- Added a 'common' directory where all shared code has been placed
- Analytics package has been moved out of dcdbpusher, now has its own makefile
- Some renaming here and there for uniformity

Msr

See merge request dcdb/dcdbpusher!2

- Fixed a minor issue that caused text corruption when using the -h
option on certain shells
- Collectagent now exits gracefully also when receiving a SIGTERM signal

- Using the "delay" parameter, analyzers can be started in a delayed way
- Useful to let sensor caches fill and prevent errors being thrown

- Setting a maxMsgNum of -1 will result in the minimum possible value
(slightly above the predicted message rate) being picked as a cap
- Added some logging to make the feature more verbose

- Added configuration options to tune the Cassandra driver for
optimal performance
- Added a "debugLog" configuration switch that enables logging of
errors in asynchronous inserts in the Cassandra driver

Changes to handle conflict with monitoring: 1. we check if counters are already running, and just read them if this is the case. 2. we program them if they are not running. 3. When dcdb stops, they are left running for other agents like EAR.

- The CollectAgent sensor cache is automatically purged each X seconds
(X is configurable through the cleaningInterval parameter), deleting
all entries than have not been updated in the last X seconds
- Fixed some minor bugs related to index management in sensor caches

-check if counters already enabled before programming them
-reset counters if stopped

- Cache interval was previously not correctly set

- Fixes to minor bugs that kept the plugin from compiling

- Implemented a check in MQTTPusher that prevents the main publish
loop from being invoked anytime mosquitto_loop returns, but only once
every second at most

- Values for MaxInflightMsgNum and MaxQueuedMsgNum are now logged at
startup

- Checking for invalid sensor names in SensorNavigator auto build mode
- More meaningful logging when failing to build sensor trees

- If no sensor hierarchy is specified, SensorNavigator will build a
tree by interpreting each sensor name as a dot-separated path
- Minor changes to README

- MaxMsgNum configuration parameter now defaults to 0 (no message cap)
- The sensor hierarchy string is now logged at startup
- A rebuild of the SensorNavigator is now triggered only at plugin
reloads over the REST API

Make use of mosquitto_max_inflight_messages_set() and the new mosquitto_max_queued_messages_set() functions to limit the amount of memory spent in mosquitto for queued messages.
Rework the handling of disconnects/reconnects

Add mosquitto_max_queued_messages_set() function to mosquitto to limit the number of messages that may be queued.
