<ul><li><code>cpu</code>、<code>memory</code>、<code>swap</code>、<code>disk</code></li><li><code>net_in_speed</code> 入站网速、<code>net_out_speed</code> 出站网速、<code>net_all_speed</code> 双向网速、<code>transfer_in</code> 入站流量、<code>transfer_out</code> 出站流量、<code>transfer_all</code> 双向流量</li><li><code>offline</code> 离线监控</li><li><code>load1</code>、<code>load5</code>、<code>load15</code> 负载</li><li><code>process_count</code> 进程数 <em>目前取线程数占用资源太多，暂时不支持</em></li><li><code>tcp_conn_count</code>、<code>udp_conn_count</code> 连接数</li></ul></li><li>duration：持续数秒，数秒内采样记录 30% 以上触发阈值才会报警（防数据插针）</li><li>min 或 max： <ul><li>流量、网速类数值 为字节（1KB=1024B，1MB = 1024*1024B）</li><li>内存、硬盘、CPU 以占用百分比计数</li><li>离线监控无需设置此项</li></ul></li><li>cover： <ul><li><code>0</code> 监控所有，通过 <code>ignore</code> 忽略特定服务器</li><li><code>1</code> 忽略所有，通过 <code>ignore</code> 监控特定服务器<br> 例如：<code>[{"type":"offline","duration":10, "cover":0, "ignore":{"5": true}}]</code></li></ul></li><li>ignore: 选择忽略特定服务器，搭配 <code>cover</code> 使用，内容为服务器 id 和布尔值，例如：<code>{"1": true, "2":false}</code></li></ul><p><strong>完整示例:</strong></p><blockquote><blockquote><p>添加一个离线报警</p></blockquote><ul><li>名称：离线通知</li><li>规则：<code>[{"Type":"offline","Duration":10}]</code></li><li>启用：√</li></ul></blockquote><blockquote><blockquote><p>添加一个监控 CPU 持续 10s 超过 50% <strong>且</strong> 内存持续 20s 占用低于 20%

你有 1、2、3、4 四台服务器和 A、B 两个不同的通知组<br> 1、2 这两台服务器掉线十分钟后给通知组 A 发送通知<br> 3、4 这两台服务器掉线十分钟后给通知组 B 发送通知</p><p>首先你需要先设置好 A、B 两个通知组，然后添加两条报警规则：</p><p><strong>规则一：</strong></p><ul><li>名称：1、2 离线，发送给通知组 A</li><li>规则：<code>[{"type":"offline","duration":600,"cover":1,"ignore":{"1":true,"2":true}}]</code></li><li>通知方式组： A</li><li>启用：√</li></ul><p><strong>规则二：</strong></p><ul><li>名称：3、4 离线，发送给通知组 B</li><li>规则：<code>[{"type":"offline","duration":600,"cover":1,"ignore":{"3":true,"4":true}}]</code></li><li>通知方式组： B</li><li>启用：√</li></ul></blockquote><p><strong>灵活使用参数可以让你的通知功能被充分使用</strong></p><br><h3 id="特殊：任意周期流量报警" tabindex="-1">特殊：任意周期流量报警 <a class="header-anchor" href="#特殊：任意周期流量报警"

周期内双向流量和</li></ul></li><li>cycle_start： 统计周期开始日期（可以是你机器计费周期的开始日期），时间格式为RFC3339，例如北京时间为<code>2022-01-11T08:00:00.00+08:00</code></li><li>cycle_interval：每隔多少个周期单位（例如，周期单位为天，该值为 7，则代表每隔 7 天统计一次）</li><li>cycle_unit 统计周期单位，默认<code>hour</code>,可选(<code>hour</code>, <code>day</code>, <code>week</code>, <code>month</code>, <code>year</code>)</li><li>min/max、cover、ignore 参考基本规则配置</li></ul><blockquote><p>示例:</p><blockquote><p>ID 为 3 和 4 的服务器（ignore 里面定义），以每月 1 号为统计周期，周期内统计的出站月流量达到 1TB 时报警</p></blockquote><p><code>[{"type":"transfer_out_cycle","max":1099511627776,"cycle_start":"2022-01-01T00:00:00+08:00","cycle_interval":1,"cycle_unit":"month","cover":1,"ignore":{"3":true,"4":true}}]</code></p></blockquote><h2
