# Parser Processor Plugin
This plugin parses defined fields or tags containing the specified data format
and creates new metrics based on the contents of the field or tag.
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.
[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins
## Configuration
```toml @sample.conf
# Parse a value in a specified field(s)/tag(s) and add the result in a new metric
[[processors.parser]]
## The name of the fields whose value will be parsed.
parse_fields = ["message"]
## Fields to base64 decode.
## These fields do not need to be specified in parse_fields.
## Fields specified here will have base64 decode applied to them.
# parse_fields_base64 = []
## The name of the tags whose value will be parsed.
# parse_tags = []
## If true, incoming metrics are not emitted.
# drop_original = false
## Merge Behavior
## Only has effect when drop_original is set to false. Possible options
## include:
## * override: emitted metrics are merged by overriding the original metric
## using the newly parsed metrics, but retains the original metric
## timestamp.
## * override-with-timestamp: the same as "override", but the timestamp is
## set based on the new metrics if present.
# merge = ""
## The dataformat to be read from files
## Each data format has its 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"
```
## Example
```toml
[[processors.parser]]
parse_fields = ["message"]
merge = "override"
data_format = "logfmt"
```
