截至2016年8月28日，我使用Stackdriver监控MongoDB 3.2的问题。
在/var/log/syslog没有提到mongo ，但是如果我在.conf文件中发生configuration错误，它会报错，所以我知道它正在正确加载文件…
所以没有错误，但没有提及mongo在/var/log/syslog和https://app.google.stackdriver.com/services/mongodb声称我没有安装代理。

请注意，实例/节点正确监控，只有MongoDB是有问题的。
/opt/stackdriver/collectd/etc/collect.d/mongo0.conf ：
# scheduled to node: gke-fatih-standard-fb894cbb-d7ue # This is the monitoring configuration for MongoDB. # Look for STATS_USER, STATS_PASS, MONGODB_HOST and MONGODB_PORT to adjust your configuration file. LoadPlugin mongodb <Plugin "mongodb"> # When using non-standard MongoDB configurations, replace the below with #Host "MONGODB_HOST" #Port "MONGODB_PORT" # Must use the load balancer because we don't know the fixed nodePort Host "xxx" Port "27017" # If you restricted access to the database, you can set the username and # password here: User "stats" Password "xxx" </Plugin>
与使用GCE中的StackDriver监视MongoDB 3相关
在做了sudo service stackdriver-agent restart再次sudo service stackdriver-agent restart （我之前完成的），也许约30分钟的原始事件之后，指标现在被Stackdriver检测到。
所以，如果你确定你做的一切正确，没有错误，你可以尝试重新启动stackdriver-agent多次，等待约30分钟。
在/var/log/syslog缺less与mongo相关的任何内容是个问题。 我希望@科里 – 科萨克可以提供更多的信息。
