I don't understand this part. You finding a replacement would we the interesting part?
I meant, that removing TSDR dependency from System Metrics app and develop something different may be interesting topic for an intern. dano From: Lorand Jakab -X (lojakab - AAP3 INC at Cisco) Sent: 13. decembra 2016 22:07 To: Daniel Malachovsky -X (dmalacho - PANTHEON TECHNOLOGIES at Cisco); Luis Gomez; Alexis de Talhouët Cc: integration-...@lists.opendaylight.org; controller-dev; systemmetrics-...@lists.opendaylight.org Subject: Re: [Systemmetrics-dev] [integration-dev] Looking for a co-mentor for internship project Hi Dano, Thanks for the info.

Lot of what you wrote is done now – reading cluster members, shards, some shard metrics etc. Yes, after I saw the screenshots from the project proposal, that was pretty much what I was looking for. This looks interesting: “In addition to exposing cluster information, the app would also allow activating a failover from an active cluster in one location to a backup cluster in another location, by manipulating voting states of shards.” This was suggested by Tom Pantelis at the last ODL summit, the idea is to have a 3-node cluster in one location as the active cluster, and another 3-node cluster in a different datacenter for backup. Since inter-datacenter latency can be high, the backup nodes should be non-voting, so they can't become leaders and they don't hold up transactions. Maybe this could be integrated somewhere in the UI. Also, we are using TSDR for “harvesting” controller and machine metrics from JVM Console (I think) in the backend part and we are planning to remove it. Maybe this can be interesting too… I don't understand this part. You finding a replacement would we the interesting part? -Lori dano From: systemmetrics-dev-boun...@lists.opendaylight.org<mailto:systemmetrics-dev-boun...@lists.opendaylight.org> [mailto:systemmetrics-dev-boun...@lists.opendaylight.org] On Behalf Of Luis Gomez Sent: 13. decembra 2016 19:32 To: Alexis de Talhouët Cc: integration-...@lists.opendaylight.org<mailto:integration-...@lists.opendaylight.org>; controller-dev; Lorand Jakab -X (lojakab - AAP3 INC at Cisco); systemmetrics-...@lists.opendaylight.org<mailto:systemmetrics-...@lists.opendaylight.org> Subject: Re: [Systemmetrics-dev] [integration-dev] Looking for a co-mentor for internship project +1, this project if still alive could leverage the intern work.

There seems to be some overlap with my project proposal, I will take the repo for a spin, see what's supported for now. Actually, while the repository was created, initial code was not submitted yet. Correct, still no code there: https://git.opendaylight.org/gerrit/#/q/project:systemmetrics I beleive you could sync up with the system metrics team to better assess their scope, and what the internship proposal could add to that. -Lori -Lori On 12/13/16 3:51 PM, Alexis de Talhouët wrote: Acutally, I might have introduced a confusion. The repo and the project are called System Metrics, not Cluster Metrics as proposed in a first place. This is the current repository: https://github.com/opendaylight/systemmetrics That project was accepted the 2016-11-10 as an incubation project by TSC. + systemmetrics-dev mailing list (although I'm not sure a lot of people are already on it).

I believe the scope of the proposed internship could be coupled with the functionalities that project is going to provide to build a more cohersive "Dashboard" of the cluster along with some cool functionalities for the shards.

We will execute on them, but get the best possible results, I would really like to get a volunteer who is more involved with and more knowledgeable about clustering than I am, to co-mentor this project with me. You can read more about the project at the link [0], but the gist of it is to expose as much information about a cluster as possible in a DLUX app, and allow active/backup fail-over from one cluster to another one, at the geographically remote location (which implies that shards on the backup cluster are initially in non-voting mode, and then a switch is flipped for the fail-over). Any takers?
