Description
Technical field
The present invention relates to storage area network technical field, relate in particular to a kind of performance index method for supervising of fibre channel media.
Background technology
Along with scientific and technological development, the increase of amount of information, it is more and more huger that External memory equipment becomes, and people are also more and more higher to the requirement of data storage and reading speed.Particularly in recent years, along with the frequent degree of continuous increase and the network application of enterprise network data, the vulgar network that increasing enterprise starts to build oneself meets the needs of growing data storage.
Storage area network (Storage Area Network, SAN) is a kind of simple storage application and network technology new technology of having combined, and its appearance has met the requirement of people to data storage and reading speed.SAN is the special optic fibre channel network that connects memory device and server, is made up of server, optical channel card (network interface card), fibre channel media (or hub) and the optical-fibre channel storage device of supporting optical-fibre channel.Technologically speaking, most important three parts of SAN network are exactly: equipment interface (as small computer system interface, optical-fibre channel, management system connection etc.), connection device (switch, gateway, router etc.) and communication control processor (as IP agreement and SCSI agreement etc.).These three assemblies are added additional memory device and server (comprising a network management server), form a SAN system.
Adopt fibre channel media that storage system is connected with server, high speed data transfer and data sharing, LAN data backup and storage can be provided.Fibre channel media (Fiber Channel switch, FC switch) is the core of SAN, and its runnability is directly connected to the runnability of whole SAN.In order to improve the reliability of SAN, can Adoption Network management server monitor in real time the performance index of fibre channel media, according to the property indices of fibre channel media, thereby send various alarms, thereby realize fault pre-alarming and fault locating analysis to storage area network.
In existing fibre channel media method for supervising, the general performance information that all gathers fibre channel media by the each certain time interval of snmp protocol, is analyzed and is obtained the early warning information of fibre channel media and send alarm by SNMP trap according to flow information.The method can realize the monitoring of the runnability to fibre channel media to a certain extent.But conventionally gather the acquisition strategies underaction of the performance information of fibre channel media, adaptive ability is poor, the alarm signal just remaining unchanged (unadjustable) after setting sample frequency (time interval of collection) and send is single, and in practical application, situation is complicated and changeable.
Summary of the invention
For the deficiency of the method for supervising of existing fibre channel media, the invention provides a kind of performance index method for supervising of fibre channel media, this method for supervising can self adaptation practical situations, adjusts in real time frequency acquisition and metrics-thresholds, completes alarm.
A performance index method for supervising for fibre channel media, comprising:
(1) be divided into several time periods by one day, and set frequency acquisition and the metrics-thresholds of each performance index in each time period;
(2) for any one performance index of described optical fiber switch, data acquisition server gathers the performance index of fibre channel media according to the frequency acquisition of setting, the performance index that collect and corresponding metrics-thresholds are compared, and send corresponding alarm according to comparative result.
Alarm of the present invention can be voice SMS and mail reminder.
In the performance index method for supervising of fibre channel media of the present invention, monitor several performance index of optical fiber switch, and the monitoring of each performance index is independently carried out, first set respectively frequency acquisition and the metrics-thresholds of each performance index according to practical application request, data acquisition server independently gathers each performance index according to the frequency acquisition of each performance index, and compare with corresponding metrics-thresholds, send corresponding alarm according to comparison result.Wherein, data acquisition server gathers the performance information of fibre channel media by snmp protocol.
Described performance index comprise the number of dropped packets of port reads speed, port write speed, transmission, number of dropped packets, transmission rate and the receiving velocity of reception.
Above performance index are to weigh the leading indicator of switch performance, feedback switch service behaviour state.
Described each performance index comprise three metrics-thresholds, are respectively first threshold, Second Threshold and the 3rd threshold value.
For any one performance index:
If these performance index are less than or equal to first threshold, do not carry out alarm;
If these performance index are greater than first threshold and are less than or equal to Second Threshold, send alarm level message notifying;
If these performance index are greater than Second Threshold and are less than or equal to the 3rd threshold value, send alarm level warning prompt;
If these performance index are greater than the 3rd threshold value, send alarm level grave warning.
Set three threshold values for each performance index, according to the magnitude relationship of performance index and threshold value, the rank of alarm is sent in judgement, can effectively avoid answering like this alarm single, thus the problem frequently giving a warning causing.For some performance index (as transmission rate), in certain scope, its value changes and belongs to normal condition within the specific limits, therefore only need observe it and change, do not need to warn, the alarm level therefore directly carrying out is message notifying rank.And according to the scope that exceeds threshold value, be also provided with warning level and grave warning rank, but exceed normality threshold hour, warn, in the time seriously exceeding, serve a grave warning accordingly.By threshold gradient is set, carry out the alarm of different stage, be convenient to supervisor according to different alarm levels, adopt different solutions.
The frequency acquisition of setting with each performance index of difference of time period in one day in described step (1) is also not quite similar.
Under practical situations, different performance index are in the accessed frequency difference of crossing operation of different time periods, and the identical frequency acquisition of unified employing, easily causes the wasting of resources.Therefore according to application demand, in the time of frequent operation, the frequency acquisition of setting is relatively high, operates when relatively less, and the frequency acquisition of setting is relatively low.Accordingly, when data acquisition server gathers the performance information of optical fiber switch in described step (2), first determine the time period under the time point of this collection, the frequency acquisition using frequency acquisition corresponding to described time period as this collection.
Described performance index method for supervising also comprises setting threshold adjustment cycle, adjust the metrics-thresholds of each performance index according to the performance index that gather every a threshold value adjustment cycle, and the metrics-thresholds by the performance index that collect and after adjusting compares and sends corresponding alarm in next threshold value adjustment cycle, wherein, in next threshold value adjustment cycle, for any one time period, adjust in accordance with the following methods the metrics-thresholds of each performance index in this time period:
The first threshold of these performance index in using the minimum value of the performance index that collect in this time period in this threshold value adjustment cycle as next threshold value adjustment cycle,
The Second Threshold of these performance index in using the minimum value of the performance index that collect in this time period in this threshold value adjustment cycle and peaked mean value as next threshold value adjustment cycle,
The 3rd threshold value of these performance index in using the maximum of the performance index that collect in this time period in this threshold value adjustment cycle as next threshold value adjustment cycle.
In practical application, owing to being subject to network environment, the impact of the factors such as the performance of equipment own, the arm's length standard index of performance index also can change or fluctuate, therefore metrics-thresholds is adjusted according to actual conditions by needs, by setting threshold adjustment cycle, add up an index performance in threshold value adjustment cycle, adjust corresponding metrics-thresholds according to the index performance in a upper threshold value adjustment cycle.The threshold value adjustment cycle that normal conditions are set is 3～5 days.
The performance index that collect in this time period in this threshold value adjustment cycle described in the present invention are interpreted as comprising in this threshold value adjustment cycle not all performance index that collect in the same time period on the same day, and this time period was understood to include not in the same time period on the same day.
At the same time section in, if the continuous several times of the performance index that collect are constant, adjusting corresponding frequency acquisition is 1/4～1/2 of former frequency acquisition.
If the performance index that collect change several times continuously, adjust corresponding frequency acquisition and be former frequency acquisition 2～3 times.
In a period of time, the frequency acquisition that the constant or continuous variation of the continuous several times of performance index illustrates setting is unreasonable, need to adjust, after adjustment, at the same time section in, gather this performance index with the frequency acquisition after adjusting, and continue to adjust frequency acquisition according to the situation of change of performance index simultaneously.Conventionally setting is for 3～6 times adjustment cycle, if 3～6 times continuous constant, can think that current frequency acquisition is relatively high, forms network resources waste, therefore reduces frequency acquisition; If performance index change 3～6 times continuously, think that current frequency acquisition is too low, need further to improve frequency acquisition.
The performance index method for supervising that a kind of fibre channel media is provided of the present invention, in this method for supervising, independently each performance index of fibre channel media are monitored, for three metrics-thresholds that are provided with of each performance index, according to the relation of the performance index that collect and metrics-thresholds, send the alarm of different stage.And in the monitor procedure of each performance index, adjust in real time threshold value and the frequency acquisition of each performance index according to the situation of change of performance index, ensure each performance index of effective monitoring and can farthest save Internet resources.
