Configuration

custom-rules

(string) base64 encoded rules to be loaded by prometheus.yml (custom.rules file)

evaluation-interval

(string) Default evaluation interval

15s

external_url

(string) The URL under which Prometheus is externally reachable (for example, if Prometheus is served via a reverse proxy). Used for generating relative and absolute links back to Prometheus itself. If the URL has a path portion, it will be used to prefix all HTTP endpoints served by Prometheus. If omitted, relevant URL components will be derived automatically. It's templatized to accept the following vars: {private_address}, {public_address}, {port}, thus you can use e.g.: juju set prometheus external_url="http://{private_address}:{port}/"

install_keys

(string) YAML list of GPG keys for installation sources, as a string. For apt repository URLs, use the public key ID used to verify package signatures. For other sources such as PPA, use empty string. This list must have the same number of elements as install_sources, even if the key items are all empty string. An example to go with the above for install_sources: install_keys: | - "ABC" - ""

install_sources

(string) YAML list of additional installation sources, as a string. The number of install_sources must match the number of install_keys. For example: install_sources: | - ppa:project1/ppa - ppa:project2/ppa

[ "ppa:canonical-bootstack/prometheus" ]

monitor-name

(string) Prometheus monitor name, will default <service_name>-monitor if not set

nagios_context

(string) A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-myservice-0 If you're running multiple environments with the same services in them this allows you to differentiate between them.

juju

nagios_servicegroups

(string) Comma separated list of nagios servicegroups for the graphite check

juju

scrape-interval

(string) Interval at which to scrape targets

15s

static-targets
