# Telegraf Plugin: Couchbase ## Configuration: ``` # Read per-node and per-bucket metrics from Couchbase [[inputs.couchbase]] ## specify servers via a url matching: ## [protocol://][:password]@address[:port] ## e.g. ## http://couchbase-0.example.com/ ## http://admin:secret@couchbase-0.example.com:8091/ ## ## If no servers are specified, then localhost is used as the host. ## If no protocol is specified, HTTP is used. ## If no port is specified, 8091 is used. servers = ["http://localhost:8091"] ``` ## Measurements: ### couchbase_node Tags: - cluster: sanitized string from `servers` configuration field e.g.: `http://user:password@couchbase-0.example.com:8091/endpoint` -> `http://couchbase-0.example.com:8091/endpoint` - hostname: Couchbase's name for the node and port, e.g., `172.16.10.187:8091` Fields: - memory_free (unit: bytes, example: 23181365248.0) - memory_total (unit: bytes, example: 64424656896.0) ### couchbase_bucket Tags: - cluster: whatever you called it in `servers` in the configuration, e.g.: `http://couchbase-0.example.com/`) - bucket: the name of the couchbase bucket, e.g., `blastro-df` Fields: - quota_percent_used (unit: percent, example: 68.85424936294555) - ops_per_sec (unit: count, example: 5686.789686789687) - disk_fetches (unit: count, example: 0.0) - item_count (unit: count, example: 943239752.0) - disk_used (unit: bytes, example: 409178772321.0) - data_used (unit: bytes, example: 212179309111.0) - mem_used (unit: bytes, example: 202156957464.0) ## Example output ``` couchbase_node,cluster=http://localhost:8091/,hostname=172.17.0.2:8091 memory_free=7705575424,memory_total=16558182400 1547829754000000000 couchbase_bucket,bucket=beer-sample,cluster=http://localhost:8091/ quota_percent_used=27.09285736083984,ops_per_sec=0,disk_fetches=0,item_count=7303,disk_used=21662946,data_used=9325087,mem_used=28408920 1547829754000000000 ```
