可能是你一次发送太多信息被钉钉拒收了。 你可以尝试调整 alertmanager 的 grouping 和 inhibit，尽量不要一次性发送过多报警。避免 alarm fatigue

我也出现了，应该是大量报警下，会把多条报警聚合在一条message，导致too long

我也碰到类似报错，请问楼上几位是怎么处理的？

我是通过alertmanager发给dingtalk的，
重启dingtalk报错依旧， 重启alertmanager报错消失。

还可以尝试修改inhibit_rules配置，消除一些重复报警

inhibit_rules:
  - source_match:      
      severity: 'critical'
    target_match:      
      severity: 'warning'
    equal: ['alertname']
