Paulgear Telegraf

collection_jitter | string

Default: 0s

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.

cpu_idle | int

Default: 10

Percent of idle CPU at which to generate a Prometheus alert. Default 10%, i.e. alert if the CPU has less than 10% CPU running idle therefore 90% used by us+sy+wa+st.

debug | boolean

Run telegraf in debug mode

extra_options | string

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_packages | string

Space separated list of extra deb packages to install.

extra_plugins | string

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

flush_interval | string

Default: 10s

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 | string

Default: 0s

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

hostname | string

Default: {model}:{unit}

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

inputs_config | string

[inputs.xxx] sections as a string, this override default input plugins.

install_keys | string

Default: - null

List of signing keys for install_sources package sources, per charmhelpers standard format (a yaml list of strings encoded as a string). The keys should be the full ASCII armoured GPG public keys. While GPG key ids are also supported and looked up on a keyserver, operators should be aware that this mechanism is insecure. null can be used if a standard package signing key is used that will already be installed on the machine, and for PPA sources where the package signing key is securely retrieved from Launchpad.

install_sources | string

Default: - ppa:telegraf-devs/ppa

List of extra apt sources, per charm-helpers standard format (a yaml list of strings encoded as a string). Each source may be either a line that can be added directly to sources.list(5), or in the form ppa:<user>/<ppa-name> for adding Personal Package Archives, or a distribution component to enable.

interval | string

Default: 10s

Default data collection interval for all plugins

lead_time | string

Default: 14d

Time period to use when alerting on predictive Prometheus rules, e.g a disk might run low on space in $lead_time, based on the previous usage over lead_time. Default 14d, i.e. based on the previous 14 days, alert if we have 14 days disk left. String, e.g. 14d, 4w.

metric_buffer_limit | int

Default: 10000

Telegraf will cache metric_buffer_limit metrics for each output, and will flush this buffer on a successful write.

outputs_config | string

[outputs.xxx] sections as a string

package_status | string

Default: install

The status of service-affecting packages will be set to this value in the dpkg database. Valid values are "install" and "hold".

prometheus_context | string

Default: juju

A string that will be used to identify this site in the 'cloud_name' label in Prometheus. If you're running multiple environments with the same services in them this allows you to differentiate between them.

prometheus_output_port | string

Default: 9103

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)

promreg_authtoken | string

The Prometheus Registration authtoken.

promreg_url | string

The http(s) url and port where the Prometheus Registration service is listening.

quiet | boolean

Run telegraf in quiet mode

round_interval | boolean

Default: True

Rounds collection interval to 'interval' ie, if interval="10s" then always collect on :00, :10, :20, etc.

tags | string

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

wait_time | string

Default: 5m

When exporting Prometheus alerting rules, how long a condition should be true before firing an alert. String, e.g. 5m, 1h, etc.
