Hi Ramindu,
thanks for this.
Effectively I saw that everything has been changed in new analytics
distribution, and I can't cope with it ;-(
By default I don't see any users stuffs, like the use user-mgt.xml file. So I
suppose the "admin" user is just store in the DB, nothing else.
I didn't change the default password for it, but remote ESB instances are
unable to send data to analytics because of
ERROR
{org.wso2.carbon.databridge.core.internal.authentication.CarbonAuthenticationHandler}
- Authentication failed for username 'admin'. Error : 'Invalid_Credentials'.
Error Description : 'The login credential used for login are invalid, username
: 'admin'.'
ERROR {org.wso2.carbon.databridge.core.internal.authentication.Authenticator} -
wrong userName or password
Local instance (I mean IE640 running on same localhost) can.
I just edited this files to put admin/admin as user/passwd
<EI_HOME>/repository/deployment/server/eventpublishers/MessageFlowConfigurationPublisher.xml
& MessageFlowStatisticsPublisher.xml
Thanks for your help,
Bernard

Hi Bernard,
EI analytics 6.3.0 uses WSO2 DAS<https://docs.wso2.com/display/DAS320> runtime.
EI analytics 6.4.0 uses WSO2 SP<https://docs.wso2.com/display/SP430> runtime.
WSO2 SP is a total rewrite of the WSO2 DAS, which has a feature enhancements as
well.

Hi devs,
we were using these only 4 DBs to make analytics aggregating datas from our ESB
until version 6.3.0 ;
ANALYTICS_CARBON_DB
ANALYTICS_METRICS_DB
ANALYTICS_EVENT_STORE_DB
ANALYTICS_PROCESSED_DATA_STORE_DB
We have our from the scratch data aggregation
mechanism<https://wso2.github.io/siddhi/documentation/siddhi-4.0/#aggregate-function>
instead of using apache spark which was in DAS. And that the the explanation
for not having configurations for ANALYTICS_EVENT_STORE_DB and
ANALYTICS_PROCESSED_DATA_STORE_DB's .
We still have the ANALYTICS_CARBON_DB and ANALYTICS_METRICS_DB.
Please look into Monitoring Stream
Processor<https://docs.wso2.com/display/SP430/Monitoring+Stream+Processor>
in-order to configure the metrics for WSO2 SP.
These were postgres databases.
Now I see there are more then 10 databases preconfigured in the default
analytics 6.4.0 config (conf/dashboard/deployment.yaml and
conf/worker/deployment.yaml).
Well, … this is suggesting me lot of questions.
First of all, is it still recommended (like it is for ESB&DSS databases) to do
*not* use local H2 databases in production environment ?
This question comes because the 6.4.0 analytics seems to me to be used as it
is, out of the box, lot of DBs and no documentation for a any configuration as
it was for previous versions.
Yes. We still recommend NOT to use the embedded H2 databases.
If we need to create external DBs for all the stuffs, what exactly are each DB
for ?
Please refer Configuring
Datasources<https://docs.wso2.com/display/SP430/Configuring+Datasources>
Is there any migration tool and/or documentation about migrating from analytics
6.3.0 to 6.4.0 ?
(https://docs.wso2.com/display/EI640/Upgrading+from+WSO2+EI+6.3.0 does't talk
about that)
Any matching between former 4 DBs and the 6.4.0 new ones ?
ANALYTICS_CARBON_DB - In-order to use/ migrate this database the previous
analytics, please answer the following questions
Seems, you are not using a usr-mgt database, Do you have add additional users?
If not its not necessary to migrate the carbon db. You just can move on with a
new db
ANALYTICS_METRICS_DB - Metrics values stored in the DB depends on the node that
we run. But IMO since this is a new version of the product, there is no use of
migrating the older metrics data into the new one.
ANALYTICS_EVENT_STORE_DB and ANALYTICS_PROCESSED_DATA_STORE_DB - This is
replaced by aggregation tables. And
aggregation<https://wso2.github.io/siddhi/documentation/siddhi-4.0/#aggregate-function>
will be done via Siddhi<https://wso2.github.io/siddhi/>
Is there a way to keep (transfer into 6.4.0) datas we collected with previous
analytics version ?
We are currently looking at several methods in-order to migrate the
ANALYTICS_EVENT_STORE_DB and ANALYTICS_PROCESSED_DATA_STORE_DB data and we will
update you on that regard.
Thanks,
Bernard
