Apache HTTP Server Version 2.4
Description: | Centralized monitor for mod_heartbeat origin servers |
---|---|
Status: | Experimental |
Module Identifier: | heartmonitor_module |
Source File: | mod_heartmonitor.c |
Compatibility: | Available in Apache 2.3 and later |
mod_heartmonitor
listens for server status messages generated
by mod_heartbeat
enabled origin servers and makes their status
available to mod_lbmethod_heartbeat
. This allows
ProxyPass
to use the "heartbeat"
lbmethod inside of ProxyPass
.
This module uses the services of mod_slotmem_shm
when
available instead of flat-file storage. No configuration is required to
use mod_slotmem_shm
.
mod_heartmonitor
,
mod_status
and mod_watchdog
must be either a static modules or, if a dynamic module, it must
be loaded before mod_heartmonitor
.
Description: | multicast address to listen for incoming heartbeat requests |
---|---|
Syntax: | HeartbeatListenaddr:port |
Default: | disabled |
Context: | server config |
Status: | Experimental |
Module: | mod_heartmonitor |
The HeartbeatListen
directive specifies the
multicast address on which the server will listen for status information from
mod_heartbeat
-enabled servers. This
address will usually correspond to a configured HeartbeatAddress
on an origin server.
HeartbeatListen 239.0.0.1:27999
This module is inactive until this directive is used.
Description: | Specifies the maximum number of servers that will be sending heartbeat requests to this server |
---|---|
Syntax: | HeartbeatMaxServers number-of-servers |
Default: | HeartbeatMaxServers 10 |
Context: | server config |
Status: | Experimental |
Module: | mod_heartmonitor |
The HeartbeatMaxServers
directive specifies the
maximum number of servers that will be sending requests to this monitor
server. It is used to control the size of the shared memory allocated
to store the heartbeat info when mod_slotmem_shm
is in use.
Description: | Path to store heartbeat data |
---|---|
Syntax: | HeartbeatStorage file-path |
Default: | HeartbeatStorage logs/hb.dat |
Context: | server config |
Status: | Experimental |
Module: | mod_heartmonitor |
The HeartbeatStorage
directive specifies the
path to store heartbeat data. This flat-file is used only when
mod_slotmem_shm
is not loaded.
