=== Naming Conventions
|
|
|
|
When creating events, use the following conventions for field names and abbreviations.

|
|
==== Field Names
|
|
|
|
Use the following naming conventions for field names:
|
|
|
|
- All fields must be lower case.
|
|
- Use snake case (underscores) for combining words.
|
|
- Group related fields into subdocuments by using dot (.) notation. Groups typically have common prefixes. For example, if you have fields called `CPULoad` and `CPUSystem` in a service, you would convert
|
|
them into `cpu.load` and `cpu.system` in the event.
|
|
- Avoid repeating the namespace in field names. If a word or abbreviation appears in the namespace, it's not needed in the field name. For example, instead of `cpu.cpu_load`, use `cpu.load`.
|
|
- Use <<abbreviations,standardised names>> and avoid using abbreviations that aren't commonly known.
|
|
- Organise the documents from general to specific to allow for namespacing. The type, such as `.pct`, should always be last. For example, `system.core.user.pct`.
|
|
- If two fields are the same, but with different units, remove the less granular one. For example, include `timeout.sec`, but don't include `timeout.min`. If a less granular value is required, you can calculate it later.
|
|
- If a field name matches the namespace used for nested fields, add `.value` to the field name. For example, instead of:
|
|
+
|
|
[source,yaml]
|
|
----------
|
|
workers
|
|
workers.busy
|
|
workers.idle
|
|
----------
|
|
+
|
|
Use:
|
|
+
|
|
[source,yaml]
|
|
----------
|
|
workers.value
|
|
workers.busy
|
|
workers.idle
|
|
----------
|
|
- Do not use dots (.) in individual field names. Dots are reserved for grouping related fields into subdocuments.
|
|
- Use singular and plural names properly to reflect the field content. For example, use `requests_per_sec` rather than `request_per_sec`.
