+# ValueCounter Aggregator Plugin
+
+The valuecounter plugin counts the occurrence of values in fields and emits the
+counter once every 'period' seconds.
+
+A use case for the valuecounter plugin is when you are processing a HTTP access
+log (with the logparser input) and want to count the HTTP status codes.
+
+The fields which will be counted must be configured with the `fields`
+configuration directive. When no `fields` is provided the plugin will not count
+any fields. The results are emitted in fields in the format:
+`originalfieldname_fieldvalue = count`.
+
+Valuecounter only works on fields of the type int, bool or string. Float fields
+are being dropped to prevent the creating of too many fields.
+
+### Configuration:
+
+```toml
+[[aggregators.valuecounter]]
+  ## General Aggregator Arguments:
+  ## The period on which to flush & clear the aggregator.
+  period = "30s"
+  ## If true, the original metric will be dropped by the
+  ## aggregator and will not get sent to the output plugins.
+  drop_original = false
+  ## The fields for which the values will be counted
+  fields = ["status"]
+```
+
+### Measurements & Fields:
+
+- measurement1
+    - field_value1
+    - field_value2
+
+### Tags:
+
+No tags are applied by this aggregator.
+
+### Example Output:

+Example for parsing a HTTP access log.

+# Syslog Input Plugin
+
+The syslog plugin listens for syslog messages transmitted over
+[UDP](https://tools.ietf.org/html/rfc5426) or
+[TCP](https://tools.ietf.org/html/rfc5425).
+
+Syslog messages should be formatted according to
+[RFC 5424](https://tools.ietf.org/html/rfc5424).
+
+### Configuration
+
+```toml
+[[inputs.syslog]]
+  ## Specify an ip or hostname with port - eg., tcp://localhost:6514, tcp://10.0.0.1:6514
+  ## Protocol, address and port to host the syslog receiver.
+  ## If no host is specified, then localhost is used.
+  ## If no port is specified, 6514 is used (RFC5425#section-4.1).
+  server = "tcp://:6514"
+
+  ## TLS Config
+  # tls_allowed_cacerts = ["/etc/telegraf/ca.pem"]
+  # tls_cert = "/etc/telegraf/cert.pem"
+  # tls_key = "/etc/telegraf/key.pem"
+
+  ## Period between keep alive probes.
+  ## 0 disables keep alive probes.
+  ## Defaults to the OS configuration.
+  ## Only applies to stream sockets (e.g. TCP).
+  # keep_alive_period = "5m"
+
+  ## Maximum number of concurrent connections (default = 0).
+  ## 0 means unlimited.
+  ## Only applies to stream sockets (e.g. TCP).
+  # max_connections = 1024
+
+  ## Read timeout (default = 500ms).
+  ## 0 means unlimited.
+  # read_timeout = 500ms
+
+  ## Whether to parse in best effort mode or not (default = false).
+  ## By default best effort parsing is off.
+  # best_effort = false
+
+  ## Character to prepend to SD-PARAMs (default = "_").
+  ## A syslog message can contain multiple parameters and multiple identifiers within structured data section.
+  ## Eg., [id1 name1="val1" name2="val2"][id2 name1="val1" nameA="valA"]
+  ## For each combination a field is created.
+  ## Its name is created concatenating identifier, sdparam_separator, and parameter name.
+  # sdparam_separator = "_"
+```
+
+#### Best Effort
+
+The [`best_effort`](https://github.com/influxdata/go-syslog#best-effort-mode)
+option instructs the parser to extract partial but valid info from syslog
+messages.  If unset only full messages will be collected.
+

+
+### Rsyslog Integration
+
+Rsyslog can be configured to forward logging messages to Telegraf by configuring
+[remote logging](https://www.rsyslog.com/doc/v8-stable/configuration/actions.html#remote-machine).
+
+Most system are setup with a configuration split between `/etc/rsyslog.conf`
+and the files in the `/etc/rsyslog.d/` directory, it is recommended to add the
+new configuration into the config directory to simplify updates to the main
+config file.
+
+Add the following lines to `/etc/rsyslog.d/50-telegraf.conf` making
+adjustments to the target address as needed:
+```
+$ActionQueueType LinkedList # use asynchronous processing
+$ActionQueueFileName srvrfwd # set file name, also enables disk mode
+$ActionResumeRetryCount -1 # infinite retries on insert failure
+$ActionQueueSaveOnShutdown on # save in-memory data if rsyslog shuts down
+
+# forward over tcp with octet framing according to RFC 5425
+*.* @@(o)127.0.0.1:6514;RSYSLOG_SyslogProtocol23Format
+```
+
+To complete TLS setup please refer to [rsyslog docs](https://www.rsyslog.com/doc/v8-stable/tutorials/tls.html).

+# Swap Input Plugin
+
+The swap plugin collects system swap metrics.
+
+For a more information on what swap memory is, read [All about Linux swap space](https://www.linux.com/news/all-about-linux-swap-space).
+
+### Configuration:
+
+```toml
+# Read metrics about swap memory usage
+[[inputs.swap]]
+  # no configuration
+```
+
+### Metrics:
+
+- swap
+  - fields:
+    - free (int)
+    - total (int)
+    - used (int)
+    - used_percent (float)
+    - in (int)
+    - out (int)
+
+### Example Output:
+
+```
+swap total=20855394304i,used_percent=45.43883523785713,used=9476448256i,free=1715331072i 1511894782000000000
