Linux system monitoring and diagnostic tools-lsof usage Overview 1. lsof introduction lsof is a very practical system-level monitoring and diagnostic tool in linux. It means List Open Files. It is easy to remember that it is a combination of "ls + ~It can be used to list the File Information opened by various processes. Remember: "Everything is a file" in linux, including but not limited to pipes, sockets, directories, devices, and so on. Therefore, you can use lsof to obtain information about a

*/for (i = 0; i The ASOC defines three global chain header variables: codec_list, Dai_list, platform_list, all codec, Dai, and platform in the system are connected to these three global lists when registering. The Soc_bind_dai_link function scans each of these three lists, matching them according to the names in card->dai_link[], and assigns the corresponding Codec,dai and platform instances to card->rtd[after the match (Snd_ Soc_pcm_runtime).

In the classification process of QoS, the most important thing is to configure different priorities for different packets, and sort the packets of inbound switches by priority, then, the switch executes the corresponding QoS behavior based on the priority value. The first step of data packet priority sorting is to classify data packets. Classification Rules can use the priority bits of the 802.1p priority field and the ToS (Type of Service) field of t

Linux advanced routing, a policy-based route that is more powerful and flexible than traditional routing, can not only forward paths based on destination addresses but also select routing forwarding paths based on message size, application, or IP source address so that system administrators can easily:1, control the bandwidth of a computer.2, control the bandwidth to a computer3. To help you share your bandwidth fairly4, protect your network from Dos attacks5, protect your Internet from your cus

Client Support Program (for example, dynamicaccess of 3com) perceives the priority of an application when it starts. On each node of the network, the priority is set to 802.1 p on the LAN and iptos on the wan. The Hardware Design of A vswitch must support multiple queues, and services with different priorities are queued separately. For example, a data packet with a higher priority can pass through directly. Normal data packets with a higher priority are cached and transmitted when they are idl
