Detailed Description
The invention is further described below with reference to the accompanying drawings.
Referring to fig. 1, a method for performing an early warning notification by a short message reply control time wheel algorithm of the present invention includes the following steps:
step S1, short message early warning template information is configured in a database;
step S2, receiving a starting early warning request, reading short message early warning template information of a database, combining the receiving parameters of the early warning request to organize a unit task data structure and storing the unit task data structure in a corresponding slot position of a time wheel array;
step S3, each time wheel array with the subscript corresponds to a slot position, unit task data are arranged in the slot position, the subscript of the time wheel array is moved one bit per second, whether the data in the slot position corresponding to the time wheel array of the current subscript has a task or not is judged, if yes, a coroutine is started to traverse the task on the current slot position of the current time wheel data, and if not, the movement is continued;
step S4, judging whether the time round of the task is equal to the current round of the system, if yes, executing the task content in the current round, and if not, waiting for the next time;
step S5, receiving the short message reply, and judging the content of the short message reply so as to intervene the tasks on the time round group;
and step S6, receiving the early warning removing request, receiving the identifier of the short message early warning template information on the parameter, and removing the task of the template identifier on the time wheel array, thereby realizing the purpose of solving the problem of accurate notification of the early warning system.
The invention is further illustrated by the following specific examples:
step one, configuring short message early warning template information by a database, and configuring template identification, template content parameter number and notification mobile phone number.
The present short message notification system is used in a mall system for illustration. Firstly, a piece of short message early warning template data is established in a short message early warning template table of a database. Suppose the template is identified as "shop _ war", the template content is "the mall system starts at { time } and has an error { error }, please process in time", the number of the template content parameters is 2, and the mobile phone number is notified 18912345678. Execute sql statement insert _ war _ tb (code, content, args _ count, mobile) values ("shop _ war", "mall system starts at time, error occurs { error }, please handle in time", 2, "18912345678").
And step two, receiving a start early warning request, wherein the receiving parameters comprise template identification, template content parameters and notification intervals, reading short message early warning template information of a database, and organizing unit task data structures by combining the receiving parameters to store corresponding slot positions of the time wheel array.
The short message notification system is used as a general system and provides an interface for triggering the start of early warning for an access party. The receiving parameter is as follows, template identification ═ shop _ ward ", template content parameter { ' time ' {: 2022-04-0519: 30:58 ', ' error ═ commodity database link failure ' }", and notification interval is 300. Reading short message early warning template data of 'shop _ war', executing a sql statement select from code to obtain template data, and replacing corresponding parameters on corresponding template content to obtain final short message content, wherein the short message content is 'Shangcheng system starts from 2022-04-0519: 30:58, and the commodity database is failed to be linked and needs to be processed in time'; the notification interval 300 indicates notification once for 300 seconds, that is, 5 minutes; the formula of the index of which slot is placed is (sys _ timerray _ index + interval)% 3600, since if it exceeds 3600, a modulus is taken to obtain the corresponding index; the formula of round of the task is sys _ round + ((notification interval + sys _ timerray _ index)/3600), which results in round being 0, sys _ round is the current round of the system, sys _ timerray _ index is the current subscript of the system time round, and sys _ round and sys _ timerray _ index are explained in the step three-time round correlation algorithm. Organizing the above information into a task structure { "code": shop _ war "," content ": the mall system starts from 2022-04-0519: 30:58, a failure of wrong commodity database link occurs, and the mall system is required to process timely", "mobile": 18912345678 "," interval ": 300", "round": 0 }
And step three, moving the time wheel subscript one bit per second, if the subscript of the data has a task, starting a corotation to traverse the task at the current slot position, judging whether the time round of the task is equal to the current round sys _ round of the system, and if so, executing the task content. If the last bit of the time wheel array is traversed, the system current time round sys _ round is added with 1, and the subscript sys _ timerray _ index continues to move from 0.
The system sets a time wheel array sys _ timearray with length of 3600, and this array has 3600 slots, which represents 3600 seconds, namely 1 hour. The current subscript sys _ timerray _ index of the time wheel indicates which slot the system is currently executing a task on, the sys _ timerray _ index is incremented by 1 every second, and the position where the sys _ timerray _ index goes indicates that the task list on the corresponding slot is to be executed. And a task list is placed on each slot, which indicates that the system traverses to the slot, and the task list on the slot is executed. When the index sys _ timerray _ index traverses to the last bit of the array, the sys _ timerray _ index is reset to 0, and the current time round sys _ round is added with 1, the role of the current time round sys _ round is to satisfy such a task for more than 1 hour, because the array of 3600 can only represent the time schedule within the 1 hour, and the comparison between sys _ round and round in the task structure can know whether the task is to be executed at the current time.
The system judges whether task data exist on the time wheel array sys _ time _ index +1 every second, if the length of the task list is larger than 1, a task list on the slot is started to be asynchronously traversed, whether round on the task is equal to the current time wheel sys _ round, if yes, execution is performed in the following round, if yes, short message notification is performed according to data in the task structure task, and round does not exist and is not smaller than the sys _ round.
And after the task is executed, removing the task from the task list of the current slot position, and adding the task again for inter slot positions according to the time interval on the task data task, which indicates that the task is executed again after the inter second, wherein if the range of the time round group 3600 is exceeded after the current subscript is added with the inter, the round and the slot position index on the task need to be recalculated according to the formula in the second step.
Step four, receiving the short message reply, judging the content of the short message reply, stopping all the early warnings at this time by stop, and removing all the tasks in the time wheel array; delay n indicates that the notification continues after the delay of n seconds, and the original task on the time round number group is shifted back by n bits; next n denotes the turn of the original task on the time round array plus n, skipping n cycles.
After receiving the early warning short message sent by the short message notification system, the system responsible person can reply the short message according to the actual situation so as to intervene the tasks on the time round group.
If the person in charge of the early warning information system evaluates that the early warning needs to be solved in 30 minutes, if the early warning does not need to be notified repeatedly in 30 minutes, the short message delay 1800 is replied, and the notification is performed after the early warning is delayed for 30 minutes at the interval of the original tasks. After receiving the reply, the system traverses the task of finding the code shop _ war on the time wheel array sys _ timearray, the added subscript is 1800, and round and index need to be recalculated according to the formula in the step two.
If the person in charge of the warning information system wants to skip for 4 times of intervals, namely 20 minutes, replying a short message next5, which means that 4 times of intervals are skipped over the intervals of the original task, namely, the notification is performed at the 5 th interval, after receiving the reply, the system traverses the task of finding the code _ shop _ war on the time wheel array sys _ time _ arrival to obtain the notification interval of 300, the added index is 300 (4+1) of 1500, and round and index need to be recalculated according to the formula of the second step.
If the task of the person in charge of the early warning information system is not an important error, the system can automatically reply to normal, and if the person does not want to receive the early warning information repeatedly, stop can be replied to indicate that the follow-up notice of the early warning is hoped to stop. After receiving the reply, the system traverses the task of finding the code shop _ war on the time wheel array sys _ timearray, and removes the task.
And step five, receiving the early warning removing request, receiving the template identifier of the parameter, and removing the task of the template identifier on the time wheel array.
Besides receiving the short message reply to intervene the task of the time wheel, the system also needs to provide an interface for relieving the early warning, and when the system problem is repaired, the early warning needs to be relieved. The interface receiving parameter has a template identifier code ═ shop _ war ", a task of finding the code ═ shop _ war on the traversal time wheel array sys _ timerray is traversed, and the task is removed.
The invention is used as a general short message notification service, does not relate to specific system monitoring, and is monitored by each system to request the short message notification system to trigger subsequent short message notification. 1. The database is configured with short message early warning template information, and template identification, template content parameter number and notification mobile phone number are required to be configured. 2. Receiving a start early warning request, wherein the receiving parameters comprise template identification, template content parameters and notification intervals, reading short message early warning template information of a database, and organizing a unit task data structure by combining the receiving parameters to store corresponding slot positions of a time wheel array. 3. And moving the time wheel subscript by one grid every second, starting a corotation to traverse the task at the current slot position if the slot position has the task, judging whether the time wheel of the task is equal to the current wheel, and executing the task content if the time wheel of the task is equal to the current wheel. If the last bit of the time wheel array is traversed, then the current time round is incremented by 1 and the subscript continues to move from 0. 4. Receiving a short message reply, judging the content of the short message reply, stopping all the early warnings at this time by stop, and removing all the tasks in the time wheel array; delay n indicates that the notification is continued after the delay of n seconds, and the original task on the time wheel array is shifted backwards by n bits; next n denotes skipping n rounds, the round of the original task on the time round array plus n. 5.
