2018-10-10	Improve data ingestion reliability and functionality	earrage	7	-81/+121
	- Modify deployment namespace to clover-system and account for cassandra moving to the clover-system namespace - Increase k8s compute resource assigned to cassandra to deal with performance issues - Add additional fields (user-agent, request/response size, status codes) to span schema definition and modify primary keys - Improve exception handling to prevent collect process from crashing - Minor changes to support tracing/monitoring with Istio 1.0 - Inhibit logging for debug messages - Increase time back and number of traces to fetch in each sampling interval to deal with Jaeger REST interface returning trace data out of order under load (tested to 300 conn/sec; 12K connections currently) - Move trace insert into batch mode to cassandra - Read visibility services to analyze from redis rather than defaults (cloverctl, UI or clover-controller REST will set) - Remove local directory copies in docker build, as image is based on base clover container Change-Id: Ibae98ef5057e52a6eeddd9ebbcfaeb644caec36c Signed-off-by: earrage <eddie.arrage@huawei.com>
2018-06-12	Initial commit for Clover Collector	Eddie Arrage	18	-0/+1194
	- Added a container named clover-collector using clover container as a base with build script - GRPC server to manage collector process - Cassandra DB client interface to initialize visibility keyspace - Init messaging adds table schemas for tracing - traces & spans - Adds table for monitoring - metrics - Does not implement Cassandra server but developed using public Cassandra docker container - Collector process in simple loop that periodically fetches traces and monitoring data and inserts to Cassandra - not optimized for batch retrieval yet for monitoring - CLI interface added to collector process and used by GRPC server for configuration - Simple GRPC client script to test GRPC server and start/stop of collector process - Collector process can be configured with access for tracing, monitoring and Cassandra - Added a return value in monitoring query method - Added ability to truncate tracing, metrics and spans tables in cql - Added cql prepared statements and batch insert for metrics and spans - Align cql connection to cql deployment within k8s - Fix issue with cql host list using ast and collect process args with background argument - Added redis interface to accept service/metric list externally for monitoring (will work in conjunction with clover-controller) - Use k8s DNS names and default ports for monitoring, tracing and cassandra - Added yaml manifest renderer/template for collector Change-Id: I3e4353e28844c4ce9c185ff4638012b66c7fff67 Signed-off-by: Eddie Arrage <eddie.arrage@huawei.com>
