The Phloem cloud — nothing to install

Lets you and Hamming search an Elasticsearch cluster, with each index's fields listed in Trace.

#What Phloem reads

• Every index, with its mapped fields, document count and size, listed in Trace
• Indices starting with . are left out

Phloem only searches. It never writes to the cluster.

#What you need

• A self-managed cluster's host and port (default 9200), reachable from Phloem's cloud, or an Elastic Cloud deployment's Cloud ID and an API key
• A username and password, or an API key, that can read the indices

#Connect

1. In the console, open Connectors, choose Add connector, then Elasticsearch.
2. Enter a Display Name.
3. Under Authentication Method, choose:
   • Username & Password — Host, Port, Username and Password
   • API Key — Host, Port and API Key
   • Elastic Cloud — Cloud ID and API Key
4. Leave Verify SSL Certificates on unless the cluster uses a self-signed certificate.
5. Choose Test Connection (it shows the cluster name and health), then Create Connection.

#What Hamming can do

• Search with JSON that you or Hamming write: {"index": "logs", "query": {"match_all": {}}, "size": 100}. query is Query DSL; sort is optional.

#Notes

• A search returns 100 hits unless it sets size.
• A search returns matching documents only, not aggregations.
• With Host, Phloem connects over plain HTTP. For a cluster that accepts only HTTPS, use Elastic Cloud.

#Connection fields

What the Add connector form asks for.
