[英]Can we monitor Cassandra schema disagreement using JMX
I know that nodetool describecluster
can give me information about schema disagreements in cassandra . 我知道nodetool describecluster
可以为我提供有关cassandra中架构分歧的信息。 But, i am looking to see if that information is available via JMX .If it is available can some one point me fully-qualified package/metric name for this ? 但是,我正在寻找是否可以通过JMX获得该信息。如果可用,有人可以为此指定我完全限定的包装/度量名称吗?
I am trying setup alert for this using Prometheus . 我正在尝试使用Prometheus为此设置警报。
Yes, you can monitor it with JMX: 是的,您可以使用JMX对其进行监视:
ObjectName: org.apache.cassandra.db:type=StorageProxy
Attribute: SchemaVersions
This will return a key/value pair, with a format similar to: 这将返回键/值对,其格式类似于:
eaceacea-eac7-eac6-eaca-eac75275b=[172.1.xx.xx, 172.1.xx.xx, 172.1.xx.xx]
All the nodes in the same cluster should match the UUID returned. 同一集群中的所有节点应与返回的UUID匹配。
