Can I run mesos/marathon application at specific host?

Question

I wanna use marathon as cluster monitoring and management. Bellow scenario is possible?

My Scenario

• Cassandra 5EA was already deployed and are running.
• Cassandra hosts are physical machine.
• I want to run script that verifies healthness of cassandra each host. ex) cassandra process, disk usage, number of file, ..
• If problem found at host, than run correcting script on that host. Script launched manually.

Each script can be run by marathon application. But I couldn't found run application on (specific) error host. No restriction of adding machines and installing mesos components.

And if you know more suitable tool, please recommend!!

Answer 1

If you are not running Cassandra on Mesos I think Marathon is not the best choice. From your description, it looks like you need a monitoring tool (e.g., Nagios) rather than service Orchestration.

Please extend your question with more information. It's not clear what you are asking.
