article I'll discuss
