Notify Federation when unexpected Federate crash #162

Closed icemagno closed 8 years ago

icemagno commented 8 years ago

HI, I don't know if I made some mistake. I need to be notified ( in an Ambassador event ) when a Federate crashes.

My test:

One federate running and using a NullFederateAmbassador extended class with all methods( with some out.println just to debug)

The RID file is ON ( TRACE log level )

Other Federate (different class) running and updating some attributes every 5 seconds.

I can see the logger output in the first Federate every time attribute changes in the second Federate.

Now, I just stop the second Federate execution by closing the program (without letting the Federate do resign stuff ) to simulate a machine crash or something like..

The first Federate logger simply stop update without telling me what was happened with the second guy.

am I doing something wrong or is this the correct behaviour ?

timpokorny commented 8 years ago

G'day mate,

What method are you expecting a callback on?

The MOM can typically handle this. A Manager.Federate object is created for each federate and if a federate goes away (gracefully or otherwise) that object is deleted.

Unfortunately the MOM for that section is only properly implemented for HLA 1.3 at the moment. Not in 1516e :(

There was a reason for this being non-trivial. I can have a look at weekend about how to bring it in or another way to support the use case.

icemagno commented 8 years ago

I think I get your point. After some ressearch I found this document:

http://aegistg.com/Technical_Papers/HLA%20to%20the%20WebSept00.pdf

Page 4:

fed_manager

A more (older) detailed one:

http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.39.1509&rep=rep1&type=pdf

A look into HLAStandardMIM.xml and I found HLAmanager.HLAfederate instead Manager.Federate.

INFO [localhost-startStop-1] portico.lrc: MOM support is currently unsupported in IEEE-1516e federations.

:-(

Thanks!

timpokorny commented 8 years ago

Yes - there was some reason this got pushed off. I'll take a sit down on the w/e and have a look to see if it can get in quickly for this base stuff and report back. Cheers, Tim

icemagno commented 8 years ago

Fantastic! You're always giving the best support ! But take it easy. Don't spend your w/e solving problems. Go surf! Many thanks pal.

timpokorny commented 8 years ago

G'day mate, still working through this but making some progress (haven't forgotten you).

icemagno commented 8 years ago

No problem pal. At your time.

timpokorny commented 8 years ago

G'day mate - STILL hacking away at this. I recall all the grand reasons why this wasn't simple now. It is a rabbit hole. Most of the work tracking over on ticket 55 (link above) if you want to see.

icemagno commented 8 years ago

Be cool. I have time. I'll focus in other problems ( regions and DDM ) until you solve this. I appreciate your efforts and concern to keep me updated.

icemagno commented 8 years ago

Hi Tim, I want to invite you to send criticism, suggestions and opinions to my new blog about HLA ( more precisely about Portico RTI ). Will be a honor if you want to correct me ( i'm not a HLA guru ), my english ( not very good ) and a bigger honor if you want to be a poster there. My text is snippet-like step-by-step tutorials because was hard to me to find simple tutorials on the web. I know you're giga-busy and will understand you don't to.

Thanks.

@icemagno - reference #55 for details. Good to go I hope :S

I see all normal. Federate 01 log is telling me Federate 02 is in the game.

Now, let's simulate the Federate 02 ( Teapot Node ) crash by simply closing your running terminal. A big bada-boom!

Terminal closed. I don't give time to Federate 02 to resign or even know what happen.

At this time, I expected to see some log in Federate 01 telling me the epic dead of Federate 02.. but not even a line of log was printed.... none. Federate 01 ( and the RTI ) still thinking Federate 02 is still alive. I can proof this by trying to start Federate 02 again... a name conflict error raises on Federate 02 screen.

I see a kind of trouble because the Federate don't have a place to still connected ( like a Central RTI Component ). AFAIK I will need to pool every Federate ( maybe an Interaction ) to discover who is still alive, but it may inject some noise into the network.

Poo. Let me look into it. It might take a little bit to show up as JGroups has to detect that it has gone down, then confirm, and then notify. Let me dig in. Cheers, Tim

Well, here is :

This is the Federate 01 start log ( Sagitarii ) in a Federation called Sagitarii ( too ): The FOM is the Standard MIM and the SOM is the same in both Federates.

I see all normal. Federate 01 log is telling me Federate 02 is in the game.

Now, let's simulate the Federate 02 ( Teapot Node ) crash by simply closing your running terminal. A big bada-boom!

Terminal closed. I don't give time to Federate 02 to resign or even know what happen.

At this time, I expected to see some log in Federate 01 telling me the epic dead of Federate 02.. but not even a line of log was printed.... none. Federate 01 ( and the RTI ) still thinking Federate 02 is still alive. I can proof this by trying to start Federate 02 again... a name conflict error raises on Federate 02 screen.

kataner83 commented 8 years ago

Hi everyone, i would like to mention that besides the mentioned things here i believe that "crashed federates are not properly resigned from the federation they are running in.

Greetings Volker

icemagno commented 8 years ago

Yeap! I think this is an important feature/behaviour to keep the federation integrity. The existence of a federate cannot be left in doubt.

timpokorny commented 8 years ago

Completely agree - what should happen at the moment is that there should be a detection that the federate is no longer present (we use a couple of things under the hood for this). Then a resign should be synthesized for all federates. I believe the failure detection is currently getting screwed up. Looking into it now.

timpokorny commented 8 years ago

Looking at this over the weekend. I can see the messages that JGroups passes when a federate is suspected of crashing coming through, but for some reason the Group Management Services don't seem to be acting on that to remove the federate, which would then trigger the pseudo resign notification. Looking further.

timpokorny commented 8 years ago

Have identified a fix. Bug is due to changes in group management as a result of adding WAN support. Getting ready to push the fix but a couple of tests have broken so investigating those first.

timpokorny commented 8 years ago

Other problem identified and fixed. Patches pushed to master. Checking main build now.

timpokorny commented 8 years ago

master build passing. Will get @icemagno to confirm, but this should be fixed now.

icemagno commented 8 years ago

Thanks. I'll try it ASAP.

icemagno commented 8 years ago

Perfect! Its working fine. but ... Can it be faster? I need to wait near 5 seconds to be "rude" and 5 seconds more to the resign message be fired in the ambassador.

timpokorny commented 8 years ago

I'll have a looksie, but it's all a balance. It needs some time to determine whether the absence of the federate is actually a failure or whether it is just a delay (perhaps delayed send due to cpu exhaustion, retrans required due to network loss, etc...). Currently very conservative.
