Grafana Loki

Grafana Loki Destination Plugin

Grafana Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by Prometheus. It allows you to store and query logs using labels to filter and aggregate log data, making it easy to explore and visualize your logs in Grafana. The Grafana Loki Destination Plugin in Calyptia Core allows you to seamlessly integrate your telemetry data with Grafana Loki, enabling you to store, analyze, and visualize your log data using Grafana's powerful logging tools. With the Grafana Loki Destination Plugin, you can easily configure your Calyptia Core pipeline to send your log data to Grafana Loki,

Key
Description
Tenant ID
Tenant ID used by default to push logs to Loki. If omitted or empty it assumes Loki is running in single-tenant mode and no X-Scope-OrgID header is sent.
Tenant ID Key
If set, X-Scope-OrgID will be the value of the key from incoming record. It is useful to set X-Scode-OrgID dynamically
Labels
labels for API requests, If no value is set the default label is job=fluent-bit
Label Keys
Comma-separated list of keys to use as stream labels
Enable Auto Kubernetes Labels
If set to true, it will add all Kubernetes labels to Loki labels.
Drop Single Key
If set to true and only a single key remains, the log line sent to Loki will be the value of that key.
Remove Keys
Comma separated list of keys to remove
Line Format
Format to use when flattening the record to a log line. Valid values are 'json' or 'key_value'. If set to 'json' the log line sent to Loki will be the Fluent Bit record dumped as json. If set to 'key_value', the log line will be each item in the record concatenated together (separated by a single space) in the format '='.
