In described Query Result display unit, comprise common variables inquiry and table inquiry.In described SNMP operational module, TrapReceive realizes the filtering function that trap receives, and the trap that does not meet the trap condition of acceptance can not show that the condition of filtration can be ip address, the keyword that comprises among time or the trap; TrapSend can send the ip address of trap to appointment, the specific oid information of binding in the trap bag.In described data drawing list unit, comprise two chart modules, one is the curve chart that shows the data variation on node same day, another is the curve chart that shows all historical datas of node.
The course of work that this example is implemented is: the present invention at first carries out the parsing of mib file, as shown in Figure 1.To judge at first behind the path that has obtained mib file that it is single file or catalogue (comprising several single files under the catalogue), if catalogue, just obtain the file array below it, be converted into operation monofile.
When single mib file is resolved, at first use the mibble kit that it is resolved, but mibble kit defectiveness in being to use: the one, the syntax attribute that obtains mib object that can't be correct; The 2nd, can only be to the document analysis of SMIv2, the file of SMIv1 can't be discerned.So just use two other main class: readSyntax and readMib.The former is after mibble is to document analysis, reads file with readSyntax again, obtains correct syntax.If the latter is when finding that mibble can't resolution file, removes to read this document with readMib.Finally realized parsing fully to mib file.Analysis result has obtained two Hash table: mib_database and name2node.The mib_databases key assignments is OID, and value is a mib_detail object, and this object has been preserved all information (as name, oid, syntax, information such as access) of this MIB node; The name2node key assignments is name, and value is a mib_detail object.The whole descriptors that can obtain this node by the OID or the name of a MIB node so just.
The subscriber interface module flow process as shown in Figure 2.This module most important part is the generating portion of MIB tree.According to the analysis result of front, obtained the OID of all mib objects, information such as name to mib file.OID is the tree-shaped result who is similar to " 1.3.6.1.2.1 ".A newly-built root node on tree control at first, it is 1.3 that its OID is set, and travels through Hash table then, obtains all OID, if find this OID father node is arranged, and just becomes its child node.The final MIB of formation sets.The MIB tree will be added mouse event and be realized function.
Flow chart in the middle of Fig. 2 has shown the left mouse button function.After certain node has obtained the left mouse button incident, according to its node name (name of mib object just), obtain its mib_detail object according to this Hash table of name2node then, also just obtained the descriptor of this node.Show in the MIB details table below the MIB tree then.
The flow chart on Fig. 2 the right has shown the right mouse button function.Right-click menu comprises as follows: Get, Getnext, Getbulk, Set, Walk, Table view, Graph View.These seven menu items have been realized the major function of this network management browser.After the click right, whether program decision node type is form as interpretation, and whether grammer is shaping, if do not satisfy, and Tableview then, these two menus of Graph View are not enabled state of grey.Also has some other similar decision operation etc.After obtaining the menu click, jump to the events corresponding handling procedure.
Snmp operational module flow process such as Fig. 3. this module is made up of eight classes: snmpget, snmpgetnext, snmpgetbulk, snmpwalk, snmpset, snmptable, TrapReceive and TrapSend realize corresponding snmp function respectively.The snmpget class realizes the get-request operation: extract one or more parameter values from agent process.The snmpgetnext class realizes the get-next-request operation: extract the next parameter value of closelying follow the parameter current value from agent process.The snmpgetbulk class has realized the getbulk function, and the function that getbulk provides the single query manipulation to encapsulate a plurality of requests improves by the efficient of the visit of management information.The snmpwalk class has realized MIB traversal of tree query function.The snmpset class realizes the set-request operation: one or more parameter values that agent process is set.The snmptable class has realized the inquiry of his-and-hers watches nodes.These two classes of TrapReceive and TrapSend then realize reception and the transmission to trap respectively.The present invention uses the snmp4j kit to realize concrete snmp protocol.Snmp4j is a project of increasing income that realizes SNMP (Simple Network Management Protocol) agreement with Java. it supports to manage and respond with the form of order line.Snmp4j is that pure Object-Oriented Design and SNMP++ (realizing SNMPv1/v2c/v3 with C++) are similar.A trap receiving filtration device also will be set in the trap receiving unit, and filtercondition comprises the time, three of ip and keywords, and the trap that only satisfies condition just can be revealed.
Database module flow process such as Fig. 4.Characteristics of this software are can automatic data collection, and store in the database.Be exactly specifically behind the node that the user has selected to monitor (syntax of this node must be integer, counter or gauge type), program will be carried out the get operation at a certain time interval, and the result is saved in the database.Historical data in the database has reflected the state variation of monitored device a period of time, if show with the form of chart song, just becomes very directly perceived and convenient of ground, and this software just has this function.The data drawing list display module is responsible for the form of data of database with chart shown, and by data and curves, reflects the variation of data intuitively.The data drawing list module is divided into two chart modules, and one is the curve chart that shows the data variation on node same day, and another is the curve chart that shows all historical datas of node.
Database module also will have the function of data retrieval, allows the data of specific node in the user search certain hour section, the flow chart in the middle of flow process such as Fig. 4.
Database module also will be responsible for the arrangement of data, just deletes unwanted data record, the right figure of flow chart such as Fig. 4.This module shows the data rows in all databases, allows the user need select the row of deletion, if the data rows of selecting just in use, can't delete with regard to bulletin.
