Centreon Broker Event Mapping

Centreon Broker uses global mapping tables for events that can be exchanged. This page lists properties available for each event type.

NEB​

Acknowledgement​

The acknowledgement of an incident means that the problem has been taken into account by a user of the monitoring service. When the user acknowledges the problem, Centreon Engine emits an acknowledgement event. This event is different in BBDO v2 and BBDO v3.

NEB::Acknowledgement​

CategoryelementID
1165537

The content of this message is serialized as follows:

PropertyTypeDescription
acknowledgement_typeshort integer0 for a host acknowledgement, 1 for a service acknowledgement.

instance_idunsigned integerInstance ID.
is_stickybooleanSticky flag.
notify_contactsbooleanNotification flag.
persistent_commentbooleanTrue if the comment is persistent.
service_idunsigned integerService ID. 0 for a host acknowledgement.
stateshort integerHost / service state.
notify_only_if_not_already_acknowledgedbooleanA notification should be sent only if not already acknowledged.

Comment​

In several situations, the user must enter a comment in the Centreon interface. When they validate it, Centreon Engine emits a comment event. This event is different in BBDO v2 and BBDO v3.

NEB::Comment​

CategoryelementID
1265538

The content of this message is serialized as follows:

PropertyTypeDescription
authorstringComment author.

service_idunsigned integerService ID. 0 if this is a host comment.
sourceshort integer0 when the comment originates from the monitoring engine (internal) or 1 when the comment comes from another source (external).

Custom variable​

A custom variable is essentially a variable with a name and a value. It often comes from Centreon Engine macros. For Centreon to work correctly, these custom variables must be sent to Centreon Broker. Each one is sent thanks to a custom variable event. This event is different in BBDO v2 and BBDO v3.

NEB::CustomVariable​

CategoryelementID
1365539

The content of this message is serialized as follows:

PropertyTypeDescription
enabledbooleanTrue if the custom variable is enabled.
host_idunsigned integerHost ID.
modifiedbooleanTrue if the variable was modified.

update_timetimeLast time at which the variable was updated.
var_typeshort integer0 for a host custom variable, 1 for a service custom variable.
valuestringVariable value.
default_valuestringThe default value of the custom var.

Custom variable status​

Custom variable status events are generated when a custom variable needs to be updated.

NEB::CustomVariableStatus​

CategoryelementID
1465540

The content of this message is serialized as follows:

PropertyTypeDescription

Event handler​

Event handlers are optional system commands (scripts or executables) that are run whenever a resource state change occurs. When such a command is configured, an event handler event is emitted by Centreon Engine. These BBDO events are usually sent when Centreon Engine is restarted or reloaded.

NEB::EventHandler​

CategoryelementID
1665542

The content of this message is serialized as follows:

PropertyTypeDescription
early_timeoutbooleanTrue if the event handler timed out.
end_timetimeTime at which the event handler execution ended.

outputstringOutput returned by the event handler.
source_idunsigned integerThe id of the source instance of this event.
destination_idunsigned integerThe id of the destination instance of this event.

Flapping status​

When the status of a resource is unstable, Centreon Engine tags it as flapping. In the past, a flapping status event was emitted in such cases. This no longer occurs. The flapping status event does not exist anymore.

Tag​

The tag is a new configuration event currently used for categories and groups.

At the moment, it is used in parallel with group events and other things, but in the near future it should be more global.

There are no tag events in BBDO v2.

Host​

This event is emitted every time a change is made to the configuration of a host and the configuration is deployed.

No Adaptive service available in BBDO v2.

Adaptive host​

This event was introduced with BBDO v3. It is emitted when a host has its configuration updated on the fly (for example with an external command).

No Adaptive host available in BBDO v2.

This is a configuration event. It defines a severity. This event was introduced with BBDO v3.

No BBDO v2 version of this event exists.

Storage​

Metric​

This event is generated by a Storage endpoint to notify that an RRD metric graph should be updated.

Storage::Metric​

CategoryelementID
31196609

The content of this message is serialized as follows:

PropertyTypeDescriptionVersion
ctimetimeTime at which the metric value was generated.
intervalunsigned integerNormal service check interval in seconds.
metric_idunsigned integerMetric ID (from the metrics table).
namestringMetric name.
rrd_lenintegerRRD retention length in seconds.
valuerealMetric value.
value_typeshort integerMetric type (1 =3D counter, 2 =3D derive, 3 =3D absolute, other =3D gauge).
is_for_rebuildbooleanSet to true when a graph is being rebuilt (see the rebuild event).
host_idunsigned integerThe id of the host this metric is attached to.
service_idunsigned integerThe id of the service this metric is attached to.

Rebuild​

Rebuild events are generated when a Storage endpoint detects that some graphs should be rebuilt. It first sends a rebuild start event (end false), then metric values (metric event with is_for_rebuild set to true) and finally a rebuild end event (end true).

This message and its principle are only available in BBDO v2. With BBDO v3, we take advantage of the power of Protobuf. To rebuild graphs, we use the event Storage::PbRebuildMessage.

Storage::Rebuild​

CategoryelementID
32196610

The content of this message is serialized as follows:

PropertyTypeDescriptionVersion
endbooleanEnd flag. Set to true if rebuild is starting, false if it is ending.
idunsigned integerID of metric to rebuild if is_index is false, or ID of index to rebuild (status graph) if is_index is true.
is_indexbooleanIndex flag. Rebuild index (status) if true, rebuild metric if false.

Remove graph​

A Storage endpoint generates a remove graph event when some graphs must be deleted.

This message and its principle are only available in BBDO v2. With BBDO v3, we take advantage of the power of Protobuf. To remove graphs, we use the event Storage::PbRemoveGraphMessage.

Storage::RemoveGraph​

CategoryelementID
33196611

The content of this message is serialized as follows:

PropertyTypeDescription
idunsigned integerIndex ID (is_index =true) or metric ID (is_index =false) to remove.
is_indexbooleanIndex flag. If true, a index (status) graph will be deleted. If false, a metric graph will be deleted.

Status​

This event is emitted by cbd when a Service Status or a Host Status event is received. It essentially contains a resource with its status.

Storage::Status​

The content of this message is serialized as follows:

PropertyTypeDescription
index_idunsigned integerIndex ID.

Index mapping​

This event is emitted by Centreon Broker when a new service configuration is received. It associates an ID to the pair (host ID/service ID). This new ID is useful for the service metrics declaration.

Storage::IndexMapping​

CategoryelementID
35196613

The content of this message is serialized as follows:

PropertyTypeDescription
index_idunsigned integerIndex ID.
host_idunsigned integerHost ID.

Rebuild Message​

This event comes with BBDO 3, when some graphs have to be rebuilt. Messages handling these rebuilds are of that type. They replace the old BBDO v2 rebuild message.

Not available with BBDO v2.

See Storage::Rebuild

Remove Graph Message​

This event comes with BBDO 3. When we want to remove graph files, we can use the centengine gRPC API and this call makes cbd generate a Storage::PbRemoveGraphMessage event. There are two possibilities concerning this event. We can remove graphs matching some index data or graphs matching some metric data. It is also possible to mix the two kinds.

Not available with BBDO v2.

See Storage::RemoveGraph

BBDO​

Version response​

This is the negotiation message used until BBDO v3.0.0. Each time a BBDO connection is established, this message is sent by the connector and by the acceptor to negotiate options.

BBDO::VersionResponse​

extensionsstringSpace-separated string of extensions supported by the peer sending this version_response packet.

Ack​

Usually, a BBDO sender sends events and a BBDO receiver consumes events. But the sender keeps events until the receiver tells it they have been handled. To do that, the receiver emits an Ack message with the number of events already handled.

22131074

The content of this message is serialized as follows:

PropertyTypeDescriptionVersion
acknowledged eventsunsigned integerNumber of acknowledged events. Only used by "smart" clients (i.e able to acknowledge events). Not to be used by dumb clients.

Stop​

When one side of a BBDO connection is going to exit, it emits a Stop event so that if the other side has events already handled it can send an Ack event.
