Nagios Page edited by Claus Ibsen Nagios Available as of Camel 2.3 The Nagios component allows you to send passive checks to Nagios. URI format nagios://host[:port][?Options] Camel provides two abilities with the Nagios component. You can send passive check messages by sending a message to its endpoint. Camel also provides a EventNotifer which allows you to send notifications to Nagios. Options 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 Camel to continue routing the message and the passive check message will be send asynchronously. Headers 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. Camel will by default use OK. CamelNagiosServiceName The servie name. Will default use the CamelContext name. Sending message examples 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); Using NagiosEventNotifer 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 Camel will pick it up as documented here: Advanced configuration of CamelContext using Spring.
