2020-05-12Fix the latency issue on the ACLK and suppress the diagnostics (#8992)Andrew Moss
The on-connect payloads were large enough to trigger a massive increase in latency on the link and prevent chart updates due to head-of-line blocking. The default window detection in libwebsockets was under-reporting the size of the available window in the network. Overwritten with some sensible values. The large volume of ACLK per-message info-logging is not produced unless the agent is compiled with NETDATA_INTERNAL_CHECKS. The logging now includes latency measurements on the link.

2020-04-22Add http headers to responses (#8760)Andrew Moss
The MQTT payloads for responses to API requests from the cloud now include a headers field with the raw http headers encoded into unicode. This exposes the `Date` and `Expired` fields to the cloud backend.

Improved ACLK memory management and shutdown sequence
2020-04-08Add session-id using connect timestamp (#8633)Andrew Moss
Added a session-id to the ACLK messages to overcome a problem with the LWT timestamp being out of sequence with the rest of the message flow.
2020-04-03Fix Coverity defects (#8579)Andrew Moss
Fix Coverity CID355287 and CID355289: technically it is a false-positive but it is easier to put a pattern in the code that they can recognise as a sanitizer. The compiler will remove it during optimization. Fix CID353973: the security condition is unlikely to occur but we can avoid it completely. Fix resource leak from CID 355286 and CID 355288. Fixing new resource leak introduced by a previous commit (CID355449)
2020-03-31Switching over to soft feature flag (#8545)Andrew Moss
Preparing for the cloud release. This changes how we handle the feature flag so that it no longer requires installer switches and can be set from the config file. This still requires internal access to use and is not ready for public access yet.
2020-03-31Improve the behavior of claiming (#8516)Andrew Moss
The default cloud url has been updated to app.netdata.cloud ready for the release. The claiming process now checks the current user executing claiming and refuses to perform the claim for the wrong user. If the current UID is 0 then claiming proceeds but the file ownership is adjusted to be the correct netdata user. The default expected user is `netdata` unless the script can identify the user from the current configuration. After the claiming script is executed the CLI is used to reload the claiming state.

2020-03-17Fix outstanding problems in claiming and add SOCKS5 support. (#8406)Andrew Moss
This commit fixes the known problems in claiming: incorrect reports of success, better treatment of error code and improved visibility of what the script is doing. There has been extensive testing against both environments to check that it works. The socks5 proxy support has been integrated and works for both methods of calling the claiming script. Co-authored-by: Timotej Šiškovič <timotej@netdata.cloud>

2020-03-14Improved the performance of the ACLK. (#8391) (#8401)Andrew Moss
* Switched back to lws internal scheduler, small fragment size. * Fixing comment from review
2020-03-14Improving the ACLK performance - initial changes (#8399)Andrew Moss
Add an inspection point for VerneMQ in the local dev env. Remove the bottleneck in sending websocket messages, at the expense of increased CPU-load. Fixed the message encoding. Added support for stress testing - it is still enabled in the main loop so will fire stress-testing payloads when the ACLK is established. Next patch will integrate the socket polling properly to reduce the CPU overhead and remove the stress testing payloads.
2020-03-13ACLK: Improved the agent "pop-corning" phase (#8398)Stelios Fragkakis
* Ignore the cloud commands when the agent is initializing * Tune the agent popcorning * Reorder waiting msg, stable timeout back to 10 seconds * Moved checks for popcorning to the calling functions for code clarity
