1. Display Server Status: Db.serverstatus () 2. MongoDB can monitor data through profile to optimize it. Check whether the profile function is currently turned on: Db.getprofilinglevel () returns level, value 0|1|2, meaning: 0 for off, 1 for slow command, 2 for all Open profile function: Db.setprofilinglevel (level,slowms); #level等级. At level 1 o'clock, the slow command defaults to SLOWMS (unit ms)(that is, execution time is greater than slowms for slow

monitoring system that allows network/system administrators to identify and resolve problems before they affect normal business. With the Nagios system, administrators can remotely detect Linux, Windows, switches, routers, and printers within a single window. It can warn of danger and indicate whether there is an exception to the system/server, which can indirectly help you to take rescue measures before t

data needs to be integrated, depending on experience. Swap: Si: the size of the virtual memory (swap) read from the disk per second. If this value is large, the system memory resources are insufficient and frequent memory exchanges are required. So: The size of data written from memory to virtual memory per second, which is the same as that of si. However, when both values are large, the memory resources are insufficient. Io: Bi: The number of blocks received by Block devices (disks) per second

Watch is a very useful command, basically all Linux distributions with this gadget, like a name, watch can help you monitor the results of a command, save you to manually run over and over again. Under Linux, watch is the periodic execution of the next program, and full-screen display of the execution results. You can use him to monitor everything you want. The result of the command changes, such as tail a

For some time, we have been on the internet to show readers how to configure a variety of different performance monitoring tools for Linux and Linux-like operating systems. In this article we will list a series of the most frequently used performance

208412 0 372 0 372 457 47 9 0 10 0 0As you can see from the first result above, the last column (ID) represents the idle time, and we can see that the CPU's idle time is 79%-100% when the baseline is counted. The second result shows that the system is at 100% occupancy and has no idle time. From this comparison, We can determine whether the CPU usage should be optimized.2.0 Installing Monitoring ToolsMost *nix systems have a stack of standard

Monitoring is the core task of cluster management. Monitoring data can be used for scheduling tasks, load balancing, reporting software and hardware faults to administrators, and extensively controlling system usage. The monitoring information must be obtained without affecting the cluster performance. This article wil
