Detailed Description
In order that the above-recited objects, features and advantages of the present application will be more clearly understood, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.
In one aspect, as shown in an embodiment of fig. 1, the present application provides a switch status monitoring method, including:
s100, updating the query period of the port by adopting an adaptive update interval;
s200, sending an acquisition instruction to a port based on a query period;
s300, receiving port bandwidth about a port returned by the switch;
s400, analyzing the port bandwidth to obtain a monitoring result.
When the bandwidth inquiry is carried out on the port, the inquiry period is not kept unchanged, but is updated based on the self-adaptive updating interval, so that the bandwidth of the switch is not occupied, and the occurrence probability of the condition that the change of the bandwidth in the port cannot be acquired in time is reduced.
Preferably, the determining of the adaptive update interval comprises:
the 1 st update interval and the 2 nd update interval are of preset time length;
starting from the 3 rd update interval, the update interval is determined in such a way that d is greater than or equal to 2;

Separately calculateAnd->Bandwidth characteristic value of (2);
the (d+1) th update interval is acquired based on the bandwidth characteristic value.
Specifically, in the present application, since the determination of the update interval is made based on the port bandwidths obtained in the first two update intervals, the present application is a predetermined time length for the first update interval and the second update interval. The predetermined time period may be 1 hour, 5 hours, or the like.
Preferably, the calculation is performed separatelyAnd->Bandwidth characteristic values of (a) comprising:
calculated using the following functionBandwidth characteristic value of (2):
wherein, the liquid crystal display device comprises a liquid crystal display device,representation->Bandwidth characteristic value, < >>Representation->Total number of port bandwidths contained in +.>Representation->Port bandwidth i, contained in the memory>Representing a preset port bandwidth, +.>Representing a preset port bandwidth comparison value, +.>Representing the calculated proportion of the setting,/->；
Calculated using the following functionBandwidth characteristic value of (2):
wherein, the liquid crystal display device comprises a liquid crystal display device,representation->Bandwidth characteristic value, < >>Representation->Total number of port bandwidths contained in +.>Representation->The port bandwidth j contained therein.
In the above embodiment, the bandwidth characteristic value is calculated from two aspects of the average value of the port bandwidths and the variance of the port bandwidths in the set, so that the bandwidth characteristic value can represent the average size of the port bandwidths in the set and the degree of difference of the sizes of the port bandwidths, which is favorable for more comprehensively representing the characteristics of the port bandwidths in one update interval, thereby obtaining the update interval with high self-adaption degree obtained by calculation.
Specifically, the preset port bandwidth may be the maximum value of the bandwidth that the port can be used in the switch, and the preset port bandwidth comparison value may be the square of the maximum value of the bandwidth that the port can be used. The maximum value of the bandwidth that a port can use refers to the bandwidth that the port can actually use, because some of the bandwidth in the port is required for information transmission of various management protocols.
Preferably, acquiring the (d+1) th update interval based on the bandwidth characteristic value includes:
if it isThe (d+1) th update interval is calculated using the following function:

if it isThe (d+1) th update interval is calculated using the following function:

Specifically, the latest update interval is calculated based on the characteristic value of the bandwidth in the latest two update intervals, so that the adaptive change of the update interval is realized.When (when)When the port bandwidth changes relatively slowly in the two latest update intervals, the application adopts the update interval calculation function with relatively small change amplitude to calculate the new update interval, and when>In this case, the port bandwidth changes faster in the two latest update intervals, so that the update interval calculation function with larger change amplitude is selected to calculate a new update interval, thereby realizing adaptive change of the update interval, so that the port with smaller change amplitude of the port bandwidth is updated in the acquisition period by using a longer update interval, and the port with larger change amplitude of the wide port bandwidth is updated in the acquisition period by using a shorter update interval. In addition, in the process of calculating the update interval, when +.>Is greater than->When the utilization rate of the port bandwidth is reduced, the monitoring requirement of the port bandwidth is reduced, and the application correspondingly increases the update interval, otherwise, correspondingly decreases the update interval, and the increase or decrease amplitude of the update interval is equal to->And->The absolute value of the difference between them is correlated, thereby further improving the adaptation of the update interval.
In particular, the bandwidth characteristic value threshold may be one quarter of the maximum value of the bandwidth that the port can use.
Preferably, the calculation function of the query period is:
andindicating the inquiry period corresponding to the d-th update interval,/->And->Representing the first port bandwidth mean and the second port bandwidth mean, respectively,/->，/>Representing time intervalsIn, the set of port bandwidths returned by the switch, +.>Indicate start of calculation +.>Is (are) time of day->Represents the set sampling interval, +.>Representing a preset third duration, +.>Representation->Total number of port bandwidths contained in +.>Representation->Port bandwidth u, in (a)>Representing the maximum value of port bandwidth;
，/>representing time interval +.>In, the set of port bandwidths returned by the switch, +.>Representation->Total number of port bandwidths contained in +.>Representation->Port bandwidth v in (a).
Specifically, the query period andand->The application increases the value of the inquiry period, otherwise, decreases the value of the inquiry period, thus the inquiry period can change along with the change of the change speed of the port bandwidth, and the occurrence probability of the condition that the port bandwidth of the port with smaller inquiry change speed is not occupied by the switch due to the adoption of the fixed inquiry period is reduced. At the same time make at the portWhen the bandwidth is changed rapidly, the inquiry period is shortened, and the change condition of the port bandwidth in the port can be obtained in time.
The theoretical port bandwidth is shown. For example, if one port is configured to be 1GB bandwidth, thenIs 1GB. />The value of (2) may be 10S.
Preferably, updating the query period of the port with the adaptive update interval includes:
after the d update interval is finished, entering a d+1th calculation stage, and calculating a d+1th update interval and a query period corresponding to the d+1th update interval in the calculation stage;
and after the query period corresponding to the (d+1) th update interval and the (d+1) th update interval is calculated, entering the (d+1) th update interval.
Preferably, the fetch instruction contains the number of the port for which a port bandwidth query is required.
Specifically, the switch queries the corresponding port according to the number.
The get instruction may be sent based on the SNMP protocol.
Preferably, analyzing the port bandwidth to obtain a monitoring result includes:
judging whether the port bandwidth exceeds a set port bandwidth threshold, if so, judging that the monitoring result is that the port bandwidth is abnormal.
In particular, the port bandwidth threshold may be 90% of the maximum bandwidth that the port can be used.
