Available as of Fuse Mediation Router 2.3
The Nagios component allows you to send passive checks to Nagios.
nagios://host[:port][?Options]
Fuse Mediation Router provides two abilities with the Nagios component. You can send passive check messages by sending a message to its endpoint. Fuse Mediation Router also provides a EventNotifer which allows you to send notifications to Nagios.
Name | Default Value | Description |
---|---|---|
host
|
none | This is the address of the Nagios host where checks should be send. |
port
|
The port number of the host. | |
password
|
Password to be authenticated when sending checks to Nagios. | |
connectionTimeout
|
5000 | Connection timeout in millis. |
timeout
|
5000 | Sending timeout in millis. |
nagiosSettings
|
To use an already configured
com.googlecode.jsendnsca.core.NagiosSettings object. |
|
sendSync
|
true
|
Whether or not to use synchronous when sending a passive check. Setting it to
false will allow Fuse Mediation Router to continue routing the message and the
passive check message will be send asynchronously. |
Name | Description |
---|---|
CamelNagiosHostName
|
This is the address of the Nagios host where checks should be send. This header will override any existing hostname configured on the endpoint. |
CamelNagiosLevel
|
This is the severity level. You can use values CRITICAL, WARNING,
OK . Fuse Mediation Router will by default use OK . |
CamelNagiosServiceName
|
The servie name. Will default use the CamelContext name. |
You can send a message to Nagios where the message payload contains the message. By
default it will be OK
level and use the CamelContext name as the service name. You can overrule these values using headers
as shown above.
For example we send the Hello Nagios
message to Nagios as
follows:
template.sendBody("direct:start", "Hello Nagios"); from("direct:start").to("nagios:127.0.0.1:5667?password=secret").to("mock:result");
To send a CRITICAL
message you can send the headers such as:
Map headers = new HashMap(); headers.put(NagiosConstants.LEVEL, "CRITICAL"); headers.put(NagiosConstants.HOST_NAME, "myHost"); headers.put(NagiosConstants.SERVICE_NAME, "myService"); template.sendBodyAndHeaders("direct:start", "Hello Nagios", headers);
The Nagios component also provides an EventNotifer which you can use to send events to Nagios. For example we can enable this from Java as follows:
NagiosEventNotifier notifier = new NagiosEventNotifier(); notifier.getConfiguration().setHost("localhost"); notifier.getConfiguration().setPort(5667); notifier.getConfiguration().setPassword("password"); CamelContext context = ... context.getManagementStrategy().addEventNotifier(notifier); return context;
In Spring XML its just a matter of defining a Spring bean with the type
EventNotifier
and Fuse Mediation Router will pick it up as documented here: Advanced configuration of
CamelContext using Spring.
