监控集群cache状态

时间：2025-03-22 09:07:30

     jgroup包中附带的一个监控集群中各服务器的信息交换状态、配置信息等的命令。

     命令参数如下：
$ java -help
Probe [-help] [-addr <addr>] [-bind_addr <addr>] [-port <port>] [-ttl <ttl>] [-t
imeout <timeout>] -query <query>

 

 

参数解析:

  • -addr: 根据多播地址查询集群服务器信息，即根据多播地址查询本多播地址下的集群服务器cache状态

  • -bind_addr: 根据服务器信息ip地址查询服务器cache状态

  • -port:多播端口查询

  • -ttl: the time-to-live (in hops): the greater the more hosts will you reach

  • -timeout: how long to wait (in seconds)

  • -query: a string that defines a subsystem to be listed, . "jmx" or "props". Example: -query "jmx" -query "props"

几个常用命令参数及例子

1.查询所有集群节点（）

[portal@oa-tydb1 cas_prod_domain]$ java -cp jboss-lib/  -timeout 500 -addr 229.1.194.41

-- send probe on /224.0.75.75:7500


#1 (266 bytes):
member=10.212.194.29:1348 (CAS-Cache-Cluster)
local_addr=10.212.194.29:1348
cluster=CAS-Cache-Cluster
view =[10.212.194.27:33253|1] [10.212.194.27:33253, 10.212.194.29:1348]
version=2.6., cvs="$Id: ,v 1.59.2.10 2008/10/10 10:13:34 belaban Exp $"

注：为集群中能够相互联系的各服务器ip及联系端口，如果与全部服务器已经列出说明服务器之间已经建立了连接，

          以上显示说明此集群服务器中的两台服务器已经建立连接

      2 .CAS-Cache-Cluster为集群配置中的ClusterName属性，如果次属性与配置文件中一直，说明此服务器监控的是

        该集群的服务器
