In this embodiment of the present application, the network management system includes at least one computer device cluster, and taking one of the computer device clusters as an example, the computer device cluster may include one server and a plurality of nodes. In practical applications, the alarm generated by each computer device cluster may be regarded as an individual alarm set, and the computer device may determine the root cause alarm node in the alarm set by using the scheme described in the present application for the alarm set.
In the embodiment of the present application, the node may be various network elements, a server, and the like.
In the embodiment of the present application, the first association topology may be constructed according to an association relationship between nodes or an association relationship between a node and a server. As shown in fig. 1, the computer device cluster includes a server and 4 nodes, where node 1, node 2, node 3, and node 4 are 4 nodes dependent on server a, node 4 is dependent on node 2, node 2 is dependent on node 3, and node 1 is an independent node and does not generate a dependency relationship with other nodes.
In the embodiment of the present application, the existence of the association between two entities may be represented by identifying "1", and the absence of the association between two entities may be represented by identifying "0". The association between the entities in the computer cluster shown in fig. 1 may be as shown in table 1:
TABLE 1
| | Node | 1 | Node 2 | Node 3 | Node 4 | |
| |
1 | 1 | 1 | 1 | 1 | |
| |
1 | 1 | 0 | 0 | 0 | |
| Node 2 | 1 | 0 | 1 | 1 | 1 | |
| Node 3 | 1 | 0 | 1 | 1 | 0 | |
| Node 4 | 1 | 0 | 1 | 0 | 1 |
In the embodiment of the application, because the association relationship exists among the nodes, when a certain node generates an alarm by mistake, other nodes with association may also generate an alarm. For example, an application is installed on a server, and when the application generates an error alarm, the server may also generate an alarm. And under the condition that the alarm generated by a certain node causes the triggering alarms of other nodes, the node which initially generates the alarm is the root cause alarm node.
In the embodiment of the application, when the node is abnormal, the node reports the alarm information to the computer equipment. Those skilled in the art will appreciate that the alarm is propagated along the first associated topological graph, for example, in the embodiment shown in fig. 1, when the node 2 and the node 3 alarm, the node 3 is the root alarm node, i.e. the node 3 is the trigger alarm of the node 2. If a node is an independent node (e.g., node 1), that is, there is no association between the node and other nodes, in this case, when an alarm is generated on the node, it may be determined that the node is a root cause alarm node, that is, the alarm generated by the node is a root cause alarm.
In the following, a schematic flow chart of an alarm analysis method provided in the embodiment of the present application shown in fig. 2 is described in detail how to determine a root cause alarm node in the embodiment of the present application, which may include, but is not limited to, the following steps:
step S200, a second association topological graph formed by at least one alarm node is obtained according to a first association topological graph, wherein the first association topological graph is used for representing the association relation of the plurality of nodes, and the alarm node is a node generating an alarm phenomenon in the plurality of nodes.
In the embodiment of the present application, a first association topology shown in fig. 1 is taken as an example, where a node 1 is normal; the node 2, the node 3, the node 4, and the server a may report the alarm information to the computer device, and in this case, a second association topology map (as shown in fig. 3A) formed by at least one alarm node is obtained based on the first association topology map shown in fig. 1, so that the root cause alarm node may be determined based on the second association topology map shown in fig. 3A.
Referring to fig. 3A, when the node 2, the node 3, the node 4, and the server a among the nodes in fig. 1 generate an alarm, for convenience of description, the node generating the alarm is labeled in fig. 3A, and the node generating the alarm is referred to as an alarm node.
In practical applications, when the node 2, the node 3 and the node 4 generate alarms, the computer device may obtain alarm information generated by each alarm node, so that the second associated topological graph formed by the alarm nodes may be extracted from the first associated topological graph according to the alarm information.
In a possible implementation manner, the computer device may obtain the alarm information reported by at least one alarm node within a preset time range. Specifically, the preset time range may be preset by the computer device, or may be set by the computer device according to the acquired alarm rule, and the embodiment of the present application is not particularly limited. Taking the preset time range as the preset time range of the computer device as an example, the preset time range of the computer device may be half an hour, and in this case, the computer device counts the alarm information generated by the alarm node in the time range every half an hour. Taking the preset time range as an example set by the computer device according to the acquired alarm rule, the computer device determines that the number of alarms occurring in the time period from 8:00 to 9:00 is the largest, and in this case, the time range set by the computer device may be 5 minutes, that is: and the computer equipment counts the alarm information generated by the alarm nodes in the time range every 5 minutes in the time period from 8:00 to 9:00 so as to determine the root cause alarm nodes as soon as possible and avoid large-area service downtime.
In this embodiment of the present application, the second association topological graph may include at least one alarm chain, for example, as shown in fig. 3B, the second association topological graph includes one alarm chain, and the alarm chain may be represented as: node 4-node 2-node 3; for another example, as shown in fig. 3C, the second association topology includes two alarm chains, where alarm chain 1 may be represented as: node 4-node 2-node 3-node 5; alarm chain 2 may be represented as node 4-node 2-node 1.
And S302, acquiring the pointing relation of each alarm node in the second associated topological graph.
In the embodiment of the application, the second association topological graph includes a distance relationship between the alarm nodes, and the distance relationship is used for describing an association degree between the alarm entities. The distance relationship is infinite if there is no association between two alarm nodes, and the distance relationship is unit length 1 if there is an association between two alarm nodes. Here, the description about determining the distance relationship between the alerting entities is only an example and should not be construed as a limitation.
In this embodiment of the application, a distance relationship corresponding to each alarm node in the second association topology shown in fig. 3A may be as shown in table 2:
TABLE 2
| Server A | Node 2 | Node 3 | Node 4 | |
| Server A | 0 | 1 | 1 | 2、3 |
| Node 2 | 1 | 0 | 1 | 1 |
| Node 3 | 1 | 1 | 0 | 2 |
| Node 4 | 2、3 | 1 | 2 | 0 |
In this embodiment of the application, a distance relationship corresponding to each alarm node in the second association topology shown in fig. 3B may be as shown in table 3:
TABLE 3
| Node 2 | Node 3 | Node 4 | |
| Node 2 | 0 | 1 | 1 |
| Node 3 | 1 | 0 | 2 |
| Node 4 | 1 | 2 | 0 |
In the embodiment of the present application, the distance relationship corresponding to each alarm node in the second association topology diagram shown in fig. 3C may be as shown in table 4:
TABLE 4
| |
Node 2 | Node 3 | Node 4 | Node 5 | |
| |
0 | 1 | Infinity(s) | 2 | Infinity(s) |
| Node 2 | 1 | 0 | 1 | 1 | 2 |
| Node 3 | Infinity(s) | 1 | 0 | 2 | 1 |
| Node 4 | 2 | 1 | 2 | 0 | 3 |
| Node 5 | Infinity(s) | 2 | 1 | 3 | 0 |
As shown in table 4, when the distance relationship is 1, it means that two nodes are directly connected; when the distance relation is larger than 1, the two nodes are indirectly connected. Taking the distance relationship between the node 1 and the node 3 as an example, when the distance relationship between the node 1 and the node 3 is infinite, it indicates that there is no association relationship between the node 1 and the node 3.
In a possible implementation manner, the implementation process of obtaining the pointing relationship of each alarm node in the second association topology may include: determining a relative distance between the reference node and each alarm node contained in the second associated topological graph; the reference alarm node is any one of at least one alarm node; and then, under the condition that the relative distance meets a set value, determining the direction relation between the alarm nodes according to the relative distance. Here, the set value may be 1 or-1.
Taking the second associated topological graph shown in fig. 3B as an example, taking the node 2 as a reference alarm node, the computer device determines the relative distances between the node 2 and the nodes 3 and 4, respectively; wherein, the relative distance between the node 2 and the node 3 is 1, and since the relative distance between the node 2 and the node 3 satisfies the set value, in this case, the computer device determines that the pointing relationship between the node 2 and the node 3 is: node 2 points to node 3; in addition, the relative distance between the node 2 and the node 4 is-1, and since the relative distance between the node 2 and the node 4 satisfies the set value, in this case, the computer device determines that the pointing relationship between the node 2 and the node 4 is that the node 4 points to the node 2, so that the pointing relationships pointed by the three alarm nodes can be determined as follows: alarm node 4 → alarm node 2 → alarm node 3.
In a possible implementation manner, the implementation process of obtaining the pointing relationship of each alarm node in the second association topology may further include: determining a relative distance between the reference node and each alarm node contained in the second associated topological graph; the reference alarm node is any one of at least one alarm node; and then, under the condition that the relative distance meets a set value, determining the direction relation between the alarm nodes according to the relative distance. And under the condition that the relative distance does not meet the set value, updating the reference alarm node, wherein the updated reference alarm node is any one of the alarm nodes of which the pointing relationship is not determined in the second associated topological graph, namely, the relative distance between the reference node and each alarm node contained in the second associated topological graph is determined through iterative execution, and under the condition that the relative distance meets the set value, the pointing relationship between the alarm nodes is determined according to the relative distance. Here, the set value may be 1 or-1.
Taking the second associated topological graph shown in fig. 3B as an example, taking the node 4 as a reference alarm node, and the computer device determines the relative distances between the node 4 and the nodes 2 and 3, respectively; wherein, the relative distance between the node 4 and the node 2 is 1, and since the relative distance between the node 4 and the node 2 satisfies the set value, in this case, the computer device determines that the pointing relationship between the node 4 and the node 2 is: node 4 points to node 2; in addition, the relative distance between the node 4 and the node 3 is 2, and since the relative distance between the node 4 and the node 3 does not satisfy the set value, in this case, the computer device selects the warning node 3 as the next reference warning node, it can be understood that the warning node 3 is a warning node in the second association topology map for which no direction relationship is determined. Wherein, the relative distance between the node 3 and the node 2 is-1, and since the relative distance between the node 3 and the node 2 satisfies the set value, in this case, the computer device determines that the pointing relationship between the node 3 and the node 2 is: node 2 points to node 3. In summary, it can be determined that the pointing relationships pointed to by the three alarm nodes are as follows: alarm node 4 → alarm node 2 → alarm node 3.
And step S304, determining a root cause alarm node in the at least one alarm node according to the pointing relationship. In this embodiment of the present application, the implementation process of determining a root cause alarm node in at least one alarm node according to the direction relationship may include: and sequentially acquiring the last alarm node on each alarm chain according to the direction relation, and determining the last alarm node on each alarm chain as the root cause alarm node.
In a possible implementation manner, under the condition that the second associated topological graph contains a single alarm chain, sequentially excluding target alarm nodes according to the direction relation until the excluded target alarm node is the last alarm node in the second associated topological graph, and determining the last alarm node in the second associated topological graph as the root cause alarm node.
Taking the second association topological graph shown in fig. 3B as an example, the second association topological graph includes a single alarm chain, where the direction relationship between each alarm node in the alarm chain is: alarm node 4 → alarm node 2 → alarm node 3. In this case, the computer device excludes the alarm node 4, the alarm node 2, and the alarm node 3 in sequence until the excluded alarm node 3 is the last alarm node in the second associated topological graph, and at this time, determines the alarm node 3 as the root cause alarm node. In the implementation mode, the alarm phenomenon caused by the node in the second associated topological graph is eliminated by eliminating the target alarm node, so that the root cause alarm node can be quickly positioned, and the acquisition efficiency of the root cause alarm is improved.
In a possible implementation manner, under the condition that the second associated topological graph includes a plurality of alarm chains, the last alarm node on each alarm chain is sequentially obtained according to the direction relation, and the last alarm node on each alarm chain is determined as the root cause alarm node. Taking the second association topological graph shown in fig. 3C as an example, the second association topological graph includes two alarm chains, where the direction relationship between each alarm node in the alarm chain 1 is: alarm node 4 → alarm node 2 → alarm node 3 → alarm node 5; the pointing relationship between each alarm node in the alarm chain 2 is as follows: alarm node 4 → alarm node 2 → alarm node 1. In this case, the computer device sequentially obtains the last alarm node in each alarm chain according to the direction relationship, where the last alarm node in the alarm chain 1 is the alarm node 5, and the last alarm node in the alarm chain 2 is the alarm node 1, and then the computer device determines the alarm node 5 and the alarm node 1 as root cause alarm nodes. It can be understood that, in the case that the determined root cause alarm nodes are different on each alarm chain, a plurality of root cause alarm nodes are represented.
In a possible implementation manner, under the condition that the second associated topological graph includes a plurality of alarm chains, the last alarm node on each alarm chain is sequentially obtained according to the direction relation, and the last alarm node on each alarm chain is determined as the root cause alarm node. Taking the second association topological graph shown in fig. 3D as an example, the second association topological graph includes two alarm chains, where the pointing relationship between each alarm node in the alarm chain 1 is: alarm node 4 → alarm node 2 → alarm node 3 → alarm node 5; the pointing relationship between each alarm node in the alarm chain 2 is as follows: alarm node 4 → alarm node 2 → alarm node 1 → alarm node 5. In this case, the computer device sequentially obtains the last alarm node on each alarm chain according to the direction relationship, where the last alarm node in the alarm chain 1 is the alarm node 5, and the last alarm node in the alarm chain 2 is the alarm node 5, and then the computer device determines the alarm node 5 as the root cause alarm node. It can be understood that, in the case that the determined root cause alarm nodes are the same on each alarm chain, only one root cause alarm node is indicated.
In order to facilitate better understanding of the technical solutions described in the present application, the following description is made with reference to specific examples:
(1) example one
As shown in fig. 3E, the second association topological graph is formed by a plurality of alarm nodes extracted from the first association topological graph by the computer device according to the alarm information reported by the node. Fig. 3E includes three alarm sets, where alarm set 1 is composed of server a, application 2, application 3, and application 4; the alarm set 2 is composed of a server B and an application 7; the alarm set 3 is formed by an application 5. In the figure, the dotted line represents no association relationship between two alarm entities, and the solid line represents association relationship between two alarm entities. Taking the alarm set 1 as an example, the second associated topological graph corresponding to the alarm set includes two alarm chains, where the direction relationship between each alarm node in the alarm chain is: application 4 → application 2 → application 3 → server a; the pointing relationship between each alarm node in the alarm chain 2 is as follows: application 4 → application 2 → server A. In this case, the computer device sequentially obtains the last alarm node on each alarm chain according to the direction relationship, where the last alarm node in the alarm chain 1 is the server a, and the last alarm node in the alarm chain 2 is the server a, and then the computer device determines the server a as the root cause alarm node. It will thus be appreciated that the alarm generated by server a may trigger an alarm to occur at application 2 and may in turn trigger an alarm to occur at application 4.
(2) Example two
As shown in fig. 3F, the alarm information is extracted from the first association topology graph according to the alarm information reported by the node, and the second association topology graph is formed by a plurality of alarm nodes. As can be appreciated from fig. 3F, the relationship between the three is layer-by-layer dependent from the bottommost system to the topmost application, with a pointing relationship on attribution. Taking the alarm chain application A, mysql (relational database management system), system as an example, the pointing relationship between each alarm node in the alarm chain can be determined: application A → mysql → System. In this case, the computer device obtains the last alarm node in the alarm chain according to the direction relationship, and determines the system as the root cause alarm node. Therefore, the alarm generated by the insufficient memory of the system can trigger mysql to generate an alarm, and further trigger the application A to generate an alarm.
According to the alarm analysis method provided by the embodiment of the application, the computer equipment can obtain the second associated topological graph formed by at least one alarm node according to the first associated topological graph, and then obtain the direction relation of each alarm node in the second associated topological graph, so that the root cause alarm node can be determined according to the direction relation.
In addition, it should be noted that, in the embodiment of the present application, the reason for acquiring the root cause alarm node based on the second associated topological graph rather than the first associated topological graph is as follows: the first association topological graph only describes the association relation among a plurality of entities, but not comprises the distance relation among the entity characterizing the alarm. Moreover, the structure of the first association topological graph is too complex to be able to quickly locate the root cause alarm node compared with the structure of the second association topological graph.
In a possible implementation manner, after the computer device determines the root cause alarm node in the at least one alarm node, the computer device may output prompt information of the root cause alarm node to prompt an operation and maintenance person to repair the root cause alarm node. In this embodiment of the present application, outputting the prompt information of the root cause alarm node may include the following several implementation manners: (1) displaying a root cause alarm node through a display screen of the computer equipment; (2) and the computer equipment feeds back the information to the operation and maintenance personnel in a voice broadcasting mode so as to prompt the operation and maintenance personnel to repair the root cause alarm node.
In a possible implementation manner, the computer device may determine a target node corresponding to a root cause alarm based on similarities between associated topological graphs corresponding to different preset time ranges, specifically, the computer device obtains alarm information reported by at least one alarm node in a current preset time range, then constructs an associated topological graph formed by at least one alarm node in the current preset time range based on the first associated topological graph, and calculates, for example, by using Apriori algorithm, a similarity between an associated topological graph corresponding to alarm history information generated in a previous preset time range and an associated topological graph corresponding to alarm information generated in the current preset time range, where the similarity between the associated topological graph corresponding to alarm information generated in the current preset time range and the associated topological graph corresponding to alarm history information generated in the previous preset time range is greater than a preset threshold (for example, the preset threshold value is 0.9), the root cause alarm node in the last preset time range is determined as the root cause alarm node in the current preset time range. In this implementation manner, in consideration of the fact that in practical application, an alarm event has certain regularity, a root cause alarm node is determined to be generated according to the similarity between corresponding second associated topological graphs in adjacent preset time ranges, and the obtaining efficiency of the root cause alarm can be improved.
In summary, the root cause alarm analysis method provided in the embodiment of the present application directly performs root cause analysis in combination with the associated topological graph to determine the target node corresponding to the root cause alarm, without performing analysis in a series of disordered data, so that operation and maintenance personnel can perform root cause analysis at the fastest speed, and the problem that the root cause alarm cannot be processed in time when an alarm tide occurs is effectively avoided.
