File

The file scraper is used to create config items from files in a local folder (or git). This can be used to track changes in files like /etc/hosts or /etc/passwd, or for service metadata stored in git.

See Kubernetes Files for scraping files inside running kubernetes pods.

Mapping

Custom scrapers require you to define the id and type for each scraped item. For example, when you scrape a file containing a JSON array, where each array element represents a config item, you must specify the id and type for those items. You can achieve this by using mappings in your custom scraper configuration.

Field	Description	Scheme
id*	A static value or JSONPath expression to use as the ID for the resource.	string or JSONPath
name*	A static value or JSONPath expression to use as the name for the resource.	string or JSONPath
type*	A static value or JSONPath expression to use as the type for the resource.	string or JSONPath
class	A static value or JSONPath expression to use as the class for the resource.	string or JSONPath
createFields	A list of JSONPath expressions used to identify the created time of the config. If multiple fields are specified, the first non-empty value will be used.	[]jsonpath
deleteFields	A list of JSONPath expressions used to identify the deleted time of the config. If multiple fields are specified, the first non-empty value will be used.	[]jsonpath
description	A static value or JSONPath expression to use as the description for the resource.	string or JSONPath
format	Format of config item, defaults to JSON, available options are JSON, properties. See Formats	string
health	A static value or JSONPath expression to use as the health of the config item.	string or JSONPath
items	A JSONPath expression to use to extract individual items from the resource. Items are extracted first and then the ID, Name, Type and transformations are applied for each item.	JSONPath
status	A static value or JSONPath expression to use as the status of the config item.	string or JSONPath
timestampFormat	A Go time format string used to parse timestamps in createFields and deleteFields. (Default: RFC3339)	string

Formats

JSON

The scraper stores config items as jsonb fields in PostgreSQL.

Resource providers typically return the JSON used. e.g. kubectl get -o json or aws --output=json.

When you display the config, the UI automatically converts the JSON data to YAML for improved readability.

XML / Properties

The scraper stores non-JSON files as JSON using:

{ 'format': 'xml', 'content': '<root>..</root>' }

You can still access non-JSON content in scripts using config.content.

The UI formats and renders XML appropriately.

Full Scraper Output

When you enable full: true, custom scrapers can return complex objects containing config data, changes, access logs, and external entities.

See the Custom Scraper page for the full output schema, shorthand keys, external entity schemas, and alias resolution.
