Hi, first of all, congrats for Marvel release. Step in the right direction. I have some questions: If I understand correctly, as of now Marvel has to run in the cluster that it collects metrics from (as a plugin). Let's call this cluster A. It is recommended for production env to have the Marvel store the metrics to a different cluster. Let's call it B. Now, does it in fact mean that in order to browse collected metrics (that are stored in B) the client has to have an access to at least one node of A? (I assume this is necessary to download the Kibana based web app?). Or let me put it this way: in case of critical state of cluster A client has to know which nodes of A are responsive and able to serve the web app prior to investigating historical data stored in B? If yes, is there any plan to get just the web app as a standalone package (like zip, war ...) so that client does not have to rely on cluster A to serve it? Am I misunderstanding the concept?

Hi Lukas, Not sure I follow. The Marvel plugin has to be installed on all nodes in cluster A and on nodes in cluster B (with the agent disabled). To view the data you would open http://node\_from\_cluster\_B:9200/\_plugin/marvel , so if something goes wrong with A, you still have access to the data. Makes sense?

Ah, so the plugin needs to be installed on both clusters, I missed that part. Thanks for clarification. BTW, is it required to have the plugin on both sides because the plugin on cluster B does more than just serving the web app in this case? Say, I want to monitor cluster A and store data into cluster B - thus I install plugin on cluster A and configure accordingly, but do not install the plugin on B, instead I just keep copy of the web app locally in case I would want to access the data in cluster B? Hope my question makes sense... Regards, Lukas On Thu, Jan 30, 2014 at 11:32 AM, Boaz Leskes [b.leskes@gmail.com](mailto:b.leskes@gmail.com) wrote: > Hi Lukas, > > Not sure I follow.

My understanding is that the jar file that is part of the plugin is only needed on cluster A, while the \_site content is only needed on cluster B. Without the jar file on cluster B, the agent does not need to be disabled since there is no code to disable. Cluster B should be able to continue ingesting content if Marvel is indeed using the standard API. -- Ivan On Thu, Jan 30, 2014 at 4:15 AM, Lukáš Vlček [lukas.vlcek@gmail.com](mailto:lukas.vlcek@gmail.com) wrote: > Ah, so the plugin needs to be installed on both clusters, I missed that > part.
