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. +[Turtles all the way down...](https://en.wikipedia.org/wiki/Turtles_all_the_way_down) + +

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": +``` +$ ./evel_demo --fqdn 127.0.0.1 --port 30000 --path vendor_event_listener --topic example_vnf --verbose +./evel_demo built Feb 26 2016 18:14:48 +* About to connect() to 169.254.169.254 port 80 (#0) +* Trying 169.254.169.254... * Timeout +* connect() timed out! +* Closing connection #0 +* About to connect() to 127.0.0.1 port 30000 (#0) +* Trying 127.0.0.1... * connected +* Connected to 127.0.0.1 (127.0.0.1) port 30000 (#0) +* Server auth using Basic with user 'Alice' +> POST /vendor_event_listener/eventListener/v1/example_vnf HTTP/1.1 +Authorization: Basic QWxpY2U6VGhpcyBpc24ndCB2ZXJ5IHNlY3VyZSE= +User-Agent: libcurl-agent/1.0 +Host: 127.0.0.1:30000 +Accept: */* +Content-type: application/json +Content-Length: 510 + +* HTTP 1.0, assume close after body +< HTTP/1.0 204 No Content +< Date: Fri, 04 Mar 2016 15:37:22 GMT +< Server: WSGIServer/0.1 Python/2.6.6 +< +* Closing connection #0 +* About to connect() to 127.0.0.1 port 30000 (#0) +* Trying 127.0.0.1... * connected +* Connected to 127.0.0.1 (127.0.0.1) port 30000 (#0) +* Server auth using Basic with user 'Alice' +> POST /vendor_event_listener/eventListener/v1/example_vnf HTTP/1.1 +Authorization: Basic QWxpY2U6VGhpcyBpc24ndCB2ZXJ5IHNlY3VyZSE= +User-Agent: libcurl-agent/1.0 +Host: 127.0.0.1:30000 +Accept: */* +Content-type: application/json +Content-Length: 865 + +* HTTP 1.0, assume close after body +< HTTP/1.0 204 No Content +< Date: Fri, 04 Mar 2016 15:37:22 GMT +< Server: WSGIServer/0.1 Python/2.6.6 +< +* Closing connection #0 +* About to connect() to 127.0.0.1 port 30000 (#0) +* Trying 127.0.0.1... * connected +* Connected to 127.0.0.1 (127.0.0.1) port 30000 (#0) +* Server auth using Basic with user 'Alice' +> POST /vendor_event_listener/eventListener/v1/example_vnf HTTP/1.1 +Authorization: Basic QWxpY2U6VGhpcyBpc24ndCB2ZXJ5IHNlY3VyZSE= +User-Agent: libcurl-agent/1.0 +Host: 127.0.0.1:30000 +Accept: */* +Content-type: application/json +Content-Length: 2325 + +* HTTP 1.0, assume close after body +< HTTP/1.0 204 No Content +< Date: Fri, 04 Mar 2016 15:37:22 GMT +< Server: WSGIServer/0.1 Python/2.6.6 +< +* Closing connection #0 +^C + +Interrupted - quitting! +$ +``` + +# 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**. + diff --git a/veslibrary/ves_clibrary/evel/evel-library/code/evel_library/ring_buffer.c b/veslibrary/ves_clibrary/evel/evel-library/code/evel_library/ring_buffer.c new file mode 100644 index 0000000..8080e02 --- /dev/null +++ b/veslibrary/ves_clibrary/evel/evel-library/code/evel_library/ring_buffer.c @@ -0,0 +1,192 @@ +/*************************************************************************//** + * + * Copyright © 2017 AT&T Intellectual Property.
