Roll up index

[elasticforme (Sachin)]

I have turn on roll up job for testing

when I do GET /_rollup/job/_all
I can see it is running. it says started but I don't see any rollup index.
I don't see any index named metricbeat-rollup

how do I confirm that it is running or not

"jobs" : [
    {
      "config" : {
        "id" : "metricbeat-rollup",
        "index_pattern" : "metricbeat_*",
        "rollup_index" : "metricbeat-rollup",
        "cron" : "0 0 0 ? * 6",

          }
        },

anyone has any idea.
whole week pass and I don't see any new index with _rollup.

[elasticforme (Sachin)]

still no change. created new job and setup daily roll up and reduce time to 15 min rollup still nothing.

should it be creating new index or just roll up data on existing index?

[elasticforme (Sachin)]

anyone is using this at all?

What is this means

is it running? if it is should it be creating new index?
