Description

description

Process control The invention relates to a method in which the

Process state of ablau ^¬ fenden in a data processing ^¬ fenden process is monitored and a warning signal is generated when a critical process state is detected. The invention has for its object to provide a method by which can be detected in processes critical process conditions better than with prior art methods.

This object is achieved by a method having the features according to claim 1. advantageous

Embodiments of the method according to the invention are specified in subclaims.

Thereafter, the invention provides that the monitoring of the process process status is done individually.

A significant advantage of the method according to the invention is the fact that can be detected particularly reliable with this critical process conditions; This will be illustrated with an example: In previous procedural ^¬ ren processes are monitored regardless of their presentation process status, so that limits parameters by which it is concluded that a critical process status, must be relatively generous to a any unnecessary triggering Warning signals to avoid. If, for example, the processor utilization caused by the process to be monitored is used as a parameter, then the limit value must take into account each process status, ie the maximum permissible processor utilization during the process. measurement status with the largest processor access; this will usually be the processor load when starting the process. However, the consequence of such a generous dimensioned sens the limit is that an excessive and faulty processor utilization during normal operation of the process can not be revealed as long as does not exceed the Prozes ^¬ sorauslastung the default for the starting operation limit. At this point the invention comes in, by the present invention provided to perform the process monitoring process status individually, by way of playing is at ^¬ for each process status of a process process ^¬ status individually defines when a critical pro- present zesszustand and when not. Particularly preferably, all processes of an overall system are monitored process-individually, and a system-related warning signal is preferably generated if at least one process state of a process of the entire system or the process states of a given group of processes of the entire system are critical.

At a critical state of a process is closed Example ^¬ example, when at least one parameter, to add the respective process state, directly or indirectly loading, a process-status individually predetermined Maxi ^¬ mal- or minimum threshold value is exceeded or fallen below.

It is also considered advantageous if the monitoring of the process takes place not only with regard to critical process states, but also for at least one other

Process state. Therefore, it is considered advantageous if the process state, at least a running in the data processing system ^¬ process is monitored process status individually ^¬ and a state signal is generated which the JE indicates the process status of the process. Such a status signal can indicate, for example, whether the process is in a "healthy state", in an "endangered state", in a "critical state" or in an "unknown state".

The process status-specific monitoring is preferably taken into account in one or more of the following process ^states : starting the process, terminating the process, normal process, pause state of the process.

At a critical process condition is preferred CLOSED ^¬ sen, if a parameter is outside a duel prozessstatusindivi- predetermined parameter range.

For recognizing a critical process state preference ^¬, one or more of the following parameters prozesssta- tusindividuell be considered: CPU load one or meh ^¬ of exemplary processors of the data processing system, memory usage of one or more RAM memory of the data processing system, memory usage of one or more hard drives the data processing system, network utilization and / or availability of one or more networks Datenverar ^¬ beitungsanlage, utilization and / or availability of redundancy danzrechnern the data processing system.

According to a particularly preferred embodiment it is provided that the process can assume one of at least two different ^¬ integrated process status and each process state, at least each being assigned a parameter zesszustand the Pro ^¬ directly or indirectly describes detected for the at least one parameter, a current parameter value and the acquired parameter value with a maximum or minimum threshold value individually specified by process status is compared, and the warning signal is generated when the Pa ^¬ rameterwert exceeds the predetermined process status individually Maxi ^¬ malsch wave value or falls below the duel prozessstatusindivi ^¬ predetermined minimum threshold value.

The process can be, for example, a software application that is operated on a computer or computer system of the data processing system. The process is particularly preferably a control technology application that monitors and / or conducts at least one section of an energy transmission system; monitoring the process states of the control system stands application is preferably carried out in dependence on the status of the process Leittechnikapplika ^¬ tion.

Alternatively, the process can also be an operating system process running on a computer or computer system, the data processing system and, together with other Betriebssys ^¬ temprozessen the operating system of the computer or accounting nersystems the data processing system. In letztge ^¬ named case it is in the process preferably by a control system operating system process, which is run on a computer or computer system, the data processing system and, together with other Leittechnikbetriebssystempro- processes a control operation system of the computer or

Computer system of the data processing system forms, the control system operating system, the operation of at least one control application that monitors and / or directs at least a portion of an energy transmission system allows light.

If the process uses at least one physical resource of the data processing system, it is considered advantageous. see if at least one process status individual parameter indicates the degree of usage of the physical resource.

For example, it is considered advantageous if the process status custom parameter is a maximum reaction time ^¬ and it is checked whether the process responding to a request within the maximum response time.

To most easily read the status of processes always, it is considered advantageous if each process a binary number (binary number) is assigned to describing the jeweili ^¬ gen process status. Preferably, the number of digits of the binary number is at least as large as the number of different process statuses; In this case, it is possible to assign each process status to an individual digit in the binary number and by assigning a

"One" or "zero" to define if a process status is active or not. By assigning a unique position in a binary number, it is also possible a process - for example, temporarily - to assign two or more Pro ^¬ zessstatus, for example, if the process from one process state to another process state transitions. The binary number may be, for example, a 32-bit number. Preferably, the respective process status and the respectively associated process status are displayed in the form of a status signal on a display device for one or more processes. Particularly preferred is an order ^¬ garaging available on the display device which makes it possible with the aid of an input ^¬ device, loading the process status of a process on the user side switch, for example, when displayed on the Ad ^¬ organization used that a process in a critical process state is located. For example, a process can be stopped or restarted if it is in a critical process state and a selbsttäti ^¬ ges coming back in a non-critical process status is probably considered to be un-.

In order to facilitate a switching of the process status of processes which belong to a plurality of processes comprehensive system, is considered to be advantageous if system status individually each process associated with the system is a system status of individual process status is zugeord ^¬ net for the respective ge system and a switching system status is carried out of the system by an automatic switching on of the new system status ^¬ parent process status for the system to process-related se.

The invention also relates to an arrangement for generating a warning signal with a monitoring device that is suitable for monitoring the process state of a process running in a data processing system and for generating a warning signal when a critical process state is detected. According to the invention, it is provided in such an arrangement that the monitoring device is suitable for carrying out process status monitoring on an individual basis for the monitoring of the process.

With regard to the advantages of the arrangement according to the invention, reference is made to the above statements regarding the method according to the invention, since the advantages of the method according to the invention essentially correspond to those of the arrangement according to the invention.

In a particularly preferred embodiment of the arrangement, it is provided that the arrangement is a Leittechnikeinrich- tion for conducting an energy transmission system and the monitoring device is suitable, a Leittechnikappli ^¬ cation, which monitors at least a portion of the Energieübertra ^¬ tion system and / or conducts, and / or to supervise a control technology operating system process.

The invention will be explained in more detail with reference to Ausführungsbeispie ^¬ len; thereby exemplarily show Figure 1 an embodiment of an arrangement for generating a warning signal, whereby also the inventive method will be explained by way of example with reference to the Anord ^¬ ^¬ voltage; Figure 2 shows an embodiment of a display on a

Display device of the arrangement according to Figure 1 and

Figure 3 shows a possible association between different

System Status of a comprehensive system more processes to the process status of the associated Pro ^¬ processes.

For the sake of clarity, the same reference numerals are always used in the figures for identical or comparable components.

FIG. 1 shows an exemplary embodiment of an arrangement 10 for generating a warning signal. The arrangement 1 comprises a monitoring device 20, which communicates with interconnected computers 30, 40 and 50 of a data processing system 60 and monitors the processes on the computers 30, 40 and 50 running processes PI to P6. The monitoring device 20 is connected to a display device 70, on which the monitoring device 20 can display state signals which indicate the respective process state of the processes PI to P6 running on the computers 30, 40 and 50.

FIG. 2 shows by way of example a possible display on the display device 70 according to FIG. It can be seen that the processes PI to P6 are listed in the left-hand column in FIG. For each process, respectively, the process ^¬ status of the respective process and the respective process are given state.

In the figure 2 the process status of processes PI are to P6 designated by the reference numeral Sl to S4, wherein the reference ^¬ sign Sl the process status "Start of the process", the loading ^¬ reference symbols S2 the process status "Normal flow of Prozes ^¬ ses" which Reference numeral S3 denotes the process status "pause status of the process" and the reference symbol S4 denotes the process status "terminate the process".

The reference symbols ZI to Z4 denote the respective process states of the processes PI to P6; it be ^¬ features the numeral ZI a "healthy state", numeral Z2 a "vulnerable state," the numeral Z3 a "critical condition" and the numeral Z4 an "unknown state".

Of Figure 2 can thus be seen, then, that the monitoring device 20 when monitoring the computer 30, 40 and 50 of the data processing system 60 according to FIG 1 to the He ^¬ result has come for the running on the computer 30 process PI process status " Normal process of the process " ^¬ as the process state" healthy state "has. The process P2, which also runs on the computer 30, be ^¬ also found in the process status S2 ("normal process flow"), but this has the process state Z2, so he is in an "endangered state".

The running on the computer 40 of Figure 1 process P3 is like the process PI in the process status "Normalab ^¬ run of the process" and in the process state "healthy state".

The process P4 running in parallel on the computer 40 is currently being started, so that it has the process status S1 ("starting the process"). The process state is normal, so that the process state ZI ("healthy state") is output.

The process P5, which is operated on the computer 50 of the Datenverarbei ^¬ treatment plant 60 in accordance with Figure 1, is in the process status S3, ie in the "Pause" status. For the process P5, the monitoring device 20 could not determine a current process state, so that it outputs the process state Z4 ("unknown state") on the display device 70. For the process P6, parallel to the process P5 on the

Calculator 50 runs according to Figure 1, determines the monitoring ^{¬ device} 20, the process status S4 ("termination of the process") and a "critical process state", which is marked in Figure 2 by the reference numeral Z3.

In summary, be on the display device 70 of Figure 1 so for all of the data processing system 60 from ^¬ running processes PI to P6 not only each Prozesszustän- de but also the associated process statuses in which the respective processes are located.

As can be furthermore seen in Figure 2, is in each case an input field 80 displayed on the display device 70 for each of the processes PI to P6, which allows a Benut ^¬ zerperson the monitoring device 20, by means of a in the figure 1 by the reference numeral 90 characterized input device to the monitoring device 20 and the display device 70 act. It allows the input device 90 to change the respective process status of processes displayed manually by the corresponding desired new pro ^¬ zessstatus is manually entered into the input field 80th The input of the desired new process status can be carried out, for example, by means of a pull-down menu (not shown further in FIG. 2 for reasons of clarity).

As explained in connection with Figure 2, enables it light the monitoring device 20 via the input device 90 so to set the process status of each Prozes ^¬ ses manually. In many cases, however, processes together form an overall system, for example a control system with which a power transmission system can be controlled or routed. Such a control system is identified by the reference symbol SYS in FIG. 3 by way of example. It can be seen that the control system SYS comprises a plurality of individual processes, which are identified in FIG. 3 by the reference symbols PI, P2, P3 and P4.

In addition, it can be seen that the system SYS different system status are assigned, which are marked with the reference ^¬ sign SSI, SS2, SS3, ... SSn. For each system status SSI to SSn, it is determined which pro- Zessstatus the associated processes PI to P4 sol ^¬ len. So the system status SSI is assigned, for example, that all associated processes PI, so should have a status of "start the process" to P4 same process ^¬ status Sl. The system status SSI can thus be referred to as "starting the control system".

The system status SS2 of the control system SYS is associated with other process ^{statuses of} the processes PI to P4, as can be seen in FIG. Thus, the processes are to PI and P2 each have the process status S2 ( "Normal operation of the process"), and the Pro ^¬ processes P3 and P4 indicate the status S3 ( "pause status of the Pro ^¬ zesses"). It is associated with the system status SSn of the control system SYS that all processes PI to P4 should have the process status S4 ("terminate the process"); the system status SS4 thus corresponds to the status "terminate the system". In a corresponding manner, the control system SYS can be given a plurality of system statuses to which corresponding configurations of process status are respectively assigned; this is indicated in the figure 3 by dots. In order to be able to carry out an assignment of the process states individually in a particularly simple manner, the monitoring device 20 can be connected to a database, for example, which is identified by the reference numeral 100 in FIG. In the database 100, for example, it can be stored in tabular form in which parameter values of predetermined parameters process status is to be ^individually closed to a specific process state. Such a table is exemplified below for the process PI and P2, and would look like the rest of the processes except for custom thresholds:

It can be seen in the table above that the individual Prozes ^¬ sen process status personalization parameters and parameter values are assigned, is closed at their exceeding or falling below predefined on process conditions. For example, it can be read in the table that the process PI is assigned the process state Z2 ("endangered state") in the normal ^operating state if the CPU (CPU: Central Processing Unit) of the computer 30 has a predetermined maximum Load between 20% and 40%. In entspre ^¬ chender way all processes are PI to P6 process status individually parameters and parameter limits or parameter predetermined ranges, by means of which the monitoring device 20 can determine which process state exists in the respective process status. To most easily read the status of processes constantly, preferably every process is a binary number to ^¬ ordered that describes the respective process status. Each process status associated with it an individual point in the binä ^¬ ren number at which is defined by assigning a "one" or a "zero" if a process status is active or not. For example, the binary number may be 4-bits long, with the first digit of the binary number being the process status "starting the process", the second location being the process state "normal process ^flow ", the third location being the process state "break state of the process "and the fourth

Job belongs to the process status "terminate the process".

Depending on the allocation of ones and zeros to the respective process state, the binary number (1,0,0,0) can - or alternatively, the inverse binary number (0,1,1,1)) - thus, for example be ^¬ ben that the associated Process is started; the binary number ^¬ (0,1,0,0) - or alternatively (1,0,1,1) - would indicate that the associated process is operating normally, the Bi ^¬ närzahl (0,0,1,0) would indicate that the associated process is in pause status and the binary number (0,0,0,1) would indicate that the associated process is terminating.

By assigning two "ones" (or "zeros"), one could mark the assignment to two process statuses, for example, the binary number (0,0,1,1) can indicate that the process in pause status is about to finish becomes. Reference sign list
