Grafana Dashboard

There's currently one plugin included with Timera, ``httptimer``.

With ``httptimer``, you can store the time it takes to get http responses. For example:

.. code-block:: ini

[httptimer_plugin_01]
name = www.google.com
url = https://www.google.com/
proxy = http://proxy.example.com:3128/
include_direct = true

See the config file, `config.ini <https://github.com/natej/timera/blob/master/config.ini>`_, for options.

Use any InfluxDB-compatible visualization software to view your metrics. For example:

- `Chronograf <https://portal.influxdata.com/downloads>`_
- `Grafana <http://docs.grafana.org/features/datasources/influxdb/>`_

Plugins
-------

Timera has a simple plugin system. So it's easy to write your own plugin to collect and store the metrics you want.
See the custom plugin below and the included plugin
`httptimer <https://github.com/natej/timera/blob/master/timera/plugins/httptimer/>`_ for examples.

Config file:

.. code-block:: ini

[mymetrics_plugin_01]
plugin_import = mymetrics.metrics
name = cpu_load_short
field = value

``mymetrics/metrics.py``:

.. code-block:: python

import logging
import timera

log = logging.getLogger(__name__)

def get_metrics(config, timestamp, plugin):
"""
:param config: ConfigParser instance
:param timestamp: unix timestamp (seconds since epoch) for current collection interval
:param plugin: dict with parsed plugin values
"""
measurement = plugin['config']['name']
field = plugin['config']['field']
metric = 0.64
fields = {field: str(metric)}
tags = {'host': 'server01', 'region': 'us-west'}
log.info('%s %r: %s=%f' % (measurement, tags, field, metric))
measurementd = dict(measurement=measurement, time=timestamp, fields=fields, tags=tags)
idbc = timera.db.get_client(config)
timera.db.write_points(idbc, [measurementd])

If you create a plugin you think others would find useful, please submit a PR with tests for inclusion in Timera.

Requirements
------------

- `InfluxDB <https://portal.influxdata.com/downloads>`_
- `Python <https://www.python.org/>`_ 2.7 or 3.6, pip and setuptools.

Install
-------

.. code-block:: bash

$ pip install timera

Or if using a virtual environment:

.. code-block:: bash

$ source env/bin/activate
$ pip install timera

Development Install
-------------------

Use ``make install-dev`` to install in editable mode (``pip install -e .``) with pytest and tox:

.. code-block:: bash

$ source env/bin/activate
$ cd timera-master
$ make install-dev
$ make test
$ tox

Run It
------

Create db and start collecting metrics:

.. code-block:: bash

# edit config.ini
$ timera config.ini reset_db
$ timera config.ini start

Optional
--------

Use `Supervisor <https://github.com/Supervisor/supervisor>`_ to run Timera. See the
`contrib dir <https://github.com/natej/timera/blob/master/contrib/>`_. Supervisor requires
Python 2 (``pip install supervisor``).

Viewing Metrics with Grafana
----------------------------

Configure `InfluxDB as a datasource <http://docs.grafana.org/features/datasources/influxdb/>`_.

For the ``httptimer`` plugin, create a `graph panel <http://docs.grafana.org/features/panels/graph/>`_ and
configure the query:
