[deeply understand tcapulusdb technology] tmonitor module architecture

TcaplusDB The monitoring and alarm of each process module uses Tcaplus Self developed Tmonitor System . This paper aims to guide the operation and maintenance personnel to install and deploy the single machine environment Tmonitor The system is connected to TcaplusDB Configure monitoring alarm .

Tmonitor The module architecture is as follows ：

The picture above shows the new version Tmonitor System architecture diagram . The service is registered and accessed on the page , After successful access, configure relevant process indicators and alarm strategies 、 Aggregation index alarm strategy 、 Alarm shielding strategy . Business machines are deployed in tcm Under the system , By default, by tagent The collection process indicators passed tcp Request sent to Tmonitor Systematic dc_tconnd,dc_tconnd Re pass tbus Transmit data to dcsvr（DataCollectServer）,dcsvr Finally, the data will be stored in DB The corresponding table in . new edition Tmonitor Now supports custom Reporting method , The business process can construct a protocol package and directly send the indicator data to sasvr.Tmonitor The core module is sasvr.Sasvr It contains two subsystems , Statistical aggregation subsystem and alarm decision subsystem , The statistical aggregation subsystem is used to calculate the aggregation index , The alarm decision subsystem generates an alarm according to the alarm strategy configured by the user 、 Aggregation alarm 、 Send alarm . As can be seen from the above description , A set of Tmonitor The system is divided into web Background , The background process must contain at least one dc_tconnd, One dcsvr, One sasvr.dc_tconnd and dcsvr It's one-to-one , One business monopolizes one pair dc_tconnd/dcsvr, One sasvr It can be shared by multiple businesses , It can process the alarm calculation of multiple services at the same time 、 polymerization 、 Send work .

TcaplusDB It's a distributed product of Tencent NoSQL database , The code for storage and scheduling is completely self-developed . With cache + Landing fusion architecture 、PB Levels of storage 、 Millisecond delay 、 Lossless horizontal expansion and complex data structure . At the same time, it has rich ecological environment 、 Easy migration 、 Extremely low operation and maintenance costs and five nine high availability features . Customer coverage game 、 Internet 、 government affairs 、 Finance 、 Manufacturing and the Internet of things .
