晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之,复前行,欲穷其林。 林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田、美池、桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。 见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,咸来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”(间隔 一作:隔绝) 既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。 南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。

E.g. `"SELinux is preventing /usr/bin/bash from ioctl access on the unix_stream_socket unix_stream_socket."` * `report_count(i)`: count of reports of this alert * `audit_event(as)`: an array of audit events (AVC, SYSCALL) connected to the alert * `plugin_analysis(a(ssssbb)`: an array of plugin analysis structure * `if_text(s)`: * `then_text(s)` * `do_text(s)` * `analysis_id(s)`: plugin id.

Typically the value is between 1 - 100. Higher value means that the analysis should have higher priority then other with lower values. * `first_seen_date(t)`: when the alert was seen for the first time, number of microseconds since the Epoch * `last_seen_date(t)`: when the alert was seen for the last time, number of microseconds since the Epoch * `level(s)`: "green", "yellow" or "red" *** ##### get_all_alerts() -> a(ssi) Returns an array of *local_id*'s, *summary*'s, and *report_count*'s of all current alerts in a setroubleshoot database ###### return values * array of * `local_id(s)`: an alert id in a setroubleshoot database * `summary(s)`: a brief description of an alert.
