test again
well, we use it to store some time series data and visualize them using grafana (http://grafana.org/). since our data is not that big for now (several points in a second), everything works fine so far.
so currently the library is used just for inserting data.
at least an example how to send some data to the server
@wereHamster you can find a few examples in https://github.com/maoe/influxdb-haskell/blob/develop/examples/random-points.hs#L42-L51 and https://github.com/maoe/influxdb-haskell/blob/develop/tests/test-suite.hs#L103-L138
the
toSeriesColumns function has no access to the value, only the proxy, so I can't define different columns based on the constructor.
Ideally I would encode that point as
{type:'A', int: x} or {type:'B',string:x} or {type:'C',bool:x}
Okay, I understand your use case. Currently
ToDataSeries doesn't support sum types. I'm planning to change some data types and functions in the near future. I'll add the support for sum types then. As a quick workaround, I'll add a helper function in the next release so you can send SeriesData directly without having to use ToSeriesData type class.
Hi, I just released http://hackage.haskell.org/package/libinfluxdb, which works with influxdb 0.9 but only includes code for writing data (so no queries)
It's therefore really small, but includes everything one should need to write metrics data from an application to influxdb.
i haven't gotten around to looking at influxdb 0.9 yet but would like to fix the influxdb package in the near future. a guy is also interested in doing that in #23.
We're considering using InfluxDB for time series stock data
However, we just noticed that JOIN operations can be executed only on the time column. How do you get around this limitation?
Let's say you wanted to join different measurements on their stock ticker tag, or some ID?
yes, influxdb stopped allowing joining different measurements as of v0.9 or something. i think you can just use tags for ticker symbols. then if you select without the tag, you'll get all the stocks combined.
@odsogunro sorry for the delayed response. i didn't notice your message. yes, you can pass timestamps by putting them in the last field of the Line type: https://hackage.haskell.org/package/influxdb-1.2.2.2/docs/Database-InfluxDB-Line.html#t:Line
you can take a look at this example: https://hackage.haskell.org/package/influxdb-1.2.2.2/docs/Database-InfluxDB.html#v:write
here you can change
here you can change
Nothing :: Maybe UTCTime to whatever timestamp you have
