Hi All
I'm about to finish writing a small benchmark framework built on top of
whirr (very simple, uploads data to the cloud, prepares client and server
clusters, runs clients against servers and uploads results to the cloud before
destroying all the clusters).
In the final stage I need to extract the metrics and log output of
every node in the cluster and put them in cloud storage (e.g., s3) but I'd like
to package them with the cluster name and node name such as:
[bench]-[cluster]-[node]-metrics.tar.gz.
I was implementing the packaging and uploading of these files as
statements, but I'm having trouble finding the [cluster] and [node] ids.
Are these env variables or something I can get when I run the ssh
commands? orf is there some form of knowing against which node a statement is
being executed (if I call a statement with
clusterController.runScriptOnNodesMathing(… stmt)).
Cheers
