753653 - add # of active connections to znode output

Status: RESOLVED FIXED

(Cloud Services :: Operations: Miscellaneous, task)

Description

[:Atoll]

Draining sync pools does not immediately close out the connections active to them, as we have a backend timeout of 600 seconds.

Add # of active connections to the znode output for list/drain/undrain so this is more apparent.

The Hash.new |h,k| lines make a lot of undefined errors go away, but I'm not at all certain they're the correct solution.

Still, it does function correctly.

add active connection count to list/drain/undrain output

Patch is buggy and presumed not safe to use, will require reimplementation by someone more versed in the language. The specific call to Zeus to get connection counts is:

+          connections = @ps.connection_count(node)

Bob wrote a tool called "zwait" that does precisely what this would have been used for anyways.

:bobm, could you ship zwait as part of tools::adm and mark this RESOLVED FIXED when that's done?

The zwait tool is part of tools::adm.  Setting this ticket to RESOLVED FIXED.
