Question

有一个OpsCenter监控3个集群，现在无法显示它的密钥空间，因此我无法对其进行操作f.ex.压缩否则监控对于相同的集群似乎很好，所有代理都连接等。

我在opscenterd.log中找到了这个：

2015-08-26 11:03:47+0200 [] ERROR: An error occurred while retrieving all keyspaces.  Traceback (most recent call last):

虽然它自己的群集给了我这个，但在群集日志中没什么可看的：

[cqlsh 4.1.1 | Cassandra 2.0.16 | CQL spec 3.1.1 | Thrift protocol 19.39.0]
Use HELP for help.
cqlsh> describe keyspaces;

KeyspaceMetadata  system  OpsCenter  system_traces

cqlsh> select * from system.schema_keyspaces;

 keyspace_name    | durable_writes | strategy_class                                       | strategy_options
------------------+----------------+------------------------------------------------------+----------------------------
 KeyspaceMetadata |           True | org.apache.cassandra.locator.NetworkTopologyStrategy |             {"SPRAWL":"2"}
        OpsCenter |           True |          org.apache.cassandra.locator.SimpleStrategy | {"replication_factor":"2"}
           system |           True |           org.apache.cassandra.locator.LocalStrategy |                         {}
    system_traces |           True |          org.apache.cassandra.locator.SimpleStrategy | {"replication_factor":"2"}

(4 rows)

想知道从哪里开始，其他2个群集不显示问题，自上次操作后未进行任何更改。尝试按节点重启节点。数据存储代理程序和OPsCenter也没有更改，仍然无法从这个集群中获取密钥空间。

提示赞赏，TIA！

此问题的根源是此处描述的驱动程序中的错误：https://datastax-oss.atlassian.net/browse/PYTHON-192。你有一些复杂的节俭表吗？可能值得将/ usr / share / opscenter / lib / py / cassandra的内容更新为带有修复程序的驱动程序的最新版本或
