Recent UI enhancements & Managed Service Providers

Hi All, I am running older versions of Mesos & Marathon (0.23.0 and 0.10.0). Over the course of the last several months I think I've seen several items on this list about UI enhancements. Perhaps they were enhancements to the data consumed by the Mesos & Marathon UIs. I've had very little time

Re: "Chaos monkey" for mesos?

The DCOS tutorial mentions a chaos tool at the end of the video. Not sure if that's what your looking for, but it might be something to follow up on somehow. https://mesosphere.com/learn/ David Wood Computing Systems for Wireless Networks IBM TJ Watson Research Center daw...@us.ibm.com

Re: Recent UI enhancements & Managed Service Providers

Hi Vinod, Thank you for your reply. I'm not sure that I can be more specific. MSPs are interested in a "view by tenant", e.g., "show me all applications that are allotted to Tenant X". I suppose that the standard Mesos UI could, with properly named task IDs and the UI's "Find" filter,

"Chaos monkey" for mesos?

Has there been any work done to develop a "chaos monkey " analogue for Mesos? I have been researching on how to write one, but I wanted to know if there's any work already available that I can take a look at for comparison, and possibly

Mesos metrics -> influxdb

Has anyone had a good experience recording mesos metrics into influxdb? I've found a couple of options, a collectd plugin which doesn't appear to work with version 0.24.x and a more up to date containerised option which randomly crashes regularly and doesn't appear to actually post any stats.

Re: Mesos metrics -> influxdb

Not Mesos metrics, but we've been using InfluxDB in this demo here: https://github.com/mesosphere/time-series-demo Given the volume to be expected, I'd prolly be looking into something more scalable like KairosDB, see for example https://github.com/mesosphere/cassandra-kairosdb-tutorial HTH!

Re: "Chaos monkey" for mesos?

Thanks. Craig and David. I'm curious about the design and use of that tool. Based on the video, it looks close to what I hope to do. A web search didn't yield any results about it, however. Does anyone here know more about the dcos chaos tool? Thanks again. Srikanth On Thu, Feb 25, 2016 at

Re: "Chaos monkey" for mesos?

I think you could approximate that tool's behavior with some scripting plus `mesos-execute` (ships with the distribution) or by writing a really simple framework that just turns things off. On Thu, Feb 25, 2016 at 1:14 PM, Srikanth Viswanathan wrote: > Thanks. Craig and

Re: "Chaos monkey" for mesos?

Appreciate all the responses here. I'll look into `mesos-execute`. I was thinking about the framework idea in passing but my mesos knowledge isn't up to scratch yet, so I haven't been able pursue it yet. There are many questions in my mind w.r.t designing this as a framework: * Doesn't a

Hello Jie, Thank you for the quick reply. Sorry for asking silly question. How can i look for the taskinfo of a running container ? Can i see the TaskInfo details in the mesos master UI for a task? On Thu, Feb 25, 2016 at 10:52 PM, Jie Yu wrote: > You can take a look at

Sorry, ignore my first question. A framework can obviously kill tasks. I was just unsure as to whether it can kill foreign tasks, which leaves only my second question. On Thu, Feb 25, 2016 at 5:23 PM, Srikanth Viswanathan wrote: > Appreciate all the responses here. I'll

Hello, >From docker containerizer documentation ( http://mesos.apache.org/documentation/latest/docker-containerizer/), *"Users can either launch a Docker image as a Task, or as an Executor."* How can i identify whether a docker container started by lets say marathon is running as a task or as

Feel free to create one. I don't have enough information to know what the issue is without doing some further investigation, but if the situation you described is accurate it seems like a there are two strange bugs: -the silent exit (do you not have the exit status?), and -the flapping from ZK

Re: Question regarding docker containerizer

You can take a look at the TaskInfo. If the TaskInfo does not have ExecutorInfo set, then it's a task. Otherwise, Mesos will launch the executor and send the task to the executor. - Jie On Thu, Feb 25, 2016 at 2:50 PM, Pradeep Chhetri < pradeep.chhetr...@gmail.com> wrote: > Hello, > > From

Re: Question regarding docker containerizer

Yeah, that's the command task. Mesos run all tasks using some executor. If the user does not specify one (command task case), we will use the default mesos executor. On Thu, Feb 25, 2016 at 4:10 PM, Pradeep Chhetri < pradeep.chhetr...@gmail.com> wrote: > Hi Jie, > > I see executor_id as empty.

Re: Question regarding docker containerizer

Hi Jie, I see executor_id as empty. Does this means that it is running as task and there is no executor for it ? Although, in the ps output, I see mesos-slave is spawning a mesos-docker-executor which in turn spawning the docker command. Here is the detail of one of the marathon task: {"id":

Re: "Chaos monkey" for mesos?

There's no way to kill a single task through the Mesos control surfaces, but if you let the "chaos" framework launch tasks as a privileged user, you can run wild. On Thu, Feb 25, 2016 at 2:49 PM, Srikanth Viswanathan wrote: > Sorry, ignore my first question. A framework can
