Multiplexing function select of the I/O of UNIX and poll.When TCP client handles two inputs simultaneously: standard input and TCP socket.The problem that may run into is that the client blocks that fgets calls in (standard input on) in this case, and server processes are killed.Though server TCP has sent out a FIN correctly for client TCP, client process is just blocking in reading in from the standard input, and it sees this EOF (may cross for a long time) up to read Shi Caineng from socket.At this moment need such ability: if when one or more I/O condition satisfies (for example: input has been ready to be read, and perhaps describing word can be accepted more output), system just is informed to.It is multiplexing that this ability is called as I/O, and function select and poll support that just this I/O is multiplexing.
I/O is multiplexing typically to be used in following network application occasion: when the client handles a plurality of describing word (generally being interactive input and network socket), must use I/O multiplexing; It is possible that a client handles a plurality of sockets simultaneously, need to use I/O multiplexing, but this situation seldom occurs; If a TCP server should be handled the monitoring socket, handle adapter sleeve interface again, it is multiplexing generally also will to use I/O; If a server should be handled TCP, handle UDP again, generally also to use I/O multiplexing; If a server will be handled a plurality of services or a plurality of agreement, generally to use I/O multiplexing.
Multiplexing function can be handled a plurality of incidents by poll, and the incident for needs are handled at first configures.Then, poll successively, if which incident is ready to and need have handled, select just begins to handle this incident.Select function permission process indication kernel is waited for any generation in a plurality of incidents, and only when one or more incidents take place or through ability wakeup process after certain fixed time.
Fig. 1 has represented first scheme of prior art.The daily record that this system utilizes syslog mechanism to send at device log foreground receiving equipment.By the time, import main control module immediately again.After handling by analysis,, deposit database in equipment journal file.Its shortcoming is because time-delay arranged, the operation that system can not real time reaction equipment.
Fig. 2 has represented another scheme of prior art.It is to have utilized the ftp agreement, in specific time, device log is passed to the device log center.User Catalog by appointment comes the forming device journal file, sends the malfunctioning module of a Trap message to network management system simultaneously, and malfunctioning module is transmitted to the device log module with information after receiving Trap.After the device log module received Trap message, the log information in the fetch equipment journal file was analyzed, is deposited equipment journal file in database then.This equipment log management system generally can only be applicable to a kind of device log of equipment.Can't distinguish the kind of device log at all.Therefore be not suitable for the unified management of multiple network equipment.
According to journal management system of integrated network manager of the present invention, the journal file that it has utilized function local0-7 among the syslog and level of security debug to define the receiving equipment daily record.Shown in above-mentioned file, the log information that equipment is sent is respectively in devlog0.1og, the devlog1.log under record/home/zhaohz/nmsdevlog/log catalogue, devlog2.log, the devlog3.log file.Relevant " tail-Of " order, promptly " tail-Of filename " is the sh order that UNIX provides.Its major function is to be that the file content of filename outputs in the standard output with name, and the content of filename file also can output to new content in the standard output when increasing.
