Overview ¶
Package module contains Metricbeat modules and their MetricSet implementations.
= Naming conventions
For the key names, metricbeat follows the naming conventions below:
* all field keys lower case * snake case for combining words * Group related fields in sub documents, which means using the . notation. Groups are mostly described by common prefixes. * Prevent namespace duplication. If connections appears in the namespace, it's not needed in the sub document * Do not use complex abbreviations. A list of standardised abbreviations can be found below. * Organise the documents from the general to the details, which allows namespacing. The type should always be last, like .pct. * If two fields are the same but with different units, remove the less granular one * In case the value correlates with the name of a nested document, use value inside the document * Do not use . in the names * Use singular and plural properly for the fields. Example: sec_per_request vs open_requests * Use singular names for metricsets. It easier to read the event created: system.process.load = 0.3
The goal is to have a similar experience across all metrics.
= Abbrevations
List of standardised words and units across all metricsets. On the left are the ones to be used, on the right the options seen in metricsets.
* avg: average * connection: conn * count: * day: days, d * max: maximumg * min: minimum * pct: precentage * request: req * sec: seconds, second, s * ms: millisecond, millis * mb: megabytes * msg: message
