<resource-agent name="kamailio">
<version>1.0</version>
<longdesc lang="en">
Resource agent for the Kamailio SIP proxy/registrar.
Multiple instances are possible when using following parameter combinations:
Parameters for Kamailio instance 1:
listen_address=192.168.159.128
monitoring_ip=192.168.159.128
proto=udptcp
port=5060
Parameters for Kamailio instance 2:
listen_address=192.168.159.128
monitoring_ip=192.168.159.128
proto=udp
port=5070
conffile=/etc/kamailio/kamailio2.cfg
kamctlrc=""
Only one instance can be monitored via the command "kamctl monitor"
because the kamctl tool of kamailio 4.x is not designed for multiple
instances. Therefore, the provided kamctrlrc file path needs to be
empty for instance 2, 3 ...
Parameters for a third Kamailio instance:
listen_address=192.168.159.128
monitoring_ip=192.168.159.128
proto=tcp
port=5080
conffile=/etc/kamailio/kamailio3.cfg

Note: The following "kamailio.cfg" code sniplet is part of an XML section.
Therefore it contains two &amp; characters, which need to be replaced
with two ampersand characters within "kamailio.cfg":

<parameter name="kamctlrc" unique="0" required="0">
<longdesc lang="en">
The location of the "kamctlrc" file for the Kamailio instance.
The file "kamctlrc" is the Kamailio configuration file for its "kamctl" control tool.
This parameter only needs to be provided in case of using multiple Kamailio server
instances on a single cluster node:
In case that the parameter "kamctlrc" is not empty, this ressource agent monitors
the health state of the Kamailio server via the command "kamctl monitor 1". This
setting is recommended in case of using a single Kamailio server instance.
In case that the parameter "kamctlrc" is empty, the ressource agent does not
monitor the health state of the Kamailio server instance via the "kamctl" command.
Please note that the "kamctl" control command of Kamailio 4.x does not support
running multiple Kamailio instances on one host. Nevertheless this resource agent
does allow multiple Kamailio instances per host. The result of the "kamctl"
limitation in terms of number of Kamailio server instances is that the health
check via "kamctl monitor 1" can be configured for a single Kamailio instance
only.
Please refer to the long description of this resoure agent for an example
of parameter combinations in case that multiple instances are to be
configured per cluster node.
