node-logging

节点包,通过使用 pino弹性 APM

Setup

npm install @abeai/logging elastic-apm-node --save-exact
// Add those two line before requiring any other modules!
require('elastic-apm-node').start({
    active: process.env.ELASTIC_APM_ACTIVE === 'true',
});
require('@abeai/logging').configure({appName: 'loggingExampleApp'});

const express = require('express');
const logger = require('@abeai/logging').logger;
const loggingMiddleware = require('@abeai/logging').expressMiddleware;

const app = express();

// This middleware has to run before any logging occurs
app.use(loggingMiddleware.requestHandler());

app.get('/', (req, res) => {
    res.send('Hello World!');
});

// This error middleware has should be run first
app.use(loggingMiddleware.errorHandler());

app.listen(3000, () => logger.info(`Listening on port 3000`));

Express Middleware

const monitoringMiddleware = require('@abeai/logging').expressMiddleware

该中间件使用请求的标头属性填充记录器上下文,将上下文添加到 Elastic APM 代理,并记录基本的请求/响应信息。 中间件应尽早使用。

Function Signature:

function expressMiddleware(options)

可用的选项有:

  • requireRequestCorrelationId: Will log a warning if no correlation ID is found on the request. Though a correlation I is still generated on-the-line in this case. Default is true.
  • addResponseReferenceId: If true, the correlation ID will be added as the header Abe-AI-Reference-ID to the response. This is useful for consumers of our external APIs. Default is false.

Example:

app.use(monitoringMiddleware({requireRequestCorrelationId: false}));

Logging

Configuration

require('@abeai/logging').configure({appName: 'myAppName'});

Configuration Attributes:

  • appName: Is used to namespace log data which should be indexed. Is required.

Usage

const logger = require('@abeai/logging').logger

Message Logging

日志级别和pino的一样。 尽管函数签名有点不同:

  • logger.fatal
  • logger.error
  • logger.warning
  • logger.info
  • logger.debug
  • logger.trace

所有函数都可以只接受一条消息,或者一条带有数据的消息。 此外,fatalerrorwarning 支持将错误对象作为单个参数传递。

支持以下数据属性:

  • unindexed: Data which should be encoded as a JSON string to avoid indexing. It will be added to the top-level of the log message.
  • indexed: Data which should be encoded as JSON for indexing. It will be scoped by the logger name on the top-level of the log message avoid structure conflicts with other services.
  • err: Error object which should be serialized.

示例:

logger.info('log this');
logger.info('log with raw data', {unindexed: {aLotOfData: ...}});
logger.info('log with json data', {indexed: {dataWhichShouldBeIndexed: ...}});
logger.info('log with data', {unindexed: {aLotOfData: ...}, indexed: {dataWhichShouldBeIndexed: ...}});
logger.error(new Error('my error'));
logger.error('a separate error message', new Error('my error'));

Context Management

上下文支持以下属性:

  • correlationId: Correlation ID of current request chain. This attribute is always available and can't be set or merged.
  • channelType: Channel type related to current request chain. This attribute is optional.
  • channelId: Channel ID related to current request chain. This attribute is optional.
  • channelIdentityId: Channel Identity ID related to current request chain. This attribute is optional.
  • agentId: Agent ID related to current request chain. This attribute is optional.
  • agentName: Agent Name related to current request chain. This attribute is optional.
  • userId: User ID related to current request chain. This attribute is optional.
  • cuiUserId: CUI User ID related to current request chain. This attribute is optional.

可以使用以下函数管理当前上下文:

  • logger.setContext({channelType,channelId,channelIdentityId,agentId,userId,cuiUserId}): Overwites existing attributes.
  • logger.mergeContext({channelType,channelId,channelIdentityId,agentId,userId,cuiUserId}): Merges new attributes with existing attributes. New attributes win over existing attributes.
  • logger.context(): Returns all available context attributes as an object.

Context Propagation for Inter-Service Communication

记录器提供返回请求列表的函数 logger.requestHeaders()需要合并到对另一个 Abe AI 服务的请求的标头中的标头。

支持以下标头:

  • Abe-AI-Correlation-ID
  • Abe-AI-Channel-Type
  • Abe-AI-Channel-ID
  • Abe-AI-Channel-Identity-ID
  • Abe-AI-Agent-ID
  • Abe-AI-Agent-Name
  • Abe-AI-User-ID
  • Abe-AI-CUI-User-ID

示例:

rp({
    method: 'GET',
    uri: `${config.anotherAbeAiServiceUrl}/coolStuff`,
    headers: Object.assign({
        'My-Header': 'stuff',
    }, logger.contextRequestHeaders())
})
    .then((response) => {
        ...
    })
;

Deployment

包需要以下环境变量:

ELASTIC_APM_SERVICE_NAME=<service name>
ELASTIC_APM_SECRET_TOKEN=<token>
ELASTIC_APM_SERVER_URL=<server url>

node-logging

Node package to provide functionality around logging / monitoring of node services in Abe AI's ecosystem by using pino and Elastic APM.

Setup

npm install @abeai/logging elastic-apm-node --save-exact
// Add those two line before requiring any other modules!
require('elastic-apm-node').start({
    active: process.env.ELASTIC_APM_ACTIVE === 'true',
});
require('@abeai/logging').configure({appName: 'loggingExampleApp'});

const express = require('express');
const logger = require('@abeai/logging').logger;
const loggingMiddleware = require('@abeai/logging').expressMiddleware;

const app = express();

// This middleware has to run before any logging occurs
app.use(loggingMiddleware.requestHandler());

app.get('/', (req, res) => {
    res.send('Hello World!');
});

// This error middleware has should be run first
app.use(loggingMiddleware.errorHandler());

app.listen(3000, () => logger.info(`Listening on port 3000`));

Express Middleware

const monitoringMiddleware = require('@abeai/logging').expressMiddleware

This middleware populate the logger context with header attributes from the request, adds the context to the Elastic APM agent, and logs basic request/response information. The middleware should be used as early as possible.

Function Signature:

function expressMiddleware(options)

Available options are:

  • requireRequestCorrelationId: Will log a warning if no correlation ID is found on the request. Though a correlation I is still generated on-the-line in this case. Default is true.
  • addResponseReferenceId: If true, the correlation ID will be added as the header Abe-AI-Reference-ID to the response. This is useful for consumers of our external APIs. Default is false.

Example:

app.use(monitoringMiddleware({requireRequestCorrelationId: false}));

Logging

Configuration

require('@abeai/logging').configure({appName: 'myAppName'});

Configuration Attributes:

  • appName: Is used to namespace log data which should be indexed. Is required.

Usage

const logger = require('@abeai/logging').logger

Message Logging

The log levels are the same as pino's. Though the function signature is a bit different:

  • logger.fatal
  • logger.error
  • logger.warning
  • logger.info
  • logger.debug
  • logger.trace

All functions can take just just a message, or a message with data. Additionally fatal, error, and warning support passing in an error object as a single argument.

The following data attributes are supported:

  • unindexed: Data which should be encoded as a JSON string to avoid indexing. It will be added to the top-level of the log message.
  • indexed: Data which should be encoded as JSON for indexing. It will be scoped by the logger name on the top-level of the log message avoid structure conflicts with other services.
  • err: Error object which should be serialized.

Example:

logger.info('log this');
logger.info('log with raw data', {unindexed: {aLotOfData: ...}});
logger.info('log with json data', {indexed: {dataWhichShouldBeIndexed: ...}});
logger.info('log with data', {unindexed: {aLotOfData: ...}, indexed: {dataWhichShouldBeIndexed: ...}});
logger.error(new Error('my error'));
logger.error('a separate error message', new Error('my error'));

Context Management

The context supports the following attributes:

  • correlationId: Correlation ID of current request chain. This attribute is always available and can't be set or merged.
  • channelType: Channel type related to current request chain. This attribute is optional.
  • channelId: Channel ID related to current request chain. This attribute is optional.
  • channelIdentityId: Channel Identity ID related to current request chain. This attribute is optional.
  • agentId: Agent ID related to current request chain. This attribute is optional.
  • agentName: Agent Name related to current request chain. This attribute is optional.
  • userId: User ID related to current request chain. This attribute is optional.
  • cuiUserId: CUI User ID related to current request chain. This attribute is optional.

The current context can be managed with the following functions:

  • logger.setContext({channelType,channelId,channelIdentityId,agentId,userId,cuiUserId}): Overwites existing attributes.
  • logger.mergeContext({channelType,channelId,channelIdentityId,agentId,userId,cuiUserId}): Merges new attributes with existing attributes. New attributes win over existing attributes.
  • logger.context(): Returns all available context attributes as an object.

Context Propagation for Inter-Service Communication

The logger provides the function logger.requestHeaders() which returns a list of requests headers which needs to be merged into the headers of a requests to another Abe AI service.

The following headers are supported:

  • Abe-AI-Correlation-ID
  • Abe-AI-Channel-Type
  • Abe-AI-Channel-ID
  • Abe-AI-Channel-Identity-ID
  • Abe-AI-Agent-ID
  • Abe-AI-Agent-Name
  • Abe-AI-User-ID
  • Abe-AI-CUI-User-ID

Example:

rp({
    method: 'GET',
    uri: `${config.anotherAbeAiServiceUrl}/coolStuff`,
    headers: Object.assign({
        'My-Header': 'stuff',
    }, logger.contextRequestHeaders())
})
    .then((response) => {
        ...
    })
;
