Alert
An alert is the outcome of an alerting rule in Prometheus that is actively firing. 
Alerts are sent from Prometheus to the Alertmanager.

激活的报警规则产生告警， 发送给 Alertmanager



Alertmanager
The Alertmanager takes in alerts, aggregates them into groups, de-duplicates, applies silences, throttles, 
and then sends out notifications to email, Pagerduty, Slack etc.

接收告警，并把它们聚合成组、去重据、应用静默和节流，然后发送通知到邮件、Pageduty或者Slack等系统


Bridge
A bridge is a component that takes samples from a client library 
and exposes them to a non-Prometheus monitoring system. 
For example, the Python, Go, and Java clients can export metrics to Graphite.

网桥 从客户端库采样，然后将其暴露给非Prometheus监控系统。例如：Java客户端可以将指标数据导出到Graphite



Client library
A client library is a library in some language (e.g. Go, Java, Python, Ruby) 
that makes it easy to directly instrument your code, 
write custom collectors to pull metrics from other systems and expose the metrics to Prometheus.

客户端库， 写代码采集指标 暴露给 Prometheus



Collector
A collector is a part of an exporter that represents a set of metrics. 
It may be a single metric if it is part of direct instrumentation, 
or many metrics if it is pulling metrics from another system.

收集器 指标导出器的一部分。它可以是单个指标，也可以是从另一个系统提取的多个指标。



Direct instrumentation
Direct instrumentation is instrumentation added inline as part the source code of a program.

编码采集指标 


Endpoint
A source of metrics that can be scraped, usually corresponding to a single process.
端点 ， 可抓取的指标源  通常为一个进程

Exporter
An exporter is a binary that exposes Prometheus metrics, 
commonly by converting metrics that are exposed in a non-Prometheus format into a format Prometheus supports.

转换指标 转成 Prometheus 支持的格式

Instance
An instance is a label that uniquely identifies a target in a job.
实例 作业 目标

Job
A collection of targets with the same purpose, for example monitoring a group of like processes replicated for scalability or reliability, is called a job.



Notification
A notification represents a group of one of more alerts, and is sent by the Alertmanager to email, Pagerduty, Slack etc.
通知是一组告警

Promdash
Promdash was a native dashboard builder for Prometheus. It has been deprecated and replaced by Grafana.
Prometheus的内置面板 ， 已废弃 ，建议使用 Grafana


Prometheus
Prometheus usually refers to the core binary of the Prometheus system. 
It may also refer to the Prometheus monitoring system as a whole.

PromQL
PromQL is the Prometheus Query Language. 
It allows for a wide range of operations including aggregation, slicing and dicing, prediction and joins.

查询语言
聚合 分片 切割 预测 连接 操作

Pushgateway
The Pushgateway persists the most recent push of metrics from batch jobs. 
This allows Prometheus to scrape their metrics after they have terminated.

Remote Read
Remote read is a Prometheus feature that allows transparent reading of time series from other systems (such as long term storage) as part of queries.

Remote Read Adapter
Not all systems directly support remote read. A remote read adapter sits between Prometheus and another system, converting time series requests and responses between them.

Remote Read Endpoint
A remote read endpoint is what Prometheus talks to when doing a remote read.

Remote Write
Remote write is a Prometheus feature that allows sending ingested samples on the fly to other systems, such as long term storage.

Remote Write Adapter
Not all systems directly support remote write. A remote write adapter sits between Prometheus and another system, converting the samples in the remote write into a format the other system can understand.

Remote Write Endpoint
A remote write endpoint is what Prometheus talks to when doing a remote write.

Sample
A sample is a single value at a point in time in a time series.

In Prometheus, each sample consists of a float64 value and a millisecond-precision timestamp.

单一的值   64位浮点数 毫秒时间戳

Silence
A silence in the Alertmanager prevents alerts, with labels matching the silence, from being included in notifications.
阻止告警通知

Target
A target is the definition of an object to scrape. For example, what labels to apply, any authentication required to connect, or other information that defines how the scrape will occur.
