It retrieves metrics periodically from Redis (or sentinel) (such as latency, connected_clients, instantaneous_ops_per_sec and others) and send them to Logstash.

}| Variable | Mandatory | Description |
|---|---|---|
| PROJECT | Y | An identifier for the metrics. It'll be send as "client": PROJECT + "-redis" |
| PING_FREQUENCY | Frequency in seconds that the metrics are fetched. Default: 10 |
|
| REDIS_HOST | Y | Redis host with port. If you're using redis sentinel, then REDIS_HOST will host the sentinel hosts separated by commas ("host:port,host:port") |
| REDIS_PWD | Redis password. Default: "" |
|
| REDIS_SENTINEL | Whether you're using sentinel or not. Default: "" |
|
| REDIS_MASTER_NAME | Redis sentinel master name. Default: "" |
|
| REDIS_LATENCY_THRESHOLD | Redis latency threshold in ms. When any command take longer than the threshold, then it sends data about latency. After PING_FREQUENCY has passed, it sends 0.Default: "" |
|
| REDIS_METRICS_TO_WATCH | The fields you want to keep track from the output of the command "info". Default: "client_longest_output_list,connected_clients,blocked_clients,rejected_connections,instantaneous_input_kbps,instantaneous_output_kbps,instantaneous_ops_per_sec,keyspace_hits,keyspace_misses,mem_fragmentation_ratio,sync_full,sync_partial_ok,sync_partial_err" |
|
| LOGSTASH_HOST | Y | Logstash host |
| LOGSTASH_PORT | Y | Logstash port |
| LOGSTASH_PROTOCOL | The transport protocol used by logstash. Default: "udp" |
