PyPromql - Python PromQL Query Builder

Abstract

Installation

To install PyPromql run the following command:

    pip install pypromql

Tutorial

The main classes in pypromql are pypromql.query.Query and pypromql.result.PrometheusResult.

    from pypromql.query import Query
    from pypromql.result import PrometheusResult

Create simple query

The entry point for building queries is pypromql.query.Query.

    promql_query = Query.metric('up').label('job', 'prometheus')

    up{job="prometheus"}

To convert the query into raw PromQL, it can be cast to a string.

    str(promql_query)

Alternatively, you can use the to_promql() function:

    promql_query.to_promql()

Execute query

First, we need to create a pypromql.PrometheusConnection.

    connection = PrometheusConnection(prometheus_base_url='http://my-host-name:my-port/')

Then, we execute our query and get the result using PrometheusResult.from_query_builder.

    result = PrometheusResult.from_query_builder(promql_query, connection)
