grafana-redistimeseries's Introduction

Deprecation notice

This project has been deprecated, for further information on how to use Redis and Grafana: https://github.com/RedisTimeSeries/grafana-redis-datasource.

RedisTimeSeries-Datasource

Grafana Datasource for RedisTimeSeries

QuickStart

You can tryout the Grafana Datasource for RedisTimeSeries with RedisTimeSeries and Grafana in a single docker compose

cd compose
docker-compose up

Grafana can be accessed on port 3000 (admin:admin)

Grafana Datastore API Server

Overview

A HTTP Server to serve metrics to Grafana via the simple-json-datasource

Grafana configuration

install SimpleJson data source: https://grafana.net/plugins/grafana-simple-json-datasource/installation
in Grafana UI, go to Data Sources
Click Add data source 3.1 choose Name 3.2 Type: SimpleJson 3.3 URL: point to the URL for your GrafanaDatastoreServer.py 3.4 Access: direct (unless you are using a proxy)
Query the datasource by a specific key, or * for a wildcard, for example: stats_counts.http.*

Dependencies

To install the needed dependencies just run: pip install -r requirements.txt

GrafanaDatastoreServer.py Usage

usage: GrafanaDatastoreServer.py [-h] [--host HOST] [--port PORT]
                                 [--redis-server REDIS_SERVER]
                                 [--redis-port REDIS_PORT]

optional arguments:
  -h, --help            show this help message and exit
  --host HOST           server address to listen to
  --port PORT           port number to listen to
  --redis-server REDIS_SERVER
                        redis server address
  --redis-port REDIS_PORT
                        redis server port

Note about timezone

Grafana uses UTC timestamps to query its datastores. This datastore will use the same timestamps to query Redis, which means that it assumes all timestamps are UTC based.

grafana-redistimeseries's Issues

create a docker compose

including this, RTS and Grafana similar to https://github.com/RedisTimeSeries/prometheus-redistimeseries-adapter/tree/master/compose

TypeError: can't subtract offset-naive and offset-aware datetimes

After adding data source, when trying to fetch metric:

redis time series update generates error in both grafana-redistimeseries and grafana

Hi,
Using macosx as the server for the data source, redis, redis-grafana, and grafana.
the data is a floating point value updating at 1hz.

grafana reports "internal error" in a red triangle at the upper left corner, and this message
in the console:
EROR[09-26|14:14:39] Request Completed logger=context userId=1 orgId=1 uname=admin method=POST path=/api/datasources/proxy/1/query status=500 remote_addr=[::1] time_ms=10 size=291 referer="http://localhost:3000/?orgId=1"

the grafana-redis server exceptions reporting this message:

flask blows up with naive time

I tried this, with the same error, on both macosx and ubuntu.

Problem occurs when I select "timeserie" in the grafana dashboard
Help please. Thank you

Consider a new release?

There were 11 commits since 0.1.0 and some of them were bug fixes. No new changes since August.

help with README.md

Step 3.3 says: URL: point to the URL for your GrafanaDatastoreServer.py

At this point I am completely lost.

I see GrafanaDatastoreServer.py - this is a file in a directory I downloaded.
But I have no clue as to what URL this corresponds to.

Do I need to create a webserver and expose this file?
