agent.alive 监控项 异常报警 #917
Comments
机器A日志: openfalcon server端 nodata日志为: 但明明agent上报agent.alive 值为1 ,为什么该告警项还会触发nodata呢?我们遇到过多次这种情况,agent.alive告警挂掉了,但是进程正常,且其他监控项正常采集上报,且其他告警项正常! |
对比一下 上报的endpoint 和 host表的hostname名称是否一致 我们碰到了 大小写不一致的时候 不填写新的host记录 但是会触发nodata报警 |
agent 版本:Open-Falcon agent version 0.3.x, build fa81b78
问题现象:
机器A上部署agent,负责采集主机监控项,监控项上报日志如下:
机器B上部署transfer和hbs:
且接收信息日志正常。
机器C上部署openfalcon server端,连接均正常。
我在dashboard上设置了机器A agent.alive 监控项的nodata,若中断则上报值为 -1.
但现在机器A 上报信息均为正常,其网卡、cpu、mem等监控信息可在dashboard中查询到,且为实时数据。但是agent.alive则为-1 值,触发告警。重启多次,并且重新部署之后都未恢复。
