CMDB
CMDB here is more biased towards IT equipment management, as this can be done more quickly. Configuration Management on automatic operation and maintenance module.
CMDB here is mainly the entire IT department hardware resources, existing systems, including service suppliers make a management, to provide basic data for future monitoring and automation of operation and maintenance. The platform CMDB building ideas mainly product line and project-oriented.
First, the product line and project
First, determine the company's entire IT product line. Standing on the perspective of the company to be divided. Combined with the company's major departments, and large product groups are divided. After the product line dividing good next step is to sort out all the company's projects. Each item will, in accordance with the product belongs to classify.
Such as: Examples of B2B electronic business, involving the sale of home management systems, order systems, payment systems, logistics systems, reconciliation systems.
Can be roughly divided into:
1. The sale of product line: the sale of home management, order management;
2. Financial Product Line: payment systems, reconciliation system; logistics line: Logistics systems, third-party logistics interface.
Two, IT asset management
After the product line is divided and classified projects. You can clearly see all the company's IT systems. Then comb each project involved a server or a virtual machine.
Then also need to sort from another dimension: the project deployed on each server or virtual machine, services (database, Tomcat, web, etc.) After this step,
Each project involves clear which servers or virtual machines, which projects each server or virtual machine and associated with the deployment of what services and so on.
In those virtual machine host, the host and distributed on which physical machine, and these physical machines has deployed in the cabinet room and the specific number;
Network connection is how and what uplink and downlink, respectively Yes. We have carried out and the number of perfect, from the hardware level to pay attention to this hardware associated with each system. If any hardware and network problems quickly and clearly aware of the system and the impact involved.
Third, supplier management
IT equipment or system basically every company will have to participate in supplier companies. These centralized supplier information management, emergency can contact the vendor at the time of system problems, and help solve carried out.
Production database
Production database data as the basis for an important part, provide the main way for business data monitoring. We have a traffic monitoring module to monitor, rely mainly on the data service database performs data comparison based on business logic, and real-time determination of the accuracy of the business.
Generally, when monitoring and backup of the database will be used as a separate theme (because too important). On the basis of data modules, all production will be centralized database of information collected, it is easy to provide operational target for the operation and maintenance work after the reference database monitoring and backup, to avoid missing.
General production database are classified according to the type of database management (MySQL, Oracle, SQL Server, etc.). Name of the database that is the name of the general business system, simple logo, see the name to know Italian.
Log Data
Log data is one of the important data IT systems can be a good indicator of the health of the system, when the system has problems, they can check the result by pegging logs, troubleshooting.
First, the system log
System log includes the operating system level logs, including physical machine, host, virtual machine deployment and operating system log. Main concern:
1. System operation log of what the user can see what time logged Which operating system do what operation;
2. The security log can determine whether the system has suffered or is under attack, whether there had been dangerous operation;
3. Timing task log you can see whether the timing of the deployment task in the system on time and accurately perform complete.
System Log mainly reflects the operation of the system level, we must do a good job for backup and analysis.
Second, the application log
Excellent service logs general application logs and operational logs.
1. Application Service logs refer to logs generated as Nginx running time, etc., you can see the health of the application services running through it;
2. The operational log is the main part of the business operation of the business system or service error written to the log, a single log file may also be integrated into the application service log.
Business is business operation log auditing, monitoring of vital business data sources.
Third, database log
Data in the database is often the company's core assets. When the database log database reflects each step of the operation of each transaction, as well as monitoring the status of the database is running, a log monitoring and analysis, database logs are indispensable.
Fourth, the device logs
, And the device can directly log response equipment health problems of equipment, can quickly find the cause of the log.
The switch logs, firewall logs. It can be seen through the firewall logs system is under attack of the log can see whether network traffic increased sharply presented sudden steep drop and so on.
Real-time monitoring and log management equipment is an important job log management.
knowledge base
On the basis of the data, we set up a separate repository such a module, containing the main event repository, question bank, a classic case of libraries, library and other solutions.
Event Library are some of the main operation and maintenance events or accidents encountered in the operation and maintenance work, a detailed record of causes and course of events in the event repository. If it comes to changing requirements or the need to modify the system to solve, this time into the incident by the library to library issues.
Library issues related to the problem-solving process, problem-solving process, it may involve changes to the application publishing. A side-feedback system's health problems through statistical library.
A classic case of database records the ways and means to solve the classic problem. Example fault recording firewall, to find the reason how the troubleshooting process to solve the switch fails, a similar solution for troubleshooting reference.
Solutions Gallery to store some of the major classical solutions. As Nginx + uwsgi + Redis deployment scenarios, MySQL's HA, Oracle's RAC solutions and so on. So you can quickly select the solutions in the construction of the new system time.
