In addition, the embodiments and features of the embodiments of the present invention may be combined with each other without conflict
Example one
The embodiment of the invention provides a method for detecting the state of a component in a cluster. The method may be performed by a state detection apparatus of a component in a cluster, which may be implemented by software and/or hardware, and may be generally integrated in a state detection system of a component in a cluster. Fig. 1 is a schematic flowchart of a method for detecting a state of a component in a cluster according to an embodiment of the present invention, where as shown in fig. 1, the method includes:
s110, the main monitoring tool obtains the component identification of the component to be monitored in the cluster.
In this step, the master monitoring tool may obtain the component identification of the component to be monitored from the central component of the cluster, the component to be monitored, or from the monitoring tool. The master monitoring tool may be specifically understood as a program for monitoring a component to be monitored in a cluster, and may be installed on a monitoring device, where the monitoring device may be a node in the cluster (i.e., a device in the cluster) or may be another device independent of the cluster. The component to be monitored can be understood as a component to be monitored in the cluster, the component may specifically be a program installed on each node in the cluster, and the component to be monitored of the cluster may include all or part of the components in the cluster, that is, the main monitoring tool may monitor the operating states of all the components in the cluster, or may monitor only the operating states of part of the components marked as the component to be monitored in the cluster, and may specifically be set by a worker. The component identifier of the component to be monitored may be specifically understood as identification information capable of uniquely determining the component to be monitored, and may be a process ID of an operating process of an operating system corresponding to the component to be monitored, or a service name of a service provided by the component to be monitored, and the like, which is not limited in this embodiment.
For example, after the component to be monitored in the cluster is started, the component identifier of the component to be monitored can be actively sent to the central component in the cluster; the central component receives and records the component identifier sent by the component to be monitored, and actively sends the component identifier to the main monitoring tool, or the main monitoring tool sends an identifier query request to the central component, and the central component sends the component identifier of the component to be monitored to the main monitoring tool after receiving the identifier query request sent by the main monitoring tool. Or after the component to be monitored is started, the IP address of the monitoring device provided with the main monitoring tool can be acquired, and the component to be monitored actively sends the component identifier of the component to the main monitoring device by communicating with the monitoring device according to the IP address. Or, the slave monitoring tool may periodically detect whether a new component to be monitored is started on the node, and when detecting that a new node to be monitored is started on the node, obtain a component identifier of the newly started component to be monitored, and send the component identifier to the master monitoring tool according to the IP address of the monitoring device.
And S120, the master monitoring tool controls a slave monitoring tool to detect the running state of the component to be monitored based on the component identifier, and the slave monitoring tool and the component to be monitored are installed in the same node of the cluster.
In this embodiment, the slave monitoring tool may specifically be understood as a program for detecting an operating state of a component to be monitored on the node, and may be an auxiliary tool corresponding to the master monitoring tool, or may also be a third-party tool installed on the node, that is, in this embodiment, the master monitoring tool may detect the operating state of the component to be monitored through the auxiliary tool corresponding to the master monitoring tool, and may also be compatible with other third-party tools having a monitoring function, and detect the operating state of the component to be monitored by calling the third-party tool installed on the node and having the monitoring function.
For example, when the operating state of the component to be monitored needs to be detected, the master monitoring tool may generate a state detection instruction carrying a component identifier of the component to be monitored, whose operating state needs to be detected at this time, for indicating the detection of the slave monitoring tool or periodically detecting the operating state of the component to be monitored, and send the state detection instruction to the slave monitoring tool; correspondingly, the slave monitoring tool determines the component to be monitored, which needs to detect the running state of the component, in the installed node according to the component identifier carried in the state detection instruction, detects the running state of the component to be monitored, namely, obtains the running state information of the component to be monitored, and sends the running state information to the master monitoring tool, so that the master monitoring tool can determine the running state of the component to be monitored according to the running state information sent by the slave monitoring tool. Wherein the slave monitoring tool can be installed on each node of the cluster; the operation state information may include a performance index of the component to be monitored and/or state information of the component to be monitored, the performance index may include a CPU, a memory, and/or a disk and the like occupied by the component to be monitored, and the state information includes start-up and shut-down of the component to be monitored.
In a preferred implementation manner of this embodiment, after the master monitoring tool controls the slave monitoring tool to detect the operating state of the component to be monitored based on the component identifier, the method further includes: and the main monitoring tool controls the component to be monitored according to the running state. Specifically, after determining the running state of the component to be monitored, the main monitoring tool can further control the component to be monitored according to the running state of the component to be monitored, and if the running state of the component to be monitored is an abnormal state, the main monitoring tool gives an alarm and closes the component to be monitored; for another example, whether each performance index of the component to be monitored is within a normal range is determined, and when it is determined that the performance index is not within the normal range, the component to be monitored is correspondingly controlled, for example, when the component occupies too much certain resource (such as a CPU, a memory, or a disk) and the utilization rate of the resource reaches a maximum utilization rate threshold, the occupation of the component to be monitored on the corresponding resource is reduced or the unimportant component to be monitored is closed, or when the component to be monitored is already in a closed state, the occupation of each of the above resources by the component to be monitored is released, and the like, which can be specifically set according to needs.
In the method for detecting the state of the component in the cluster provided by the embodiment of the invention, the master monitoring tool acquires the component identifier of the component to be monitored in the cluster, and controls the slave monitoring tool to detect the running state of the component to be monitored according to the component identifier. By adopting the technical scheme, the operation state of the component to be monitored is detected by the slave monitoring tool which is installed in the same node with the component to be monitored, the operation state of the component to be monitored does not need to be detected by the component to be monitored, the burden of the component to be monitored can be reduced, the operation speed of the component to be monitored is increased, the response speed of the component to be monitored is increased, and the waiting time of a user is shortened.
Example two
Fig. 2 is a schematic flowchart of a cluster gradual state detection method according to a second embodiment of the present invention. On the basis of the foregoing embodiment, this embodiment optimizes "the main monitoring tool obtains the component identifier of the component to be monitored in the cluster" to: the main monitoring tool sends an identification query request to a central component of the cluster; and when receiving the identifier query request, the central component acquires the component identifier of the component to be monitored, which is stored in the central node provided with the central component, and sends the component identifier to the main monitoring tool, so that the main monitoring tool receives the component identifier.
Further, the method for detecting the state of the component in the cluster provided by this embodiment further includes: after the components to be monitored in the cluster are started, the component identifiers of the components are obtained and sent to the central component for storage.
Further, "the master monitoring tool controls the slave monitoring tool to detect the operating state of the component to be monitored based on the component identifier" may be optimized to "the master monitoring tool determines, according to the component identifier, an IP address of a node to be monitored on which the component to be monitored is installed, and sends a state detection instruction to the slave monitoring tool installed on the node to be monitored based on the IP address, where the state detection instruction carries the component identifier; the slave monitoring tool acquires the running state information of the component to be monitored according to the component identifier and sends the running state information to the master monitoring tool, so that the master monitoring tool determines the running state of the component to be monitored "
Correspondingly, as shown in fig. 2, the method for detecting the state of the component in the cluster provided by this embodiment includes:
s210, after the components to be monitored in the cluster are started, the component identifiers of the components are obtained and sent to the central component for storage.
In this embodiment, taking the component identifier of the component to be monitored as the process ID of the process run by the operating system corresponding to the component to be monitored as an example, after the component to be monitored in the cluster is started, the process corresponding to the component to be monitored may be first located according to the correspondence between each component and each process recorded in the node to be monitored where the component to be monitored is installed, and the process ID of the process is obtained as the component identifier of the process itself; then, according to the IP address of the central node and/or the identification of the central component, which is recorded in the cluster of the nodes to be monitored, of the central component, the communication connection is established with the central component on the central node, and the identification of the central component is sent to the central component based on the communication connection. Therefore, after receiving the component identifier sent by the component to be monitored, the central component can store the component identifier in the central node so as to be acquired by the main monitoring tool.
S220, the main monitoring tool sends an identification query request to the central component of the cluster.
And S230, when receiving the identifier query request, the central component acquires the component identifier of the component to be monitored, which is stored in the central node provided with the central component, and sends the component identifier to the main monitoring tool, so that the main monitoring tool receives the component identifier.
For example, the monitoring device installed with the main monitoring tool may locally store an IP address of a central node in the cluster, and when the main monitoring tool needs to detect the operating state of the component to be monitored, the main monitoring tool generates an identifier query request, establishes communication connection with the central node according to the IP address of the central node, and sends the generated identifier query request to the central node; correspondingly, after receiving the identifier query request sent by the main monitoring tool, the central component can acquire the component identifier of each component to be monitored, which is stored in the central node, generate response information carrying the component identifier of each component to be monitored, and send the response information to the main monitoring tool through the communication connection established between the central component and the monitoring equipment; therefore, the main monitoring tool analyzes the received response information, and the component identification of the component to be monitored in the cluster can be obtained. The identification query request can be used for acquiring the component identifications of all components to be monitored in the cluster.
S240, the main monitoring tool determines the IP address of the node to be monitored, on which the component to be monitored is installed, according to the component identifier, and sends a state detection instruction to a secondary monitoring tool installed on the node to be monitored based on the IP address, wherein the state detection instruction carries the component identifier.
And S250, the slave monitoring tool acquires the running state information of the component to be monitored according to the component identifier and sends the running state information to the main monitoring tool, so that the main monitoring tool determines the running state of the component to be monitored.
Illustratively, a master monitoring tool acquires an IP address of a node to be monitored, on which a component to be monitored is installed, according to a component identifier of the component to be monitored, establishes communication connection with the node to be monitored according to the IP address of the node to be monitored, generates a state detection instruction carrying the component identifier of the component to be monitored, and sends the state detection instruction to a slave monitoring tool installed on the node to be monitored through the established communication connection; correspondingly, after receiving the state detection instruction sent by the master monitoring tool, the slave monitoring tool analyzes the received state detection instruction to obtain the component identifier of the component to be monitored, obtains the running state information of the component to be monitored corresponding to the component identifier, and sends the obtained running state information to the master monitoring tool through the established communication connection, so that the master monitoring tool determines the running state of the component to be monitored according to the running state information sent by the slave monitoring tool.
The method for acquiring the running state information of the component to be monitored can be selected as required, for example, the slave monitoring tool can firstly determine the process ID of the process corresponding to the component to be monitored in the operating system of the node to be monitored according to the component identifier of the component to be monitored, and then query the process information of the process corresponding to the component to be monitored by using the process monitoring command of the operating system of the node to be monitored, such as the ps command of the linux system, so as to obtain the running state information of the monitoring component.
Taking a third-party tool installed in each node of the cluster as a slave monitoring tool as an example, please refer to fig. 3 (only one component to be monitored on a node to be monitored is shown in the figure), a data flow process of the method for detecting the state of the component in the cluster provided in this embodiment may be: when the component to be monitored is started, positioning the process corresponding to the operating system, and sending the process identifier of the process as the component identifier of the process to the central component for storage; the main monitoring tool queries the component identifier of the component to be monitored in the cluster through the central component, namely the central component sends the component identifier of the component to be monitored, which is stored in the central node, to the main monitoring tool when the main monitoring tool queries the identifier; when the main monitoring tool needs to detect the running state of the component to be monitored, the main monitoring tool sends the component identification of the component to be monitored to a third-party tool; correspondingly, after receiving the component identifier sent by the main monitoring tool, the third-party tool acquires the running state information of the component to be monitored corresponding to the received component identifier, and sends the running state information to the main monitoring tool.
In the method for detecting the state of the component in the cluster provided by the second embodiment of the present invention, after the component to be monitored in the cluster is started, the component identifier of the component to be monitored is obtained and sent to the central component for storage; the main monitoring tool sends an identification query request to the central component; when receiving an identification query request sent by a main monitoring tool, the central component sends a stored component identification of the component to be monitored to the main monitoring tool; the method comprises the steps that a main monitoring tool determines the IP address of a node to be monitored, which is provided with a component to be monitored, according to a component identifier of the component to be monitored, and sends a state detection instruction carrying the component identifier of the component to be monitored to a secondary monitoring tool on the node to be monitored based on the IP address; and the slave monitoring tool on the equipment to be monitored acquires the running state information of the component to be monitored according to the component identifier carried in the state detection instruction, and sends the running state information to the master monitoring tool. By adopting the technical scheme, the component identifier of the component to be monitored is sent to the central node when the component to be monitored is started, so that the main monitoring tool can accurately position the component to be monitored without inputting information such as the operation mode, the operation parameters and the like of the component to be monitored by a user, manpower consumed in the component state detection process in a cluster can be reduced, and the state detection speed of the component to be monitored is further improved.
