I’m not aware of any single command to do it, but there are a few options. I’ll list a few as they’re all imperfect.
There are some command-line JMX reader commands you could use to extract the information from Ignite’s metrics. You could extract the information from the REST API. I needed to use the jq command to parse it into just a count: http 'http://localhost:8080/ignite?cmd=top' | jq '[ .response[] ] | length' You could search the logs for “Topology snapshot” lines. There’s also ignitevisorcmd that you can script. Regards, Stephen > On 1 Feb 2023, at 09:32, Surinder Mehra <redni...@gmail.com> wrote: > > Thanks, I am aware of it. But I needed this in a script.
