• Understanding the Pulse Elasticsearch data

By default, the pulse-server-state index is split by month. A new index will be created per month (pulse-server-state-2021-01, pulse-server-state-2021-02…).

If you are short in memory and instead of keeping only the last month of the pulse-server-state, you would like to keep the last 7 days. You will need to change the frequency of the pulse-server-state.

To do that, go to the <Pulse folder>/conf/Pulse.cfg file, update the ServerStateIndexPattern value from yyyy-MM to yyyy-MM-dddd.

Save the file end then restart the Pulse Application Server.

There is one setting in the Pulse.cfg per index:

The pulse-tm1-client-history is a unique index that has only the list of users.
