nodes 命令展示了集群拓扑结构。

前几列告诉您可用的节点并且描述了一下 heap(堆),memory(内存),cpu,和 load(平均负载)。

ip            heap.percent ram.percent cpu load_1m load_5m load_15m
192.168.56.30            9          78  22    1.80    2.05     2.51

最后几列提供了在查看整个集群(特别是大集群)时的一些有用的辅助信息。我有多少个 master-eligiblemaster 资格的)节点。

Columns(列)

下面是一个已存在的 header(标题)的详细列表,它可以传递 nodeattrs?h= 以在有序的列中获取更详细的信息。如果没有指定 header(标题),那么这些标记默认情况下就会有。如果指定了 header(标题),将不使用默认值。

为了更简洁,可以使用别名替换完整的标题名称。列的显示是有序的,它们在下面被列出了,除非指定了其它的顺序(例如,h=attrvalue 与 h=valueattr 相反)。

在指定标题时,默认的输出中标题不会被替换。为了使标题可以出现在输出中,使用 verbose(详细的)模式(v)。标题名将匹配提供的值(例如,pid 与 p 相对)。例如 : 

% curl 192.168.56.10:9200/_cat/nodes?v&h=id,ip,port,v,m
