Abstract
The extended storage method for journal information has two different modes according to criticality, for urgent journal information it can be directly written into non-volatile random access memory, and for general journal information it can be written into a buffer zone in which several journal information can be stored. If the buffer zone is filled up by written journal informations, the contents of the buffer zone can be written into the non-volatile random access memory, after the buffer zone is emptied, the new journal information can be written into it.
Description
Affiliated technical field
The invention belongs to computer network communication field, be specifically related to a kind of method that realizes that on the network switch log information expansion is preserved and safeguarded.
Background technology
Log pattern is mainly used to write down ruuning situation and user's operation behavior of whole system in the network switch, and log information can be shown to on serial ports connection or the terminal with the telnet connection, and this mode is mainly used in debugging and checks system mode; Log information also can store log information server server into, and this mode is used for the ruuning situation of long-term follow system and user's order line operation behavior.
Log information directly is shown on the terminal, advantage is to obtain log information in real time, directly output to the method on the serial ports connecting terminal lessly for the duty ratio of system, shortcoming is that log information can not be preserved, and the output line number also will be subjected to the restriction of user terminal program.Log information stores in the log information server of special outside, advantage is the restriction that does not have the bar number basically, can use specific software conveniently to browse, shortcoming is for an embedded system, system resource is often more limited, because this method all will be packaged into the IP message with all log informations and deliver to special log information server, duty ratio for system is bigger, can influence normal Business Processing, and to require the network between the log information server and the network switch must be available, just can not collect for the log information of having no progeny in the network.In the expansion of some manufacturer realizes, the method that also provides log information to write sdram memory, but the memory headroom that this method can take system to be needed when normally moving, SDRAM information can be lost after the simultaneity factor power down, causes log information not preserve.Simultaneously, in the said method, information run time that the record of log information all being register system, information during for system start-up does not then have record, particularly record special-purpose log information server, must wait system to start basically and finish, could use after the success when ICP/IP protocol stack goes out.
Summary of the invention
The present invention overcomes the deficiency of above-mentioned log information store method, a kind of expansion preservation of log information and the method for handling are provided, can reduce the load of log information recording for system, whether the process that log information is preserved does not rely on network unobstructed, the assurance log information can be preserved after power down, simultaneously, be increased in the system starting process processing to log information.
Technology contents of the present invention: a kind of expansion store method of log information, preserve with two kinds of different modes according to the critical degree of log information, for urgent log information, nonvolatile ram writes direct, for general log information, then write the buffering area that to deposit many log informations, write fullly as buffering area, the content of buffering area is write nonvolatile ram.
Daily record is set writes timer, as timer then, the content of buffering area is write nonvolatile ram.
Technique effect of the present invention: at first select nonvolatile ram (Non-VolatileRandom Access Memory, NVRAM) media of storing as log information, the can be recycled memory space of NVRAM is preserved the log information in nearest period.And whether available, daily record is kept at device interior if not relying on network, guarantees not lose after the log information power down.Secondly, the read or write speed of NVRAM is more much lower than corresponding SDRAM, and and Installed System Memory in order to reduce the read-write number of times, is write NVRAM according to the critical degree of log information with two kinds of diverse ways: for urgent log information on a pci bus, NVRAM writes direct, for general log information, open up the buffering area that can deposit many log informations, use a timer simultaneously, only full or timer just writes NVRAM then the time when buffering.This method can reduce the load of system greatly, and the 3rd, because the initialization of NVRAM is compared in the initialization of whole system early, so, in the process of system start-up, just the log information of log-on message can be write NVRAM, thereby realize monitoring system start-up.
Description of drawings
Fig. 1 is the flow chart that log information writes.
Embodiment
With reference to figure 1, be example with 6800 series of switch of Harbor Network, specify the specific embodiment of the present invention:
Daily record writes opportunity 1: system opens up a free memory, is used for log buffer.When the switch incident takes place, trigger a log information write operation, system can obtain current daily record configuration information.If require to write NVRAM, at first judge the rank of log information, if urgent log information, the NVRAM that writes direct is if general log information judges then whether buffer area can put into log information, if can put into, then information be added in the buffer area.Otherwise, the buffer area content is write NVRAM.Because the capacity limit of NVRAM, the method that can adopt circulation to write, daily record is write just from the beginning to cover after full and is rewritten, because the user is concerned about most basically is the log information of current this section period, so can satisfy user's requirement well.If disposed the log information demonstration or recorded outside log server, then carried out corresponding operation.
For fear of because the buffering area problem that can not write for a long time less than the daily record that causes, daily record writes opportunity 2: create daily record and write timer, when timer then, judge whether the log information preservation is arranged in the log buffer district.If log information is arranged in the buffer area, log information is saved among the NVRAM, empty buffering area after, write new log information.
Claims (2)
1, a kind of expansion store method of log information, it is characterized in that preserving with two kinds of different modes according to the critical degree of log information, for urgent log information, the nonvolatile ram that writes direct for general log information, then writes the buffering area that can deposit many log informations, write full as buffering area, the content of buffering area is write nonvolatile ram, after buffering area empties, write new log information.
2, the expansion store method of log information as claimed in claim 1 is characterized in that being provided with daily record and writes timer, as timer then, the content of buffering area is write nonvolatile ram.
