Prometheus Pandas

Python library for querying Prometheus and accessing the results as Pandas data structures.

This is mostly intended for use in Jupyter notebooks. See Prometheus.ipynb for an example.

Example

Evaluate an instant query at a single point in time:

>>> from prometheus_pandas import query
>>>
>>> p = query.Prometheus('http://localhost:9090')
>>> p.query('node_cpu_seconds_total{mode="system"}', '2020-05-10T00:00:00Z')
node_cpu_seconds_total{cpu="0",instance="localhost:9100",job="node",mode="system"}    15706.47
node_cpu_seconds_total{cpu="1",instance="localhost:9100",job="node",mode="system"}    15133.25
node_cpu_seconds_total{cpu="2",instance="localhost:9100",job="node",mode="system"}    15095.59
node_cpu_seconds_total{cpu="3",instance="localhost:9100",job="node",mode="system"}    14649.20
dtype: float64

Evaluates an expression query over a time range:

>>> from prometheus_pandas import query
>>>
>>> p = query.Prometheus('http://localhost:9090')
>>> print(p.query_range(
        'sum(rate(node_cpu_seconds_total{mode=~"system|user"}[1m])) by (mode)',
        '2020-10-05T00:00:00Z', '2020-10-05T06:00:00Z', '1h'))
dtype: float64

2020-10-05 06:00:00         0.018222       0.035111

Customizing the HTTP request:

>>> import requests
>>> from prometheus_pandas import query
>>>
>>> http = requests.Session()
>>> http.cert = '/path/client.cert'
>>> http.verify = '/path/to/certfile'
>>>
>>> p = query.Prometheus('http://localhost:9090', http)
>>> print(p.query('node_cpu_seconds_total{mode="system"}', '2020-10-05T00:00:00Z'))
node_cpu_seconds_total{cpu="0",instance="localhost:9100",job="node",mode="system"}    3954.92
dtype: float64
