Specific embodiment
Graphic operation
An optimized integration of the invention is graphic operation.Graphic operation is the execution of the operation conditions in reaction profile formula system
The operation performed on figure.
An example of defined execution figure with vertex representation in execution figure as shown in figure 1, be distributed in the present invention
Event in formula system, the association between event is represented with the side on connection summit.Included in execution figure defined in the present invention
Two keys：Causality and polymerization.Then, the present invention proposes two kinds of graphic operations on the basis of figure is performed：Burst
(slicing) and polymerization (aggregation).
To in the diagnosis of distributed system, user can attempt to carry out following operation：1) sought according to causal correlation
Look for relevant information；2) operation information is summarized with the suitable polymerization of the form of classifying or conclusion, is entered with trouble-shooting point
Row is further to be analysed in depth.
In performing figure at one, each run case from mesh distribution mark system is represented as a summit
(vertex).Such as, in Fig. 1, event (i.e. summit) is represented using small rectangle.Such as, on the first machine is run on
One thread 102 includes event b 104, event c 106, and event b 104 therein is made by pintf daily records (printf log)
With event c 106 is defined by asynchronous request.The second thread 110 run on the second machine includes event a 112, thing
Part d 114, wherein event d 114 are defined by asynchronous request.The 3rd thread 120 run on the 3rd machine includes event
E 122, event e 122 is used by request.
Run case in distributed system is to be mutually related.Perform figure in, point to while (while directive) by with
In this association of expression.Different types of side can be used for defining different types of association.As described above, figure is being performed
In, event is by fixed-point representation.For example, connecting a source event (source event) and an endpoints using side (use edge)
(destination event) and with the direction that endpoints are pointed to from source event, source event definition or transfer one
Object, the destination of the object is endpoints and is consumed by the endpoints.The example of the object of this type is network
Message or cross-thread are asked.In Fig. 1, the arrow with direction<C, e>130 and arrow<D, e>132 is the example for using side.
Synchronous side (sync edge) is represented from two synchronizations of the different event of different threads, to ensure to shared right
Unique access of elephant or sequential cross-thread are operated.
Order side (fall-through) is connected to two continuous events in same thread, the direction on order side be from
The event that the event for first carrying out is performed after pointing to.Side in Fig. 1<B, c>140 is exactly order side.
Fragmentation
Burst (slicing) operation of the definition in the present invention not only marks operation using special label (tag)
Information.Fragmentation is utilized and performs figure：A root summit, one root event (root event) of correspondence, the root thing are selected first
Part is probably direct or user related to the phenomenon of failure point of special interest, and root event is selected by user.From selected
Fixed root event (root event) is set out, and finds the event for having cause and effect dependence with the event.The process of searching passes through
Directive Fragmentation realizes that Fragmentation includes preceding to Fragmentation (forward slice) and reverse Fragmentation
(backward slice).Forward direction Fragmentation will find all events for directly or indirectly depending on root event, and reverse
The Fragmentation event directly or indirectly interdependent by the root event is found.It is so-called interdependent, refer to the presence of cause and effect pass between event
System.
In practical implementations, search accurate and complete cause and effect dependence very Expenses Cost and be difficult to.
Therefore, in actual applications, rational approximate it is sufficient that.In a kind of idea, it is considered to all of use while and during order just
It is considered a kind of to the rational approximate of cause and effect dependence.Studies have found that, order side actually can not be hidden
Dependence containing cause and effect.For example, in one kind typical case of message handling system realizes, a thread can continuously receive new arrival
Message and call corresponding Message Processing person.It is also to be connected by order side between the calling of two Message Processing persons, but it is real
On border, between the two Message Processing persons and in the absence of any significant cause and effect dependence.In this case, it is similar
Order side can roll up invalid operation so that the burst of cause and effect dependence becomes inefficient.Therefore, in the present invention,
The concept of cause and effect scope (causal scope) is proposed, cause and effect scope is the concept based on " using side ".Cause and effect scope refers to：
The use side specified for one, all events in the range of cause and effect are all the source event (source that side is used with this
Event), i.e., there is dependence in source summit.More precisely, this uses the endpoints (destination on side
Event), i.e. destination vertex and all events related with the endpoints, i.e., since the endpoints, own afterwards
Event associated therewith, either connects by using while still by order, all will be considered as cause and effect scope it
It is interior and there is causality using the source event on side with this.Such as, in Fig. 1, big rectangle 150,152 and 154 is represented
The example of the cause and effect scope in the present invention.
Forward direction Fragmentation and reverse Fragmentation in the present invention are all based on the realization of cause and effect scope, such as, in Fig. 1
The middle example that the forward direction Fragmentation carried out for root event with event a 112 is represented using dash area.
The interface prototype of Fragmentation is as follows：
Graph<TV, TE>Slicing(
this Vertex<TV, TE>SrcVertex,
Slice.Type type)；

Analyzed using jack interface (socket interface) on system.
One content is related to event, represents the polymerized unit (aggregation unit) belonging to the event.Can define
The polymerized unit of multilayer.Such as, a layer of polymerized unit can be static structure, such as module, class and function.Polymerized unit
Another layer can be operating structure, such as machine, process and thread.Using above-mentioned content and polymerized unit, it becomes possible to right
Event carries out converging operation, and can effectively be reduced after polymerization needs data volume to be processed and information content, improves examining for distributed system
Disconnected efficiency.
The crucial idea of converging operation of the invention is performed on a suitable level of hierarchical structured system
The aggregation of figure, summarizes with to system action.Perform the continuous fragment of the event with identical polymerized unit in figure
Or several events are summarised and gather execution figure (the also execution figure as current level of a level high (segment)
Result figure) in a single event (summit) in.The present invention can be automatic by code position and the mark of run time position
Label are attached in all of event automatically, in this, as a foundation of base polymer operation.Converging operation is one open
Personalized operation, parameter and the degree of polymerization that user can be polymerized with self-defining.That is, the condition of converging operation,
I.e. which event (summit) and side need to be polymerized, and converging operation number of times, that is, carry out converging operation several times, be aggregated to
Which kind of degree all can be by user's sets itself as needed.
