Get TotalServerNodes using controlscript/Rest Api
Hi,
I am trying to find a way to fetch the count of server nodes in ignite
cluster but don't see any control script option or in Rest api. Could you
please suggest if it is possible. Below link shows this is exposed as a
cluster metric but not accessible through above two options.

Please, don't rely on visor.

You amazed me sir. Thanks a lot, I will update the linked thread on
stackoverflow. Command looks like below now
kubectl --kubeconfig config.conf exec <ignite-node> -n {client_name} --
/opt/ignite/apache-ignite/bin/./control.sh --metric
cluster.TotalServerNodes | grep -v "metric" | grep
cluster.TotalServerNodes | cut -d " " -f5 | sed 's/^ *//g'

Hello.
You can query any metric value or system view content via control script [1], [2]

or [3]

Re: Get TotalServerNodes using controlscript/Rest Api

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.

Stephen

Thanks, I am aware of it. But I needed this in a script. So either curl or
control options would be good.

Hi,
Do you have a chance to use a java client?
https://ignite.apache.org/docs/latest/thin-clients/java-thin-client <https://ignite.apache.org/docs/latest/thin-clients/java-thin-client>
It seems this could help igniteClient.cluster().forServers().nodes().count();
Best regards,
Aleksandr
