Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
Fig. 1 is a flowchart illustrating a method for monitoring connectivity of a network card according to an embodiment of the present invention, as shown in fig. 1, the method is executed by a host in a virtualization management system, where the virtualization management system includes at least one host, and each host is configured with an arbitration IP. Before describing the specific method embodiment of this embodiment, some preparation operations will be described first, specifically referring to the following:
firstly, a management network arbitration IP needs to be configured, and before configuration, connectivity between a network card corresponding to each host in the management network and the arbitration IP is detected to ensure that the network card can establish communication connection with the arbitration IP under a normal condition, and the communication state after the communication connection meets the preset communication requirement. Only in this case, the state of the communication connection between the arbitration IP and the network card can be subsequently used to verify whether the network card is abnormal, for example, virtual connection, failure, or connectivity problems exist. After determining that the connectivity between the network card corresponding to the host in the management network and the arbitration IP is good, the following operations are performed.
Specifically, the method comprises the following steps:
Specifically, when the host in the management network in the virtualization management system has problems of poor connectivity of the main network card, virtual connection of the network card, and the like, the network card may not automatically switch the main network card and the standby network card. The situation will inevitably affect that the service on the system cannot run normally, and the network card is not easy to find out by people (because the network card is in a display or connection state, the reason of the problem is difficult to find out) if the network card has the problem, and the user only knows that the system has the problem when finding that the service is abnormal. But now it is too late, which has already caused an inevitable impact on the user's traffic.
Therefore, in this embodiment, the communication status between the primary network card on the host and the management network arbitration IP is monitored.
Optionally, when detecting the communication state between the main network card on the host and the management network arbitration IP, the following method may be specifically implemented, specifically referring to fig. 2. Fig. 2 illustrates a specific implementation manner, which specifically includes:
In an optional example, when it is determined that the packet loss rate of the test packet received by the management network arbitration IP is less than or equal to the preset threshold, it is determined that the communication state between the main network card and the management network arbitration IP meets the preset communication requirement, otherwise, it is determined that the communication state between the main network card and the management network arbitration IP does not meet the preset communication requirement.
Specifically, it is beneficial to send a test message to the management network arbitration IP through the master network card every 20 seconds, and in a specific example, the test message may be a ping packet, or the test message may be a UDP message, and of course, it may also be other test message packets, and what is specifically the case. Preferably, in this embodiment, a ping packet is used.
Then, according to the packet loss rate of the test message received by the arbitration IP of the management network,
for example, in every 10 ping packets, the packet loss is 2, and the packet loss rate is 20%. In a specific example, if the packet loss rate of the test packet received by the management network arbitration IP is lower than or equal to 20%, it indicates that the communication state between the main network card and the management network arbitration IP meets the preset communication requirement, and otherwise, it indicates that the communication state does not meet the preset communication requirement.
Of course, the upper limit 20% set in the above example is only a specific example, and does not represent a specific limited value in practical application, and the upper limit of the specific packet loss rate can be set completely according to practical situations, which is not described in detail herein.
And step 120, when the communication state between the main network card and the arbitration IP of the management network is determined not to meet the preset communication requirement, inquiring the communication state between the standby network card on the host and the arbitration IP of the management network.
And step 130, when the communication state between the standby network card and the arbitration IP of the management network is determined to meet the preset communication requirement, controlling the standby network card to serve as the main network card for executing the business operation corresponding to the main network card.
Specifically, as described above, when the communication state between the main network card and the arbitration IP of the management network does not meet the preset communication requirement, the main network card is inevitably switched to the standby network card whose current communication state meets the preset communication requirement. That is, the standby network card meeting the preset communication requirement is controlled to be used as the main network card, and the subsequent operation is executed. Therefore, the communication status between the standby network card on the host and the management network arbitration IP needs to be queried.
And when the communication state between the standby network card and the arbitration IP of the management network is determined to meet the preset communication requirement, controlling the standby network card to serve as the main network card for executing the business operation corresponding to the main network card.
Specifically, whether the communication state between the standby network card and the arbitration IP of the management network meets the preset communication requirement or not may also be queried by the operation steps from step 210 to step 220. After sending a ping packet to the management network arbitration IP through the standby network card, inquiring the packet loss rate of the test message received by the management network arbitration IP, and determining the communication state between the standby network card and the management network arbitration IP.
Further optionally, as described above, after the standby network card is switched to the main network card, the method further includes: and switching the main network card with the communication state not meeting the preset communication requirement into a standby network card.
The method for monitoring the connectivity of the network card provided by the embodiment of the invention monitors the communication state between the main network card on the host and the arbitration IP of the management network, and inquires the communication state between the standby network card on the host and the arbitration IP of the management network when the communication state is determined to be not in accordance with the preset communication requirement. And when the communication state between the standby network card and the arbitration IP of the management network is determined to meet the preset communication requirement, controlling the standby network card to serve as the main network card for executing the business operation corresponding to the main network card. By the method, the state of the main network card on the host can be known in a monitoring mode, and once the main network card is determined to have problems, such as failure and network instability, the main network card can be switched to the standby network card in time, so that the service running in the system is not affected, the reliability of service running is ensured, and the extra load of the network card cannot be increased.
Optionally, on the basis of the foregoing embodiment, another method for monitoring connectivity of a network card is provided in the embodiments of the present invention, and the content of the method is the same as or similar to that in the foregoing embodiments, and is not described herein again. In this section, it will be described that when the spare network card does not include only one spare network card, but includes a plurality of spare network cards, the method may further include the following method steps, which are specifically shown in fig. 3:
Specifically, when a plurality of standby network cards are included, one standby network card can be randomly selected from the standby network cards, that is, the first standby network card sends a test message to the arbitration IP of the management network. And then verifying whether the network communication state between the first standby network card and the arbitration IP of the management network meets the preset communication requirement.
And step 320, controlling the first standby network card to be a main network card when the communication state between the first standby network card and the arbitration IP of the management network is determined to meet the preset communication requirement according to the packet loss rate of the test message received by the arbitration IP of the management network.
The specific implementation processes of step 310 and step 320 refer to the above embodiment, and are not described herein again.
And step 330, when the communication state between the first standby network card and the arbitration IP of the management network is determined to be not in accordance with the preset communication requirement according to the packet loss rate of the test message received by the arbitration IP of the management network, continuing to select the next standby network card to send the test message to the arbitration IP of the management network.
And verifying whether the communication state of the next standby network card arbitrating the IP from the management network meets the preset communication requirement.
In a specific example, when it is determined that the packet loss rate of the test packet received by the management network arbitration IP is less than or equal to the preset threshold, it is determined that the communication state between the standby network card and the management network arbitration IP meets the preset communication requirement, otherwise, it is determined that the communication state between the standby network card and the management network arbitration IP does not meet the preset communication requirement.
The specific process of sending the test message, the preset threshold corresponding to the packet loss rate of the test message received by the management network arbitration IP, and the specific evaluation of whether the communication state between the standby network card and the management network arbitration IP meets the preset communication requirement, etc., may refer to the process of evaluating whether the communication state between the main network card and the management network arbitration IP meets the preset communication requirement, and will not be described herein again.
And 340, controlling a second standby network card to be a main network card until the communication state between the second standby network card in the plurality of standby network cards and the arbitration IP of the management network is determined to meet the preset communication requirement.
Of course, if the selection is not random, other manners may also be adopted, for example, numbering all the standby network cards, then preferentially selecting one standby network card according to the numbering sequence, then performing the operations of step 310 to step 320, and if the communication state between the first standby network card and the arbitration IP of the management network does not meet the preset communication requirement, continuing to select the next standby network card according to the numbering sequence, that is, performing the operation of step 330. After selecting a standby network card again, the operation of step 320 is executed repeatedly to verify whether the communication state between the next standby network card and the arbitration IP of the management network meets the preset communication requirement. And controlling the second standby network card to be the main network card until any standby network card, such as a second standby network card, is selected from the plurality of standby network cards and the communication state between the standby network card and the arbitration IP of the management network meets the preset communication requirement.
By the method, the service running in the system can be further ensured not to be influenced, the service in the system can run normally, and the extra load of the network card cannot be increased.
In the above, it is assumed that, in the current query process, a situation that a communication state between a certain standby network card and the arbitration IP of the management network meets the preset communication requirement can be queried in the standby network card.
In consideration of the above, during the execution process, it may be that the appropriate standby network card cannot be queried in the query, so as to ensure that the communication state between the network card and the arbitration IP of the management network meets the preset communication requirement. In this case, the method may further include the following method steps, specifically referring to fig. 4, where fig. 4 is another method for monitoring connectivity of a network card provided in the embodiment of the present invention, and the content of the method is the same as or similar to that in the above embodiment, and is not described here again.
And step 410, polling to use a network card on the host as a primary master network card at preset time intervals, and monitoring the communication state between the current master network card and the arbitration IP of the management network.
And step 420, until the communication state between one of the network cards on the host and the arbitration IP of the management network is determined to meet the preset communication requirement.
Alternatively, the first and second electrodes may be,
Specifically, if the difference queries each backup network card, it is not found that the communication state between the backup network card and the arbitration IP of the management network meets the preset communication requirement (for simplicity and convenience of description, it is simply stated that the backup network card does not meet the preset requirement hereinafter). Then, at this time, instead of distinguishing the main network card from the standby network card, each network card is used as a primary main network card, and then whether the communication state between the current main network card on the host and the arbitration IP of the management network meets the preset communication requirement is determined, and if not, after the interval of the preset time, whether the communication state between the next main network card and the arbitration IP of the management network meets the preset requirement is inquired again.
And when the communication state between one network card in the host and the arbitration IP of the management network is determined to meet the preset communication requirement, taking the network card as a main network card, and then executing subsequent operation tasks.
Or, all the network cards are used as the main network card, and the communication state between the main network card and the management network arbitration IP is inquired as one polling, for example, twice after the iterative polling is carried out for many times. And if the proper network card is not found as the main network card, ending the operation and informing the worker of the abnormal situation of the network card so that the worker can replace the network card in time.
Optionally, after each polling, the interval time may be increased according to a preset rule. For example, the first poll may be 20 seconds apart, the second poll may be 40 seconds apart, the third poll may be 60 seconds apart, and so on. However, the interval time cannot exceed 320 seconds at maximum.
Optionally, when the communication state between the network card and the management network arbitration IP is still not found to meet the preset communication requirement after polling for the preset number of times, the method further includes: the delete management network arbitrates the IP.
The reason is that if no network card can be found as the current main network card after polling for many times, it indicates that all network cards have failed, and the existence of the arbitration IP has no meaning any more, so in order to release the memory space and save the system resources, the arbitration IP of the management network can be deleted.
FIG. 5 illustrates an overall workflow architecture diagram for monitoring network card connectivity using arbitrated IP, comprising:
initially, the state before the management network arbitrates the IP is configured, and mainly, the application environment before the arbitrated IP is installed is configured.
Checking, namely detecting the connectivity between the management network and the arbitration IP, sending 10 ping packets at intervals of 2s, and if the packet loss is more than or equal to 2, indicating that the communication state between the main network card and the arbitration IP does not meet the preset communication requirement, or the connectivity is not good;
polling, switching the uplink network card and checking connectivity;
ending, deleting the arbitration IP.
The detailed operation steps may include:
a: configuring a management network arbitration IP, and checking the connectivity between the management network and the arbitration IP before configuration;
b: the connectivity between the management network and the arbitration IP is good, and the network is checked again after 20 s;
c: the connectivity between the management network and the arbitration IP is not good;
d: the uplink is switched (other standby network cards are switched), and the connectivity between the management network and the arbitration IP is good;
e: after the uplink of the management network is switched once and the IP is not communicated with the network, performing a second attempt, namely taking each network card of all the network cards of the uplink of the management network as a main network card, and verifying the connectivity once again;
f: the uplink network card is switched for 2 times (assuming that the preset times are 2 times) and is not communicated with the arbitration IP, and then the switching is stopped;
g: the arbitrated IP is manually deleted, or the management network uplink is changed from multi-block network cards to one block.
The purpose of changing from a plurality of network cards to one network card is also to save system resources and prevent operations such as arbitrating IP polling to search for a proper network card. Equivalent to the role of deleting arbitration IPs.
The above processes are all described in detail above, and therefore are not described in detail here.
