# 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 specifed, HTTP is used. ## If no port is specified, 8091 is used. servers = ["http://localhost:8091"] ``` ## Measurements: ### couchbase_node Tags: - cluster: whatever you called it in `servers` in the configuration, e.g.: `http://couchbase-0.example.com/` - 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 ``` $ telegraf -config telegraf.conf -input-filter couchbase -test * Plugin: couchbase, Collection 1 > couchbase_node,cluster=https://couchbase-0.example.com/,hostname=172.16.10.187:8091 memory_free=22927384576,memory_total=64424656896 1458381183695864929 > couchbase_node,cluster=https://couchbase-0.example.com/,hostname=172.16.10.65:8091 memory_free=23520161792,memory_total=64424656896 1458381183695972112 > couchbase_node,cluster=https://couchbase-0.example.com/,hostname=172.16.13.105:8091 memory_free=23531704320,memory_total=64424656896 1458381183695995259 > couchbase_node,cluster=https://couchbase-0.example.com/,hostname=172.16.13.173:8091 memory_free=23628767232,memory_total=64424656896 1458381183696010870 > couchbase_node,cluster=https://couchbase-0.example.com/,hostname=172.16.15.120:8091 memory_free=23616692224,memory_total=64424656896 1458381183696027406 > couchbase_node,cluster=https://couchbase-0.example.com/,hostname=172.16.8.127:8091 memory_free=23431770112,memory_total=64424656896 1458381183696041040 > couchbase_node,cluster=https://couchbase-0.example.com/,hostname=172.16.8.148:8091 memory_free=23811371008,memory_total=64424656896 1458381183696059060 > couchbase_bucket,bucket=default,cluster=https://couchbase-0.example.com/ data_used=25743360,disk_fetches=0,disk_used=31744886,item_count=0,mem_used=77729224,ops_per_sec=0,quota_percent_used=10.58976636614118 1458381183696210074 > couchbase_bucket,bucket=demoncat,cluster=https://couchbase-0.example.com/ data_used=38157584951,disk_fetches=0,disk_used=62730302441,item_count=14662532,mem_used=24015304256,ops_per_sec=1207.753207753208,quota_percent_used=79.87855353525707 1458381183696242695 > couchbase_bucket,bucket=blastro-df,cluster=https://couchbase-0.example.com/ data_used=212552491622,disk_fetches=0,disk_used=413323157621,item_count=944655680,mem_used=202421103760,ops_per_sec=1692.176692176692,quota_percent_used=68.9442170551845 1458381183696272206 ```
