Design cycle of the present invention is as follows:
1, the oid of the definite monitoring parameter that will gather, type etc.This will be decided as the case may be, and each equipment of each producer, their certain monitoring parameter all have and identifies for unique OID number.Determined OID, the OID of filtering useless.
2, set up embedded database, a newly-built new database table, what this table was preserved is OID and corresponding field title (this field name is corresponding with the field name of preserving monitoring parameter table, is the convenience in order to develop and to safeguard).Table comprises field name, oid, operation version, action type (get, set, table, trap, getAlarm).The equipment that every money is identical adopts identical field name, the corresponding field name of each OID, later on only need obtain device type and just can know the field name of OID correspondence, take out the value that to upgrade the correspondence of preservation value of consult volume table after this field name according to device id.
3, build monitoring parameter table (table of the preservation value of consult volume of mentioning in 2), preserve parameter information.Field name, field value, field value length, field equipment id.This table and top mapping table can be interrelated by equipment id.
4, some qualifications of database: limit the mode of alarming value storage, such as: handle by the receiving management process, handle the back and judge be alarming value, we are set at 01 etc. the renewal value of consult volume;
5, according to the IP address, the monitoring that obtains this collector from database is equipment id number of SNMP type equipment, because the equipment of collector monitoring is not necessarily supported SNMP, so when data base initialize, initiate equipment must be provided with device type.
6, from database, obtain many of the OID(of device id correspondence), and the action type (get, set, table, getAlarm) of corresponding OID, every kind of corresponding processing threads of operation.Wherein get and table are same thread, but Processing Interface is different.
7, asynchronous transmission operation requests
8, managing process directly decomposes return information, calls relevant treatment interface (according to the specific requirement of equipment, each distinct device all has corresponding processing function), decomposes the value that obtains and temporarily is kept in the self-defining structure of program.
9, obtain the field name of this equipment of parameter table (in 3) id and each OID correspondence,,, when searching the corresponding field title, must obtain correct equipment id so the information of returning is asynchronous because be the asynchronous transmission request.Because the ip address of meeting bound targets machine (snmp managed device) in the information of returning is so we can obtain device id (in 5) according to this IP.
10, the value and the field name of structure preservation according to correct device id, are upgraded value corresponding in the parameter table.
Collect two kinds of basic modes of data from managed devices:
Polling mode (polling-only): initiatively to the order of agent process transmission inquiry or setting, agent process sends the operation signal of inquiry or setting to managing process again to agency's MIB then, thereby obtains or revise corresponding information.Mode (interrupt-based) based on interruption: when anomalous event took place, agent process can be notified managing process on one's own initiative, and needn't wait for the arrival of polling cycle.
Usually polling mode is used in combination with interrupt mode to remedy defective separately, is referred to as self-trapping controlled polling mode (trap-directed polling).
Management station and agency carry out information interaction needs unified interface, and snmp protocol adopts the MIB management information bank to realize.Structure of management information SMI grammer is followed in the definition of mib file interface, with the definition information description in mib file.The value of proxy variable is kept in the mib file, and management end inquiry and setting operation all are the operations to agent side mib file variable.SNMP GET, SET operation all is to have network management system (managing process) to initiate, and act on behalf of passive reception and operate accordingly, and the agency can initiatively send some great message that incident took place to management end by trap.
