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,
Guangrong

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.
Regards,
Yuan

Hi
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.

Junjie,
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?
Thanks,
Lusheng

Hi
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.

Liu,
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.
thanks

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.
Thanks,

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
cloud.
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.
