2021-07-07ACLK-NG New Cloud NodeInstance related msgs (#11234)Timotej S
Adds new cloud arch NodeInstance messages as per design. Co-authored-by: Stelios Fragkakis <52996999+stelfrag@users.noreply.github.com>
2021-07-07Add hop count for children (#11311)Stelios Fragkakis
2021-05-31Provide UTC offset in seconds and edit health config command (#11051)Emmanuel Vasilakis
* add abbreviated timezone, utc offset in seconds, and edit health alarm command rebased * formating * use str2i instead of atoi
2021-05-24Remove unecessary relative paths when including headers. (#11124)vkalintiris
Currently, we add the repository's top-level dir in the compiler's header search path. This means that code in every top-level directory within the repo can include headers sibling top-level directories. This patch makes header inclusion consistent when it comes to files that are included from sibling top-level directories within the repo.

2020-08-19Fix long stats.d chart names (thanks to @vince-lessbits) (#9783)Andrew Moss
The read buffer in the streaming receiver was too small to allow the longest lines in the plugins.d protocol to be reassembled.
2020-08-11Remove broken optimization in the sender thread (#9703)Andrew Moss
The sender thread avoided locking the circular buffer to check if there was outstanding data on the connection. The condition it needs (unsent data) grows monotonically w.r.t. other threads as the collectors can add data but only this thread can remove it. However, it cached the pointer into the buffer as a side-effect and then reused it later during the transmission. This fails if the buffer is resized by a collector thread. Peeking at the buffer sizes without locking could fail in the same situation. The optimization is removed and the sender thread now locks the mutex before checking the buffer, throws away the data buffer pointer and releases the mutex over the poll() operation. It then reacquires the mutex and checks the buffer size and data pointer again when it performs the send.

2020-06-29Fix children version on stream (#9438)thiagoftsm
Store Netdata child version instead parent version inside `HOST` structure.
2020-06-22Fixed concurrency bug in health sending HOST VARIABLE to receiver (#9396)thiagoftsm
The recent changes to the streaming component wipe the send buffer when the mutex is acquired to prevent stale data and expose concurrency bugs. The callback from health was called from another thread to write into the stream buffer without any protection. This protects the access to the buffer.
2020-06-19Fixes the race-hazard in streaming during the shutdown sequence (#9370)Andrew Moss
The streaming component detects when a receiver stream has closed, and stops an attached sender on the same host. This is to support proxy configurations where the stream is passed through. During the shutdown sequence, once netdata_exit has been set no thread should touch any RRDHOST structure as the non-static threads are not joined before the database shuts down. The destruction of the thread state has been separated from the cleanup and can be called from two points. If the thread can detach itself from the host (i.e. it is not during the shutdown sequence) then it does so and destroys the state. During shutdown the thread leaves the state intact so that it can be destroyed during the host destruction, and the host destruction now cancels the thread to ensure a consistent sequence of events.

Removed uses of the host lock that could deadlock senders and replaced with the new fine-grained mutex.
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.
