Apache Module mod_heartmonitor

+
+

Available Languages:  en  | + fr 

+
+ + + + +
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
+

Summary

+ +

+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.

+ +
+ To use 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. +

HeartbeatListen Directive

+ + + + + + + +
Description:multicast address to listen for incoming heartbeat requests
Syntax:HeartbeatListen addr: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.

HeartbeatMaxServers Directive

+ + + + + + + + +
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
Compatibility:The value of 0 is accepted only in 2.4.55 and above
+

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.

+

For using flat-file storage (without loading mod_slotmem_shm), + this must be set to 0. The value must be either 0, or bigger or equals 10.

+ +

HeartbeatStorage Directive

+ + + + + + + +
Description:Path to store heartbeat data when using flat-file storage
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 and + HeartbeatMaxServers is set to 0.
