Application of time series database in monitoring operation and maintenance platform

The epidemic in Beijing suddenly struck , We all work at home , But the epidemic can't stop the pace of open source projects , Before you know it “ Outside Jesse On _Infra” The column has gone through 2 More than a month , Here comes the eleventh issue . In this issue, we will continue to talk about TSDB Application in monitoring operation and maintenance platform . 

This article only represents personal views , If there is bias , Please ask Hai Han. ～

Now we live in an information-based world , More and more data are automatically collected by various monitoring equipment . such as , Surveillance cameras 、 web camera 、 Environmental monitoring equipment 、 Meteorological data acquisition equipment 、 Hydrological data acquisition equipment, etc . These monitoring devices upload the data in real time through the network after data collection , It brings great convenience to our life , At the same time, it also saves a lot of human and material resources .

The number of monitors has soared , Meet challenges in operation and maintenance

However, with the rapid rise of the number of monitoring equipment , In terms of operation and maintenance, we have also encountered new pressures and challenges . The main performance is ：

（1） The cost of maintenance and replacement of monitoring equipment is high , Many devices are used in harsh environments , Easily damaged .

（2） High maintenance time and cost . The distribution of monitoring equipment is very scattered , Many installation locations are remote , This leads to an increase in the intensity of maintenance work , The cost is huge .

（3） It is difficult to judge the fault , Unable to accurately maintain . Especially when the monitoring equipment is offline , It is difficult for us to judge whether the fault is caused by power supply fault or network fault . This leads to a large number of faults that could be solved only by power failure and restart , But we spent a greater price to solve it on the spot . In view of the above three problems , How to quickly determine the cause of failure , Perform remote troubleshooting , It has become an urgent problem to be solved by the operation and maintenance monitoring platform .

Deficiencies of current operation and maintenance platform

According to our observations , At present, the existing operation and maintenance management platform has great problems and deficiencies , There are three main points ：

（1） The monitoring operation and maintenance platform can manage a limited number of monitoring devices at the same time , Its performance needs to be improved urgently .

（2） The security and reliability of the monitoring operation and maintenance platform are insufficient , The product has no redundant design .

（3） The compatibility between the monitoring operation and maintenance platform and the front-end data acquisition equipment is insufficient , Some other types and monitoring equipment from other manufacturers , Can't communicate with it , You can't upgrade existing equipment . therefore , Facing so many problems , The general monitoring operation and maintenance platform based on time series database has become our necessary choice .

Monitoring operation and maintenance platform based on time series database

Briefly speaking , We can monitor the operation and maintenance platform , It is divided into three parts . They are ： Status acquisition equipment 、 Operation and maintenance management platform and operation and maintenance visualization system .

Status acquisition equipment , It is mainly responsible for collecting the operation status and information of various monitoring equipment , such as , Power Supply 、 The Internet 、 Sensors, etc . It is usually installed in the monitoring box of the front-end equipment , And has universality 、 Extensibility 、 High reliability and easy maintenance . When the status acquisition device collects data , It will send the data information to the operation and maintenance management platform .

Operation and maintenance management platform Mainly responsible for receiving 、 Storage 、 Manage operational data from status acquisition devices . It is also in this link , Time series database will show its powerful role . Because the status data of monitoring equipment has obvious characteristics of time series data , So in using traditional relational database , In storage space 、 Write and query speed and reliability cannot meet the requirements . therefore , We can use time series database to store a large number of monitoring equipment data with time series characteristics , Other business data with non temporal characteristics continue to be stored in the traditional relational database .

Last , We build a set of these stored data Visual operation and maintenance platform system , Through the visual rendering of monitoring operation and maintenance data , We can provide necessary support for the intelligent operation and maintenance of enterprises .

in summary , The monitoring operation and maintenance platform based on time series database solves the problems of difficult equipment fault location and high operation and maintenance cost of traditional operation and maintenance platform . It provides a more intelligent 、 Cheap 、 Efficient solutions , And can support the operation and maintenance management of a large number of monitoring equipment . It has shown great economic benefits and market potential .
