Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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 application.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for monitoring an SAS port according to an embodiment of the present disclosure, where the method includes:
s101: reading a period change value in the current monitoring period of the SAS port;
the SAS port generally includes a plurality of PHYs, and the number of PHYs included in the SAS port in this embodiment is not particularly limited, and may be 4, 8, or another number. When the fixed PHY does not stably send and receive signals, the SAS chip automatically selects other PHYs for the port to be used for communication, and the PHY change count of the port is increased by 1. In other words, when the fixed PHY signal is unstable, the period change value is incremented by 1, and whether the PHY is a fixed PHY during communication through the SAS port specifically determines whether the signal is stable. Of course, the signal stability may also be determined according to real-time communication data during communication, and the period change value in the current monitoring period may be updated. Every time the SAS port communicates using a non-fixed PHY, the value of the cycle change is incremented by 1.
It is understood that the present embodiment generally requires port parameter initialization for the SAS port before executing the present step. The port parameters comprise a monitoring period, an alarm threshold value, an accumulated change value, a change value of a previous period and a change value of the current period. The monitoring period refers to a monitoring period of the SAS port, the accumulated change value and the change value of the current period are both 0 at the beginning, and the change value of the previous period is the change value of the current period in the previous monitoring period. It should be noted that, in this embodiment, neither the monitoring period nor the alarm threshold is specifically limited, and may be set by a person skilled in the art. For example, the monitoring period may be 1 minute or 2 minutes, etc.
S102: determining an accumulated change value according to the difference value of the change value of the period and the change value of the previous period;
before executing the step, the change value of the previous period needs to be acquired by default, specifically, the change value of the current period in each period can be recorded by using a storage structure such as a log, and the change value of the previous period can be read from the storage structure.
The step is to determine the accumulated change value, and obviously, if the SAS port is working normally, the change value of the previous cycle should be small, and if the difference between the change value of the cycle and the change value of the previous cycle is large, it indicates that the change value of the cycle is large, which means that the SAS port is communicating with a non-fixed PHY more, and there is a large probability of abnormality, at least, it indicates that the PHY is abnormal, resulting in unstable communication, and the SAS port is abnormal to the outside.
S103: judging whether the accumulated change value is larger than an alarm threshold value; if yes, entering S104;
s104: and taking the SAS port as a failure port.
The step aims to judge the size relation between the accumulated change value and the alarm threshold, if the accumulated change value is larger than the alarm threshold, the SAS is used as a fault port, the SAS port can be temporarily eliminated as a communication port, an alarm is reported to prompt that the communication risk exists in the SAS, and the normal communication function of the SAS is recovered after the SAS is repaired. Of course, if the value is smaller than the alarm threshold, it indicates that there is no abnormality in the SAS port, and the SAS port does not need to be processed, and the change value of the previous cycle may be updated by using the change value of the current cycle.
In particular, this embodiment may be repeatedly executed multiple times in one monitoring period, and corresponding steps are executed according to the read change value of this period each time.
It should be noted that, if an SAS port in a certain monitoring period is abnormal, the change value of the previous period in the period is not suitable for being used as the change value of the previous period in the next monitoring period, and when the SAS port is initialized before the next monitoring period starts, the change value of the previous period, the accumulated change value, and the change value of the current period may be initialized to 0, which does not affect the subsequent monitoring process.
In the embodiment of the application, the PHY change frequency of the SAS port is periodically acquired, the fault of the SAS port is predicted, and when the accumulated change value is larger than the alarm threshold value or not, the port is used as the fault port so as to be removed from the SAS port, and an alarm is reported to prompt risks.
Based on the foregoing embodiment, as a preferred embodiment, since the communication process is easily affected by external factors, for example, changes of communication objects, and the like, and thus the change value of the present period of each monitoring period is easily different, in order to reduce the influence of additional factors on the SAS port monitoring, before performing S103 to determine whether the accumulated change value is greater than the alarm threshold, the method may further include:
correcting the accumulated change value according to the magnitude relation between the accumulated change value and the alarm threshold value to obtain a corrected value;
it may be determined whether the correction value is greater than the warning threshold when S103 is executed.
At this time, the complete execution flow of the monitoring method for the SAS port provided in this embodiment is as follows:
s201: reading a period change value in the current monitoring period of the SAS port;
s202: determining an accumulated change value according to the difference value of the change value of the period and the change value of the previous period;
s203: correcting the accumulated change value according to the magnitude relation between the accumulated change value and the alarm threshold value to obtain a corrected value
S204: judging whether the corrected value is larger than an alarm threshold value; if yes, go to S205;
s205: and taking the SAS port as a failure port.
Specifically, how to correct the accumulated change value according to the magnitude relationship between the accumulated change value and the alarm threshold is not limited herein. Preferably, the accumulated change value is corrected according to the magnitude relationship between the accumulated change value and the alarm threshold, and the correction value may be obtained by the following execution mode:
if the accumulated change value is larger than the alarm threshold value, obtaining a correction value according to a first correction formula;
if the accumulated change value is smaller than the alarm threshold value, a correction value is obtained according to a second correction formula;
the first correction formula is M ═ C + N/2, and the second correction formula is M ═ C + T;
m is a correction value, C is an accumulated change value, N is an alarm threshold value, and T is a difference value between the change value of the period and the change value of the previous period.
It is easily understood that the above provided correction formula is only a better correction formula implemented on the basis of the monitoring method of the SAS port disclosed in the present application, and those skilled in the art can also adopt other correction formulas to reduce accidental errors.
In the following, a monitoring system of an SAS port provided in an embodiment of the present application is introduced, and the monitoring system described below and the monitoring method of the SAS port described above may be referred to correspondingly.
