options:
tags:
type: string
default: ""
description: |
Comma separated list of global tags.
ie, 'dc=us-east-1,rack=1a' will tag all metrics with dc=us-east-1 and rack=1a
interval:
type: string
default: "10s"
description: "Default data collection interval for all plugins"
round_interval:
type: boolean
default: true
description: |
Rounds collection interval to 'interval'
ie, if interval="10s" then always collect on :00, :10, :20, etc.
flush_interval:
type: string
default: "10s"
description: |
Default data flushing interval for all outputs. You should not set this below
interval. Maximum flush_interval will be flush_interval + flush_jitter
flush_jitter:
type: string
default: "0s"
description: |
Jitter the flush interval by a random amount. This is primarily to avoid
large write spikes for users running a large number of telegraf instances.
ie, a jitter of 5s and interval 10s means flushes will happen every 10-15s
collection_jitter:
type: string
default: "0s"
description: |
Collection jitter is used to jitter the collection by a random amount.
Each plugin will sleep for a random time within jitter before collecting.
This can be used to avoid many plugins querying things like sysfs at the
same time, which can have a measurable effect on the system.
metric_buffer_limit:
type: int
default: 10000
description: |
Telegraf will cache metric_buffer_limit metrics for each output, and will
flush this buffer on a successful write.
debug:
type: boolean
default: false
description: "Run telegraf in debug mode"
quiet:
type: boolean
default: false
description: "Run telegraf in quiet mode"
hostname:
type: string
default: "{model}:{unit}"
description: |
Override default hostname. {model} is replaced with the Juju
model name and {unit} is replaced with the sanitized unit name
(eg. service_name-0). {uuid} is replaced by the model UUID, for
sites without unique model names. {host} is replaced by the
machine hostname
prometheus_output_port:
type: string
default: "9103"
description: |
If set prometheus output plugin will be configured to listen on the provided port.
If set to string "default" the charm will use default port (9103)
inputs_config:
type: string
default: ""
description: "[inputs.xxx] sections as a string, this override default input plugins."
outputs_config:
type: string
default: ""
description: "[outputs.xxx] sections as a string"
install_sources:
# description and type comes from the apt layer.
default: |
- ppa:telegraf-devs/ppa
install_keys:
# description and type comes from the apt layer.
default: |
- null
extra_options:
default: ""
type: string
description: |
YAML with extra options for out|inputs managed by relations or in the default config.
example:
inputs:
cpu:
percpu: false
fielddrop: ["time_*"]
disk:
mount_points: ["/"]
ignore_fs: ["tmpfs", "devtmpfs"]
elasticsearch:
local: false
cluster_health: true
postgresql:
databases: ["foo", "bar"]
tagpass:
db: ["template", "postgres"]
outputs:
influxdb:
precision: ms
extra_plugins:
default: ""
type: string
description: |
Extra plugins, manually configured. This is expected to be a string
and will be saved "as is" in /etc/telegraf/telegraf.d/extra_plugins.conf
