# Local Metrics

Run these examples from the `samples` folder at the root of the repo.

This notebook tests the exposed Prometheus metrics of model and pipeline servers.

Requires: `prometheus_client` and `requests` libraries.\
See docs for full set of metrics available.

```python
mlserver_metrics_host="0.0.0.0:9006"
triton_metrics_host="0.0.0.0:9007"
pipeline_metrics_host="0.0.0.0:9009"
```

```python
from prometheus_client.parser import text_string_to_metric_families
import requests

def scrape_metrics(host):
    data = requests.get(f"http://{host}/metrics").text
    return {
        family.name: family for family in text_string_to_metric_families(data)
    }

def print_sample(family, label, value):
    for sample in family.samples:
        if sample.labels[label] == value:
            print(sample)

def get_model_infer_count(host, model_name):
    metrics = scrape_metrics(host)
    family = metrics["seldon_model_infer"]
    print_sample(family, "model", model_name)

def get_pipeline_infer_count(host, pipeline_name):
    metrics = scrape_metrics(host)
    family = metrics["seldon_pipeline_infer"]
    print_sample(family, "pipeline", pipeline_name)
```

### MLServer Model

```bash
seldon model load -f ./models/sklearn-iris-gs.yaml
seldon model status iris -w ModelAvailable | jq -M .
```

```json
{}
{}

### Triton Model

Load the model.

```bash
seldon model load -f ./models/tfsimple1.yaml
seldon model status tfsimple1 -w ModelAvailable | jq -M .
```

```json
{}
{}

```

```bash
seldon model infer tfsimple1 -i 50\
    '{"inputs":[{"name":"INPUT0","data":[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16],"datatype":"INT32","shape":[1,16]},{"name":"INPUT1","data":[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16],"datatype":"INT32","shape":[1,16]}]}'

### Pipeline

```bash
seldon model load -f ./models/tfsimple1.yaml

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.seldon.ai/seldon-core-2/user-guide/operational-monitoring/local-metrics-test.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
