Detailed Description
Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and together with the description serve to explain the principles of the invention, and are not intended to limit the scope of the invention.
Distributed systems have become the core underlying framework for current cloud computing, cloud storage, intelligent computing centers. Based on Hadoop, spark and other distributed storage and computing frameworks, the system can integrate multiple traditional complex tasks such as network transmission, load balancing, AI processing and the like, and the bottom layer design of the system is comprehensive and has much more complexity than various prior distributed systems.
Visual monitoring of distributed systems is an important study of current distributed system management. At present, the visual monitoring of the distributed system mainly adopts the mode of establishing 3-5-dimensional visual charts such as a ring chart, a line chart, a column chart, a bubble chart and the like to display monitoring information, and the visual monitoring mode adopting the multi-chart mode can fracture the whole running state, so that not only is the single chart information provided incompletely, but also other parts can be ignored when a user observes 1 chart, and the system is not regulated timely in case of abnormal conditions, thereby causing serious consequences.
Based on the above, a specific embodiment of the application discloses a visual monitoring method of a distributed system, which adopts a fractal graph to integrally display monitoring information of the distributed system in a graph, so that not only can the subordinate relations among nodes be displayed, but also the running state of each node of the distributed system can be comprehensively displayed, the monitoring personnel can monitor the system conveniently, and abnormal states of the system can be found in time. As shown in fig. 1, the method comprises the steps of:
s1, acquiring a node level of the distributed system according to a node routing table of the distributed system, and representing a node level structure of the distributed system by adopting a regular polygon fractal graph, wherein one sub-fractal graph in the fractal graph corresponds to one node of the distributed system, and each sub-fractal graph is drawn by adopting a dotted line.
The distributed system generally adopts a master-slave structure, which may be a two-hierarchy structure or a multi-hierarchy structure, and the master node of the distributed system maintains the information of the lower slave node, so that the information of the lower slave node is acquired according to the routing information table of the master node, and the node hierarchy structure of the whole distributed system is acquired.
The part of the fractal pattern has a certain degree of similarity to its whole, i.e. the parent image is structurally similar to the child image, but the child image is part of the parent image. In a recursive manner, the fractal graph can be theoretically drawn in an infinite hierarchy, and is therefore suitable for representing the node hierarchy of a distributed system. Each sub-fractal in the fractal graph corresponds to a node of the distributed system. The subsidiary level of the node can be clearly shown through the father-son fractal graph, each child is similar to the father graph in structure, the information dimension which can be displayed by each child is the same as that of the father graph, and as the child is a part of the father graph, all monitoring information can be displayed in one graph, so that the running state of the distributed system can be monitored integrally, and the problem of monitoring omission caused by the fact that the monitoring information is subjected to splitting display is avoided.
Specifically, the number of edges of the regular polygon is determined according to the monitored dimension. The monitoring dimension of the distributed system generally comprises CPU resources, memory resources, disk resources and GPU resources, and monitoring information which can be obtained by monitoring the resources comprises the occupancy rate of the resources and the state of the resources. The monitoring dimension may also include other dimensions, such as a network resource, a JVM resource, etc., and corresponding monitoring information is obtained according to the difference of the monitoring dimensions.
The main stream distributed system comprises a monitoring interface through which the monitoring information can be obtained. Such as the http monitor port of Hadoop or JMX port. Monitoring information, such as the ganlia tool, may also be obtained through a monitoring interface provided by a third party monitoring tool. And each side of the regular polygon corresponds to one monitoring dimension, and the acquired monitoring information can be displayed as the side line information of the regular polygon, so that the monitoring information of a plurality of dimensions is displayed in one graph.
Adopting a positive N-type polygon to represent the uppermost node of the node hierarchical structure to form a zero-order sub-fractal graph;
for each positive N-sided polygon in the j-1 th-order sub-fractal graph, obtaining the number M of sub-nodes of the node represented by the current positive N-sided polygon according to the node routing table, dividing an inscribed circle of the positive N-sided polygon into M sector areas by adopting dividing lines, drawing a circle by taking the middle point of each dividing line as the center of a circle and taking half of the dividing line as the diameter, and drawing the positive N-sided polygon in the circle to form a j-order sub-fractal graph; the circle is the inscribed circle of the positive N deformation;
the N value is determined according to the monitoring dimension of the distributed system, and T represents the node layer number of the distributed system; j=1, 2, … T-1.
By way of example, 4 monitoring dimensions are illustrated. Firstly, drawing a regular quadrangle on a monitoring interface, and representing the main node of the uppermost layer of the distributed system by the regular quadrangle to form a zero-order fractal graph. And recording the graph index of the regular quadrilateral graph and the node information corresponding to the graph index.
If the uppermost layer of the master nodes has 5 slave nodes, dividing an inscribed circle of a regular quadrangle of the zero-order fractal graph into 5 fan-shaped areas on average, drawing a small circle by taking the middle point of each dividing line as the center of a circle, taking half of the length of the dividing line as the diameter, drawing the regular quadrangle by taking the small circle as the inscribed circle, and forming a first-order fractal graph, wherein the small circle can be used as an circumscribed circle for drawing the regular quadrangle when the method is implemented. Each positive quadrangle of the first-order sub-fractal graph represents a slave node, and the graph index of each positive quadrangle and corresponding node information are recorded.
And by analogy with the steps, forming a fractal graph representing the static structure of the distributed system. The static structure is because, although a plurality of nodes are constructed in the distributed system, for each task, the task is split into a plurality of subtasks, the subtasks are distributed and run on different nodes, and for one distributed task, not all the nodes are running their subtasks, so in step S1, all the subtracts in the fractal graph are drawn as dotted lines, indicating the state that the node is not running the subtasks yet. And drawing the sub-graph corresponding to the node as a solid line after the subtasks are distributed in the node, so that the node task operation condition of the distributed system is clearly shown.
In implementation, the fractal graph may be drawn using an OpenGL or DirectX graphics API.
S2, acquiring subtask information and resource allocation information of a current task of the distributed system, acquiring operation nodes corresponding to operation resources of each subtask based on the subtask information and the resource allocation information, searching the operation nodes in the fractal graph, and drawing a sub-fractal graph corresponding to the operation nodes into a solid graph.
The distributed system divides a task into sub-tasks, the sub-tasks are distributed to run on different nodes according to a distribution scheduling strategy, and one sub-task may run on a plurality of nodes. The task scheduling management center of the distributed system maintains the partition information and the node allocation information of each task. For example, a certain subtask of a certain task runs on a certain node(s). Data for one subtask may be stored on one node, but computation may be performed on another node, i.e., two or more nodes cooperate to perform one subtask. When one task is operated, subtask information and node allocation information of the current task of the task scheduling management center are obtained, so that operation nodes corresponding to each subtask are obtained. Inquiring a sub-fractal graph corresponding to an operation node in the fractal graph according to the graph index and the node information, and drawing the sub-fractal graph into a solid line so as to represent that the operation task of the node is required. Therefore, monitoring staff can clearly and completely see which nodes in the system are running tasks, and the monitoring staff can monitor the nodes.
In implementation, the operation nodes corresponding to different subtasks can be filled with different colors, so that monitoring personnel can monitor conveniently, and the filling color is different from the color representing the monitoring information.
And S3, acquiring monitoring information of each operation node in real time, and drawing and displaying the monitoring information on the side line of the sub fractal graph corresponding to the operation node based on the monitoring information.
Specifically, the monitoring information of each operation node can be obtained through a monitoring interface or a third-party monitoring tool of the distributed system.
Searching a sub fractal graph corresponding to the operation node in the regular polygon fractal graph based on a graph index.
And taking the side length of the sub-fractal graph multiplied by the occupancy rate of the resource as the length of a monitoring information display line, taking the color corresponding to the state level of the resource as the color of the monitoring information display line, and drawing the monitoring information display line at the side line position of the sub-fractal graph corresponding to the resource.
Specifically, sub-fractal graph information corresponding to the operation node can be queried according to the graph index, for example, information such as vertex coordinates, side lengths and the like of the sub-fractal graph is obtained. For example, if the lowest edge of the quadrangle represents the disk resource, as shown in fig. 3, the side length of the sub fractal graph P1 is multiplied by the occupancy rate of the disk to be used as the length of the monitor information display line, the color corresponding to the status level of the disk is used as the color of the monitor information display line, and the status of the disk can be classified into different levels according to the actual monitoring requirement, for example, the status of the disk is classified into normal normal, warning, alert according to the number of bad tracks of the disk, and the status of the disk is respectively represented by green, yellow and red. The ratio of memory read/write rate to normal value determines the state level, which the GPU and CPU can determine in terms of the number of their queued (polling) processing tasks. For example, 10 threads are queued in the warn state, and more than 100 threads are queued in the alert state.
In implementation, the highest-level abnormality can also be expressed in a high-frequency flashing mode, the flashing frequency is the inverse of the time difference (in minutes) from the time of the primary signal to the current time, so that the longer the abnormality is, the higher the flashing frequency is, namely, a certain frequency is used for drawing the monitoring information display lines into different colors, thereby helping monitoring staff to find out abnormal information in time and further ensuring that the system can stably run.
If the node monitoring information in each subgroup needs to be checked, the local image can be amplified by mouse scrolling, so that the monitoring information can be checked conveniently.
Based on the fractal theory, when the node structure of the distributed system is infinitely expanded, the running states of the network structure, the working group and various resources of each working node can be displayed in one graph at the same time, and the monitoring capability of operators on the real-time state of the system is enhanced.
