Syslog 和 Loki 集成

[[inputs.syslog]]
  ## Protocol, address and port to host the syslog receiver.
  ## If no host is specified, then localhost is used.
  ## If no port is specified, 6514 is used (RFC5425#section-4.1).
  ##   ex: server = "tcp://localhost:6514"
  ##       server = "udp://:6514"
  ##       server = "unix:///var/run/telegraf-syslog.sock"
  ## When using tcp, consider using 'tcp4' or 'tcp6' to force the usage of IPv4
  ## or IPV6 respectively. There are cases, where when not specified, a system
  ## may force an IPv4 mapped IPv6 address.
  server = "tcp://127.0.0.1:6514"

  ## Permission for unix sockets (only available on unix sockets)
  ## This setting may not be respected by some platforms. To safely restrict
  ## permissions it is recommended to place the socket into a previously
  ## created directory with the desired permissions.
  ##   ex: socket_mode = "777"
  # socket_mode = ""

  ## Maximum number of concurrent connections (only available on stream sockets like TCP)
  ## Zero means unlimited.
  # max_connections = 0

  ## Read timeout (only available on stream sockets like TCP)
  ## Zero means unlimited.
  # read_timeout = "0s"

  ## Optional TLS configuration (only available on stream sockets like TCP)
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key  = "/etc/telegraf/key.pem"
  ## Enables client authentication if set.
  # tls_allowed_cacerts = ["/etc/telegraf/clientca.pem"]

  ## Maximum socket buffer size (in bytes when no unit specified)
  ## For stream sockets, once the buffer fills up, the sender will start
  ## backing up. For datagram sockets, once the buffer fills up, metrics will
  ## start dropping. Defaults to the OS default.
  # read_buffer_size = "64KiB"

  ## Period between keep alive probes (only applies to TCP sockets)
  ## Zero disables keep alive probes. Defaults to the OS configuration.
  # keep_alive_period = "5m"

  ## Content encoding for message payloads
  ## Can be set to "gzip" for compressed payloads or "identity" for no encoding.
  # content_encoding = "identity"

  ## Maximum size of decoded packet (in bytes when no unit specified)
  # max_decompression_size = "500MB"

  ## Framing technique used for messages transport
  ## Available settings are:
  ##   octet-counting  -- see RFC5425#section-4.3.1 and RFC6587#section-3.4.1
  ##   non-transparent -- see RFC6587#section-3.4.2
  # framing = "octet-counting"

  ## The trailer to be expected in case of non-transparent framing (default = "LF").
  ## Must be one of "LF", or "NUL".
  # trailer = "LF"

  ## Whether to parse in best effort mode or not (default = false).
  ## By default best effort parsing is off.
  # best_effort = false

  ## The RFC standard to use for message parsing
  ## By default RFC5424 is used. RFC3164 only supports UDP transport (no streaming support)
  ## Must be one of "RFC5424", or "RFC3164".
  # syslog_standard = "RFC5424"

  ## Character to prepend to SD-PARAMs (default = "_").
  ## A syslog message can contain multiple parameters and multiple identifiers within structured data section.
  ## Eg., [id1 name1="val1" name2="val2"][id2 name1="val1" nameA="valA"]
  ## For each combination a field is created.
  ## Its name is created concatenating identifier, sdparam_separator, and parameter name.
  # sdparam_separator = "_"

[[outputs.loki]]
  ## The domain of Loki
  domain = "https://loki.domain.tld"

  ## Endpoint to write api
  # endpoint = "/loki/api/v1/push"

  ## Connection timeout, defaults to "5s" if not set.
  # timeout = "5s"

  ## Basic auth credential
  # username = "loki"
  # password = "pass"

  ## Additional HTTP headers
  # http_headers = {"X-Scope-OrgID" = "1"}

  ## If the request must be gzip encoded
  # gzip_request = false

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"

  ## Sanitize Tag Names
  ## If true, all tag names will have invalid characters replaced with
  ## underscores that do not match the regex: ^[a-zA-Z_:][a-zA-Z0-9_:]*.
  # sanitize_label_names = false

  ## Metric Name Label
  ## Label to use for the metric name to when sending metrics. If set to an
  ## empty string, this will not add the label. This is NOT suggested as there
  ## is no way to differentiate between multiple metrics.
  # metric_name_label = "__name"
