Technical field
The present invention relates to the process monitoring technical field of linux system, more particularly in a kind of linux system based on seeing
The fining process monitoring method and system of door dog.
Background technique
In embedded Linux system, since the work of processor usually will receive the interference from external electromagnetic field, make
At run of the program, and endless loop is fallen into, so that the normal operation of program is interrupted, system can not work on, and can make
Dead state is fallen at whole system, or even unpredictable consequence occurs.Therefore, it is examined for the stability to linux system
Consider, it usually needs the process of operations various in linux system is monitored in real time.
In linux system, process monitoring is substantially the IPC (Inter-Process provided using Linux
Communication, interprocess communication) mechanism completes the message transmission between monitoring process and business process.Existing process
Monitoring method generally uses a kind of static monitoring mode, i.e., monitoring process is by reading a existing configuration file (configuration
The business process of all operations in file record linux system), start to supervise all business process in configuration file
Control, during monitoring, monitoring process is by constantly sending signal to each business process, to judge whether each business process is also deposited
, and if it exists, it is abnormal then to illustrate that the business process does not occur program fleet etc.；If it does not exist, then illustrate that the business process may
It is abnormal to there is program fleet etc..
Existing monitor mode is although simple and easy, but following defect is still remained in use process:
(1) the monitoring fineness of existing monitor mode is not high, program fleet etc. whether can only occurs most to each business process
Basic state judged, newest operating status etc. can not more be refined in use state to system and business process
Monitoring, it is difficult to meet process monitoring high quality requirement.
(2) in practical applications, some business process cycles of operation are short, frequency of use is low, past for these business process
Toward without carrying out long-term real time monitoring.And in existing monitor mode, monitoring process can only be unified to the institute in configuration file
There is business process to be monitored, monitor mode is not flexible, the waste for largely monitoring resource is caused, so that whole monitoring efficiency
It is low.
Summary of the invention
The purpose of the invention is to overcome the shortcomings of above-mentioned background technique, provide in a kind of linux system based on guarding the gate

S2: according to the type of monitor mode in monitoring configuration file, judge monitor mode used by this process monitoring
It is that static monitoring or dynamic monitor, is monitored if static state, be then transferred to S3；It is monitored if dynamic, is then transferred to S4；
S3: creation is static to feed dog thread and sends thread；Static state feeds dog thread when system is normal, periodically hard to house dog
Part executes " feeding dog " operation；When sending thread according to the static traffic process name in monitoring configuration file to corresponding business process
When periodically sending specified signal, static state, which feeds dog thread, to judge that corresponding business process is according to the return value of each static traffic process
It is no still to exist, if so, static dog thread of feeding continues to execute " feeding dog " operation, system is made to continue to operate normally；Otherwise, static
Dog thread stopping execution " feeding dog " operation is fed, dwell time is more than system reboot reset after house dog timeout value, end；
S4: creation dynamic feeds dog thread and receiving thread；Dynamic feeds dog thread when system is normal, periodically hard to house dog
Part executes " feeding dog " operation；After having business process to be registered to receiving thread, receiving thread starts to receive by the business process not
The disconnected status frames issued, and pass through the last state of status frames acquisition business process；Dynamic feed dog thread to business process most
The use state of new state and system is monitored, and when business process and normal system, dynamic is fed dog thread and continued to execute
" feeding dog " operation, makes system continue to operate normally；When finding that business process or system occur abnormal, dynamic is fed dog thread and is then stopped
" feeding dog " operation is only executed, more than after house dog timeout value, system reboot resets dwell time, terminates；
S4 specifically includes the following steps:
S401:, which creating, and initializes dynamic feeds dog thread, will creation communication channel and process status information when initialization
Table, wherein process status information table is used to store the status information of all monitored business process, is transferred to S402:

With reference to the accompanying drawing and specific embodiment the present invention is described in further detail.
Shown in Figure 1, the embodiment of the present invention provides the fining process monitoring based on house dog in a kind of linux system
Method, comprising the following steps:
S1: creation monitoring configuration file, monitoring configuration file include system free memory lower bound threshold value, house dog time-out
Value, the type of monitor mode (dynamic monitoring or static monitoring) and static traffic process name, are transferred to S2.
When specific operation, the format that configuration file is monitored described in S1 is " configuration item=entry value ", wherein in the system free time
Leave boundary's threshold value is indicated with configuration item min-memory；House dog timeout value is indicated with configuration item watchdog-timeout；Prison
The type of prosecutor formula is indicated with configuration item type；Static traffic process name is indicated with configuration item task.
S2: according to the type of monitor mode in monitoring configuration file, judge monitor mode used by this process monitoring
It is that static monitoring or dynamic monitor, is monitored if static state, be then transferred to S3；It is monitored if dynamic, is then transferred to S4.
S3: creation is static to feed dog thread and sends thread；Static state feeds dog thread when system is normal, periodically hard to house dog
Part executes " feeding dog " operation；When sending thread according to the static traffic process name in monitoring configuration file to corresponding business process
When periodically sending specified signal, static state, which feeds dog thread, to judge that corresponding business process is according to the return value of each static traffic process
It is no still to exist, if so, static dog thread of feeding continues to execute " feeding dog " operation, system is made to continue to operate normally；Otherwise, static
Dog thread stopping execution " feeding dog " operation is fed, dwell time is more than system reboot reset after house dog timeout value, end.
When specific operation, it is the spacing wave (being defined by POSIX.1 standard) that number is 0 that signal is specified described in S3.
S4: creation dynamic feeds dog thread and receiving thread；Dynamic feeds dog thread when system is normal, periodically hard to house dog
Part executes " feeding dog " operation；After having business process to be registered to receiving thread, receiving thread starts to receive by the business process not
The disconnected status frames issued, and pass through the last state of status frames acquisition business process；Dynamic feed dog thread to business process most
The use state of new state and system is monitored, and when business process and normal system, dynamic is fed dog thread and continued to execute
" feeding dog " operation, makes system continue to operate normally；When finding that business process or system occur abnormal, dynamic is fed dog thread and is then stopped
" feeding dog " operation is only executed, more than after house dog timeout value, system reboot resets dwell time, terminates.
House dog hardware is commonly called as " house dog " (watchdog), and house dog can be built in processor, also can handle device
External, the present embodiment uses external house dog.
House dog allows system to realize continuous work under unmanned state, its working principle is that: watchdog chip and place
An I/O pin for managing device is connected, it is special periodically toward feeding on this pin of house dog by process control for the I/O pin
Determine signal (pulse or low and high level), this program be dispersedly be located at other control programs in, once processor due to interference
It causes to fall into a certain program segment after program fleet when entering endless loop state, writes the program (being commonly called as " feeding dog ") of house dog pin
Just it cannot be performed.This when, the signal that watchdog chip is sent due to cannot get processor, just in it and processor reset
A reset signal is sent out on the connected pin of pin, resets processor, i.e. start bit of the program from program storage
It sets and starts to execute, just realize the automatic recovery of processor in this way.
The core of house dog is one, and from the counter subtracted, counter starts to subtract certainly after house dog setting initial value, if
It has been more than that house dog timeout value does not go also to feed dog, then house dog counter will reduce to 0 so as to cause house dog interruption, has caused
System reset.
It is shown in Figure 2 when practical operation, S4 specifically includes the following steps:
S401:, which creating, and initializes dynamic feeds dog thread, will creation communication channel and process status information when initialization
Table, wherein process status information table is used to store the status information of all monitored business process, is transferred to S402:
Communication channel of the invention use message queue or pipeline, i.e., the transmission of status frames by message queue or pipeline come
It realizes.Using the chained list that can be regarded as a message when message queue, it regards message as a record, and this is remembered
Record has specific format and specific priority.There is the process of write permission that can add according to certain rules message queue
Add new information；There is the process of read right that can then read message from message queue message queue.The sender of this message
The advantages of formula is: the message that sender need not wait recipient to check that it is received can work on down, and recipient
If do not receive message also without waiting for.
S402: dynamic feeds dog thread creation and starts receiving thread；After receiving thread starting, dynamic is fed dog thread and is entered
" feeding dog " circulation: when system is normal, " feeding dog " operation periodically is executed to house dog hardware；When there is business process to be registered to reception
After thread, the status information for the business process currently registered can be added in process status information table by receiving thread, business into
Journey constantly sends status frames to receiving thread by communication channel, and receiving thread obtains business process according to the status frames received
Newest status information, and update process status information table；Dynamic feeds dog thread and inspects periodically process status information table, and in real time
The use state information of acquisition system, when business process and normal system, dynamic feeds dog thread and continues to execute " feeding dog " behaviour
Make, system is made to continue to operate normally；When finding that business process or system occur abnormal, dynamic feeds dog thread and then stops executing
" feeding dog " operation, dwell time are more than system reboot reset after house dog timeout value, end.
Wherein, process status information table can use chained list or storage of array；Table 1 is process status information table list item, table 2
For state frame structure:
Table 1, process status information table list item
| Process number | Thread number | Terminate the time | Exception code | Prompt information |
| 4Bytes | 4Bytes | 4Bytes | 4Bytes | (1-16)Bytes |
Table 2, state frame structure
| Process number | Thread number | Terminate the time | Exception code | Prompt information |
| 4Bytes | 4Bytes | 4Bytes | 4Bytes | (1-16)Bytes |
Include following field by table 1, table 2 it is found that the list item of process status information table and the structure of status frames are identical:
Process number: for identifying the business process for sending status frames；
Thread number: for sending the thread number (or handle) of status frames in identification service process；Pass through the information field
What can be will be apparent that knows, which the specific thread for sending status frames is, that is to say, that once the appearance of some business process is different
Often, we can smoothly find specific corresponding thread number by the field, to realize the thread-level to business process
Monitoring is more advantageous to abnormal positioning and investigation so that monitoring is more fine, accurate；
It terminates the time: indicating that business process sends the largest interval value of status frames, value >=0 next time；
Abnormal coding: the anomalous sign current for identification service process, it is consistent with the errno coding of system；
Prompt information: the information to go wrong for alerting certain thread.
Wherein, process number, thread number, termination time, abnormal coding use big end syllable sequence (network bytes sequence).Prompt
(the corresponding UTF-8 of ascii character-set is compatible, therefore is concentrated use in the character that appendix A PI is limited using ASCII character for information
UTF-8 and ASCII are ok), big small end problem is not present, sequentially sends.
More specifically, in S402, it, will be to process status information table when receiving thread updates process status information table every time
Time field is terminated to be reset；When dynamic hello dog thread inspects periodically process status information table every time, process status will be believed
The termination time field of breath table carries out subtracting one (update) operation；Once the termination time field of a certain business process is kept to 0, then table
There is exception and (exceeds schedule time and do not receive status frames, then it is assumed that business process " is died " or run in the bright business process
Fly).
In addition to this, in S402, when dynamic hello dog thread inspects periodically process status information table, will be believed according to process status
The abnormal code field for ceasing table, judges whether the exception will affect the operation of system, if so, it is different to show that business process occurs
Often；Otherwise, show that business thread does not occur exception.
Further, the use state information of real-time acquisition system described in S402, specifically includes the following steps: passing through df
Order obtains current Flash utilization rate；Current system memory usage is obtained using cat/proc/memeinfo order；It uses
Cat/proc/stat order obtains current system CPU usage.There is exception in system described in S402, specifically includes following feelings
Condition: current Flash utilization rate is beyond 80% or current system memory usage beyond system free memory in monitoring configuration file
Lower bound threshold value or current system CPU usage exceed 80%.
In order to improve the validity and reliability of entire monitoring process, business process described in S402 passes through communication channel not
Break to receiving thread send status frames when, business process judges the transmission state to status frames, if transmission process goes out
Mistake, business process will solve registration from receiving process.
In practical operation, receiving thread and dynamic feed dog thread when accessing process status information table, it may occur however that thread
Competition.In order to avoid race problem, receiving thread and dynamic feed dog thread and need to make when being written and read process status information table
Use mutual exclusion lock.Specifically, shown in Figure 2, in S402, receiving thread when updating process status information table, will lock up into
Journey status information table；In S402, when dynamic hello dog thread inspects periodically process status information table, process status information will lock up
Table.
