* dictionary internals isolation
* more dictionary cleanups
* added unit test
* we should use DICT internally
* disable cups in cmake
* implement DICTIONARY with Judy arrays
* operational JUDY implementation
* JUDY cleanup
* JUDY summary added
* JudyHS implementation with double linked list
* test negative searches too
* optimize destruction
* optimize set to insert first without lookup
* updated stats
* code cleanup; better organization; updated info
* more code cleanup and commenting
* more cleanup, renames and comments
* fix rename
* more cleanups
* use Judy.h from system paths
* added foreach traversal; added flag to add item in front; isolated locks to their own functions; destruction returns the number of bytes freed
* more comments; flags are now 16-bit
* completed unittesting
* addressed comments and added reference counters maintainance
* added unittest in main; tested removal of items in front, back and middle
* added read/write walkthrough and foreach; allowed walkthrough and foreach in write mode to delete the current element (used by cups.plugin); referenced counters removed from the API
* DICTFE.name should be const too
* added API calls for exposing all statistics
* dictionary flags as enum and reference counters as atomic operations
* more comments; improved error handling at unit tests
* added functions to allow unsafe access while traversing the dictionary with locks in place
* check for libcups in cmake
* added delete callback; implemented statsd with this dictionary
* added missing dfe_done()
* added alternative implementation with AVL
* added documentation
* added comments and warning about AVL
* dictionary walktrhough on new code
* simplified foreach; updated docs
* updated docs
* AVL is much faster without hashes
* AVL should follow DBENGINE

(#12911)
|

|
|
|
|
* Remove error (no real value)
* Add a parameter to create an in-memory database for stress testing
* Add a new parameter to the stresstest command to set the number of deisred libuv worker threads
|
|
* initial version of worker utilization
* working example
* without mutexes
* monitoring DBENGINE, ACLKSYNC, WEB workers
* added charts to monitor worker usage
* fixed charts units
* updated contexts
* updated priorities
* added documentation
* converted threads to stacked chart
* One query per query thread
* Revert "One query per query thread"
This reverts commit 6aeb391f5987c3c6ba2864b559fd7f0cd64b14d3.
* fixed priority for web charts
* read worker cpu utilization from proc
* read workers cpu utilization via /proc/self/task/PID/stat, so that we have cpu utilization even when the jobs are too long to finish within our update_every frequency
* disabled web server cpu utilization monitoring - it is now monitored by worker utilization
* tight integration of worker utilization to web server
* monitoring statsd worker threads
* code cleanup and renaming of variables
* contrained worker and statistics conflict to just one variable
* support for rendering jobs per type
* better priorities and removed the total jobs chart
* added busy time in ms per job type
* added proc.plugin monitoring, switch clock to MONOTONIC_RAW if available, global statistics now cleans up old worker threads
* isolated worker thread families
* added cgroups.plugin workers
* remove unneeded dimensions when then expected worker is just one
* plugins.d and streaming monitoring
* rebased; support worker_is_busy() to be called one after another
* added diskspace plugin monitoring
* added tc.plugin monitoring
* added ML threads monitoring
* dont create dimensions and charts that are not needed
* fix crash when job types are added on the fly
* added timex and idlejitter plugins; collected heartbeat statistics; reworked heartbeat according to the POSIX
* the right name is heartbeat for this chart
* monitor streaming senders
* added streaming senders to global stats
* prevent division by zero
* added clock_init() to external C plugins
* added freebsd and macos plugins
* added freebsd and macos to global statistics
* dont use new as a variable; address compiler warnings on FreeBSD and MacOS
* refactored contexts to be unique; added health threads monitoring

allocations (#12841)
* fix mismatches of the use of the z functions for allocations

* fixed memory leak on exit of plugins.d parser
* fixed memory leak on plugins and streaming receiver threads exit
* fixed compiler warnings

* reworked for clarity and finally fixed the bug of allocating memory beyond the page size
* further optimize allocation step to minimize the number of allocations made
* implement strdup with memcpy instead of strcpy
* added documentation
* prevent an uninitialized use of owa

* align on the size of pointers
* forgotten freez()
* removed not needed memcpys
* give unique names to global variables to avoid conflicts with system definitions

They are used extensively throughout our code base, and not having
support for them does not generate a thread-safe agent.
