Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| query_loki_logsA | Run a Loki range query through Grafana datasource proxy. Args:
query: LogQL expression, e.g. Returns: JSON payload from Loki with streams and log entries. |
| query_loki_instantA | Run a Loki instant query through Grafana datasource proxy. Args: query: LogQL expression. limit: Maximum number of log lines to return (1–5000, default 100). at: Evaluation timestamp. RFC 3339 or Unix nanosecond string. Defaults to now when omitted. Returns: JSON payload from Loki with matching log entries. |
| list_loki_labelsA | List available Loki label names from the configured datasource. Args: start: Optional start of the time range for filtering. end: Optional end of the time range for filtering. Returns: JSON array of label name strings. |
| list_loki_label_valuesA | List available values for a given Loki label. Args:
label: Label name, e.g. Returns: JSON array of label value strings. |
| query_metricsA | Run an instant PromQL query against Thanos. Args:
query: PromQL expression, e.g. Returns:
JSON payload from Thanos containing |

TDQS
Scored across 8 tools
Each tool targets a distinct operation and data source (Loki vs. Thanos), with clear naming and descriptions that prevent confusion. Even similar tasks like label listing are differentiated by the datasource prefix.
All tools follow a consistent verb_noun pattern in snake_case, e.g., 'query_loki_instant', 'list_labels'. The naming clearly indicates the action and the target, making it predictable and easy to understand.
With 8 tools covering essential operations for two datasources (metrics and logs), the count is well-scoped. There are no redundant tools, and each tool serves a clear purpose without overwhelming the agent.
The tool set covers the core query and metadata exploration for both Loki and Thanos, including instant/range queries, label discovery, and series listing. No obvious gaps exist for standard observability workflows.
