This article mainly introduces the use of Python crawler scripts to crawl down the alarm information of all targets and push them to the WeChat enterprise account application to achieve single-point to multi-target inspection. In this way, the workload of the DBA can be reduced.
If you don’t know about Oracle Enterprise Manager Cloud Control 12c, you can search for information to find out by yourself.
1. Set Incident Manager: All open incidents as the main page opened by the manager, as shown below:
Second, use Python to write crawlers
Use python+selenium+geckodriver to crawl an alarm message and push it to the enterprise account.
Note: You need to install the firefox browser (the Firefox version that comes with Linux by default is lower, please upgrade to the latest version by yourself), and it is written in python2.7. Download the code here:
