Hi Guangrong,
1. In the current CLAMP design the settings of the configuration of Micro-service (so in this case Holmes rules) are made in CLAMP and send as policies to Policy. Policy then distributes them to the micro-service. Those are called in CLAMP configuration policies. In my previous emails I was talking about policies for policy itself (called in CLAMP operational policies) so not the configuration/rulings of micro-services which is different. Anyway, this is still under discussion! And at this point is just talk, so nothing has been implemented or finalized yet in that direction for operational policies (Policy specific rules) used by Policy itself!!. 2. Yes, CLAMP talks to DCAE to trigger the deployment of DCAE micro-services.

According your previous email, policy rules are designed in CLAMP and distributed by SDC. Then which system will be responsible for designing and distributing Holmes rules? CLAMP or SDC? 2. What's the workflow to deploy analytic apps/collectors to DCAE? Will CLAMP portal talk with DCAE to deploy them? Thanks in advnace.

Concerning the Policy, the direction of the design is to have SDC directly distributing policy rules to Policy (instead of CLAMP), but this is still under design.

My understanding is that since the template in CLAMP is exactly the same as the blueprint in DCAE, if Holmes could translate the template given by CLAMP, there will be no problem for it to interpret the blueprint provided by DCAE. Therefore, what matters now is that I need to have a clear idea on how the template is mapped into the rule so that I could have a better understanding on how the whole stuff works. That's the reason I asked for a sample from both CLAMP and Policy. In a nutshell, I need to know how the rule is defined in the template and then converted into the format which could be consumed by the drools engine. I hope I've made myself clear.

So what we refer to as CLAMP template is really DCAE template that CLAMP customize and send to SDC. SDC then distribute this template to DCAE Orchestrator.

To create such a rule, some information for alarm identification, such as alarm code or alarm name, resource (where the alarm is raised) information, etc. must be provided in advance. ===================== rule starts here ===================== package gsm.bsc.test import xxx.xxx.xxx; rule "NFVO_SameHost_Relation_Rule" salience 120 no-loop true when $root : Alarm( eventType == Alarm.EVENT_RAISED, probableCause == "RAM error", $hostname:hostname, hostname != null && !hostname.equals(""), $vmname:vmname, vmname == null || vmname.equals(""), $aid: aid) $child : Alarm( eventType == Alarm.EVENT_RAISED, aid != $aid, hostname == $hostname, probableCause in ( "compute is not available","VNF IP NSVC unavailable" ), this after [-60s, 60s] $root) then AplusServiceAccess.getAplusOutputService().publishRootChildResult("rule1", $root, $child); end rule "NFVO_Notify_Policy_Rule" salience 120 no-loop true when $alarm : Alarm( eventType == Alarm.EVENT_RAISED, probableCause == "RAM error", $hostname:hostname, hostname != null && !hostname.equals(""), $vmname:vmname, vmname == null || vmname.equals(""), $aid: aid) then Event event = new Event($alarm); AplusServiceAccess.getAplusOutputService().sendEvent("rule2", event); end ===================== rule ends here ===================== The question from Holmes’ side is how CLAMP template is translated into this kind of rule? It’ll be great if you could give us a sample of a CLAMP template and the corresponding Policy rule. I’m not sure whether the info above would be useful or not for you. If further information about Holmes and the rules is needed. Please feel free to contact me. BR, Guangrong
