Samarth,

Gunnar, our Chief Technologist on DSM can answer all your questions but briefly:
1.  The Phoenix log table can be a source for the central repository but the 
central repository is in Vertica (you can use the community edition).  This 
could be any database and we are working on making Trafodion the repository 
soon. It requires making all the DDL and DML work with this new Central 
Management Instance (CMI) repository.
2.  Various means can be used to access the Data Service Instance (Phoenix) 
data to map to the normalized schema of the CMI. When Gunnar presents it to you 
he can cover these mechanisms.
3.  The UI dashboards and whiteboard provide these capabilities against the 
CMI.  Vertica's analytical support helps with that. Trafodion has most of that 
support but would require changing some queues and pulling some of it into the 
client.
4.  We would like to open source it but have not made that decision as yet.  
There are potential open source models short of open sourcing all of it.  But 
the pricing model for it in the interim is an open source pricing model.

Hi Rohit,

I am interested in knowing more about DSM and its capabilities. I have some 
questions:

1) Phoenix logs the traces in a Phoenix table. Can a Phoenix table work as a 
DSM repository?
2) Does DSM expect data to be in a particular format or does it provide a means 
to plug in you own data puller (JDBC, REST etc)?
3) Does it provide an analytical engine that can roll up data (among other 
operations) and slice and dice it on various dimensions?
4) Is it open sourced? From the email it sounded like it isn't.

Thanks,
Samarth

JMX interfaces are fine, too.

Thank you,

Thanks Nick!  Yes Data Services Manager (DSM) does provide the kind of 
perspective Pari is looking for but not for Phoenix.  Actually, if Phoenix is 
providing metrics and information in a repository or via a REST interface, on 
queries, elapsed times, etc. then certainly it could be incorporated into DSM.  
Trafodion is doing that now in R1.0 and we are working on having DSM provide 
full support for Trafodion along with complete support for HBase (some of it 
being already there), in order to provide a comprehensive view of all workloads 
from HDFS, HBase, to SQL.  We did have plans to provide a SDK so that data 
services like Phoenix could be easily plugged into DSM.  Not a hard task – just 
time and effort ☺.

If Pari is interested, we can certainly demo the tool and go from there based 
on interest.

Rohit

Hi Pari,

I'm not aware of a Phoenix-aware, end-to-end solution here. You can probably 
write a custom collector for a Phenox application that can report into 
OpenTSDB; I think JDBC metrics are available via JMX. That would be a great 
addition for that project!

I've also seen a product demo from HP that does a lot of this for other tools 
on HBase, though I don't think it supports Phoenix yet (cc Rohit).

Thanks,
Nick

Hello All,

Can you suggest good monitoring tool for phoenix. Our QA hbase cluster is
crashing randomly. We wanted to know stats like which query causing the
issue and how many queries running on that particular time window, resource
consumption of query etc.

Cheers
Pari
