Oracle监控账号创建【Prometheus】

在Oracle数据库中创建Prometheus监控账号，通常需要创建一个只读账号，该账号可以查询数据库的性能指标。以下是一个创建Prometheus监控账号的示例SQL脚本：

-- 创建Prometheus监控用户
CREATE USER prometheus IDENTIFIED BY <password>;
 
-- 授予Prometheus用户权限
GRANT CONNECT, RESOURCE TO prometheus;
 
-- 授予Prometheus用户查询动态性能视图的权限
GRANT SELECT ON v_$session TO prometheus;
GRANT SELECT ON v_$sesstat TO prometheus;
GRANT SELECT ON v_$statname TO prometheus;
GRANT SELECT ON v_$parameter TO prometheus;
GRANT SELECT ON v_$sysstat TO prometheus;
GRANT SELECT ON v_$latch TO prometheus;
GRANT SELECT ON v_$process TO prometheus;
GRANT SELECT ON v_$lock TO prometheus;
GRANT SELECT ON v_$pgastat TO prometheus;
GRANT SELECT ON v_$system_event TO prometheus;
GRANT SELECT ON v_$timezone_name TO prometheus;
GRANT SELECT ON v_$page TO prometheus;
GRANT SELECT ON v_$datafile TO prometheus;
GRANT SELECT ON v_$tempfile TO prometheus;
GRANT SELECT ON v_$filestat TO prometheus;
GRANT SELECT ON v_$librarycache TO prometheus;
GRANT SELECT ON v_$rowcache TO prometheus;
GRANT SELECT ON v_$memory_dynamic_components TO prometheus;
GRANT SELECT ON v_$memory_size_info TO prometheus;
GRANT SELECT ON v_$memory_target_advice TO prometheus;
GRANT SELECT ON v_$memory_usage_summary TO prometheus;
GRANT SELECT ON v_$memory_availability TO prometheus;
GRANT SELECT ON v_$instance_activity TO prometheus;
GRANT SELECT ON v_$session_event TO prometheus;
GRANT SELECT ON v_$system_event TO prometheus;
GRANT SELECT ON v_$event_name TO prometheus;
 
-- 赋予Prometheus用户查询ADR的权限（如果有ADR）
GRANT SELECT ON sys.dba_audit_session TO prometheus;
GRANT SELECT ON sys.dba_audit_statement TO prometheus;
GRANT SELECT ON sys.dba_audit_object TO prometheus;
GRANT SELECT ON sys.dba_audit_trail TO prometheus;
 
-- 赋予Prometheus用户查询自定义监控视图的权限（如果有）
GRANT SELECT ON custom_monitoring_view TO prometheus;
 
-- 撤销Prometheus用户未使用的权限
ALTER USER prometheus DEFAULT ROLE NONE;
 
-- 设置Prometheus用户的会话参数，例如不限制会话数量
ALTER SYSTEM KILL SESSION 'PROMOTE,ALTER SYSTEM';

请注意，上述脚本中的<password>需要替换为Prometheus账号的实际密码。此外，根据Oracle数据库的版本和配置，可能需要授予更多或更少的权限。在实际操作中，应当只授予Prometheus账号必要的权
