This also adds support for both the v1 and v2 APIs to set the Proxy
function on the underlying http.Transport.
The functionality for proxy environment variables is provided by the
[http.ProxyFromEnvironment](https://godoc.org/net/http#ProxyFromEnvironment).
The default port for HTTP is 80 and HTTPS is 443. When you host InfluxDB
on a service that uses a reverse proxy, the `Host` header needs to be
exactly correct. Since the host header isn't expecting to see the port
when it is the default, this causes routing to fail.
The string `node <n>` can be used to specify which data node the data
should be retrieved from. This uses the `node_id=X` query parameter that
is supported, but wasn't exposed anywhere in the client library.
We use this feature enough internally when attempting to find
inconsistencies or network errors that it is easier if this is just
supported. Otherwise, I continue having to recompile the CLI program
every time I need to do this.
To clear a previously set node, you can use `node 0` or `node clear`.
When a downstream server such as a proxy or loadbalancer between
influxdb and the client produces an error, the client currently does
not make this very obvious.
This change introduces checks on both the content type and the
influx version header to identify whether a request was served by
influxdb itself and returns a more appropriate error in the cases
where it can be determined a downstream issue is at play.
Measurement name and field were converted between []byte and string
repetively causing lots of garbage. This switches the code to use
[]byte in the write path.
Hello,
I have tried this example as it is for now. Encountered an error that AddPoint function expects only one argument. Checked you GoDoc and updated the example in your error handling style. It works like this.
* Added additional variable to fulfil NewUDPClient function requirement (there was one instead of 2) and it caused multiple-value client.NewUDPClient() in single-value context error
* Update README.md
Added error handling.
The v2 UDP client will attempt to split points that exceed the
configured payload size. It will only do this for points that have a
timestamp specified.
In order to follow REST a bit more carefully, all write operations
should go through a POST in the future. We still allow read operations
through either GET or POST (similar to the Graphite /render endpoint),
but write operations will trigger a returned warning as part of the JSON
response and will eventually return an error.
Also updates the Golang client libraries to always use POST instead of
GET.
Fixes#6290.
If users properly call client.Close(), then this will make sure that
established tcp connections dont continually grow when creating new http
clients.
This fixes the case where users are creating new http clients on top of
existing _valid_ connections.
This was encountered in Telegraf when we were recreating our http
clients after getting write failures that were unrelated to the actual
connection being severed (such as typos in the retention policy, see
https://github.com/influxdata/telegraf/issues/1058)
The deprecated message is now attached to a new attribute returned with
the results. This message can then be read by clients to warn a user
about upcoming changes to the query engine.
The `influx` client has already been modified to read this message and
print it out for every format except CSV.
The first warning message is a deprecated message about removing `IF NOT
EXISTS` from `CREATE DATABASE`.
The message will also be printed to the server log.
Fixes#5707.
