| file_path* | strings | | File or directory paths to tail for logs. |
| exclude_file_path | strings | "" | File or directory paths to exclude. |
| log_type | string | "file" | A friendly name that will be added to each log entry as an attribute. |
| parse_format | enum | none | Method to use when parsing. Valid values are none, json, and regex. When regex is selected, 'Regex Pattern' must be set. |
| regex_pattern | string | | The regex pattern that is used when parsing log entries. |
| multiline_line_start_pattern | string | | Regex pattern that matches the beginning of a log entry for handling multiline logs. |
| multiline_line_end_pattern | string | | Regex pattern that matches the end of a log entry, useful for terminating parsing of multiline logs. |
| parse_timestamp | bool | false | Whether to parse the timestamp from the log entry. |
| timestamp_field | string | timestamp | The field containing the timestamp in the log entry. |
| parse_timestamp_format | enum | ISO8601 | The format of the timestamp in the log entry. Choose a common format, or specify a custom format. Options include "ISO8601", "RFC3339", "Epoch", and "Manual". |
| epoch_timestamp_format | enum | s | The layout of the epoch-based timestamp. It's required when parse_timestamp_format is set to "Epoch". Options include "s", "ms", "us", "ns", "s.ms", "s.us", "s.ns". |
| manual_timestamp_format | string | '%Y-%m-%dT%H:%M:%S.%f%z' | The strptime layout of the timestamp. It's used when parse_timestamp_format is set to "Manual". |
| timezone | timezone | UTC | The timezone to use if the Timestamp Format doesn't include a timezone. Otherwise, the timezone in the Timestamp Format will be respected. NOTE: This is also required to parse timezone abbreviations due to their ambiguity. |
| parse_severity | bool | false | Whether to parse severity from the log entry. |
| severity_field | string | severity | The field containing the severity in the log entry. |
| encoding | enum | utf-8 | The encoding of the file being read. Valid values are nop, utf-8, utf-16le, utf-16be, ascii, and big5. |
| include_file_name_attribute | bool | true | Whether to add the file name as the attribute log.file.name. |
| include_file_path_attribute | bool | false | Whether to add the file path as the attribute log.file.path. |
| include_file_name_resolved | bool | false | Whether to add the file name after symlinks resolution as the attribute log.file.name_resolved. |
| include_file_path_resolved | bool | false | Whether to add the file path after symlinks resolution as the attribute log.file.path_resolved. |
| delete_after_read | bool | false | Whether to delete the file(s) after reading. Only valid in combination start_at: beginning. |
| offset_storage_dir | string | $OIQ_OTEL_COLLECTOR_HOME/storage | The directory where the offset storage file will be created. It is okay if multiple receivers use the same directory. By default, the observIQ Distro for OpenTelemetry Collector sets $OIQ_OTEL_COLLECTOR_HOME in its runtime. |
| poll_interval | int | 200 | The duration of time in milliseconds between filesystem polls. |
| max_concurrent_files | int | 1024 | The maximum number of log files from which logs will be read concurrently. If the number of files matched exceeds this number, then files will be processed in batches. |
| parse_to | string | body | The field that the log will be parsed to. Some exporters handle logs favorably when parsed to attributes over body and vice versa. |
| start_at | enum | end | Start reading the file from the 'beginning' or 'end'. |
