Chaitanya,





Sorry for my late response. 






For the errors on the RESTful calls, I think it's most probably caused by some 
kind of resource leak, say unreleased connetions. I'm gonna look into it and 
try to eliminate the problem.






In R2, the DB is used for status maintanence when it comes to the senario of 
scaling of the app. That means no correlation data is stored into or updated 
from the DB.






As the main purpose of Holmes is to identify the root cause when it is used in 
a control loop, the correlation is not published to anywhere. So for now, you 
are not able to get the correlation of the alarms. In R3, one of our streched 
goals is to display the correlation in somewhere. If you are interested in 
that, you are welcome to become one of our best contributors.







Thanks,


Guangrong

Hi Guangrong,


 


Thank you very much for your help on this.


 


I am able to post the rule to the drools engine now successfully using 
camel-case format. Also, I am able to get the CL output on the output queue.


 


However, I am still unable to see any updated correlation on the alarms in the 
DB. I don’t see the rootflag set on the root alarm in the DB. How can I get the 
 updated and correlated alarms as output?


 


Also, PFA some logs which have the error “Failed to call the rule verification 
RESTful API”.


 


Below is the rule I am using:


 


package org.onap.holmes.droolsRuleTest1;


import org.onap.holmes.common.dmaap.DmaapService;import 
org.onap.holmes.common.api.stat.VesAlarm;


                                import

                                rule "Test_Rule_100"


                                salience 200

                                $sourceId: sourceId, sourceId != null &&

           startEpochMicrosec < $startEpochMicrosec + 60000 && 
startEpochMicrosec > $startEpochMicrosec - 60000 )   


                                   


                                   then


                                  


                                   DmaapService dmaapService = 
ServiceLocatorHolder.getLocator().getService(DmaapService.class);


                                    PolicyMsg policyMsg = 
dmaapService.getPolicyMsg($root,$child,"org.onap.holmes.droolsRuleTest1");


                                   $root.setRootFlag(1);


                                   update($root);


                                   System.out.println( "In the then" );


                                   dmaapService.publishPolicyMsg(policyMsg, 
"unauthenticated.DCAE_CL_OUTPUT");


                                  


                                   end

Chaitanya,

 

Sorry that I failed to locate any "Failed to call the rule verification RESTful 
API" related error in the log files. There's only one record regarding the rule 
deployment operation and the result  is "success".

 

I suggest you to retry it with the check point I sent to you in the previous 
email first and if there's still errors, send me the latest logs, please.

 

Let me know if there's still problems or questions.

 

Regards,

Guangrong

Hi Guangrong,


 


Thank you very much for your response. Please find attached the logs from both 
the rule-mgmt and engine-mgmt  dockers.


 


1.      Please note that I only notices the “Failed to call the rule 
verification RESTful API” error with the new Beijing release of Holmes. With 
earlier Amsterdam   I never faced this issue. 


2.      PFA some screen shots of alarms and rule in Postgres DB. Also below is 
the exact rule (simplified version from the wiki page) and the rules I am 
trying.  I  have simplified them in order to see some straight forward result 
removing dependency on AAI and DMaaP.  I have tried with the actual rule and 
and alarms available in the wiki page 
https://wiki.onap.org/pages/viewpage.action?pageId=16002659  but dint get any 
result  either/

Hi Chaitanya,

 

To address the problems you mentioned below, I need more information:

 


1.      For the "Failed to call the rule verification RESTful API" error, the 
message you provided is too anbiguous. It's better you send the complete error 
stack or go to /var/log/ONAP/holmes/zip   of the rule management docker, 
collect all the log files under that and send them back to me.


2.      The rules and alarms are always supposed to be stored in the DB unless 
an explicit command is executed to remove the rule(s) or any abating alarms are 
received from  DMaaP.  I don't know how to reproduce such kind of errors. Could 
you please give me more details, such as the steps to reproduce them.


3.      In order to generate correlation among alarms, you have to modify the 
rule or the alarms to make them match each other. Further more, you have to 
ensure that the rules  are  deployed into the Drools engine successfully.


4.      As for other errors you high lighted below, they are false positives. 
The cause of the problems is that DCAE is not deployed. Since you're not using 
HOLMES as a DCAE  application,  you don't have to care about them. This will be 
optimized in R3.

Best Regards,

Guangrong

主 题 :ONAP HOLMES issue




Hello Guangrong,


 


How are you doing? Hope this email finds you well.


 


I am hoping that you could help me resolve an issue I have been facing with 
HOLMES. I have tries both Amsterdam and Beijing versions and I am facing the 
same issue with both. I   suspect I may be doing something wrong.


 


I am trying to run HOLMES In stand alone mode following the steps detailed in 
the https://wiki.onap.org/pages/viewpage.action?pageId=16002659  page. I ran 
this with Beijing release of HOLMES in the hope that it would have fixed the 
issue i was facing earlier. But unfortunately  i still face the same issue as 
before. Below is the error  i get. 


With Beijing release i am also facing the issue of posting the rule to 
rule-engine. Some times it throws "Failed to call the rule verification RESTful 
API"    error. If i rebuild the dockers then it will work again. 


Also, the rules and alarms seem to disappear from the Postgres DB after a 
while. I am not sure if this is designed this way or if its an error. 


 


Are the rules supposed to be posted to engine-mgmt docker as well? I dont see 
any thing happenning once the alarms are posted to DMaaP. i could see the 
alarms reaching the engine-mgmt    and getting saved to DB from the debug log. 
But no correlation happening after that. 


 


Can you please provide any help?
