Using the -proxy option with EMCMD

All EMCMD requests can be routed through a “proxy” DataKeeper service. To do this, append the options

–proxy <proxy_system>–

to the end of the EMCMD command line. The <proxy_system> should be given using the same format as the <system> option. EMCMD will open a connection to the <proxy_system> first, and will request that it forward the EMCMD to <system>. The DataKeeper Service on <proxy_system> opens a connection to <system>, and sends the requested EMCMD to <system>, returning the response to the user.

The -proxy <proxy_system> option allows you to verify that DataKeeper communication between nodes is working.

Example

EMCMD DK_NODE_2 GETSERVICEINFO -proxy DK_NODE_1

Opens a connection to the DataKeeper service running on DK_NODE_1, which in turn opens a connection to DK_NODE_2, forwards the GETSERVICEINFO request, and returns the service information from DK_NODE_2. This can be used to validate that the DataKeeper service on DK_NODE_1 is able to communicate with the DataKeeper service on DK_NODE_2.
