Hi LiuYuan,

Sorry for having made you confused. For data filtering, I think DMaaP performs 
this on the data stream level and Holmes do this on the business related level. 
This is the main difference between these two porjects. Besides, how to filter 
data (more specifically, alarms) depends on the definition of the specfic 
rules, which means Holmes can handle the data more flexibly.

I updated the wiki page (https://wiki.onap.org/display/DW/Holmes) just now, pls 
have a look at it.

Feel free to contact me if you have any questions.

Best Regards,

Hi Junjie,

I just quickly review the Holmes proposal and DMaaP proposal. I have some 
confusions, please help me to clarify. Thanks.

For the scope part, does the filtering function will be implemented in DMaaP 
project? Or What is the difference between Holmes filtering and data filtering 
in DMaaP? I guess there are some overlap.

In addition, the compression and aggregation function of Holmes is quite 
different with the function in DMaaP. Holmes is in the service level, and DMaaP 
is in the data level. Do I understand correctly? Because you use the same 
words, it is a little confusion for me.

    As my understanding,  the rules in Holmes just only define how to correlate 
the enents, the policy consist of three parts, the events for triger policy, 
the rules of policy and the action of policy. So i think Holmes is belong to 
DCAE which mostly related to analysis. 

    For align project, we think now DCAE in ONAP provide the framework, Holmes 
project  can be a sub-project as one DCAE special application project, we image 
there will be more and more DCAE application projects in more areas in DCAE. 
considering easy to manage DCAE project  in the future , we wish DCAE project 
as framework and the 'Holmes' as a application project. Project risk division 
can be good for first release.

I still have not received any feedback from ZTE regarding the deep dive of the 
Holmes project.  We need to decide how to align projects.

 Mazin and Junjie,


As I was preparing the DCAE project proposal,  I had the same impression as 
Mazin that Holmes correlation engine appeared to align well with DCAE's micro 
service analytics architecture.  Hence I put in a placeholder for possible 
harmonization   with Holmes.


However this afternoon I had some time to briefly scan through Holmes Mercury 
source code and now I am actually feeling less confident about this impression. 


Holmes implementation appears to consist of code around two major functional 
components, a DB (mysql) and a rule engine (Drools).  The rules are stored in 
DB, and loaded into Drools engine.  The Drools engine monitors Active MQ topics 
for  alarms, then matches alarms with some rules.  Is this high level 
understanding correct?  


If so, this actually appears to resemble some of the Policy Engine 
implementations more than DCAE analytics (cc-ing Pam, who is Policy Engine 
lead).  I think we need to schedule a deep dive meeting finding how to best 
align.  Given now  it is already Friday afternoon in China, shall we target 
early next week?

   Yes, I agree with your suggestion, Holmes will be  a Microservice 
application running in DCAE just like all analytics Microservices. Holmes is 
not a independence application without DCAE structure.

Interesting. I need to spend time looking at Holmes a bit closer.


From a first glance, the rule designer seems like a GUI for writing policies.

The correlation engine is an algorithm that ingest data and provides signatures 

based on those correlations. If my interpretation is right, then I suggest 

putting the correlation engine as a Microservice running in DCAE just 

like all analytics Microservices.


The GUI is similar to CLAMP. CLAMP allows you to design open and closed

loop systems besides just putting the policies and rules. CLAMP connects

with ONAP during both design and runtime.


Something to think about.

The dcae proposal includes holmes as a sub part (·  Holmes: this is an OpenO 
project that performs similar/related  role to  DCAE.  Further information is 
needed for identifying path for normalization.)


Did you talk to anyone from dcae about overlap? If so what was the differences 
between your projects? Just trying to wrap my head around the difference for my 
own edification.

Dear all

           Holmes project provides alarm correlation and analysis for Telecom 
cloud infrastructure and services, including host, vim, vnf and ns.  Homels 
aims to find the reason which cause the fail or degradation  of services by 
digging into the ocean of events collected from different levels of Telecom 

           Holmes is a application that processes events published by managed 
resources or other applications that detect specific conditions. Based on 
defined root cause analysis rules about the network,   an application of this 
kind would determine root cause for various conditions and notify other 
interested applications.



Holmes is consist of a rule designer and a correlation engine.Rule Designer 
provides a user-friendly GUI to design the Correlation rules.

Correlation Engine receives original alarms from monitor and output the result 
back to monitor after analysis based on rules and the resources relationships 
from AAI.

Real-time Analytic application get the analysis result, which is the root cause 
can be used to drive the policy runtime for automation operation.
