输入和输出集成概述
Modbus 插件允许您使用各种通信方法从 Modbus 设备收集数据,从而增强您监控和控制工业流程的能力。
Graylog 插件允许您将 Telegraf 指标发送到 Graylog 服务器,利用 GELF 格式进行结构化日志记录。
集成详情
Modbus
Modbus 插件通过 Modbus TCP 或 Modbus RTU/ASCII 收集离散输入、线圈、输入寄存器和保持寄存器。
Graylog
Graylog 插件旨在用于使用 GELF(Graylog 扩展日志格式)格式将指标发送到 Graylog 实例。GELF 有助于标准化日志记录数据,使系统更容易发送和分析日志。该插件遵循 GELF 规范,该规范规定了有效负载中特定字段的要求。值得注意的是,时间戳必须采用 UNIX 格式,如果存在,插件会将时间戳原封不动地发送到 Graylog,不做任何更改。如果省略,它会自动生成时间戳。此外,任何规范中未明确定义的额外字段都将以一个下划线为前缀,这有助于保持数据井井有条并符合 GELF 的要求。这种能力对于实时监控应用程序和基础设施的用户尤其有价值,因为它允许跨多个系统进行无缝集成和提高可见性。

Graylog
[[outputs.graylog]]
## Endpoints for your graylog instances.
servers = ["udp://127.0.0.1:12201"]
## Connection timeout.
# timeout = "5s"
## The field to use as the GELF short_message, if unset the static string
## "telegraf" will be used.
## example: short_message_field = "message"
# short_message_field = ""
## According to GELF payload specification, additional fields names must be prefixed
## with an underscore. Previous versions did not prefix custom field 'name' with underscore.
## Set to true for backward compatibility.
# name_field_no_prefix = false
## Connection retry options
## Attempt to connect to the endpoints if the initial connection fails.
## If 'false', Telegraf will give up after 3 connection attempt and will
## exit with an error. If set to 'true', the plugin will retry to connect
## to the unconnected endpoints infinitely.
# connection_retry = false
## Time to wait between connection retry attempts.
# connection_retry_wait_time = "15s"
## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification
# insecure_skip_verify = false
输入和输出集成示例
Modbus
- 基本用法:要从单个设备读取数据,请使用设备名称和 IP 地址配置它,并指定从站 ID 和感兴趣的寄存器。
- 多个请求:您可以通过指定多个
[[inputs.modbus.request]]
部分,在单个配置中定义多个请求以从不同的 Modbus 从站设备获取数据。 - 数据处理:利用缩放功能将原始 Modbus 读数转换为有用的指标,并根据需要调整单位转换。
Graylog
-
增强云应用程序的日志管理:使用 Graylog Telegraf 插件聚合来自跨多个服务器云部署应用程序的日志。通过集成此插件,团队可以集中日志记录数据,从而更轻松地排除故障、监控应用程序性能并保持符合日志记录标准。
-
实时安全监控:利用 Graylog 插件收集安全相关的指标和日志并发送到 Graylog 服务器进行实时分析。这使安全团队能够通过关联来自基础设施内各种来源的日志,快速识别异常、跟踪潜在的漏洞并及时响应事件。
-
动态警报和通知系统:实施 Graylog 插件以增强基础设施中的警报机制。通过将指标发送到 Graylog,团队可以根据日志模式或意外行为设置动态警报,从而实现主动监控和快速事件响应策略。
-
跨平台日志整合:使用 Graylog 插件促进跨平台日志整合,跨越本地、混合和云等不同环境。通过以 GELF 格式标准化日志记录,组织可以确保一致的监控和故障排除实践,无论其服务托管在何处。
