Description

Data acquisition method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a data acquisition method and apparatus.

Background

With the continuous expansion of wireless networks, normal network operation is inseparable from normal work and life of people, and in a huge network body, a server becomes a critical healthy node. If an OMC (Operations & Maintenance Center) server crashes or runs abnormally, a catastrophic result is often brought to the management of a radio network controller and a base station; in addition, the low operation efficiency of the server brings difficulty and trouble to normal application, and finally affects the normal operation of the network. Therefore, maintenance personnel are required to clarify hardware data of the server in real time, such as hardware basic data and state information, so as to eliminate hidden dangers in time, solve problems in advance and ensure normal operation of the server and the network.

Due to the numerous and remote servers, remote access by operation and maintenance personnel is often required. At present, operation and maintenance personnel mostly acquire data through an SNMP (Simple Network Management Protocol) proxy mode or a TELNET access mode to perform operation, maintenance and Management.

In the SNMP agent mode, the SNMP agent presents the management data by variables. The SNMP management system retrieves the required hardware data from the equipment with the SNMP agent through GET, GETNEXT and GETBLK protocol commands; alternatively, the server SNMP agent uses TRAP or INFORM commands to transfer relevant hardware data without being queried.

The TELNET access mode mainly comprises the following 4 processes: (1) establishing a connection with a remote host locally, which is actually establishing a TCP connection, the user must know the IP address or domain name of the remote host; (2) transmitting the user name and password input on the local Terminal and any command or character input later to the remote host in NVT (network Virtual Terminal) format to collect corresponding hardware data and the like, wherein the process is actually to send an IP data packet from the local host to the remote host; (3) converting hardware data in NVT format output by the remote host into format accepted locally and sending the format back to the local terminal, wherein the format comprises input command playback and command execution results; (4) finally, the local terminal cancels the connection of the remote host, and the process is to cancel a TCP connection.

However, there is a problem in either of the above two methods. One problem is that both of the two modes can only collect partial hardware data, but cannot obtain complete hardware data, the returned result is limited, and the indexes which are crucial to collecting hardware equipment information may not be collected, for example, the TELNET remote login access mode cannot collect the CPU temperature of the hardware, the SNMP agent mode cannot complete a single query command or return of multiple data information of a data collection command, and the like. Another problem is that in the SNMP agent approach, if the SNMP service of the server is not opened, the manager cannot perform query maintenance; however, if the SNMP services are running all the time and many times these SNMP services are unnecessary, it will bring extra overhead to the server.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Example one

Referring to fig. 1, a flowchart illustrating steps of a data acquisition method according to a first embodiment of the present invention is shown.

The data acquisition method of the embodiment comprises the following steps:

step S102: and determining the access level of the hardware data to be acquired according to the hardware data acquisition request.

Wherein, the access level of the hardware data comprises: SNMP access, TELNET access, and both SNMP and TELNET access.

When the access level is SNMP access, the hardware data can be collected only through SNMP service; when the access level is TELNET access, the hardware data can be acquired only through TELNET service; when the access level is both SNMP and TELNET accessible, the hardware data can be acquired through SNMP service or TELNET service.

Step S104: and if the access level of the hardware data to be collected is SNMP access, performing steps S106-S110.

Step S106: logging in the equipment where the hardware data to be acquired is located through the TELNET service, and starting the SNMP service on the equipment through the TELNET service.

In this embodiment, the SNMP on the device where the hardware data to be acquired is set to be in the off state when not needed, so as to save the overhead and the loss of the device. The start and the stop of the SNMP service are controlled by the TELNET service, so when the hardware data can only be collected by the SNMP service, the hardware data still can be logged in through the TELNET service connection, then the SNMP service is started by the TELNET service, and the hardware data is collected by the SNMP service.

Step S108: and the SNMP service collects and returns the hardware data to be collected.

The hardware data collection of the SNMP service can be implemented by referring to a related process, for example, sending a SET (value) command after mapping through an MIB (management information database) variable, and the like, which is not described herein again.

Step S110: and after the SNMP service returns the hardware data to be acquired, the SNMP service on the equipment is closed through the TELNET service.

After the hardware data is collected, the SNMP service can be temporarily stopped so as to save equipment overhead and loss. In addition, some hidden vulnerabilities may exist on the network, and running the SNMP service all the time may become a target for running a vulnerability attack, which causes a potential safety hazard of the server. And when the SNMP service is not needed, the SNMP service is closed, so that the attacks and hidden dangers can be effectively avoided.

In this embodiment, all the hardware data that can be collected have an access level, and by means of the access level, which manner the hardware data can be collected is identified. When hardware data acquisition is needed, different service acquisition can be adopted according to the access level. Particularly, when the access level of the hardware data is SNMP access, firstly, equipment where the hardware data to be acquired is located is logged and connected through a TELNET service, then an SNMP service on the equipment is started, further, hardware data acquisition is carried out through the SNMP service, and the SNMP service on the equipment is still closed through the TELNET service after the hardware data are acquired. With the present embodiment, hardware data can be collected at whatever access level. More importantly, the SNMP service is controlled through the TELNET service, so that on one hand, the SNMP service can be conveniently and timely opened when the SNMP service is required to collect data; on the other hand, when the SNMP service is not needed, the SNMP service can be closed, so that the expenditure caused by the SNMP service is saved; on the other hand, vulnerability attack can be effectively avoided, and equipment safety is guaranteed.

Example two

Referring to fig. 2, a flowchart illustrating steps of a data acquisition method according to a second embodiment of the present invention is shown.

The data acquisition method of the embodiment comprises the following steps:

step S202: and setting the access level of the hardware data according to whether the hardware data is accessed by SNMP service and/or TELNET service.

That is, the access level of the hardware data is set according to whether the hardware data can be collected by which service, and the set access level includes: SNMP access, TELNET access, SNMP and TELNET are all accessible.

Step S204: determining the access level of the hardware data to be acquired according to the hardware data acquisition request, and if the access level is SNMP access, executing the step S206; if the TELNET access is performed, step S214 is executed; if both SNMP and TELNET are accessible, step S216 is executed.

Step S206: carrying out management information database (MIB) variable mapping of the SNMP service according to hardware data to be collected; sending a value taking command to the SNMP service according to the result of the MIB variable mapping; and determining that the SNMP service is closed according to a return result of the value taking command.

When the SNMP service management terminal determines that the SNMP service is needed to collect hardware data, the related instruction of the SNMP service is generated and sent to the SNMP service terminal provided with the SNMP agent so as to determine whether the SNMP service on the service terminal is in a closed state or not, and if the SNMP service is in an operating state currently, the SNMP service can be directly used for collecting data; in general, when the SNMP service is in a closed state, subsequent steps are required to be executed, the TELNET service is used to start the SNMP service, and then data is acquired.

Step S208: logging in the equipment where the hardware data to be acquired is located through the TELNET service, and starting the SNMP service on the equipment through the TELNET service.

Step S210: and the SNMP service started by the TELNET service collects and returns the hardware data to be collected.

The method comprises the following steps: MIB (management information database) variable mapping of SNMP service is carried out according to hardware data to be collected; sending a value taking command to the SNMP service according to the result of the MIB variable mapping; judging whether the SNMP service is operated; if the hardware data is operated, acquiring the hardware data to be acquired according to the value taking command and returning the hardware data; if not, operating the SNMP service through the TELNET service; and acquiring hardware data to be acquired according to the value-taking command and returning the hardware data.

Step S212: after the SNMP service returns the hardware data to be collected, the SNMP service on the device is turned off through the TELNET service, and step S222 is executed.

Step S214: if the access level of the hardware data to be acquired is TELNET access, the device where the hardware data to be acquired is located is logged in through the TELNET service, the hardware data to be acquired is acquired and returned by the TELNET service, and step S222 is executed.

The specific process of acquiring hardware data through the TELNET service may be implemented with reference to a related flow, and is not described herein again.

Step S216: if the access level of the hardware data to be acquired is both SNMP and TELNET accessible, logging in the equipment where the hardware data to be acquired is located through TELNET service, and judging whether an SNMP service request for acquiring the hardware data to be acquired is received; if not, go to step S218; if yes, go to step S220.

Step S218: if the SNMP service request for acquiring the hardware data to be acquired is not received, the TELNET service acquires and returns the hardware data to be acquired, and step S222 is executed.

Step S220: receiving an SNMP service request for acquiring hardware data to be acquired, starting an SNMP service on the device through the TELNET service, acquiring and returning the hardware data to be acquired by the SNMP service, and after the SNMP service returns the hardware data to be acquired, closing the SNMP service on the device through the TELNET service, and executing step S222.

The step of collecting and returning the hardware data to be collected by the SNMP service comprises the following steps: MIB (management information database) variable mapping of SNMP service is carried out according to hardware data to be collected; sending a value taking command to the SNMP service according to the result of the MIB variable mapping; judging whether the SNMP service is operated; if the hardware data is operated, acquiring the hardware data to be acquired according to the value taking command and returning the hardware data; if not, operating the SNMP service through the TELNET service; and acquiring hardware data to be acquired according to the value-taking command and returning the hardware data.

Step S222: MIB variable mapping is carried out on hardware data acquired by SNMP service, and the hardware data subjected to MIB variable mapping is converted into hardware data conforming to a set format; and/or performing character string extraction processing on the hardware data acquired by the TELNET service, and converting the hardware data subjected to the character string extraction processing into hardware data conforming to a set format.

The collected hardware data needs to be processed into a uniform format for subsequent processing, and the uniform format can be preset by those skilled in the art according to actual requirements.

In one hardware data acquisition, it is possible to acquire data using only one service, or it is possible to acquire data using two services. If only one service is used, only the data collected by the service can be processed, if only the SNMP service is used, MIB variable mapping can be carried out on the hardware data collected by the SNMP service, and the hardware data subjected to MIB variable mapping is converted into the hardware data conforming to the set format; if only the TELNET service is used, the hardware data acquired by the TELNET service can be subjected to character string extraction processing, and the hardware data subjected to the character string extraction processing is converted into hardware data conforming to a set format. When both the TELNET service and the SNMP service are used, MIB variable mapping is required to be performed on hardware data acquired by the SNMP service, and the hardware data subjected to MIB variable mapping is converted into hardware data conforming to a set format; it is also necessary to perform a string extraction process (e.g., remove redundant content in a string, extract required string content, etc.) on the hardware data acquired by the TELNET service, and convert the hardware data after the string extraction process into hardware data conforming to a set format.

With the embodiment, different services are used for acquisition and processing according to the access level of the hardware data to be acquired. But whatever level the hardware data belongs to, its acquisition needs to be logged and controlled by the TELNET service. According to the embodiment, by means of remote cross complementary data acquisition of SNMP and TELNET, effective access of a management end and a service end can be opened in a cross mode, basic data and state information of equipment are acquired to the maximum extent, and data are displayed to maintainers in a step-level mode in detail in a staged mode, so that the automation rate of OMC remote maintenance and the accuracy of problem diagnosis are improved, time is effectively saved, maintenance cost is reduced, working efficiency is improved, and network safety is guaranteed.

EXAMPLE III

Referring to fig. 3, a flowchart of steps of a data acquisition method according to a third embodiment of the present invention is shown.

The data acquisition method of the embodiment comprises the following steps:

step S302: an access level of the hardware data is determined.

The hardware data which can be collected is classified and graded, and the access level is divided according to whether the hardware data can be accessed by TELNET service or not and whether the hardware data can be accessed by SNMP service or not, so that the subsequent inquiry is facilitated. After classification and classification, the access level of the hardware data comprises: accessible only by SNMP services, accessible only by TELNET services, accessible by SNMP services or TELNET.

It should be noted that for hardware data without SNMP level (i.e. hardware data accessible only by TELNET service), the SNMP service will not be started.

Step S304: receiving a hardware data acquisition request, judging whether the hardware data to be acquired can be acquired by TELNET service according to the access level of the hardware data to be acquired, and executing step S306 if the hardware data to be acquired can not be acquired by the TELNET service; if the TELNET service can be acquired, step S332 is executed.

Step S306: and carrying out MIB variable mapping of the SNMP service according to the hardware data to be collected.

Step S308: and sending a value taking command of the SNMP service to the equipment where the hardware data to be acquired is located.

Step S310: judging whether the SNMP service is operated currently, if so, executing step S312; if not, go to step S320.

Step S312: if the SNMP service is currently operated, the server-side equipment receives the value-taking command of the SNMP service, processes the value-taking command of the SNMP service, and returns the processing result carried in the SNMP message.

If the SNMP service is operated, the SNMP service is processed according to a value-taking command such as an SET command, corresponding hardware data is collected, and then the collected hardware data is carried in an SNMP message and returned to a request terminal requesting the hardware data.

Step S314: MIB variable processing is mapped to the hardware data in the returned SNMP message, and step S316 is executed.

Step S316: and converting the processed hardware data into hardware data conforming to a set format, and returning data statistics.

Step S318: and requesting the TELNET service to close the SNMP service on the device where the collected hardware data is located.

Step S320: and displaying a data acquisition result and finishing the data acquisition process.

It should be noted that, the execution of step S318 and step S320 may not be in a sequential order, or may be executed in parallel.

Step S322: and if the SNMP service is not operated currently, requesting the TELNET service to open the SNMP service on the equipment where the hardware data to be acquired is located.

Step S324: judging whether a request of the SNMP service is received, if not, executing the step S326; if yes, go to step S330.

Step S326: and sending a value taking command of the TELNET service to the server side equipment where the hardware data is located.

Step S328: the server device processes the value taking command of the TELNET service, returns a message carrying a processing result, and directly executes step S320 after step S316.

Namely, hardware data are collected according to the value taking command of the TELNET service, and the collected hardware data are carried in the return message and returned.

Step S330: if the request of the SNMP service is received, the TELNET service remotely starts the SNMP service, and the step S308 is skipped to and executed.

Step S332: if the hardware data to be acquired can be acquired by the TELNET service, the TELNET service is used to log in the server device where the hardware data to be acquired is located, and step S324 is skipped to start execution.

In this embodiment, the data acquisition and access flow of the TELNET service may log in, send a command, receive a return message, and send the result to a corresponding processing device, such as a data acquisition center, according to the original process. Meanwhile, the TELNET service in this embodiment also needs to remotely start the SNMP service and remotely close the SNMP service when necessary.

The data acquisition and access process of the SNMP service in this embodiment needs to be controlled by the TELNET service in the whole process, and after the access level of the hardware data to be acquired is determined, the hardware data of the SNMP service access level can SET and acquire the hardware data of the server through SET and GET commands of the SNMP service. However, in many cases, the SNMP service is turned off, and for safer management, the SNMP service is preferably turned off, where the SNMP access is suspended, and requests the TELNET service to remotely start the SNMP service, and then the SET and GET command operations are resumed, and after the operations are successful, the data is pushed to the corresponding processing device, such as the data collection center, and the SNMP service is turned off. And if the SNMP service does not exist, stopping the processing process of the SNMP service, and only carrying out TELNET access.

For any kind of hardware data collected by the service, data statistics, summary display, storage and other processing are required. And after the two service acquisition processes reach the management terminal, processing the acquired hardware data, wherein an MIB table is mapped to an SNMP message, a character string is processed to a TELNET return message, and the MIB table and the TELNET return message are uniformly processed into the same form and then displayed and stored.

Through this embodiment, (1) parallel collection, raise the efficiency have been realized. The acquisition is carried out in parallel by two modes of SNMP service and TELNET service, so that the efficiency can be improved by two times when multiple tasks are originally inquired and acquired in a single mode, and the cost and the time can be greatly reduced for the inquiry, acquisition and maintenance of a centralized server; (2) the data are complementary, and the information is comprehensive. The data returned by the TELNET service is hashed and contains more redundant information; the data returned by the SNMP service is targeted, for example, the TELNET service can access the general situation of a CPU, and the CPUU temperature can be deeply inquired through the SNMP service, so that the most comprehensive hardware state information can be provided to the operation and maintenance personnel to the maximum extent; (3) and cross control is performed, so that the comprehensive control of the SNMP service is ensured, and the safety of the SNMP service is improved. In the embodiment, for hardware data acquired by the SNMP service, the TELNET service remotely opens the SNMP service before starting to access, so that normal access of the SNMP service is ensured. The phenomenon that the SNMP service can not be interacted by singly using the SNMP service is avoided under the condition that the SNMP service is not opened. After the access is finished, the TELNET service closes the SNMP service, so that unnecessary expenditure of a service end where hardware data are located is saved, and risks caused by the SNMP service are avoided.
