Abstract
The invention discloses a method and a device for updating simple network management protocol (SNMP) management data. When a management end device needs latest management data, main agent equipment does not immediately send the management data in a management information base (MIB) through sub agent equipment; the sub agent equipment cancels a data area in the current MIB, triggers system data acquisition equipment to acquire latest management data, fills the acquired management data into the MIB, then reregisters the data area in the MIB to the main agent equipment, and sends the latest management data to the main agent equipment; and the main agent equipment sends the latest management data to the management end device. Therefore, a managed end device does not actively update the management data, but executes update when the management end device needs the new management data, equivalently passive update, so system performance loss and input output (IO) load are lightened.
Description
Technical field
The present invention relates to the Data Update technology, particularly a kind of renewal Simple Network Management Protocol (SNMP, Simple Network Management Protocol) method of managing data and device.
Background technology
The SNMP system comprises management end device and Managed Client device, and wherein the Managed Client device comprises master agent equipment, sub agent equipment, management information base (MIB, Management InformationBase) and system data collecting device again.Above-mentioned sub agent equipment needs to the master agent facility registration, is data field among the sub agent devices allocation MIB by master agent equipment, by the system data collecting device management information that collects is filled into this data field.
In the prior art, the update method that mainly has following two kinds of snmp management data at present:
The first, Fig. 1 is the theory diagram of the update method of first kind of snmp management data in the prior art, in this update method, after the system data collecting device obtains new management data, new management data is filled into is the data field of sub agent devices allocation among the MIB, notify the master agent equipment management data to upgrade simultaneously, master agent equipment obtains new management data by sub agent equipment from MIB.After master agent equipment receives the browsing data order of management end transmission, new management data is sent to the management end device.
The second, Fig. 2 is the theory diagram of the update method of second kind of snmp management data in the prior art, in this update method, in sub agent equipment, timer is set, whenever the timer timing is overtime, sub agent device trigger system data collecting device is gathered current management data and is filled into and is the data field of sub agent devices allocation among the MIB.After master agent equipment receives the browsing data order of management end transmission, from MIB, obtain new management data by sub agent equipment, send to the management end device then.
As can be seen, the update method of above-mentioned any management data no matter, all be initiatively to carry out renewal by the Managed Client device, in the time of may appearing at the management end device and not needing new management data, the Managed Client device also in the situation of bringing in constant renewal in management data, has so just increased system performance loss and input and output (IO) load.
Summary of the invention
The invention provides a kind of update method of snmp management data, use this method can mitigation system performance loss and IO load.
The invention provides a kind of updating device of snmp management data, use this device can mitigation system performance loss and IO load.
Technical scheme of the present invention is achieved in that
A kind of update method of snmp management data, the Managed Client device comprises: master agent equipment, sub agent equipment, system data collecting device and management information bank MIB; Key is that this method comprises:
The browsing data order that master agent equipment and sub agent equipment receiving management end device send;
Sub agent equipment is nullified the data field among the current MIB;
Sub agent device trigger system data collecting device is filled into data field among the MIB with up-to-date management data, and sub agent equipment obtains the up-to-date management data of the data field that is filled among the MIB;
Sub agent equipment re-registers the data field among the MIB;
Sub agent equipment sends up-to-date management data by master agent equipment to the management end device.
A kind of updating device of snmp management data, this device comprises: master agent equipment, sub agent equipment, system data collecting device and management information bank MIB; Key is,
Described master agent equipment is used for the browsing data order that the receiving management end device sends; Receive the up-to-date management data that sub agent equipment sends, send to the management end device;
Described sub agent equipment is used for the browsing data order that the receiving management end device sends; Nullify the data field among the current MIB; Triggering system data acquisition equipment executable operations; Obtain the up-to-date management data of the data field among the MIB; Re-register data field among the MIB to master agent equipment; Up-to-date management data is sent to master agent equipment;
Described system data collecting device, by the sub agent device trigger, the data field that is used for gathering up-to-date management data and is filled into MIB.
As seen, in the update method of snmp management data of the present invention, when the management end device needs up-to-date management data, master agent equipment can't send to the management end device with existing management data among the MIB at once by sub agent equipment, but by the data field among the current MIB of sub agent equipment elder generation cancellation, the up-to-date management data of triggering system data acquisition equipment collection is filled among the MIB again, re-register data field among the MIB to master agent equipment then, up-to-date management data is sent to master agent equipment, and this moment, master agent equipment sent to the management end device with up-to-date management data again.Thus, the Managed Client device is not a renewal management data initiatively, but when the management end device needs up-to-date management data, just goes to carry out and upgrade, and is equivalent to a kind of passive renewal, has alleviated system performance loss and IO load.
