Kirk Lund commented on GEODE-9101:

The javadocs on MemberMXBean are misleading. They state:
{noformat}
/**
* The current number of nodes in this distributed system visible to this
member.
*/
int getVisibleNodes();
{noformat}
However, the value of {{getVisibleNodes()}} is {{nodes}} from
{{DistributionStats}} which reflects the current number of nodes in the
distributed system (including this member):
{noformat}
final String nodesDesc = "The current number of nodes in this distributed
system.";
{noformat}
Users may be depending on {{getVisibleNodes()}} matching the same value as the
{{nodes}} statistic, so the safest change is to introduce a new attribute that
reflects the number of OTHER nodes.
If you really want to change {{getVisibleNodes()}} then you should propose this
on the Geode dev mailing list.

> In documentation states:
> _The current number of nodes in this distributed system visible to this
> member._
> But checking the value of the attribute we have a difference between locator
> and server.
> For example, we have the following system:
> {code:java}
>
> gfsh>list members
> Member Count : 4
> Name | Id
> | -
> locator1 | 192.168.0.145(locator1:26377:locator):41000 [Coordinator]
> locator2 | 192.168.0.145(locator2:26509:locator):41001
> server1 | 192.168.0.145(server1:26648):41002
> server2 | 192.168.0.145(server2:26768):41003
>
> {code}
>
> For locators visibleNodes = 2, but for servers visibleNodes = 3.
> Locators see only servers as visible nodes(In this case it sees *server1* and
> *server2*).
> Servers see first locator and all servers, including itself(In this case
> server1 sees *locator1*, *server1* and *server2*).
