The collection performance data device 103 receives the command sent by the calling system 101 through the unified command interface, and returns the collected performance data to the calling system 101 through the unified data interface. At the same time, the acquisition performance data device 103 collects performance data from the access system 102 through the access adapter. Moreover, the performance data transmission information of each access system 102 is different, so one access is suitable The adapter corresponds to an access system 102. Thus, the docking of the calling system 101 and the access system 102 is accomplished by the acquisition performance data device 103.

After receiving the command sent by the calling system 101, the collection performance data device 103 first determines whether the command is a performance data collection command, and if so, processes the command; otherwise, no processing is performed. When making a judgment, it can be judged according to the command code and the like carried in the command. When the command is a performance data collection command, obtaining a parameter of the performance data collection command, and determining an access adapter according to the parameter, accessing the corresponding access system 102; according to the transmission mode used in the access system 102, Determining the download adapter, the access adapter provides performance data transmission information of the access system 102, such as a transmission mode, a server address, a port number, a username, a password, and the like. Then, the above download adapter is called to transfer the performance data according to the performance data provided by the access adapter, download and save the performance data, and form a file save path; then call the performance acquisition function of the access adapter, and collect the downloaded performance data according to the file save path. .

Preferably, the collected performance data after the download is backed up, and then the downloaded performance data is deleted, and the backed up performance data is retained. Preferably, the downloaded performance data is filtered according to the preset filtering rule, and the performance data that meets the filtering rule is encapsulated according to the data format of the calling system 101, for example, when only part of the performance data in the performance data is needed. You can set the filtering rules to obtain the performance data that meets the filtering rules. The remaining performance data is filtered. You can also delete the performance data that does not meet the filtering rules. Preferably, the performance data after the downloading is validated, and the performance data verified by the validity is encapsulated according to the data format of the calling system; if the performance data fails the validity verification, the performance may be recorded and discarded. data. Preferably, the downloaded performance data is filtered according to the preset filtering rule; then, the performance data that satisfies the filtering rule is validated, and the performance data verified by the validity is used according to the data of the calling system 101. Format encapsulation. Of course, the steps of backup, delete, filter, and validity verification have no fixed execution order and can be processed according to actual needs. Finally, the encapsulated performance data is returned through the unified data interface according to a predetermined transmission protocol. Go to system 101.

Based on the foregoing network management system for collecting performance data, the embodiment of the present invention further provides a method for collecting performance data, as shown in FIG. 2, including the following steps:

Step 201: Analyze a performance data collection command sent by the calling system through the unified interface to obtain performance data collection parameters.

Specifically, the calling system implements docking with multiple access systems by collecting performance data devices, and acquires performance data from multiple access systems by collecting performance data devices. After receiving the command sent by the calling system, the device can determine whether the command is a performance data collection command according to the command code and other identifiers carried in the command. When the judgment result is a performance data collection command, the device parses the Performance data acquisition command to obtain performance data acquisition parameters; otherwise, it is not processed. The obtaining the performance data collection parameter may include: obtaining an access system identity, a file name of the performance data, and a remote full path of the performance data.

Step 202: Determine a corresponding access adapter according to the performance data collection parameter. Specifically, the corresponding access adapter may be determined according to the performance data collection parameter, such as the access system identity, and the connection is established with the corresponding access system. That is, the performance data collection parameters include accessing the system identity, determining the corresponding access adapter according to the identity of the access system, and accessing the access system through the access adapter.

Step 203: After downloading performance data from the access system corresponding to the access adapter, the downloaded performance data is encapsulated according to the data format of the calling system.

Specifically, after determining the access adapter, the access adapter can collect performance data from the access system. The download adapter is first called to download the performance data, and then the data acquisition function of the access adapter is called to collect the downloaded performance data, and the download adapter is determined by the performance data transmission mode in the access system corresponding to the access adapter. The specific process may be: determining a download adapter for downloading performance data according to the performance data transmission mode in the access system corresponding to the access adapter, for example, the performance data transmission mode in the access system is FTP (File Transfer Protocol) Send the agreement), you can use the FTP download adapter to download. If the performance data in the access system is in a non-file form, the FTP download adapter needs to file the performance data. At the same time, the download adapter can handle both local performance data and remote performance data. When the performance data is local performance data, the performance data can be directly copied; when the performance data is remote performance data, the performance data can be downloaded from the address specified by the access system and saved to the local; wherein, the performance data is copied and saved. The address is uniformly determined and guaranteed to be unique.

After the performance data download is completed, the data acquisition function of the access adapter is invoked to extract the performance data, and the performance data is encapsulated into a predetermined format, which can then be backed up, cleared, filtered, validated, etc., and finally the performance is performed. The data is encapsulated according to the data format used in the calling system, so as to be consistent with the data structure used by the calling system, which facilitates calling system identification and facilitates data transmission in the calling system. That is, the downloaded performance data is filtered and/or validated according to preset rules, and the performance data after filtering and/or validity verification is encapsulated according to the data format of the calling system.

Step 204: Return the encapsulated performance data to the calling system through the unified data interface. Specifically, the encapsulated performance data is returned to the calling system through a unified data interface according to a predetermined transmission protocol.

In addition, each processing step can be recorded in the log so that when a failure occurs, the log is viewed for fault location.

According to the foregoing description, the method for collecting performance data provided by the embodiment of the present invention is used to connect different access systems by using different access adapters, and the collected performance data is returned to the calling system by using a unified data format. It also standardizes and unifies the command interface and data interface, making full use of resources in the environment with diverse data formats, reducing the workload of development and maintenance, and effectively overcoming the problem that traditional data collection cannot be reused and is inefficient.

The access adapter control module 302 is configured to determine a corresponding access adapter according to the performance data collection parameter;

The performance data encapsulating module 303 is configured to: after downloading performance data from the access system corresponding to the access adapter, encapsulate the downloaded performance data according to the data format of the calling system; and the performance data returning module 304 is configured to pass The unified data interface returns the encapsulated performance data to the calling system.

Preferably, in another embodiment, the device further includes: a command listening module 305, configured to receive a command sent by the calling system through the unified command interface, and send the received command to the command parsing module 301;

The command parsing module 301 is further configured to determine whether the received command is a performance data collection command, and if yes, parse the performance data collection command; otherwise, no processing is performed.

Preferably, in another embodiment, the device further includes:

The performance download adapter control module 306 is configured to determine a download adapter for downloading performance data according to a performance data transmission manner in the access system corresponding to the access adapter.

Preferably, in another embodiment, the device further includes:

The performance data collection control module 307 is configured to invoke the download adapter to download performance data, and invoke the data collection function of the access adapter to collect the downloaded performance data, where the download adapter is in the access system corresponding to the access adapter. The performance data transmission method is determined.

Preferably, in another embodiment, the device further includes:

The performance data processing module 308 is configured to perform filtering and/or validity verification on the downloaded performance data according to preset filtering rules, and send the performance data after filtering and/or validity verification to the performance data encapsulating module 303. The performance data encapsulation module 303 is packaged in accordance with the data format of the calling system. The method for collecting performance data provided by the embodiment of the present invention is described in detail below by using specific embodiments. As shown in Figure 4, the following steps are included:

Step 401: Initially collect the performance data device; start the collection performance data device, initialize each module in the device, and initialize the access adapter and other functional components corresponding to each access system. Each access system needs an access adapter corresponding thereto, and the device manages the access adapter to complete the connection between the calling system and the access system. Each access adapter contains at least two functions: 1) Provide performance data transmission information used by the access system, such as transmission mode, server address, user name, etc.; 2) Collect performance data.

Step 402: Receive a command sent by the calling system. The command listening module can receive various commands sent by the calling system. After receiving the command, the command directly sends the command to the command parsing module, and then continues to listen for the command. .

Step 403: Determine whether the command is a performance data collection command; if yes, execute step 404; otherwise, do not process; after receiving the command sent by the command listening module, the command parsing module may judge according to the command code or other identifier carried by the command. Whether it is a performance data collection command, for example, when the command code of the command is 10400112, it can be judged as a performance data collection command.

Step 404: Parse the performance data collection command to obtain the performance data collection parameter. Specifically, the performance data collection parameter may include: a command code (eg, 10400112), an access system identity (eg, gsm_addis), and performance data to be collected. The remote full path of the file name and performance data (for example, pm40/100001_BSSB_201102151730.zip, , ) ₀ Moreover, the command parsing module can perform validity verification on the obtained performance data collection parameters.

Step 405: Determine an access adapter according to the performance data collection parameter. The access adapter control module determines, according to the performance data collection parameter, an identifier of the access system (such as an access system identity identifier), and determines to receive the performance data collection command. The access adapter can be connected to the access system where the performance data is located through the determined access adapter.

Step 406: Determine download adaptation of the download performance data according to the transmission mode in the access system. Specifically, each access system has a certain performance data transmission mode. First, the performance data transmission mode used by the access system is obtained from the access adapter, and the download performance is determined according to the performance data transmission mode. Data download adapter. If the performance data in the access system is in a non-file format, it needs to be converted to a file format first.

Step 407: Download and save the performance data. Specifically, the performance data collection control module invokes the download adapter to transmit information according to the performance data provided by the access adapter, download and save the performance data, and form a file save path. For example, the performance data transmission information of the access system provided by the access adapter is: a. Transmission mode = ? b, server address: IP address; c, port = 210; d, username = root; e, password = root. The download adapter can perform performance data transmission of a specific protocol, such as HTTP (Hyper Text Transport Protocol) / FTP. For example, the download adapter can download the specified performance data file using FTP according to the performance data transmission information: ftp: //IP address: 210/pm40/100001_BSSB_201102151730.zip, and stored in a unified file save path, such as:

Runtime/gsm_addis/pm/20110308120000/pm40/100001_BSSB_201102151 730.zip

The download adapter handles the download of two types of performance data, one for remote performance data and one for local performance data. When downloading remote performance data, the performance data can be obtained from the address specified by the access system and saved to the local. The performance data collection control module can adapt to multiple download modes, such as obtaining performance data files from HTTP/FTP addresses; For performance data, copy the performance data. The destination for downloading and copying performance data is uniformly determined and guaranteed by the performance data collection control module. Moreover, several common download methods, such as HTTP/FTP, can be hardened, and are extended by developers themselves if they are not satisfied.

Step 408: Collect performance data. Specifically, the performance data acquisition control module invokes the data collection function of the access adapter, and collects the downloaded performance data according to the file save path. After the performance data is saved to the specified address, the performance data needs to be extracted. The format of the performance data varies widely, and the performance data downloaded from each access system needs to be adapted differently. This When you call the access adapter's file-reading interface, you can extract the data and package it into a uniform format. That is, the performance data collection control module obtains the file save path of the performance data downloaded by the download adapter, and obtains the corresponding access adapter according to the access system identity, and then invokes the data read function of the access adapter to complete the The collection of performance data, and the performance data is encapsulated into data of a unified data structure.

Step 409: Back up and clear the downloaded performance data. Specifically, after the downloaded performance data is backed up, the downloaded performance data is deleted, thereby avoiding excessive or full disk files. The path rules for backing up performance data are determined by the performance data backup and cleanup module in the collection performance data device. After the backup performance data is backed up to the specified path, the performance data can be deleted. If the performance data is not backed up, it can be deleted directly. For example, you can back up the performance data downloaded in step 407 from the address: runtime/gsm_addis/pm/20110308120000/pm40/100001_BSSB_201102151730. zip , back to: backup/20110308/gsm_addis/pm/100001_BSSB_201102151730.zip, and the performance in the original address Data deletion.

Step 410: Filter performance data. After the performance data collection control module collects the performance data, the performance data may be transmitted to the performance data processing module to filter the performance data, directly obtain the required performance data, and use the required performance data. Filtered. During filtering, the downloaded performance data can be filtered according to preset filtering rules to obtain performance data that meets the filtering rules. For example, the performance data filtering module in the performance data processing module can include a filter rule base to increase or decrease the filter rules as needed. For example, in step 409, the performance data stored in 100001_BSSB_201102151730.zip contains all the data in the access system, and this collection only needs to collect data related to the call drop rate "Call Drop Rate". If the rest of the data is filtered, you can use "Call Drop Rate" as the filtering rule set in the filter rule base.

Step 411: Perform validity verification on the performance data; specifically, the performance data processing module The performance data verification module can verify the validity of the downloaded performance data, for example, the validity of the performance data can be verified, and the content of the verification can include the data format, the data sequence, the number of data, etc., and then will not be satisfied. The required performance data is removed and recorded so that the two parties can analyze and solve the problem in the event of a failure. For example, the data format and the number of data can be checked. When the required performance data is an integer type, and the collected performance data is a string, the validity check fails, and the performance data is discarded. When the required number of performance data is 20 and the number of collected performance data is 19, the validity check fails, and the 19 performance data are discarded. Moreover, the performance data verification module can include a verification strategy library and add or reduce, adjust, or replace the validity verification policy as needed.

Step 412: Encapsulate the downloaded performance data according to a data format of the calling system.

Specifically, although each access adapter can be unified with the performance data structure of the device, it is also required to unify the data structure of the device and the calling system, so the performance data needs to be encapsulated into a data interface format that can be recognized by the calling system. In order to return performance data to the calling system.

Step 413: Return the encapsulated performance data to the calling system through the unified data interface. Specifically, the performance data return module returns the encapsulated performance data to the calling system in a predetermined transmission protocol. For example, the EMB protocol can be used to return performance data to the calling system for invoking the system for subsequent processing.

At the same time, the status control module receives and records the working status of each module in the device in real time or at a time. The module is a long-running and existing component that controls the start and stop of each module, initializes all access adapters, etc., to achieve the purpose of device startup and management, and provides a log interface to receive status logs of the remaining modules and record them in a unified manner. Log.

The foregoing description shows that the method, the device, and the network management system for collecting performance data provided by the embodiments of the present invention use different access adapters for different access systems to connect, and the collected performance data is returned by using a unified data format. To call the system, and to standardize and unify The command interface and data interface make full use of resources in the environment with diverse data formats, reduce the workload of development and maintenance, and effectively overcome the problem that traditional data collection cannot be reused and low efficiency.
