2021-04-27Provide more agent analytics to posthog (#11020)Emmanuel Vasilakis
* Move statistics related functions to analytics.c * error message change, space added after if * start an analytics thread * use heartbeat instead of sleep * add late enviroment (after rrdinit) pick of some attributes * change loop * re-enable info messages * remove possible new line * log and report hits on allmetrics pages. detect if exporting engines are enabled/in use, and report them * use lowercase for analytics variables * add collectors * add buildinfo * more attributes from late environment * add new attributes to v1/info * re-gather meta data before exit. update allmetrics counters to be available in v1/info * log hits to dashboard * add mirrored hosts * added notification methods * fix spaces, proper JSON naming * add alerts, charts and metrics count * more attributes * keep the thread up, and report a meta event every 2 hours * small formating changes. Disable analytics_log_prometheus when for unit testing. Add the new attributes to the anonymous-statistics.sh.in script * applied clang-format * dont gather data again on exit * safe buffer length in snprintfz * add rrdset lock * remove show_archived * remove setenv * calculate lengths during sets

Give possibility for users to set hash table size.
2021-04-15Remove error message on netdata restart (#8685)Steve8291
When issuing a SIGTERM with `systemctl restart netdata.service` an ERROR message is created in the log for every plugin: > netdata ERROR : PLUGINSD[apps] : child pid 23901 killed by signal 15. > netdata ERROR : PLUGINSD[python.d] : child pid 23908 killed by signal 15. > netdata ERROR : PLUGINSD[nfacct] : child pid 23909 killed by signal 15. > netdata ERROR : PLUGINSD[go.d] : child pid 23899 killed by signal 15. Seems like it would be worth silencing this to an INFO message if we did a proper restart or shutdown. Also, I wasn't sure what the proper return code should be so I put it in as `return(0);`
