prometheus-http-client 1.0.0

Prometheus service http client, author liyuanjun

# Prometheus-http-client [][travis]
> Prometheus service http client

* More simple expansion: use wrapper Automatic selection query mode, there is no need for any implementation.
```python
@prom
def go_gc_duration_seconds(self, **kwargs):
pass

@prom
def go_gc_duration_seconds_count(self, **kwargs):
pass

```

* Custom query expression: there is no need for any implementation.
```python
@relabel('100 - (avg by (instance, job) (irate(node_cpu{mode="idle"}[5m])) * 100)')
def node_cpu_rate(self, **kwargs):
pass

@relabel(
'(node_filesystem_size{} - node_filesystem_free{})'
' / (node_filesystem_size{} - node_filesystem_free{} + node_filesystem_avail{})'
' * 100')
def node_disk_rate(self, **kwargs):
pass
```

* Rich query selector: Support multi label query.
```python
from prometheus_http_client import NodeExporter

# default metric
node_exporter = NodeExporter()

# instance = 127.0.0.1:9100
# job = static
# mode = user
print(node_exporter.node_cpu_rate(filter={'instance': '127.0.0.1:9100','mode':'user','job':'static'}))
```


## Install
* source:
```shell
$ git clone https://github.com/tomoncle/prometheus-http-client.git
$ cd prometheus-http-client && sudo python setup.py install
```

* pip: `$ pip install prometheus-http-client`

## Config
* default config : 'http://localhost:9090'

* change config :
```bash
$ export PROMETHEUS_URL='http://192.168.1.2:9090'
```

* auth config :
```bash
$ export PROMETHEUS_HEAD='{"Cookie": "123456"}'
```

## Query
### Prometheus
```python
from prometheus_http_client import Prometheus


# auto metric
prometheus = Prometheus()
# print(prometheus.query(metric='sum by (mode, instance,job) (irate(node_cpu{job="static_nodes"}[5m]))'))
print(prometheus.query(metric='irate(node_cpu{job="static_nodes"}[5m])'))
```
