2023-07-06Code reorg and cleanup - enrichment of /api/v2 (#15294)Costa Tsaousis
* claim script now accepts the same params as the kickstart * rewrote buildinfo to unify all methods * added cloud unavailable in cloud status * added all exporters * renamed httpd to h2o * rename ENABLE_COMPRESSION to ENABLE_LZ4 * rename global variable * rename ENABLE_HTTPS to ENABLE_OPENSSL * fix coverity-scan for openssl * add lz4 to coverity-scan * added all plugins and most of the features * added all plugins and most of the features * generalize bitmap code so that we can have any size of bitmaps * cleanup * fix compilation without protobuf * fix compilation with others allocators * fix bitmap * comprehensive bitmaps unit test * bitmap as macros * added developer mode * added system info to build info * cloud available/unavailable * added /api/v2/info * added units and ni to transitions * when showing instances and transitions, show only the instances that have transitions * cleanup * add missing quotes * add anchor to transitions * added more to build info * calculate retention per tier and expose it to /api/v2/info * added currently collected metrics * do not show space and retention when no numbers are available * fix impossible overflow * Add function for transitions and execute callback * In case of error, reset and try next dictionary entry * Fix error message * simpler logic to maintain retention per tier * /api/v2/alert_transitions * Handle case of recipient null Convert after and before to usec * Add classification, type and component * working /api/v2/alert_transitions * Fix query to properly handle context and alert name * cleanup * Add search with transition * accept transition in /api/v2/alert_transitions * totaly dynamic facets * fixed debug info * restructured facets * cleanup; removal of options=transitions * updated alert entries flags * method to exec * Return also exec run timestamp Temp table cleanup only when we don't execute with a transition * cleanup obsolete anchor parameter * Add sql_get_alert_configuration function * added options=config to alert_transitions * added /api/v2/alert_config * preliminary work for /api/v2/claim * initialize variables; do not expose expected retention if no disk space info is available; do not report aclk as initializing when not claimed * fix claim session key filename * put a newline into the session key file * more progress on claiming * final /api/v2/claim endpoint * after claiming, refresh our state at the output * Fix query to fetch config * Remove debug log * add configuration objects * add configuration objects - fixed * respect the NETDATA_DISABLE_CLOUD env variable * NETDATA_DISABLE_CLOUD env variable sets the default, but the config sets the final value * use a new claimed_id on every claiming * regenerate random key on claiming and wait for online status * ignore write() return value when writing a newline * dont show cloud status disabled when claimed_id is missing * added ctx to alert instances * cleanup config and transitions from /api/v2/alerts * fix unused variable * in /api/v2/alert_config show 1 config without an array * show alert values conditionally, by appending options=values * When storing host info if the key value is empty, store unknown * added options=summary to control when the alerts summary is shown * increased http_api_v2 to version 5 * claming random key file is now not world readable * added local-listeners binary that detects all the listening ports, their IPs and their command lines --------- Co-authored-by: Stelios Fragkakis <52996999+stelfrag@users.noreply.github.com>

2023-06-29Optimizations part 2 (#15280)Costa Tsaousis
* make all pluginsd functions inline, instead of function pointers * dynamic MRG partitions based on the number of CPUs * report the right size of the MRG * prevent invalid read on pluginsd exit * faster service_running() check; fix compiler warnings; shutdown replication after streaming to prevent crash on shutdown * sender is now using a spinlock * rrdcontext uses spinlock * replace select() with poll() * signed calculation of threads * disable read-ahead on jnfv2 files during scan
