Description of drawings
Fig. 1 has described system construction drawing of the present invention;
Embodiment
For those skilled in the art better understands the present invention, further describe method of the present invention below in conjunction with accompanying drawing.
Below to dial up on the telephone by MODEM, the long-range computerized information that obtains, concrete embodiment of the present invention is described, please see Figure 1 system construction drawing of describing of the present invention, whole monitoring system is divided into monitoring client and monitored end, and is middle continuous by telephone network, monitored end operates on the monitored computing machine, collect the information on the computing machine, the order of response monitoring end, and the information of collecting passed to monitoring client.Its realization divides the two large divisions again, is respectively: 1) operate in the monitoring agent program on the monitored computer operating system; 2) hardware monitoring card that is inserted on the monitored computer PCI slot.Above-mentioned monitoring agent program is the one section program that resides in operating system inside, is equivalent to service processes, and it starts after the startup of operating system automatically, after the startup, regularly collects operation system information and also is sent on the monitor card by the monitor card driver downwards.Described monitor card has the Firmware of oneself, and it is independent of the operating system on the monitored computing machine, and the storage chip of a special use is arranged on the monitor card simultaneously, is mainly used to store Firmware on the storage chip and passes through I
2Hardware sensor information that the C bus is collected and the operation system information that hands down by driver by upper strata monitoring agent program.
During operation, monitoring client obtains the information on the monitored computing machine by sending order to monitored end, output of analyzing and processing rear line and demonstration, and wherein the monitoring computers serial ports all links to each other with MODEM with the serial ports of monitored end computer monitoring card.
Above-mentioned is the long-range supervisory system environment that obtains computerized information of the present invention, and method of the present invention is described in detail in detail below, concrete, needs to judge the state of far-end computer before obtaining computerized information, is to determine like this among the present invention:
1, judges whether computing machine connects power supply
Judge by monitoring client,, determine that then far-end computer does not connect power supply, can't obtain any computerized information if under the condition of telephone network connection normal (connection that comprises two MODEM is correct), can't put through far-end computer by dialing.
2, shutdown
Judge by monitor card, according to the 5V power supply signal that only adopts when the computer booting, whether judge computing machine at open state, not start of computing machine the computer mode sign on the monitor card storage chip is not changed to shutdown if having this power supply signal then think.
3, computer operating system be not activated or operating system undesired
As described power supply signal being arranged in above-mentioned steps 2, confirm that then computing machine starts shooting, if undesired, hang-up that operating system is not activated or moves, at this moment the monitoring agent program just there is not startup yet, because monitor card can not receive the information that the monitoring agent program timing transmits, so the computer mode sign is made as operating system and does not open, starts shooting on storage chip.Monitoring client gets access to this information by IPMI standard and custom protocol, does not start or hangs up to user's display operation system, and the operating system real-time information that at this moment gets access to is the information of a preceding operating system when normally moving.
4, the computer operating system operation is normal
Therefore operating system is normal, and the monitoring agent program that operates in the backstage also starts and move normally.The information stores that monitor card transmits the monitoring agent program is to storage chip, and it is normal simultaneously the computer mode sign to be changed to operating system.Monitoring client gets access to this information by IPMI standard and custom protocol, shows to the user.
More than at the long-range state of having determined far-end computer before obtaining computerized information, describing in detail below among the present invention is the long-range computerized information that obtains how, concrete may further comprise the steps:
Step 1: the monitoring agent program on the monitored computing machine of operating in when operating system is normally moved, the real-time operation system information of obtaining, and with on the storage chip that passes under the driver of these operation system information by monitor card on the monitor card; Simultaneously, the monitoring agent program sends heartbeat message by the Firmware of driver timing on monitor card of monitor card, if the Firmware on the monitor card can not receive this heartbeat message in a period of time, will think that operating system is undesired, or be not activated.
In addition, step 2: under Dian the prerequisite, the Firmware on the monitor card passes through I on computers
2The information on each hardware sensor is read in the C bus timing, and described information comprises down one of surface information at least: temperature, voltage, rotation speed of the fan, cabinet switching information etc., and they are stored on the storage chip.
In step 3: the remote monitoring end is by after the MODEM dial-up connection, link to each other with the serial ports on the monitor card on the monitored computing machine, the Firmware by monitor card obtains operating system real-time information, computer mode information and various hardware information from the storage chip on the monitor card.
In view of the above, the back is analyzed and handled to monitoring client to just can and having shown to user's output according to the information that gets access to.
Step below carrying out in the concrete above step 3:
Step 3.1: monitoring client dials up on the telephone by MODEM, directly with monitored computing machine on monitor card on serial ports link to each other, dialing is communicated with, between them in accordance with the Serial/Modem interface specification in ZMODEM agreement and the IPMI standard.
Step 3.2: monitoring client utilizes the form and the self-defining News Category that define in the IPMI standard after setting up good the connection, the storage chip from monitor card obtains operating system real-time information, computer system state information and various hardware information.
Described operating system real-time information comprises one of following information at least: operating system version information, current time in system, network interface card number, network interface card IP address, network interface card subnet mask, cpu busy percentage, memory usage, hard disk I/O flow and active user's progress information etc.
Optimize, also can directly link to each other with monitor card serial ports on the monitored end computing machine among the present invention by the monitoring computers serial ports, the benefit of doing like this is to break down when computing machine, when operating system can't start, the maintainer can be in this locality, by the serial ports monitored computing machine that directly links to each other, obtain operating system real-time information and current system hardware information before the fault from monitored end, analyze these information and draw diagnosis.
Link to each other with serial ports on the monitor card Serial/Modem interface definition that is based on IPMI of the serial ports of this monitoring client.
Information and the hardware information etc. of the present invention by the operating system of storing on the monitor card, but the remote diagnosis computer failure greatly facilitates network operation, and the expense of network operation is greatly reduced.
The above only is a possible embodiments of the present invention, and is non-so promptly limit to interest field of the present invention, and the equivalence that all utilizations instructions of the present invention and accompanying drawing content are done changes, and all reason is with being contained in the claim scope of the present invention.
