2020-06-03Fix bugs in streaming and enable support for gap filling (#9214)Andrew Moss
This PR adds (inactive) support that we will use to fill the gaps on chart when a receiving agent goes offline and the sender reconnects. The streaming component has been reworked to make the connection bi-directional and fix several outstanding bugs in the area. * Fixed an incorrect case of version negotiation. Removed fatal() on exhaustion of fds. * Fixed cases that fell through to polling the socket after closing. * Fixed locking of data related to sender and receiver in the host structure. * Added fine-grained locks to reduce contention. * Added circular buffer to sender to prevent starvation in high-latency conditions. * Fixed case where agent is a proxy and negotiated different streaming versions with sender and receiver. * Changed interface to new parser to put the buffering code in streaming. * Fixed the bug that stopped senders from reconnecting after their socket times out - this was part of the scaling fixes that provide an early shortcut path for rejecting connections without lock contention. * Uses fine-grained locking and a different approach to thread shutdown instead. * Added liveness detection to connections to allow selection of the best connection.

2019-10-17feat(reaper): Add process reaper support (#7059)Steven Hartland
##### Summary Add a child process reaper to the main netdata app if running as init (pid = 1). This prevents zombie processes when a child is re-parented to netdata when its running in a container. Also: * Few style cleanups to match surrounding code. Fixes: #6033 ##### Component Name netdata binary ##### Additional Information This re-purposes old commented out code in `popen.c`, which already implemented part of the required process tracking. Without this on a standard netdata docker install we saw at least one zombie `timeout` process straight after the container was started.
2019-10-11Disable slabinfo plugin by default (#7056)Vladimir Kobal
2019-09-18Collector slabinfo (#6800)Adrien Mahieux
### 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.

2019-07-29Add configurable default locations for trusted CA certificates (#6549)thiagoftsm
* sslcertificate: Trust certificate The netdata could not allow invalid certificate or certificate with invalid chain this commit fixes this! * sslcertificate: Changing name We are binging the same names used by the OpenSSL library to simplify the understand of the parameters * sslcertificate: Name changes and explicity directory This commit fix the problem with Streams and rename correctly the files in the option, it also uses stat to define the existence of a file * sslcertificate: Documentation Fix grammar for the newest section in the documentation * sslcertificate: Rename variables The old variables did not represent well what they are doing, so it was renamed
2019-07-25Fix parsing SSL ACL along with others (#6468)thiagoftsm
* sslstream: ACL parser It was noticed in the issue 6457 that the some ACLs were not parsing correctly when they were along SSL acl, this commit fixes this' * sslstream: remove comments This commit removes the comments that were present while I was testing the code * sslstream: Tests This commit adds ACL tests to check the Netdata response to them * sslstream: Tests Fix the extension to upload the files * sslstream: more tests In this commit I am bringing more tests, including the ssl tests' * sslstream: leading space Remove leading space from variable that was creating problem with shellcheck * sslstream: glob Remove special character from script * sslstream: Makefile The Makefile diretives were pointed to wrong files * sslstream: Missing stream encrypt This commit solves the problem of the stream not be encrypted, but it is not the final solution, because the parser made is incomplete. * sslstream: Finish encrypt channel This commit brings the step that I was missing, the complete encryptation in the communication between Master and Slave * sslstream: Fix argument in script After the latest tests, it was verified that two arguments given to a function inside the script were not correct, with this PR I am fixing this! * sslstream: Fix argument in info Instead to call a function to deliver an integer I was passing a size_t value. Only cmake showed this, but not in my clion! :/ * sslstream: Fix redirect When we were having different SSL configuration, the system were not applying the option for all * sslstream: Update documentation Our documentation was not clear about the rules according our code so I am updating the text to explain for the users * sslstream: Adjust script With this last commit, I am adjusting the tests to avoid false positive * sslstream: Missing elif The previous commit had a missing elif in the shell script * sslstream: Split ports Before this commit Netdata was having SSL as a global option, now it has as a real ACL. * sslstream: reduce context The stream variable will not be affected in the master side, it is only necessary on the slave side, so I am reducing the context of it * sslstream: Force SSL When the user has certificate and he does not set any SSL flag, it is necessary to append the SSL=force flag * sslstream: Default flag It is necessary to have a default flag when the SSL flags are not SET * sslstream: remove comments Remove comments from the scrip * sslstream: moving flag It is better the flag to be set inside socket instead everytime there is a new connection * sslstream: documentation Fix a sentence in the web/server/README.md

2019-03-13Fix memory leaks (#5604)Vladimir Kobal
2019-03-05Minor fixes around plugin_directories initialization (#5536)Paul Katsoulakis
* Daemon minor cleanups: 1) pull in plugin directories logic, inside the pluginsd where it belongs and call a method from the daemon to do so, 2) Magic numbers are evil, give a meaningful definition for that plugin directories retrieval * Rename netdata_configured_plugins_dir -> netdata_configured_primary_plugins_dir. We allow multiple plugin directories and this is actually the primary (or stock?) directory, just make it clear to avoid confusion * In this new wrapper, just return whatever the string splitter would return * Reduce the scope - consider moving this to somewhere else in a common place if needed by other modules later
