Recently when performing performance tests, the developer directly hung all the business tables into the Oracle database because of the space data to be mounted. Several recent tests have found that the response time and throughput are not ideal, after some analysis of the suspect may have problems in Oracle, so I looked for the relevant monitoring program on the net, eventually found spotlight, but no deta

The students who have done Zabbix know that Zabbix collects relevant monitoring data through a dedicated agent or SNMP, and then stores it in the database and displays it in real time. Zabbix monitoring data is mainly divided into the following two categories:Historical data: Historyrelated tables, from the History_uint table can be queried to the maximum, minimu

Continue to the CLI mode test. this time, a simple real-time monitoring and scheduling function of the database is implemented by using the previous "dead loop with latency" method. Function to be implemented: monitor the user table. if a new record is added, add it to table user2. (It can be used in practical scenarios, such as data processing) Below is the PHP code (dbtest. php) The code is as follows:
