#### Remote monitoring of Zabbix stats

It is now possible to make some internal metrics of Zabbix server and
proxy accessible remotely by another Zabbix instance or a third party
tool. This can be useful so that supporters/service providers can
monitor their client Zabbix servers/proxies remotely or, in
organizations where Zabbix is not the main monitoring tool, that Zabbix
internal metrics can be monitored by a third party system in an
umbrella-monitoring setup.

Zabbix internal stats are exposed to a configurable set of addresses
listed in the new 'StatsAllowedIP'
[server](/manual/appendix/config/zabbix_server)/[proxy](/manual/appendix/config/zabbix_proxy)
parameter. Requests will be accepted only from these addresses.

To configure querying of internal stats on another Zabbix instance, you
may use two new items:

-   `zabbix[stats,<ip>,<port>]` internal item - for direct remote
    queries of Zabbix server/proxy. <ip> and <port> are used
    to identify the target instance.
-   `zabbix.stats[<ip>,<port>]` agent item - for agent-based remote
    queries of Zabbix server/proxy. <ip> and <port> are used
    to identify the target instance.

To make sure that the target instance allows querying it by the external
instance, list the address of the external instance in the
'StatsAllowedIP' parameter on the target instance.

These items gather statistics in bulk and return a JSON which can be
used as the master item for dependent items that get their data from. A
selected set of internal metrics (i.e. not all) is returned by either of
these two items.

There are also another two new items allowing to specifically remotely
query internal queue stats:

-   `zabbix[stats,<ip>,<port>,queue,<from>,<to>]` internal item - for
    direct internal queue queries to remote Zabbix server/proxy
-   `zabbix.stats[<ip>,<port>,queue,<from>,<to>]` agent item - for
    agent-based internal queue queries to remote Zabbix server/proxy

    stats](/manual/appendix/items/remote_stats)
-   [Internal items](/manual/config/items/itemtypes/internal)
-   [Zabbix agent items](/manual/config/items/itemtypes/zabbix_agent)

##### New templates

New templates are also available for remote Zabbix server or proxy
internal metric monitoring:

-   Template App Remote Zabbix server
-   Template App Remote Zabbix proxy

Note that in order to use a template for remote monitoring of multiple
external instances, a separate host is required for each external
instance monitoring.
