Data is everything, all kinds of data play a vital role in the production and operation of enterprises, and all business activities rely on indispensable information. Data is like the eyes of business operators, through the data can reflect all the problems, just as the helmsman depends on navigation.

Now the development of every enterprise and organization needs to rely on a large amount of data, and the data has become the most valuable asset of the enterprise. Modern networks are complicated and composed of many components, so it is impossible for us to pay attention to everything. In order to maximize the value of data, we usually use database monitoring tools.

Monitoring a database is no different from monitoring other IT components. The main goal of database monitoring is to ensure that data is available when needed. This sounds simple, but the actual operation is quite complex, in part because of the number and variety of components.

Although a database is an abstract concept, it is made up of very specific things. From hardware to software, database monitoring tools must always ensure that all components are available and run within normal limits.

The most basic element of a database is the hardware on which it runs. Like any computer, these hardware have many adjustable parameters. For example, we need to consider the CPU load, available memory, or processor core temperature. In fact, monitoring a database server is no different from monitoring other servers. The next component to be monitored is the underlying operating system. Some databases run on Windows, while others run on Linux or other Unix distributions. Regardless of the operating system, there are several important parameters to monitor, such as disk space or disk usage. Like hardware, operating system-level database monitoring is no different from other types of monitoring. The last part is the monitoring of the actual database. In essence, the database is just another piece of software running on the server. Therefore, the most basic monitoring is to make sure that the software is running all the time. But most tools mean much more than that. Some check the structure of the database, some measure the response time of the database, and some even execute stored procedures for testing.

Database Monitoring tool-PIGOSS BSM

Through JDBC, PIGOSS BSM monitors mainstream databases, including Oracle, Oracle RAC, DB2, SQL Server, Mysql, Dameng database, etc., and can monitor database key performance indicators, such as table space, lock state, session state, and sort SQL statements that occupy more database resources, making it convenient for administrators to find database bottlenecks.

PIGOSS BSM's monitoring of Oracle draws on the first-line experience of professional Oracle DBA, and precipitates the attention information of Oracle in practical application scenarios to the product, in which the functions such as SQL-TOP sorting and ORA error log are greatly recognized by users, which provides a strong basis for users to troubleshoot database bottlenecks, and finally presents the overall running state of Oracle through an integrated view.

The monitoring system can monitor the following important performance indicators for the database:

Database availability monitoring: it can monitor the key parameters of the database engine, the file storage space designed by the database system, the utilization rate of system resources, the configuration, the current lock resources of the database, the status of the database process, the memory space occupied by the process, etc.

User and system tablespace usage

Usage Monitoring of Database transaction Log Space

Memory usage and status of critical processes in the database

Ability to monitor the status of available lock resources

For Oracle RAC, it can monitor RAC status, cluster status, voting disk information, TNS status, ASM status and so on, and display the global state through an integrated view.
