   Of course,I just modified the alert rule., here is the SQL insert 
statement.`select * from hzb_alert_define where type = 'periodic'`
   ```sql
   INSERT INTO "public"."hzb_alert_define" ("id", "annotations", "creator", 
"datasource", "enable", "expr", "gmt_create", "gmt_update", "labels", 
"modifier", "name", "period", "template", "times", "type") VALUES (7, NULL, 
'admin', 'promql', 't', 'cpu_usage == 0', '2025-09-18 17:28:43.229194', 
'2025-09-18 17:30:18.085477', '{"severity":"warning"}', 'admin', '测试cpu告警', 60, 
'${instance}(${host})cpu告警', 1, 'periodic');
   ```
