Body limitation.
Step S101: when the call request of remote procedure call is by calculating device node (hereinafter referred to as this node),
Generate the tracking label of this node.
In the present embodiment, it is the basic unit of link tracing that described node, which is a node of distributed system,.Its
In, node can be for using the Tomcat server of Java language；Far call request can be the calling based on http agreement
Request.
In the present embodiment, during link tracing, when call request passes by this node, pass through the tracking mark of this node
Note reflects the case where this node is by far call request call, and reflects this node in call request by this nodes keep track label
Call the relative position in path.As described above, the tracking label is for reflecting whether the request of certain far call is passed through
This node, and reflect that this node calls the relative position in path in call request.Specifically, the tracking of the node marks
It is made of the tracking label of node, the tracking label is the code name of the different nodes in primary calling task, for characterizing simultaneously
Distinguish the different nodes in primary calling task.
Wherein in the present embodiment, the title (or ID) for the node that tracking label is called or passed by by call request is given birth to
At since in the primary specific request of distributed system or task, the title (or ID) for the node for being called or passing by is
Uniquely, the tracking label determined according to nodename (or ID) is also unique in a link tracing, that is, Ke Yiyong
The node that the name of node is referred to as tracking label indicating call request calling or passing by.Tracking label then includes father node less
Label, this node label and task identification (its concrete meaning sees below one section)；Wherein, this node is reference mode, to receive
As this node, the father node refers to without intermediate node and directly issues calling to this node and ask the node of call request
The node asked issues the node of call request.The father node label is the node that call request is issued to this node
Node label.Certainly, described above is one of set-up mode for tracking label, can also there is other setting sides
Formula, such as indicated with Arabic numerals, it is indicated with the Latin alphabet, be will not enumerate herein, as long as in primary calling task
In, different nodes are indicated with different code names.
Following four node (node1, node2, node3 and node4) is specifically described for far call three times, schemes
The 5 call relation schematic diagrames called three times for four nodes.Referring to FIG. 5, assuming that aforementioned four nodes are
Tomcat server, node1 are to be named as TomcatA, and node2 is named as TomcatB, and node3 is named as TomcatC, node4
It is named as TomcatD.
For example, in node A (referred to as TomcatA, i.e. node A are Tomcat server) and node B (TomcatB) two sections
Point realizes far call request, and request data is from TomcatA to TomcatB.After far call request starts, firstly, being directed to one
All requests of secondary calling task mark the secondary calling task, referred to as task identification with TransactionID, for the secondary tune
The call request of the TransactionID is referred to as with the call request between all nodes of task.It is i.e. identical
The node of TransactionID occurs that TransactionID=TomcatA is arranged in a far call task
TIME 1 (is illustrative nature in the value TomcatA TIME 1 of this TransactionID, is obtained in practice according to default
The encoded radio of TransactionID), i.e., TransactionID is marked with the start node comprising calling.Certainly,
TransactionID can also have other set-up modes.
Then, it is called for identical TransactionID or label is tracked in the setting of called node, track the setting side of label
Formula is as previously described；For example, the label of TomcatA and TomcatB is set as SpanID, that is, label is tracked, is distinguished by SpanID
The title of each node；Call request data are from TomcatA to TomcatB, using TomcatB as reference mode (i.e. this node),
Then TomcatA is the father node of TomcatB, indicates father node with pSpanID；Then the TomcatB of this link tracing is made
For this node, tracking label is SpanID=TomcatB, and the father node label of this node is pSpanID=TomcatA, by
Father node label, this node label and TransactionID=TomcatA TIME 1 above-mentioned collectively constitute this node
Tracking label, is indicated with TraceID, and data are also referred to as tracked in the present embodiment.
As described above, call request required for called process or service in addition to comprising holding when a RPC is called and reached
Capable particular content also includes tracking data as described above.In far call, each node includes a tracking mark
TraceID is remembered, with the identical tracking label TransactionID of nodes sharing in a link tracing (Trace)；Link
SpanID and pSpanID is traced back through to arrange to inherit tree construction；TraceID be by TransactionID, SpanID and
The data acquisition system of pSpanID composition, wherein TransactionID indicates calling task ID, and SpanID and pSpanID is indicated
The parent-child relationship that RPC is called.
Being illustrated above a kind of situation is the situation that this node has father node, i.e. this node not instead of root node, intermediate
Node；A kind of implementation of the tracking label for generating this node includes: to receive father node to the far call of this node
Request；The far call request is parsed, obtaining father node is the tracking data that this node generates；It is raw according to the tracking data
The tracking of cost node marks.By taking the TomcatB in Fig. 5 as an example, the tracking label for generating this node includes: reception father node
TomcatA requests the far call of this node TomcatB；The far call request is parsed, acquisition father node is this node
The tracking data of generation, include: in the tracking data task identification TransactionID=TomcatA TIME 1, father's section
Point TomcatA label pSpanID=TomcatA and far call request the task definition to be completed；According to the tracking number
According to the tracking label for generating this node, including generation: task identification TransactionID=TomcatA TIME 1, father node
TomcatA label pSpanID=TomcatA, this node label SpanID=TomcatB.
In addition, if described node is root node, by taking root node TomcatA as an example: the tracking mark for generating this node
Note includes: to call the label that creates a trace according to the call request for being directed to child node for this.Specifically, if this node is root
Node TomcatA creates a trace according to the request of this far call and marks TraceID；Create task identification TransactionID
=TomcatA TIME 1, completing the tracking label of all nodes that this request reaches is TransactionID=
TomcatA\TIME\1；This node label SpanID=TomcatA；TomcatA father node TomcatA ' (not shown) label is
PSpanID=-1 (root indicates that remote request is called and initiates node).
The far call of this node is requested as described above, receiving father node, generates the tracking label of this node, or
After root node generates this nodes keep track label, each node is for after the tracking label for generating the node, is needed in MVC
The tracking data are recorded in (Model View Controller model-view-controller) controller；
Step S102: it according to the tracking of this node label and call request of this node to sub- node, generates child node and chases after
Track data.
As previously mentioned, if this node does not complete this request, being needed again in the primary calling task of distributed system
It sends and requests to next node.Before sending request, this node is according to the tracking of this node label and this node to sub- node
Call request, generate child node track data.
Described marked according to the tracking of this node tracks data with call request of this node to sub- node, generation child node
It include: that tracking label is obtained according to the tracking label of described node；Call request according to described node to sub- node, wound
Build child node label；Child node tracking data are configured by the tracking label of described node and child node label.
Specifically, with continued reference to FIG. 5, after this node TomcatB records the tracking data in MVC controller,
Continue to request to next node TomcatC far call；Acquisition task mark is marked according to the tracking of described node TomcatB
Know TransactionID=TomcatA TIME 1, and can get the father node label pSpanID=TomcatA of this node；Root
Call request according to described node TomcatB to child node TomcatC creates child node label TomcatC；
By the task identification TransactionID=TomcatA TIME 1 and child node mark of described node TomcatB
Label TomcatC is configured to child node TomcatC tracking data；It specifically includes: task identification that child node TomcatC, which tracks data,
TransactionID=TomcatA TIME 1, child node label SpanID=TomcatC, child node father node (i.e. aforementioned
Node TomcatB) label pSpanID=TomcatB.
In practical applications, if complete the request of far call need two with uplink, or simultaneously by two with
On node Tomcat, then for each node, according to the tracking label of this node and this node to the calling of each child node
Request generates child node respectively and tracks data.
For example, as shown in Figure 5, far call is requested after this node TomcatB, at the same by TomcatC and
TomcatD that is, there are two the child nodes of TomcatB, then configures the tracking data of child node C according to foregoing description respectively；Again
It repeats no more.
Step S103: child node tracking data are encapsulated to this node in the far call request of sub- node.
After creating child node tracking data, child node tracking data are encapsulated by predetermined manner to this node antithetical phrase section
In the far call request of point, this request is made to realize link tracing while working on.
Described encapsulate child node tracking data to far call of this node to sub- node by predetermined manner is requested
In include encapsulating the child node according to scheduled format and the position in request data and tracking data.
It is described to encapsulate child node tracking data to this node to one of in the far call request of sub- node
Achievable mode includes: the header file encapsulated child node tracking data to this node to the far call request of sub- node
In.Described encapsulates child node tracking data to this node to one in the header file of the far call request of sub- node
Kind specific implementation can include: the tracking label is written to the header file of far call request of this node to sub- node
In；The head of far call request of this node to sub- node is written using described node label as the father node label of child node
In file；This node is written into in the header file of the far call request of sub- node in the child node label.
Specifically, this node TomcatB is written in the task identification TransactionID=TomcatA TIME 1
To in the header file of the far call request of child node TomcatC；Using described node label SpanID=TomcatB as son
This node is written in the header file of the far call request of sub- node in the father node label pSpanID=TomcatB of node；It will
This node is written in the header file of the far call request of sub- node in the child node label SpanID=TomcatC.For
It the case where multilink or more child nodes, is packaged respectively, concrete mode can be identical with a node mode, no longer superfluous herein
It states.
It is aforementioned by be specifically encapsulated in one of HTTP header optional in each label write-in far call request header file
Configuration it is as follows:
HttpGet.setHeader(PINPOINT_TX_ID,"TomcatA\TIME\1")；
HttpGet.setHeader(PINPOINT_SPAN_ID,"TomcatC")；
HttpGet.setHeader(PINPOINT_PARENT_SPAN_ID,"TomcatB")；
In addition it is also possible in other ways by child node tracking data encapsulation, it is any to be able to achieve encapsulation child node tracking number
According to, and can be included within the protection scope of the application by the mode that next node parses, it is not particularly limited herein.
S104: Xiang Suoshu child node of step sends the call request of encapsulation of data.
After data encapsulate, the encapsulation of data is sent to child node, continues the execution of far call request；This implementation
The request of far call described in example is the call request based on http agreement.
For example, HttpGet get=new HttpGet (" http://TomcatC/hello ")；
HttpResponse response=httpClient.execute (get)；
HttpClient.execute (get) method is according to the information in HttpGet, by child node tracking data envelope
This node is filled to in the far call request of sub- node TomcatC；The calling of encapsulation of data is sent to child node TomcatC
Request.
Step S105: child node receives the call request of encapsulation of data, and generates child node tracking according to call request
Label.
After child node receives the call request of encapsulation of data, son is generated according to call request in the way of step S101
Nodes keep track label, the then number that the data structure of the child node tracking label is marked with this nodes keep track described in step S101
It is consistent according to structure.
The child node receives the call request of encapsulation of data, and generates child node tracking according to call request and mark it
A kind of middle implementation specifically includes: child node receives the call request of encapsulation of data；The call request is parsed, institute is obtained
State child node tracking data；Data, which are tracked, according to the child node obtains child node tracking label.
Specifically, child node TomcatC receives the far call request of encapsulation of data；Far call request is parsed, is obtained
It obtains child node and tracks data, comprising: child node tracking label ChildTraceID and request data, comprising: child node tracking is marked
Task identification TransactionID=TomcatA in note TIME 1, father node TomcatB label is pSpanID=
TomcatB；And far call requests the content to be completed.
The call request is parsed, obtaining the child node tracking data includes:
