Learn linux system monitoring tools 1. Learn linux Make full use of the built-in linux system monitoring tools to quickly and conveniently understand the system performance and other issues, so as to facilitate system analysis and debugging. Learning articles: Every system

servers, Analysis servers, and Hadoop clusters, while the parameters to be monitored are related to the application or tool.There are many great tools for application monitoring, such as Datadog and new Relic.Metrics for application monitoring include: Memory of the JVM process The number of internal threads Disk IO Read/write operations on

and customization of the system may be different, the performance of the system cannot be generalized. Therefore, you can determine whether the system has performance problems by checking the performance expectations of a system. Therefore, we need to first set a baseline data, that is, to calculate the data of each indicator in an acceptable state. You can use

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

There are several reasons for monitoring, including performance, storage status, security, and standard compliance.

orders, and submit order actions that can be defined as transactions, as shown in the following illustration: The number of defined transactions that the system can successfully complete in a unit of time, to a certain extent, reflects the processing capacity of the system, generally measured by transaction success rate, the formula is as follows: Timeout Error Rate: The ratio of a transaction to a total transaction due to a timeout or other error within the system. second, how to monitor ke

shown in the following illustration: The number of defined transactions that a system can successfully complete in a unit of time, which in part reflects the processing power of the system, is generally measured in terms of the success rate of the transaction, and the formula is as follows: Time-out error rate: Mainly refers to the ratio of failures to total transactions due to timeouts or other internal system errors. Second, how to monitor the key indicators? 1. Resource Metrics

Linux performance analysis sar command explanation SAR (system activity Reporter System Activity Report) is currently one of the most comprehensive system performance analysis tools in Linux. It can report system activities from multiple parties, including: file read/write, system call usage, disk I/O, CPU efficiency, memory usage, process activity and IPC-relate
