Monstache auto sync issue with elastic search

How can I make Monstache auto-sync new documents and collections in MongoDB to Elasticsearch without restarting the service?

I'm currently using Monstache to sync data from MongoDB to Elasticsearch. The initial sync works fine — all existing data gets indexed in Elasticsearch. However, when I insert new documents or create new collections in MongoDB, they are not automatically synced to Elasticsearch.

The only way I can get new data to appear in Elasticsearch is by restarting the Monstache service. This defeats the purpose of real-time syncing.

I've already configured Monstache to run as a systemd service, and the connection itself is working. What I need is for Monstache to continuously sync all changes (inserts, updates, and new collections) without requiring a restart.

Has anyone faced this issue? Is there a config setting or workaround to enable full real-time syncing, even when new collections or documents are added?
