2021-03-16Adds ACLK-NG as fallback(#10315)Timotej S
* adds a new implementation of ACLK written almost from scratch * external dependencies only OpenSSL and JSON-C * fallback for systems where ACLK Legacy can't build (for technical or philosophical reasons) * can be forced to build by giving "--aclk-ng" to the installer
2021-02-25Remove unreachable #else directives in plugins. (#10523)vkalintiris
They are unreachable because Makefile.am will conditionally include the relevant source files iff the #ifdef's argument is defined in configure.ac.
2021-01-19Move ACLK Legacy into a subfolder (#10265)Timotej S
* move all legacy ACLK into a subfolder to make space for ACLK-NG
2020-11-24Migrate metadata log to SQLite (#10139)Stelios Fragkakis
2020-10-30allows use of system libwebsockets instead of bundled one (#9984)Timotej S
* allows usage of system libwebsockets * fixes problems that were preventing ACLK to work with LWS `4.1.` * add LWS info to buildinfo Co-authored-by: Austin S. Hemmelgarn <austin@netdata.cloud>
2020-10-20Don't check for ebpf dependencies if ebpf is disabled. (#10034)Tomáš Kopal
2020-09-24Added more stringent check for C99 support in configure script. (#9982)Austin S. Hemmelgarn
This will help ensure that people who are building on a compiler that does not support C99 get a more useful message about needing C99 and also avoid wasting time getting into the build itself.
2020-09-21Fix build for the AWS Kinesis exporting connector (#9823)Vladimir Kobal
Co-authored-by: James Mills <prologic@shortcircuit.net.au>
2020-09-16Added a way to get build configuration info from the agent. (#9913)Austin S. Hemmelgarn
* Add a way to get build configuration info from the agent. This adds a new option to the `-W` switch called 'buildinfo'. When invoked with this argument, Netdata will print it's version, the configure options, and a list of optional features and whether they are enabled or not. This is intended to serve three purposes: * It allows developers to more quickly get an idea of how Netdata was built when triaging bug reports. * It provides an easier way to validate changes to the build system that affect optional features during the development cycle. * It provides an easier way to build CI workflows that validate that building under a given set of constraints results in a feature being enabled or not. The actual implementation is a bit large but overall exceedingly simple, consisting of a set of preprocessor directives to extract optional feature state information from config.h and then a series of printf() calls to actually report this info (which should end up optimized by smart compilers due to all the arguments being compile-time constants). * Added zlib to optional libraries. * Added remaining optional plugins to buildinfo output. * Changed formatting to be more human friendly. * Add remaining optional libraries. * Fix up formatting to be even more human friendly. * Fix typo in buildinfo output. * Remove unused variable. * Fixed spelling of config.h option name. * Update daemon/buildinfo.c Co-authored-by: Markos Fountoulakis <44345837+mfundul@users.noreply.github.com> * Fix option name mismatch for libcrypto. * Update daemon/buildinfo.c Co-authored-by: Markos Fountoulakis <44345837+mfundul@users.noreply.github.com> Co-authored-by: Markos Fountoulakis <44345837+mfundul@users.noreply.github.com>
2020-09-09Fixed another typo in the libJudy bundling code. (#9904)Austin S. Hemmelgarn
* Fixed libJudy bundling code. There was a typo in the installer which was causing the configure script to not find the library. * Persist libJudy CFLAGS into build environment.
2020-09-01Added code to bundle libJudy on systems which do not provide a usable copy ↵Austin S. Hemmelgarn
of it. (#9776) * Add installer code to bundle libJudy. * Update libJudy build to work on more systems. * Added libtool to deps. * First part of configure changes - detection of library * Configure change part two: integrating flags into the build I've tested the build works and that the symbols end up correct in the compiled binary, but I have not tested that dbengine is working properly after the changes. * Add required configure options for bundling libJudy. * Bail early if a libJudy build step fails. * Added messges for specific reasons libJudy is being built. * Fix bail condition for bundling failures. We don't care about whether the cloud is required or not, just whether the user asked for a local build of libJudy or not. * Fix logic for deciding when to bundle libJudy. * Fix judy build to clean up properly if it fails.

### Summary Provide new collector parsing `/proc/slabinfo` to provide details on kernel slab structures. Asked by issue #13 (very happy for the oldest issue in backlog) ##### Component Name collectors/slabinfo.plugin ##### Additional Information This slabinfo details allows to have clues on actions done on your system. In the following screenshot, you can clearly see a `find` done on a ext4 filesystem (the number of `ext4_inode_cache` & `dentry` are rising fast), and a few seconds later, an admin issued a `echo 3 > /proc/sys/vm/drop_cached` as their count dropped.
