+ * @file
+ * Header for EVEL library
+ *
+ * This file implements the EVEL library which is intended to provide a
+ * simple wrapper around the complexity of AT&T's Vendor Event Listener API so
+ * that VNFs can use it without worrying about details of the API transport.
+ *
+ * Zero return value is success (::EVEL_SUCCESS), non-zero is failure and will
+ * be one of ::EVEL_ERR_CODES.

+# Quick Start Guide {#quickstart}
+
+# Introduction {#qs_intro}
+
+This Quick-Start section describes how to:
+
+ * Install and compile the supplied library code
+ * Integrate an existing project to use the EVEL library
+
+# Installation {#qs_install}
+
+The library is supplied as a source-code compressed-tar file. It is
+straightforward to install and build to integrate with an existing or new
+development project.
+
+## Unpack the Source Code {#qs_unpack}
+
+The file should unpacked into your development environment:
+```
+$ mkdir evel
+$ cd evel
+$ tar zxvf evel-library-package.tgz
+```
+### Satisfy Dependencies {#qs_depend}
+
+Note that all commands in this section are based on CentOS package management
+tools and you may need to substitute the appropriate tools/packages for your
+distribution, for example `apt-get` for Ubuntu.
+
+Ensure that GCC development tools are available.
+
+```
+$ sudo yum install gcc
+```
+Additionally, the library has a dependency on the cURL library, so you'll need
+the development tools for libCurl installed. (At runtime, only the runtime
+library is required, of course.)
+
+```
+$ sudo yum install libcurl-devel
+```
+If you wish to make the project documentation, then Doxygen and Graphviz are
+required. (Again, this is only in the development environment, not the runtime
+environment!)
+
+```
+$ sudo yum install doxygen graphviz
+```
+
+Note that some distributions have quite old versions of Doxygen by default and
+it may be necessary to install a later version to use all the features.
+
+If you want to build PDFs from the LaTeX you will need a texlive install.
+
+```
+$ sudo yum install texlive
+```
+
+### Test Build {#qs_build}
+Make sure that the library makes cleanly:
+
+```
+$ cd bldjobs
+$ make
+Making dependency file evel_unit.d for evel_unit.c
+Making dependency file evel_test_control.d for evel_test_control.c

+Making EVEL training
+$
+```
+You should now be able to run the demo CLI application. Since it will want to
+dynamically link to the library that you've just made, you will need to set
+your `LD_LIBRARY_PATH` appropriately first. Make sure that you specify
+your actual directory paths correctly in the following:
+
+```
+$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/centos/evel/libs/x86_64
+$ ../output/x86_64/evel_demo
+evel_demo [--help]
+ --fqdn <domain>
+ --port <port_number>
+ [--path <path>]
+ [--topic <topic>]
+ [--username <username>]
+ [--password <password>]
+ [--https]
+ [--cycles <cycles>]
+ [--nothrott]
+
+Demonstrate use of the ECOMP Vendor Event Listener API.
+
+ -h Display this usage message.
+ --help
+
+ -f The FQDN or IP address to the RESTful API.
+ --fqdn
+
+ -n The port number the RESTful API.
+ --port
+
+ -p The optional path prefix to the RESTful API.
+ --path
+
+ -t The optional topic part of the RESTful API.
+ --topic
+
+ -u The optional username for basic authentication of requests.
+ --username
+
+ -w The optional password for basic authentication of requests.
+ --password
+
+ -s Use HTTPS rather than HTTP for the transport.
+ --https
+
+ -c Loop <cycles> times round the main loop. Default = 1.
+ --cycles
+
+ -v Generate much chattier logs.
+ --verbose
+
+ -x Exclude throttling commands from demonstration.
+ --nothrott
+
+$
+```
+Assuming that all worked as expected, you are ready to start integrating with
+your application. It probably makes sense to make the LD_LIBRARY_PATH change
+above permanent by incorporating it into your `.bash_profile` file.
+
+### Project Documentation {#qs_build_docs}
+
+The source comes with its own documentation included. The documentation can be
+built using the `docs` target in the Makefile. By default this builds HTML
+and LaTeX documentation, the latter being used to prepare PDFs.
+
+To make the documentation:
+```
+$ cd bldjobs
+$ make docs
+Cleaning docs...
+Making Doxygen documentation
+$
+```
+
+There is a make target that is intended to install the documentation on a
+"team server" - it will need adaptation for your team's environment - see the
+`docs_install` target in the Makefile:
+
+```
+$ make docs_install
+Cleaning docs...
+Making Doxygen documentation
+Copying docs to team web-server...
+Enter passphrase for key '/data/home/.ssh/id_rsa':
+annotated.html 100% 8088 7.9KB/s 00:00
+arrowdown.png 100% 246 0.2KB/s 00:00
+arrowright.png 100% 229 0.2KB/s 00:00
+ ...
+$
+```
+
+# Project Integration {#qs_integrate}
+
+There are two key steps to the integration which have to be undertaken:
+
+ * Initialization/Termination of the library.
+ * Creation & posting of individual events.
+
+Additionally, it may be necessary to consider changes to the EVEL library's
+source code if assumptions made by the library are either not satisfied or
+inconvenient. In particular:
+
+ * If the project already uses libcurl then the global initialization of the
+ library should be removed from the _EVEL Library_.
+ * The _EVEL Library_ uses `syslog` for event logging. If the project uses a
+ different event logging process, then EVEL's event logging macros should be
+ rewritten appropriately.
+
+These steps are considered in the [Normal Use](@ref qs_normal_use) and
+[EVEL Adaptation](@ref qs_adaptation) sections below.
+
+## Normal Use {#qs_normal_use}
+
+The _EVEL Library_ should be integrated with your project at a per-process
+level: each process is an independent client of the ECOMP Vendor Event Listener
+API.
+
+### Initialization {#qs_initialize}
+
+The _EVEL Library_ should be initialized before the process becomes
+multi-threaded. This constraint arises from the use of libcurl which imposes
+the constraint that initialization occurs before the system is multi-threaded.
+This is described in more detail in the libcurl documentation for the
+[curl_global_init](https://curl.haxx.se/libcurl/c/curl_global_init.html)
+function.
+
+Initialization stores configuration of the Vendor Event Listener API's details,
+such as the FQDN or IP address of the service, so the initializing process must
+have either extracted this information from its configuration or have this
+information "hard-wired" into the application, so that it is available at the
+point the `evel_initialize()` function is called:
+
+```C
+ #include "evel.h"
+ ...
+ if (evel_initialize(api_fqdn,
+ api_port,
+ api_path,
+ api_topic,
+ api_secure,
+ "Alice",
+ "This isn't very secure!",
+ EVEL_SOURCE_VIRTUAL_MACHINE,
+ "EVEL demo client",
+ verbose_mode))
+ {
+ fprintf(stderr, "Failed to initialize the EVEL library!!!");
+ exit(-1);
+ }
+ ...
+```
+Once initialization has occurred successfully, the application may raise events
+and may also use the logging functions such as EVEL_INFO().
+
+Initialization is entirely local (there is no interaction with the service) so
+it is very unlikely to fail, unless the application environment is seriously
+degraded.
+
+### Event Generation {#qs_generate}
+
+Generating events is a two stage process:
+
+ 1. Firstly, the _EVEL Library_ is called to allocate an event of the correct
+ type.
+ * If this is successful, the caller is given a pointer to the event.
+ * All mandatory fields on the event are provided to this factory function
+ and are thereafter immutable.
+ * The application may add any necessary optional fields to the event, using
+ the pointer previously returned.
+ 2. The event is sent to the JSON API using the evel_post_event() function.
+ * At this point, the application relinquishes all responsibility for the
+ event:
+ * It will be posted to the JSON API, if possible.
+ * Whether or not the posting is successful, the memory used will be
+ freed.
+
+In practice this looks like:
+
+```C
+ #include "evel.h"
+ ...
+
+ /***************************************************************************/
+ /* Create a new Fault object, setting mandatory fields as we do so... */
+ /***************************************************************************/
+ fault = evel_new_fault("My alarm condition",
+ "It broke very badly",
+ EVEL_PRIORITY_NORMAL,
+ EVEL_SEVERITY_MAJOR);
+ if (fault != NULL)
+ {
+ /*************************************************************************/
+ /* We have a Fault object - add some optional fields to it... */
+ /*************************************************************************/
+ evel_fault_type_set(fault, "Bad things happen...");
+ evel_fault_interface_set(fault, "My Interface Card");
+ evel_fault_addl_info_add(fault, "name1", "value1");
+ evel_fault_addl_info_add(fault, "name2", "value2");
+
+ /*************************************************************************/
+ /* Finally, post the Fault. In practice this will only ever fail if */
+ /* local ring-buffer is full because of event overload. */
+ /*************************************************************************/
+ evel_rc = evel_post_event((EVENT_HEADER *)fault);
+ if (evel_rc != EVEL_SUCCESS)
+ {
+ EVEL_ERROR("Post failed %d (%s)", evel_rc, evel_error_string());
+ }
+ }
+ ...
+```
+### Event Types {#qs_event_types}
+
+The _EVEL Library_ supports the following types of events:
+
+ 1. Faults
+
+ These represent the **fault** domain in the event schema.
+
+ 2. Measurements
+
+ These represent the **measurementsForVfScaling** domain in the event
+ schema.
+
+ 3. Reports
+
+ This is an experimental type, designed to allow VNFs to report
+ application-level statistics unencumbered with platform measurements.
+ The formal AT&T schema has been updated to include this experimental
+ type as **measurementsForVfReporting**.
+
+ 4. Mobile Flow
+
+ These represent the **mobileFlow** domain in the event schema.
+
+ 5. Other
+
+ These represent the **other** domain in the event schema.
+
+ 6. Service Events
+
+ These represent the **serviceEvents** domain in the event schema.
+
+ 7. Signaling
+
+ These represent the **signaling** domain in the event schema.
+
+ 8. State Change
+
+ These represent the **stateChange** domain in the event schema.
+
+ 9. Syslog
+
+ These represent the **syslog** domain in the event schema.
+
+### Throttling {#qs_throttling}
+
+The _EVEL library_ supports the following command types as defined in the JSON API:
+
+ 1. commandType: throttlingSpecification
+
+ This is handled internally by the EVEL library, which stores the provided
+ throttling specification internally and applies it to all subsequent events.
+
+ 2. commandType: provideThrottlingState
+
+ This is handled internally by the EVEL library, which returns the current
+ throttling specification for each domain.
+
+ 3. commandType: measurementIntervalChange
+
+ This is handled by the EVEL library, which makes the latest measurement
+ interval available via the ::evel_get_measurement_interval function.
+ The application is responsible for checking and adhering to the latest
+ provided interval.
+
+### Termination {#qs_termination}
+
+Termination of the _EVEL Library_ is swift and brutal! Events in the buffer
+at the time are "dropped on the floor" rather than waiting for the buffer to
+deplete first.
+
+```C
+ #include "evel.h"
+ ...
+
+ /***************************************************************************/
+ /* Shutdown the library. */
+ /***************************************************************************/
+ evel_terminate();
+
+ ...
+```
+
+## EVEL Adaptation {#qs_adaptation}
+
+The _EVEL Library_ is relatively simple and should be easy to adapt into other
+project environments.
+
+### LibcURL Lifecycle
+
+There are two circumstances where initialization of libcurl may be required:
+
+ 1. If libcurl is used by the project already, and therefore already takes
+ responsibility of its initialization, then the libcurl initialization and
+ termination functions should be removed from evel_initialize() and
+ evel_terminate() respectively.
+ 2. If the project is unable to satisfy the constraint that libcurl
+ initialization takes place in a single-threaded environment at the point
+ that the _EVEL Library_ can be initialized (for example, if MT code is
+ necessary to read the configuration parameters required for
+ _EVEL Library_ initialization) then it may be necessary to extract the
+ libcurl functions and call them separately, earlier in the program's
+ operation.
+
+### Event Logging
+
+The _EVEL Library_ uses `syslog` for logging. If this is inappropriate then
+the log_debug() and log_initialize() functions should be rewritten accordingly.
+
+**Note**: it would be a really bad idea to use the _EVEL Library_ itself for this
+logging function.

+# EVEL Library Overview {#mainpage}
+
+# Introduction
+
+The ECOMP Vendor Event Listener ("EVEL") library encapsulates the use of
+AT&T's JSON API to the collector function within the ECOMP infrastructure.
+
+As such, it provides a reference implementation of the EVEL JSON API which
+can either be directly as part of a project or can be used to inform the
+independent implementation of an equivalent binding to the API in another
+development environment.
+
+This section provides an overview of the library and how it is integrated
+into the target application. If all you want is a set of instructions to
+get you started, the @ref quickstart "Quick Start" section is for you. If
+you want a more in-depth understanding of the _EVEL Library_ then this section
+provides an overview and then you can read the detailed API documentation for
+each function. The documentation for evel.h is a good starting point, since
+that defines the public API of the _EVEL Library_.
+
+# Library Structure
+
+The API is designed to be used on multi-process platforms where each process
+may be multi-threaded. Each process using this library will create an
+independent HTTP client (using libcURL). Each process will have a single
+thread running the HTTP client but that thread receives work on a
+ring-buffer from however may threads are required to implement the function.
+
+**Note**: libcurl imposes a constraint that it is initialized before
+the process starts multi-threaded operation.
+
+# Typical Usage
+
+The library is designed to be very straightforward to use and lightweight to
+integrate into projects. The only serious external dependency is on libcURL.
+
+The supplied Makefile produces a single library **libevel.so** or
+**libevel.a** which your application needs to be linked against.
+
+Each process within the application which wants to generate events needs to
+call ::evel_initialize at the start of day (observing the above warning
+about not being MT safe at this stage.) The initialization specifies the
+details of where the API is located. Management of configuration is the
+responsibility of the client.
+
+Once initialized, and now MT-safe, there are factory functions to produce
+new events:
+- Faults - ::evel_new_fault
+- Measurements - ::evel_new_measurement
+- Report - ::evel_new_report
+- State Change - ::evel_new_state_change
+- Syslog - ::evel_new_syslog
+- Other - ::evel_new_other
+- Mobile Flow - ::evel_new_mobile_flow
+
+There is also a factory function ::evel_new_mobile_gtp_flow_metrics to create
+the parameter gtp_per_flow_metrics, which is then configured and passed to the
+::evel_new_mobile_flow factory function.
+
+The event structures are initialized with mandatory fields at the point of
+creation and optional fields may be added thereafter. Once set, values in
+the structures are immutable.
+
+Once the event is prepared, it may be posted, using ::evel_post_event, at
+which point the calling thread relinquishes all responsibility for the
+event. It will be freed once successfully or unsuccessfully posted to the
+API. If, for any reason, you change your mind and don't want to post a
+created event, it must be destroyed with ::evel_free_event.
+
+Finally, at the end of day, the library can be terminated cleanly by calling
+::evel_terminate.
+
+## Example Code
+
+The following fragment illustrates the above usage:
+
+```C
+
+ if (evel_initialize(api_fqdn,
+ api_port,
+ api_path,
+ api_topic,
+ api_secure,
+ "Alice",
+ "This isn't very secure!",
+ EVEL_SOURCE_VIRTUAL_MACHINE,
+ "EVEL demo client",
+ verbose_mode))
+ {
+ fprintf(stderr, "Failed to initialize the EVEL library!!!");
+ exit(-1);
+ }
+
+ ...
+
+ fault = evel_new_fault("My alarm condition",
+ "It broke very badly",
+ EVEL_PRIORITY_NORMAL,
+ EVEL_SEVERITY_MAJOR);
+ if (fault != NULL)
+ {
+ evel_fault_type_set(fault, "Bad things happen...");
+ evel_fault_interface_set(fault, "My Interface Card");
+ evel_fault_addl_info_add(fault, "name1", "value1");
+ evel_fault_addl_info_add(fault, "name2", "value2");
+ evel_rc = evel_post_event((EVENT_HEADER *)fault);
+ if (evel_rc != EVEL_SUCCESS)
+ {
+ EVEL_ERROR("Post failed %d (%s)", evel_rc, evel_error_string());
+ }
+ }
+
+```
+
+The public API to the library is defined in evel.h. The internal APIs
+within library are defined in separate headers (<em>e.g.</em>
+evel_internal.h), but these should not need to be included by the code
+using the library.
+
+# Example Application
+
+A simple command-line application to generate events is provided as part of
+the source package (the above code fragment is taken from that application).
+
+The following illustrates its operation to a co-located "test-collector":
+```

+
+# Restrictions and Limitations
+
+## Constraint Validation
+
+The _EVEL Library_ has been designed to be production-safe code with the
+emphasis at this stage being in correctness of operation rather than
+raw performance.
+
+The API tries to check as much information as possible to avoid misuse and
+will **assert()** if constraints are not satisfied. This is likely to lead
+to the rapid discovery of coding errors by programmers, but does mean that
+the application can fail abruptly if the library is misused in any way.
+
+## Performance
+
+The default Makefile avoids aggressive optimizations so that any core-files
+are easy to interpret. Production code should use greater optimization
+levels.
+
+As described above, the HTTP client is single threaded and will run all
+transactions synchronously. As transactions are serialized, a client that
+generates a lot of events will be paced by the round-trip time.
+
+It would be a straightforward enhancement to use the multi-thread API into
+libcurl and use a pool of client threads to run transactions in parallel if
+this ever became a bottleneck.
+
+## Logging
+
+The initialization of the library includes the log verbosity. The verbose
+operation makes the library very chatty so syslog may get rather clogged
+with detailed diagnostics. It is possible to configure syslog to put these
+events into a separate file. A trivial syslog.conf file would be:
+
+```
+
+# Log all user messages so debug information is captured.
+
+user.* /var/log/debug
+```
+
+If verbose logging is enabled, the cURL library will generate information
+about the HTTP operations on **stdout**.
