DYNCFG: dynamically configured alerts (#16779)
* cleanup alerts * fix references * fix references * fix references * load alerts once and apply them to each node * simplify health_create_alarm_entry() * Compile without warnings with compiler flags: -Wall -Wextra -Wformat=2 -Wshadow -Wno-format-nonliteral -Winit-self * code re-organization and cleanup * generate patterns when applying prototypes; give unique dyncfg names to all alerts * eval expressions keep the source and the parsed_as as STRING pointers * renamed host to node in dyncfg ids * renamed host to node in dyncfg ids * add all cloud roles to the list of parsed X-Netdata-Role header and also default to member access level * working functionality * code re-organization: moved health event-loop to a new file, moved health globals to health.c * rrdcalctemplate is removed; alert_cfg is removed; foreach dimension is removed; RRDCALCs are now instanciated only when they are linked to RRDSETs * dyncfg alert prototypes initialization for alerts * health dyncfg split to separate file * cleanup not-needed code * normalize matches between parsing and json * also detect !* for disabled alerts * dyncfg capability disabled * Store alert config part1 * Add rrdlabels_common_count * wip health variables lookup without indexes * Improve rrdlabels_common_count by reusing rrdlabels_find_label_with_key_unsafe with an additional parameter * working variables with runtime lookup * working variables with runtime lookup * delete rrddimvar and rrdfamily index * remove rrdsetvar; now all variables are in RRDVARs inside hosts and charts * added /api/v1/variable that resolves a variable the same way alerts do * remove rrdcalc from eval * remove debug code * remove duplicate assignment * Fix memory leak * all alert variables are now handled by alert_variable_lookup() and EVAL is now independent of alerts * hide all internal structures of EVAL * Enable -Wformat flag Signed-off-by: Tasos Katsoulas <tasos@netdata.cloud> * Adjust binding for calculation, warning, critical * Remove unused macro * Update config hash id * use the right info and summary in alerts log * use synchronous queries for alerts * Handle cases when config_hash_id is missing from health_log * remove deadlock from health worker * parsing to json payload for health alert prototypes * cleaner parsing and avoiding memory leaks in case of duplicate members in json * fix left-over rename of function * Keep original lookup field to send to the cloud Cleanup / rename function to store config Remove unused DEFINEs, functions * Use ac->lookup * link jobs to the host when the template is registered; do not accept running a function without a host * full dyncfg support for health alerts, except action TEST * working dyncfg additions, updates, removals * fixed missing source, wrong status updates * add alerts by type, component, classification, recipient and module at the /api/v2/alerts endpoint * fix dyncfg unittest * rename functions * generalize the json-c parser macros and move them to libnetdata * report progress when enabling and disabling dyncfg templates * moved rrdcalc and rrdvar to health * update alarms * added schema for alerts; separated alert_action_options from rrdr_options; restructured the json payload for alerts * enable parsed json alerts; allow sending back accepted but disabled * added format_version for alerts payload; enables/disables status now is also inheritted by the status of the rules; fixed variable names in json output * remove the RRDHOST pointer from DYNCFG * Fix command field submitted to the cloud * do not send updates to creation requests, for DYNCFG jobs --------- Signed-off-by: Tasos Katsoulas <tasos@netdata.cloud> Co-authored-by: Stelios Fragkakis <52996999+stelfrag@users.noreply.github.com> Co-authored-by: Tasos Katsoulas <tasos@netdata.cloud> Co-authored-by: ilyam8 <ilya@netdata.cloud>
