In other words, client and server can be connect with multiple intermediate nodes respectively, and each intermediate node can be with
Receive and save the status data of client transmission.If server from destination node obtain status data, and destination node by
It is in down state in failure, then server can continue to obtain status number in the intermediate node in available mode
According to.
Specifically, in this case, server in available mode intermediate node continue obtain status data can
To be first to redefine a destination node in the intermediate node in available mode, then continue from the destination node redefined
Obtain status data.Alternatively, since each intermediate node receives and saves the status data of client transmission, it can also
To be successively to obtain status data from multiple intermediate nodes in available mode, for example server can be first from available shape
The intermediate node A1 of state obtains the 5th bar state data received, then continues to obtain from the intermediate node A2 in available mode
The 6th bar state data received are taken, and so on.
It should be understood that the above-mentioned illustrative only carried out to server from the mode that intermediate node obtains status data
Illustrate, in the specific implementation, server can also obtain status data, the disclosure from intermediate node otherwise to the disclosure

According to.Illustratively, target topic can pass through the character or string table of alphabetical form, digital form or both combining form
Show.It should be understood that target topic can be identical for the status data of same client, and for different clients
Status data, target topic can be different.In a kind of possible mode, target topic can be the letter of unique identification client
Breath, for example, referring to Fig. 2, for the status data of customer end A, target topic can by title, label of customer end A etc. into
Row indicates, for example, target topic can be the title " A " of client, then server can obtain mesh from message queue MQ1
The status data that theme is A is marked, so as to get the status data of customer end A.
It should be understood that the failures if server occurs abending etc., and message queue is in available mode, then
Message queue can continue to receive the status data that client is sent.After server restores normal again, it can subscribe to again
The target topic of message queue, so that server can continue the status data for obtaining client from the message queue.Herein
In the case of kind, the available all clients status data to during failure of server, so as to effectively avoid server
The loss problem of client state data during failure.
In a kind of possible situation, server can be also used for analysis state data, when obtaining the generation of status data

1, after status data 2 and status data 3 are parsed, when having obtained the generation of status data 1, status data 2 and status data 3
Between be respectively at 11 points in the morning 15 minutes, at 11 points in the morning 22 minutes, at 11 points in the morning 26 minutes.Wherein, the generation time of status data 3 the latest,
Thus may determine that status data 3 is target state data.
After obtaining target state data, server can be used for working as the generation time of target state data with server
The time of preceding record is compared, and according to comparison as a result, determining the state of client with the presence or absence of abnormal.
In a kind of possible situation, server can work as generation time and the server current record of target state data
Time difference of time when being more than preset duration, it is abnormal to determine that the state of client exists.
Illustratively, preset duration can be obtained according to client status data time interval and determination, such as it is default
Duration can be set as the presupposition multiple that client obtains the time interval of status data, for example client obtains status data
Time interval is 10 seconds, i.e., client is at interval of the status data of acquisition in 10 seconds, then when preset duration can be set as this
Between be spaced 2 times, i.e. preset duration is 20 seconds.In such cases, when the generation time of target state data and server are current
When the time difference of the time of record is more than 20 seconds, server can determine that client does not get newest status data, from
And it is abnormal to determine that client exists, convenient for abnormal existing for discovery client in time.
Further, determining that client deposits in an exceptional case, server can be with outputting alarm prompt information, with logical
It is abnormal to know that the state of the operation maintenance personnel client exists, is repaired convenient for exception of the operation maintenance personnel for client, guarantees net
The normal operation of network system.
Alternatively, depositing in an exceptional case in multiple client, server can be first to the multiple client that there is exception
It is marked, is then sequentially output alarm prompt, to notify the corresponding operation maintenance personnel respective client of multiple client respectively
There is exception in the state at end, disclosure implementation is not construed as limiting this.
In the case where alternatively possible, if the time of the generation time and server current record of target state data
Time difference be less than preset duration, then server can determine the state of client there is no abnormal, then server can be with
The status data that will acquire carries out persistence operation, for example the status data that will acquire directly is saved, or will be obtained
The status data got is assembled according to the time is generated, obtain carrying out after time series data saving, etc., the embodiment of the present disclosure pair
