Hi, I’m trying to build a tool/library that could detect if CloudStack’s port 8250 is unresponsive, this port is used for unauthenticated mgmt server and systemvm (agents) communication. The protocol used here is not transparent either, it a low level TCP based one which uses custom headers, gzip compression of json serialisation of objects. Is there a documentation I can follow?
The issue is that sometimes, CloudStack API layer (port 8096, 8080) may work and give valid results but the agent communication may overwhelm port 8250. If there is a way to detect this, a loadbalancer can shift loads on port 8250 to some other mgmt server. Apart from StartupCmd and two otherAgentControlCommands (both related to console proxy), there is no way to get information about mgmt server. Is there a way that I missed by which a dummy agent can get version or any other information about the management server? I wrote a dummy agent shell that simply connects to localhost:8250 (the local mgmt server) (would be great if we can document the communication protocol so one could write monitoring tools in something other than Java) DummyAgent; https://github.com/shapeblue/cloudstack/commit/7b5c34a35d3bed756e6458646c916897e3944910 Regards, Rohit Yadav Software Architect, ShapeBlue M. +91 88 262 30892 | rohit.ya...@shapeblue.com Blog: bhaisaab.org | Twitter: @_bhaisaab Find out more about ShapeBlue and our range of CloudStack related services IaaS Cloud Design & Build<http://shapeblue.com/iaas-cloud-design-and-build//> CSForge – rapid IaaS deployment framework<http://shapeblue.com/csforge/> CloudStack Consulting<http://shapeblue.com/cloudstack-consultancy/> CloudStack Infrastructure Support<http://shapeblue.com/cloudstack-infrastructure-support/> CloudStack Bootcamp Training Courses<http://shapeblue.com/cloudstack-training/> This email and any attachments to it may be confidential and are intended solely for the use of the individual to whom it is addressed.
