influxdb output: treat field type conflicts as a successful write
If we write a batch of points and get a "field type conflict" error message in return, we should drop the entire batch of points because this indicates that one or more points have a type that doesnt match the database. These errors will never go away on their own, and InfluxDB will successfully write the points that dont have a conflict. closes #2245

-## v1.3 [unreleased]
-
-### Release Notes
-
- Users of the windows `ping` plugin will need to drop or migrate their
-measurements in order to continue using the plugin. The reason for this is that
-the windows plugin was outputting a different type than the linux plugin. This
-made it impossible to use the `ping` plugin for both windows and linux
-machines.
-
- Ceph: the `ceph_pgmap_state` metric content has been modified to use a unique field `count`, with each state expressed as a `state` tag.
-
-Telegraf < 1.3:
-
-```
-# field_name             value
-active+clean             123
-active+clean+scrubbing   3
-```
-
-Telegraf >= 1.3:
-
-```
-# field_name    value       tag
-count           123         state=active+clean
-count           3           state=active+clean+scrubbing
-```
-
- The [Riemann output plugin](./plugins/outputs/riemann) has been rewritten
-and the previous riemann plugin is _incompatible_ with the new one. The reasons
-for this are outlined in issue [#1878](https://github.com/influxdata/telegraf/issues/1878).
-The previous riemann output will still be available using
-`outputs.riemann_legacy` if needed, but that will eventually be deprecated.
-It is highly recommended that all users migrate to the new riemann output plugin.
-
- Generic [socket_listener](./plugins/inputs/socket_listener) and
-[socket_writer](./plugins/outputs/socket_writer) plugins have been implemented
-for receiving and sending UDP, TCP, unix, & unix-datagram data. These plugins
-will replace udp_listener and tcp_listener, which are still available but will
-be deprecated eventually.

-
-Metrics are read from a topic exchange using the configured queue and binding_key.
-
-Message payload should be formatted in one of the [Telegraf Data Formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
-
-For an introduction to AMQP see:
- https://www.rabbitmq.com/tutorials/amqp-concepts.html
- https://www.rabbitmq.com/getstarted.html
-
-The following defaults are known to work with RabbitMQ:
-
-```toml
-# AMQP consumer plugin
-[[inputs.amqp_consumer]]
-  ## AMQP url
-  url = "amqp://localhost:5672/influxdb"
-  ## AMQP exchange
-  exchange = "telegraf"
-  ## AMQP queue name
-  queue = "telegraf"
-  ## Binding Key
-  binding_key = "#"
-
-  ## Controls how many messages the server will try to keep on the network
-  ## for consumers before receiving delivery acks.
-  #prefetch_count = 50
-
-  ## Auth method. PLAIN and EXTERNAL are supported.
-  ## Using EXTERNAL requires enabling the rabbitmq_auth_mechanism_ssl plugin as
-  ## described here: https://www.rabbitmq.com/plugins.html
-  # auth_method = "PLAIN"
-  ## Optional SSL Config
-  # ssl_ca = "/etc/telegraf/ca.pem"
-  # ssl_cert = "/etc/telegraf/cert.pem"
-  # ssl_key = "/etc/telegraf/key.pem"
-  ## Use SSL but skip chain & host verification
-  # insecure_skip_verify = false
-
-  ## Data format to output.
-  ## Each data format has it's own unique set of configuration options, read
-  ## more about them here:
-  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
-  data_format = "influx"

 The iptables plugin gathers packets and bytes counters for rules within a set of table and chain from the Linux's iptables firewall.

-Indeed we need a unique ID for the rule and the rule number is not a constant: it may vary when rules are inserted/deleted at start-up or by automatic tools (interactive firewalls, fail2ban, ...).
-Also when the rule set is becoming big (hundreds of lines) most people are interested in monitoring only a small part of the rule set.

-Specify address via a url matching:
-
-  `postgres://[pqgotest[:password]]@localhost[/dbname]?sslmode=[disable|verify-ca|verify-full]`
-
-All connection parameters are optional. Without the dbname parameter, the driver will default to a database with the same name as the user. This dbname is just for instantiating a connection with the server and doesn't restrict the databases we are trying to grab metrics for.
-
-A  list of databases to explicitly ignore.  If not specified, metrics for all databases are gathered.  Do NOT use with the 'databases' option.

-# socket listener service input plugin
-
-The Socket Listener is a service input plugin that listens for messages from
-streaming (tcp, unix) or datagram (udp, unixgram) protocols.
-
-The plugin expects messages in the
-[Telegraf Input Data Formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
-
-### Configuration:
-
-This is a sample configuration for the plugin.
-
-```toml
-# Generic socket listener capable of handling multiple socket types.
-[[inputs.socket_listener]]
-  ## URL to listen on
-  # service_address = "tcp://:8094"
-  # service_address = "tcp://127.0.0.1:http"
-  # service_address = "tcp4://:8094"
-  # service_address = "tcp6://:8094"
-  # service_address = "tcp6://[2001:db8::1]:8094"
-  # service_address = "udp://:8094"
-  # service_address = "udp4://:8094"
-  # service_address = "udp6://:8094"
-  # service_address = "unix:///tmp/telegraf.sock"
-  # service_address = "unixgram:///tmp/telegraf.sock"
-
-  ## Maximum number of concurrent connections.
-  ## Only applies to stream sockets (e.g. TCP).
-  ## 0 (default) is unlimited.
-  # max_connections = 1024
-
-  ## Maximum socket buffer size in bytes.
-  ## For stream sockets, once the buffer fills up, the sender will start backing up.
-  ## For datagram sockets, once the buffer fills up, metrics will start dropping.
-  ## Defaults to the OS default.
-  # read_buffer_size = 65535
-
-  ## Data format to consume.
-  ## Each data format has it's own unique set of configuration options, read
-  ## more about them here:
-  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
-  # data_format = "influx"
-```
-
-## A Note on UDP OS Buffer Sizes
-
-The `read_buffer_size` config option can be used to adjust the size of the socket
-buffer, but this number is limited by OS settings. On Linux, `read_buffer_size`
-will default to `rmem_default` and will be capped by `rmem_max`. On BSD systems,
-`read_buffer_size` is capped by `maxsockbuf`, and there is no OS default
-setting.
-
-Instructions on how to adjust these OS settings are available below.
-
-Some OSes (most notably, Linux) place very restricive limits on the performance
-of UDP protocols. It is _highly_ recommended that you increase these OS limits to
-at least 8MB before trying to run large amounts of UDP traffic to your instance.
-8MB is just a recommendation, and can be adjusted higher.
-
-### Linux
-Check the current UDP/IP receive buffer limit & default by typing the following
-commands:
-
-```
-sysctl net.core.rmem_max
-sysctl net.core.rmem_default
-```
-
-If the values are less than 8388608 bytes you should add the following lines to
-the /etc/sysctl.conf file:
-
-```
-net.core.rmem_max=8388608
-net.core.rmem_default=8388608

-### BSD/Darwin
-
-On BSD/Darwin systems you need to add about a 15% padding to the kernel limit
-socket buffer. Meaning if you want an 8MB buffer (8388608 bytes) you need to set
-the kernel limit to `8388608*1.15 = 9646900`. This is not documented anywhere but
-happens
-[in the kernel here.](https://github.com/freebsd/freebsd/blob/master/sys/kern/uipc_sockbuf.c#L63-L64)
-
-Check the current UDP/IP buffer limit by typing the following command:
-
-```
-sysctl kern.ipc.maxsockbuf
-```
-
-If the value is less than 9646900 bytes you should add the following lines
-to the /etc/sysctl.conf file (create it if necessary):
-
-```
-kern.ipc.maxsockbuf=9646900
-```
-
-Changes to /etc/sysctl.conf do not take effect until reboot.
-To update the values immediately, type the following command as root:
-
-```
-sysctl -w kern.ipc.maxsockbuf=9646900

-# DiskIO Input Plugin
-
-The diskio input plugin gathers metrics about disk traffic and timing.
-
-### Configuration:
-
-```
-# Read metrics about disk IO by device
-[[inputs.diskio]]
-  ## By default, telegraf will gather stats for all devices including
-  ## disk partitions.
-  ## Setting devices will restrict the stats to the specified devices.
-  # devices = ["sda", "sdb"]
-  ## Uncomment the following line if you need disk serial numbers.
-  # skip_serial_number = false
-```
-
-Data collection is based on github.com/shirou/gopsutil. This package handles platform dependencies and converts all timing information to milliseconds.
-
-
-### Measurements & Fields:
-
- diskio
-    - reads (integer, counter)
-    - writes (integer, counter)
-    - read_bytes (integer, bytes)
-    - write_bytes (integer, bytes)
-    - read_time (integer, milliseconds)
-    - write_time (integer, milliseconds)
-    - io_time (integer, milliseconds)
-    - iops_in_progress (integer, counter) (since #2037, not yet in STABLE)
-
-### Tags:
-
- All measurements have the following tags:
-    - name (device name)
- If configured to use serial numbers (default: disabled):
-    - serial (device serial number)
-
-### Example Output:

 # UDP listener service input plugin

-> DEPRECATED: As of version 1.3 the UDP listener plugin has been deprecated in favor of the
-> [socket_listener plugin](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/socket_listener)
+The UDP listener is a service input plugin that listens for messages on a UDP

+
+## A Note on UDP OS Buffer Sizes
+
+Some OSes (most notably, Linux) place very restricive limits on the performance
+of UDP protocols. It is _highly_ recommended that you increase these OS limits to
+at least 8MB before trying to run large amounts of UDP traffic to your instance.
+8MB is just a recommendation, and can be adjusted higher.
+
+### Linux
+Check the current UDP/IP receive buffer limit & default by typing the following
+commands:
+
+```
+sysctl net.core.rmem_max
+sysctl net.core.rmem_default
+```
+
+If the values are less than 8388608 bytes you should add the following lines to
+the /etc/sysctl.conf file:
+
+```
+net.core.rmem_max=8388608
+net.core.rmem_default=8388608
+```
+
+Changes to /etc/sysctl.conf do not take effect until reboot.
+To update the values immediately, type the following commands as root:
+
+```
+sysctl -w net.core.rmem_max=8388608
+sysctl -w net.core.rmem_default=8388608
+```
+
+### BSD/Darwin
+
+On BSD/Darwin systems you need to add about a 15% padding to the kernel limit
+socket buffer. Meaning if you want an 8MB buffer (8388608 bytes) you need to set
+the kernel limit to `8388608*1.15 = 9646900`. This is not documented anywhere but
+happens
+[in the kernel here.](https://github.com/freebsd/freebsd/blob/master/sys/kern/uipc_sockbuf.c#L63-L64)
+
+Check the current UDP/IP buffer limit by typing the following command:
+
+```
+sysctl kern.ipc.maxsockbuf
+```
+
+If the value is less than 9646900 bytes you should add the following lines
+to the /etc/sysctl.conf file (create it if necessary):
+
+```
+kern.ipc.maxsockbuf=9646900
+```
+
+Changes to /etc/sysctl.conf do not take effect until reboot.
+To update the values immediately, type the following commands as root:
+
+```
+sysctl -w kern.ipc.maxsockbuf=9646900

Cameron Sparr	10d0a78b96	influxdb output: treat field type conflicts as a successful write If we write a batch of points and get a "field type conflict" error message in return, we should drop the entire batch of points because this indicates that one or more points have a type that doesnt match the database. These errors will never go away on their own, and InfluxDB will successfully write the points that dont have a conflict. closes #2245	2017-01-23 18:26:37 -08:00
