Currently, we add the repository's top-level dir in the compiler's
header search path. This means that code in every top-level directory
within the repo can include headers sibling top-level directories.
This patch makes header inclusion consistent when it comes to files
that are included from sibling top-level directories within the repo.
|
|
These fields made our headers incompatible with C++, because `class` is
a reserved keyword.

##### Summary
This is implementation of a prerequisite for the requested feature #6536 (Generate an overall status badge/chart for the health of category)
##### Component Name
web/api/
health/
##### Details
Provide a new, `alarm_count` API call that returns the total number of alarms for given contexts and alarm states. Default is the total number of raised alarms, for all contexts.
|
|
##### Summary
Implements feature #6054
Now requests like
http://localhost:19999/api/v1/chart?chart=example.random
http://localhost:19999/api/v1/data?chart=example.random&options=jsonwrap&options=showcustomvars
- return chart variables in their responses. Chart variables include only those with options set to RRDVAR_OPTION_CUSTOM_CHART_VAR
- for /api/v1/data requests chart variables are returned when parameter options=jsonwrap and options=showcustomvars

This PR was created to fix #3414, here I am completing the job initiated by Christopher, among the newest features that we are bring we have
JSON inside the core - We are bringing to the core the capacity to work with JSON files, this is available either using the JSON-C library case it is present in the system or using JSMN library that was incorporated to our core. The preference is to have JSON-C, because it is a more complete library, but case the user does not have the library installed we are keeping the JSMN for we do not lose the feature.
Health LIST - We are bringing more one command to the Health API, now with the LIST it is possible to get in JSON format the alarms active with Netdata.
Health reorganized - Previously we had duplicated code in different files, this PR is fixing this (Thanks @cakrit !), the Health is now better organized.
Removing memory leak - The first implementation of the json.c was creating SILENCERS without to link it in anywhere. Now it has been linked properly.
Script updated - We are bringing some changes to the script that tests the Health.
This PR also fixes the race condition created by the previous new position of the SILENCERS creation, I had to move it to daemon/main.c, because after various tests, it was confirmed that the error could happen in different parts of the code, case it was not initialized before the threads starts.
Component Name
health directory
health-cmd
