+== Micrometer Observation Example
+
+=== Introduction
+
+This example shows how to use Camel with Micrometer Observation to create observations for
+incoming and outgoing Camel messages.
+
+For Metrics we are using Micrometer Core, for Tracing we're using Micrometer Tracing with Brave.
+
+The example includes four sub maven modules that implement
+
+* client
+* service1
+* service2
+* loggingtracer
+
+Where client -> service1 -> service2 using HTTP.
+
+=== Build
+
+You will need to compile this example first:
+
+[source,sh]
+----
+$ mvn compile
+----
+
+=== Run the example
+
+Then using three different shells and run service1 and service2 before
+the client. These services use an annotation _CamelObservation_ to
+indicate that the service should be traced.
+
+[source,sh]
+----
+$ cd service1
+$ mvn compile spring-boot:run
+----
+
+When service1 is ready then start service2
+
+[source,sh]
+----
+$ cd service2
+$ mvn compile spring-boot:run
+----
+
+And then start the client that calls service1 every 30 seconds.
+
+[source,sh]
+----
+$ cd client
+$ mvn compile spring-boot:run
+----
+
+The client application explicitly instantiates and initializes the
+Micrometer Observation Tracer with the _CamelContext_.
+
+The shells will show _SPAN FINISHED_ messages indicating what spans have
+been reported from the client and two services.
+
+=== Outcome
+
+You should get a trace view similar to this one
+
+image::adoc/img/trace.jpeg[]
+
+You will get Camel related metrics similar to these
+
+Example for server application

+Meter name [trigger.active], type [LONG_TASK_TIMER] - measurements [Measurement{statistic='ACTIVE_TASKS', value=0.0}, Measurement{statistic='DURATION', value=0.0}]
+Meter name [camel.component], type [TIMER] - measurements [Measurement{statistic='COUNT', value=1.0}, Measurement{statistic='TOTAL_TIME', value=3.154452898}, Measurement{statistic='MAX', value=3.154452898}]
+Meter name [camel.component.active], type [LONG_TASK_TIMER] - measurements [Measurement{statistic='ACTIVE_TASKS', value=0.0}, Measurement{statistic='DURATION', value=0.0}]

+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and

+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the

+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only

+ institute patent litigation against any entity (including a
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
+ or a Contribution incorporated within the Work constitutes direct
+ or contributory patent infringement, then any patent licenses
+ granted to You under this License for that Work shall terminate

+
+ (b) You must cause any modified files to carry prominent notices
+ stating that You changed the files; and

+ (d) If the Work includes a "NOTICE" text file as part of its

+ include a readable copy of the attribution notices contained
+ within such NOTICE file, excluding those notices that do not
+ pertain to any part of the Derivative Works, in at least one
+ of the following places: within a NOTICE text file distributed
+ as part of the Derivative Works; within the Source form or
+ documentation, if provided along with the Derivative Works; or,
+ within a display generated by the Derivative Works, if and
+ wherever such third-party notices normally appear. The contents
+ of the NOTICE file are for informational purposes only and
+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or
+ for any such Derivative Works as a whole, provided Your use,
+ reproduction, and distribution of the Work otherwise complies with
+ the conditions stated in this License.
+
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
+ any Contribution intentionally submitted for inclusion in the Work
+ by You to the Licensor shall be under the terms and conditions of

+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ implied, including, without limitation, any warranties or conditions
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+ PARTICULAR PURPOSE. You are solely responsible for determining the
+ appropriateness of using or redistributing the Work and assume any
+ risks associated with Your exercise of permissions under this License.
+
+ 8. Limitation of Liability. In no event and under no legal theory,
+ whether in tort (including negligence), contract, or otherwise,
+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only
+ on Your own behalf and on Your sole responsibility, not on behalf
+ of any other Contributor, and only if You agree to indemnify,
+ defend, and hold each Contributor harmless for any liability
+ incurred by, or claims asserted against, such Contributor by reason
+ of your accepting any such warranty or additional liability.
