Alexey, Have a look at the 'PluginProvider' interface, if you implemented a telemetry service as a plugin: * plugin may be placed in the 'web-console' module; * plugin is initialized at node startup and is stopped at node shutdown; * plugin have access to all Ignite's internals through context; * listening of discovery topologies events allows you implementing some kind of cluster singleton, to be able to deploy telemetry-service in case previous one failed.
