输入和输出集成概述
Docker 输入插件允许您使用 Docker Engine API 从 Docker 容器中收集指标,从而增强容器化应用程序的可见性和监控。
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
Docker
Telegraf 的 Docker 输入插件从 Docker Engine API 收集有价值的指标,从而提供对正在运行的容器的洞察。此插件利用官方 Docker 客户端与 Engine API 交互,允许用户监控各种容器状态、资源分配和性能指标。通过按名称和状态过滤容器的选项,以及可自定义的标签,此插件支持在各种环境中监控容器化应用程序的灵活性,无论是在本地系统上还是在 Kubernetes 等编排平台中。此外,它通过要求访问 Docker 守护程序的权限来解决安全问题,并强调在容器化环境中部署时的正确配置。
Graylog
Graylog 插件旨在用于使用 GELF (Graylog Extended Log Format) 格式将指标发送到 Graylog 实例。GELF 有助于标准化日志记录数据,使系统更轻松地发送和分析日志。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,时间戳必须为 UNIX 格式,如果存在,插件会将时间戳原样发送到 Graylog,而不会进行更改。如果省略,它会自动生成时间戳。此外,任何规范未明确定义的额外字段都将以_为前缀,这有助于保持数据组织性并符合 GELF 的要求。此功能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并提高可见性。
配置
Docker
[[inputs.docker]]
## Docker Endpoint
## To use TCP, set endpoint = "tcp://[ip]:[port]"
## To use environment variables (ie, docker-machine), set endpoint = "ENV"
endpoint = "unix:///var/run/docker.sock"
## Set to true to collect Swarm metrics(desired_replicas, running_replicas)
## Note: configure this in one of the manager nodes in a Swarm cluster.
## configuring in multiple Swarm managers results in duplication of metrics.
gather_services = false
## Only collect metrics for these containers. Values will be appended to
## container_name_include.
## Deprecated (1.4.0), use container_name_include
container_names = []
## Set the source tag for the metrics to the container ID hostname, eg first 12 chars
source_tag = false
## Containers to include and exclude. Collect all if empty. Globs accepted.
container_name_include = []
container_name_exclude = []
## Container states to include and exclude. Globs accepted.
## When empty only containers in the "running" state will be captured.
# container_state_include = []
# container_state_exclude = []
## Objects to include for disk usage query
## Allowed values are "container", "image", "volume"
## When empty disk usage is excluded
storage_objects = []
## Timeout for docker list, info, and stats commands
timeout = "5s"
## Whether to report for each container per-device blkio (8:0, 8:1...),
## network (eth0, eth1, ...) and cpu (cpu0, cpu1, ...) stats or not.
## Usage of this setting is discouraged since it will be deprecated in favor of 'perdevice_include'.
## Default value is 'true' for backwards compatibility, please set it to 'false' so that 'perdevice_include' setting
## is honored.
perdevice = true
## Specifies for which classes a per-device metric should be issued
## Possible values are 'cpu' (cpu0, cpu1, ...), 'blkio' (8:0, 8:1, ...) and 'network' (eth0, eth1, ...)
## Please note that this setting has no effect if 'perdevice' is set to 'true'
# perdevice_include = ["cpu"]
## Whether to report for each container total blkio and network stats or not.
## Usage of this setting is discouraged since it will be deprecated in favor of 'total_include'.
## Default value is 'false' for backwards compatibility, please set it to 'true' so that 'total_include' setting
## is honored.
total = false
## Specifies for which classes a total metric should be issued. Total is an aggregated of the 'perdevice' values.
## Possible values are 'cpu', 'blkio' and 'network'
## Total 'cpu' is reported directly by Docker daemon, and 'network' and 'blkio' totals are aggregated by this plugin.
## Please note that this setting has no effect if 'total' is set to 'false'
# total_include = ["cpu", "blkio", "network"]
## docker labels to include and exclude as tags. Globs accepted.
## Note that an empty array for both will include all labels as tags
docker_label_include = []
docker_label_exclude = []
## Which environment variables should we use as a tag
tag_env = ["JAVA_HOME", "HEAP_SIZE"]
## 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
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
