指标告警的设置:
在apache-skywalking-apm-bin/config/alarm-settings.yml文件中
rules:
# 告警规则 名称唯一 必须以_rule 结尾
service_resp_time_rule:
# 度量名称，只支持int long double
metrics-name: service_resp_time
# 操作符
op: ">"
# 阈值 ms
threshold: 1000
# 评估度量的时间长度
period: 10
# 度量有多少次符合告警条件后，才会触发告警
count: 2
# 静默时间 默认情况下，它和周期一样，在同一个周期内只会触发一次。
silence-period: 10
message: 服务【{name}】的平均响应时间在最近10分钟内有2分钟超过1秒
service_sla_rule:
metrics-name: service_sla
op: "<"
threshold: 8000
period: 10
count: 2
silence-period: 10
message: 服务【{name}】的成功率在最近10分钟内有2分钟低于80％
composite-rules:
# 规则名称：在告警信息中显示的唯一名称，必须以_rule结尾
comp_rule:
# 指定如何组成规则，支持&&, ||, ()操作符
