Prometheus的基本指标类型

1、 Counter：只增不减的累加指标

Counter就是一个计数器，表示一种累积型指标，该指标只能单调递增或在重新启动时重置为零，例如，您可以使用计数器来表示所服务的请求数，已完成的任务或错误。

2、 Gauge：可增可减的测量指标

Gauge是最简单的度量类型，只有一个简单的返回值，可增可减，也可以set为指定的值。所以Gauge通常用于反映当前状态，比如当前温度或当前内存使用情况；当然也可以用于“可增加可减少”的计数指标。

3、Histogram：自带buckets区间用于统计分布的直方图

Histogram主要用于在设定的分布范围内(Buckets)记录大小或者次数。

例如http请求响应时间：0-100ms、100-200ms、200-300ms、>300ms 的分布情况，Histogram会自动创建3个指标，分别为：

事件发送的总次数：比如当前一共发生了2次http请求 所有事件产生值的大小的总和：比如发生的2次http请求总的响应时间为150ms 事件产生的值分布在bucket中的次数：比如响应时间0-100ms的请求1次，100-200ms的请求1次，其他的0次 4、Summary：数据分布统计图

Summary和Histogram类似，都可以统计事件发生的次数或者大小，以及其分布情况。

Summary和Histogram都提供了对于事件的计数_count以及值的汇总_sum，因此使用_count,和_sum时间序列可以计算出相同的内容。

同时Summary和Histogram都可以计算和统计样本的分布情况，比如中位数，n分位数等等。不同在于Histogram可以通过histogram_quantile函数在服务器端计算分位数。 而Sumamry的分位数则是直接在客户端进行定义。因此对于分位数的计算。 Summary在通过PromQL进行查询时有更好的性能表现，而Histogram则会消耗更多的资源。相对的对于客户端而言Histogram消耗的资源更少。

Mirth Channel Exporter

Export Mirth Connect channel statistics to Prometheus.

Metrics are retrieved using the Mirth Connect REST API. This has only been tested with Mirth Connect 3.7.1, and it should work with version after 3.7.1.

To run it:

go build
./mirth_channel_exporter [flags]

Exported Metrics

Metric	Description	Labels
mirth_up	Was the last Mirth CLI query successful
mirth_messages_received_total	How many messages have been received	channel
mirth_messages_filtered_total	How many messages have been filtered	channel
mirth_messages_queued	How many messages are currently queued	channel
mirth_messages_sent_total	How many messages have been sent	channel
mirth_messages_errored_total	How many messages have errored	channel

Flags

./mirth_channel_exporter --help

Flag	Description	Default
log.level	Logging level	info
web.listen-address	Address to listen on for telemetry	:9141
web.telemetry-path	Path under which to expose metrics	/metrics
config.file-path	Optional environment file path	None

Env Variables

Use a .env file in the local folder, /etc/sysconfig/mirth_channel_exporter, or use the --config.file-path command line flag to provide a path to your environment file
