uptime sla

The Linux uptime command is primarily used to get the host running time and query the Linux system load and other information. The uptime command used to show only how long the system was running. Now, you can show how long the system has been running, and the display of the information is: now time, how long the system has been running, how many users are currently logged in, the system's average load in t

This article describes some useful and common Linux or UNIX commands that are commonly used by Linux system administrators. Instead of a complete list, this article briefly lists the commands that come in handy when needed, starting with an example of how to use these commands.1.uptime commandIn Linux, the uptime command shows how long your system has been running and how many users are currently logged on,

This article describes in detail multiple methods for obtaining Timestamp and time difference from nodejs, which is helpful for the use of nodejs at ordinary times. Let's take a look at it. There are many methods to obtain the timestamp in Nodejs, such: 1. new Date (). getTime () 2. Date. now () 3. process. uptime () 4. process. hrtime () You can use these methods to obtain a timestamp. What are the differences between these methods? New Date (). get

1. the concept of average load in Linux sometimes finds that the system response is slow, but we cannot find the cause. in this case, we need to check the average load, check whether a large number of processes are waiting in the queue. The average number of processes in the running queue within a specific interval can reflect the system's degree of busyness. Therefore, we usually check the system load as soon as our website or system slows down, that is, the average CPU load. 2. how can I view
