The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions for other terms will be given in the following description.
It should be noted that the terms "first", "second", and the like in the present disclosure are only used for distinguishing different devices, modules or units, and are not used for limiting the order or interdependence relationship of the functions performed by the devices, modules or units.

The embodiment of the application provides a fault positioning method, as shown in fig. 1, specifically including the following steps:
s101, acquiring alarm information.
Wherein, the alarm information includes: an event stream of at least one alarmed fault event, the event stream of each fault event comprising: the time of occurrence of the fault event, the device to which the fault event relates.
It should be noted that the alarm information may further include description information of the fault, so that a subsequent worker may further analyze a root cause of the fault in combination with the description information of the fault and the device that is finally determined in the present application and causes the fault event.
Specifically, when the data center is abnormal, the alarm information of the abnormality is received and obtained.
S102, aiming at each device in the time slice, establishing a normalized two-dimensional event scatter diagram of the device.
The device is characterized in that a normalized two-dimensional event scatter diagram of the device shows related events of the device; relevant events of the device include: the method comprises the following steps that a fault event corresponding to equipment and a fault event corresponding to equipment of which the routing distance meets the threshold requirement are obtained; the time slice is a time period between the occurrence time of the fault event and the end point of the interval time; the interval time is a time period between the start point and the end point; the time slice is a time period between the occurrence time of the fault event and the end point of the interval time; the device in the time slice comprises: each device involved in a fault event occurring within a time slice.
It should be noted that the "distance" between the devices in the data center may represent the spatial position relationship between the devices. For example, in a complex network, path information between any two "reachable" devices may be obtained based on routing entries in a routing table, and the distance may be defined as the minimum number of hops experienced in a reachable path. The correlation between two devices is characterized by setting a threshold value. For example, if the threshold is set to 3, it is considered that the correlation of the event or failure between the devices exists only when the "distance" between the devices is less than or equal to 3, and if it is greater than 3, the correlation factor is ignored because the "distance" is too far. The threshold value may be adjusted by a technician or the like according to an actual application, and is not limited herein.
It should be further noted that the size of the time interval may be adjusted and tested according to different device types, different levels of devices, and different monitoring granularities in the same scene.
Specifically, a normalized two-dimensional scattergram of each device is established for each device in the time slice.
Optionally, in another embodiment of the present application, an implementation manner of step S102, as shown in fig. 2, includes:
s201, aiming at each device in the time slice, establishing a two-dimensional event scatter diagram of the device.
The horizontal axis of the two-dimensional event scatter diagram refers to time, and the vertical axis of the two-dimensional event scatter diagram refers to the routing distance between the devices; relevant events of the equipment are shown on the two-dimensional event scatter diagram of the equipment, and the relevant events of the equipment comprise: the routing distance between the device and the routing equipment meets the threshold requirement.
Specifically, as shown in FIG. 3, with time [ t, t + τ ]]A two-dimensional event scatter diagram of the device R1 is created with the route distance between the devices as the horizontal axis and the vertical axis, and the interval of the vertical axis is limited by the "threshold" in the above step S102, and the range of the vertical axis may be 0 to 3 with the threshold as an example. The scatter in fig. 3 represents events related to device R1, wherein events related to device R1 include: a fault event corresponding to device R1 itself, and a fault event corresponding to a device whose routing distance from device R1 meets the threshold requirement. Taking the scatter point labeled A in FIG. 3 as an example, A represents event E1 generated by device R2, and the abscissa in FIG. 3 is the time, e.g., t, of event E1 generated by device R21The ordinate is the distance between R2 and R1, e.g. d12Then the coordinate of A is (t)1，d12)。
S202, respectively normalizing the abscissa axis and the ordinate axis of the two-dimensional event scatter diagram to obtain a normalized two-dimensional plane rectangular coordinate system.
S203, normalizing the coordinates of each relevant event of the equipment displayed by the two-dimensional event scatter diagram to obtain a normalized two-dimensional event scatter diagram of the equipment in a normalized two-dimensional plane rectangular coordinate system.
Specifically, as shown in fig. 4, the coordinate system and the coordinates in fig. 3 are normalized to obtain a normalized two-dimensional event scattergram of the device R1. If the original coordinate is (t, 0), the normalized coordinate is (0, 0); the original coordinate is (t + τ, 0), and then the normalized coordinate is (1, 0); the original coordinates are (0, 3), the normalized coordinates are (0, 1); the original coordinate is (t)1，d12) Normalized coordinates are then
And the like.
It should be noted that, after obtaining the normalized two-dimensional event scatter diagram of a single device, the correlation between all events in the time slice may be calculated by converting the correlation into euclidean distances. For example, after obtaining a normalized two-dimensional event scatter plot for device R1 within a time slice (t, t + τ), the distance from any point in the plot to the origin of the coordinate system is calculated, and this distance may represent the correlation between the event generated by the device to which the point belongs and device R1 at time t. Taking point a in fig. 4 as an example, the distance D between a and the origin of the coordinate system,
optionally, in another embodiment of the present application, an implementation manner of step S203 includes:
and regarding each event related to the equipment displayed by the two-dimensional event scatter diagram, taking the quotient of the numerical value of the abscissa of the event and the time interval as the abscissa of the normalized two-dimensional event scatter diagram of the equipment of the event, and taking the quotient of the numerical value of the ordinate and the threshold as the ordinate of the normalized two-dimensional event scatter diagram of the event.
S103, aiming at each device in the time slice, drawing a frequency histogram corresponding to the normalized two-dimensional event scatter diagram of the device, and obtaining the statistic of the device by utilizing the frequency histogram statistics.
Specifically, since the coordinate system of the two-dimensional event scattergram is normalized, the distance from any point in the rectangular space shown in fig. 4 to the origin of the coordinate system belongs to
The group number m and the group distance can be set in advance according to the current scene and the required granularity
The boundary range of each group of data is according to a left-closed right-open interval:
the horizontal axis represents a continuously obtainable value of the sample data, the vertical axis represents a value of frequency divided by the group pitch, and a frequency distribution histogram is plotted in a rectangular coordinate system with a high quotient of frequency and group pitch and a base rectangle of group pitch. The number of sample data falling in each group is called frequency, and the frequency divided by the total number of samples is the frequency. Also, it can be appreciated that the fewer the packets, the more the data is concentrated, and the more the packets, the more the data is dispersed.
After the frequency histogram corresponding to the normalized two-dimensional event scatter diagram of the device is drawn, the statistics of the device can be obtained by utilizing the frequency histogram statistics.
And S104, evaluating the statistic of each device according to a preset evaluation rule, and determining the device causing the fault event.
Specifically, different preset evaluation rules are selected according to different scenes, statistics of each device are evaluated, a single value or a vector value is obtained to represent the score of the device in the time slice, and the smaller the score is, the closer the device is to the core of the time in the time slice is, namely, the more likely the device is to cause a fault event.
Optionally, in another embodiment of the present application, the routing distance between the devices refers to: the minimum number of hops experienced by the two devices in the reachable path is shown in the routing table.
Optionally, in another embodiment of the present application, an implementation of obtaining statistics of a device by using frequency histogram statistics includes:
at least one or a combination of the following parameters of the device are derived using frequency histogram statistics.
The parameter may be, but is not limited to, a mode, a median, an arithmetic mean, and a weighted mean, among others.
According to the scheme, in the fault positioning method provided by the application, firstly, the alarm information is obtained; wherein, the alarm information includes: an event stream of at least one alarmed fault event, the event stream of each fault event comprising: the occurrence time of the fault event, the equipment involved in the fault event; then, aiming at each device in the time slice, establishing a normalized two-dimensional event scatter diagram of the device; the device is characterized in that a normalized two-dimensional event scatter diagram of the device shows related events of the device; relevant events of the device include: the method comprises the following steps that a fault event corresponding to equipment and a fault event corresponding to equipment of which the routing distance meets the threshold requirement are obtained; the time slice is a time period between the occurrence time of the fault event and the end point of the interval time, and the device in the time slice comprises: each device involved in a fault event occurring within a timeslice; then, aiming at each device in the time slice, drawing a frequency histogram corresponding to a normalized two-dimensional event scatter diagram of the device, and obtaining the statistic of the device by utilizing the frequency histogram statistics; finally, evaluating the statistic of each device according to a preset evaluation rule, and determining the device causing the fault event. The method and the device achieve the purpose of screening effective information in the alarm information in a short time, thereby helping front-line operation and maintenance personnel to quickly locate the fault reason.
Another embodiment of the present application provides a method for locating a fault, as shown in fig. 5, including:
s501, acquiring alarm information.
S502, aiming at each device in the current time slice, establishing a normalized two-dimensional event scatter diagram of the device.
S503, aiming at each device in the current time slice, drawing a frequency histogram corresponding to the normalized two-dimensional event scatter diagram of the device, and obtaining the statistic of the device by using the frequency histogram statistics.
S504, evaluating the statistic of each device according to a preset evaluation rule, and determining the device causing the fault event.
It should be noted that, the specific implementation process of steps S501 to S504 may refer to steps S101 to S104, which are not described herein again.
And S505, obtaining feedback information fed back by the operation and maintenance personnel.
Wherein the feedback information is used to indicate whether the device causing the fault event determined in step S504 is the real device causing the fault event.
It should be noted that, after receiving the device causing the fault event determined in step S504, the operation and maintenance personnel manually determine whether the device causing the fault event determined in step S504 is the device causing the fault event, and feedback the device at the operation interface through a touch screen or the like.
Specifically, if the feedback information is used to indicate that the device causing the fault event determined in step S504 is not the real device causing the fault event, that is, if an error is determined, step S506 is executed; if the feedback information is used to indicate that the device causing the fault determined in step S104 is a real device causing the fault, i.e., it is determined to be correct, the positioning of the fault is ended.
S506, the current time slice is redetermined, and the step S502 is executed again aiming at the current time slice which is determined each time.
The current time slices determined each time are time periods between the occurrence time of the fault event and the end point of the current interval time, and the time interval in the current time slice determined at the next time is longer than the time interval in the current time slice determined at the previous time.
Since the duration of a failure cannot be predicted when the failure occurs, there is a possibility that erroneous determination or erroneous determination may occur due to an error in the time interval τ at which the time slices are selected, using the time slices in the upper half of fig. 6. Therefore, the selection of the required time interval τ needs to be increased as the flow of events generated when the fault occurs is increased.
Specifically, the time slice shown in the lower half of FIG. 6 may be used, assuming that the fault is at t0The time is generated, the value of tau is set to 1min firstly, namely time slice 1 in the lower half of FIG. 6, all the steps from S501 to S504 are executed, and [ t ] is obtained0,t0+1]The device Q1 closest to the event center; the operation and maintenance personnel manually judge whether the Q1 is the equipment causing the fault or not to the Q1; if Q1 is not the device causing the failure, then as the failure time goes by, the value of τ is changed to 2min, i.e. time slice 2 in the lower half of fig. 6, i.e. the current time slice is re-determined as described above, and all steps from steps S501 to S504 are repeated again, resulting in [ t [ [ t ] t0,t0+2]The device Q2 closest to the event center (which may be the same as Q1 or different from Q1), and so on until the cause of the fault is completely found.
