# DESCRIPTION: Prometheus scrape job configuration for llama-swap's native
#              /metrics endpoint (OpenMetrics format).
#              
#              This template is rendered and deployed to the Prometheus
#              config via GitOps (cluster/applications/monitoring/values.yaml).
#              Does NOT include this file inline here; it is referenced and
#              rendered by Ansible roles/llm-inference-multimodel/tasks/*.yml.
#
# TARGET HOST: astro-orbiter ({{ llm_bind_address }}:{{ llm_swapmode_port }})
# METRICS:     llamacpp_tokens_predicted_total, llamacpp_kv_cache_usage_ratio,
#              llamacpp_time_predict_ms, llamacpp_queue_size, etc. (per llama.cpp)

# llama-swap exposes llamaswap_* metrics (GPU VRAM, utilization, power, CPU,
# network, load average). Per-model inference metrics are not available at the
