Ansible role that installs and configures Prometheus: a multi-dimensional, non-distributed time-series database and monitoring/alerting toolkit.

Supported Platforms:

* Debian
* Redhat(CentOS/Fedora)
* Ubuntu

Requirements

Requires the unzip/gtar utility to be installed on the target host. See ansible unarchive module notes for details.

Role Variables

Variables are available and organized according to the following software & machine provisioning stages:

• install
• config
• launch
• uninstall

Install

prometheus and its associated alertmanager can be installed using compressed archives (.tar, .zip), downloaded and extracted from various sources.

The following variables can be customized to control various aspects of this installation process, ranging from software version and source location of binaries to the installation directory where they are stored:

managed_services: <list-of-services (prometheus | alertmanager)> (default: ['prometheus'])

• list of Prometheus toolkit services to manage via this role

prometheus_user: <service-user-name> (default: prometheus)

alertmgr_archive_url: <path-or-url-to-archive> (default: see defaults/main.yml)

• address of a compressed tar or zip archive containing alertmanager binaries. This method technically supports installation of any available version of alertmanager. Links to official versions can be found here.

alertmgr_archive_checksum: <path-or-url-to-checksum> (default: see defaults/main.yml)

• address of a checksum file for verifying the data integrity of the specified alertmanager archive. While recommended and generally considered a best practice, specifying a checksum is not required and can be disabled by providing an empty string ('') for its value.

Config

Using this role, configuration of a prometheus installation is organized according to the following components:

• prometheus service configuration (prometheus.yml)
• file service discovery (file_sd - *.[json|yml])
• recording and alerting rules (rule_files - *.[json|yml])
• alertmanager service configuration (alertmanager.yml)
• alertmanager template files (*.tmpl)

Each configuration can be expressed within the following variables in order to customize the contents and settings of the designated configuration files to be rendered:

config_dir: </path/to/configuration/dir> (default: {{ install_dir }})

• path on target host where prometheus config files should be rendered

data_dir: </path/to/data/dir> (default: /var/data/prometheus)

• path on target host where alertmanager config files should be rendered

alertmgr_datadir: </path/to/data/dir> (default: /var/data/alertmanager)

• path on target host where alertmanager stores data

Prometheus Service configuration

Prometheus service configuration can be expressed within the hash, prometheus_config, which contains a set of key-value pairs representing one of a set of sections indicating various scrape targets (sources from which to collect metrics), service discovery mechanisms, recording/alert rulesets and configurations for interfacing with remote read/write systems utlized by the Prometheus service.

The values of these keys are generally dicts or lists of dicts themselves containing a set of key-value pairs representing associated specifications/settings (e.g. the scrape interval or frequency at which to scrape targets for metrics globally) for each section. The following provides an overview and example configurations of each for reference.

:global

[prometheus_config:] global: <key: value,...> (default: see defaults/main.yml)

• specifies parameters that are valid and serve as defaults in all other configuration contexts. See here for more details.

Example

 prometheus_config:
   global:
     # How frequently to scrape targets by default.
     scrape_interval: 15s
     # How long until a scrape request times out.
     scrape_timeout: 30s
     # How frequently to evaluate rules.
     evaluation_interval: 30s
     # The labels to add to any time series or alerts when communicating with
     # external systems (federation, remote storage, Alertmanager).
     external_labels:
       monitor: example
       foo: bar

:scrape_configs

[prometheus_config:] scrape_configs: <list-of-dicts> (default: see defaults/main.yml)

• specifies a set of targets and parameters describing how to scrape them organized into jobs

Targets may be statically configured or dynamically discovered using one of the supported service discovery mechanisms. See here for more details and here for a list of supported service discovery methods.

Example

 prometheus_config:
   scrape_configs:
     - job_name: static-example
       static_configs:
       - targets: ['localhost:9090', 'localhost:9191']
         labels:
           example: label
     - job_name: kubernetes-example
       kubernetes_sd_configs:
       - role: endpoints
         api_server: 'https://localhost:1234'
         namespaces:
           names:
             - default

:rule_files

[prometheus_config:] rule_files: <list> (default: see defaults/main.yml)

• specifies a list of globs indicating file names and paths

Rules and alerts are read from all matching files. Rules fall into one of two categories: recording and alerting. See here for details surrounding recording rules and here for details surrounding alerting rules.

Example

 prometheus_config:
   rule_files:
   - "example.yml"
   - "example_rules/*"

:remote_read

[prometheus_config:] remote_read: <list-of-dicts> (default: see defaults/main.yml)

• specifies settings related to the remote read feature

See here for more details. For a list of available remote read/storage plugins/integrations, reference this link.

Example

 prometheus_config:
   remote_read:
   - url: http://remote1/read
     read_recent: true
     name: default
   - url: http://remote2/read
     read_recent: false
     name: read_special
     required_matchers:
       job: special
     tls_config:
       cert_file: valid_cert_file
       key_file: valid_key_file

:remote_write

[prometheus_config:] remote_write: <list-of-dicts> (default: see defaults/main.yml)

• specifies settings related to the remote write feature

See here for more details. For a list of available remote write/storage plugins/integrations, reference this link.

Example

 prometheus_config:
   remote_write:
   - name: drop_expensive
     url: http://remote1/push
     write_relabel_configs:
     - source_labels: [__name__]
       regex: expensive.*
       action: drop
   - name: rw_tls
     url: http://remote2/push
     tls_config:
       cert_file: valid_cert_file
       key_file: valid_key_file

:alerting

[prometheus_config:] alerting: <key: value,...> (default: see defaults/main.yml)

• specifies settings related to the Alertmanager in addition to Alertmanager instances the Prometheus server sends alerts to

This section provides the parameters to configure how to communicate with these Alertmanagers. Alertmanagers may be statically configured via the static configs parameter or dynamically discovered using one of the supported service discovery mechanims. See here for more details.

Example

 prometheus_config:
   alerting:
     alertmanagers:
     - scheme: https
       static_configs:
     - targets:
       - "1.2.3.4:9093"
       - "1.2.3.5:9093"

File service discovery

File-based service discovery provides a more generic way to configure static targets and serves as an interface to plug in custom service discovery mechanisms. It reads a set of files containing a list of zero or more <static_config>s. Changes to all defined files are detected via disk watches and applied immediately. Files may be provided in YAML or JSON format. Only changes resulting in well-formed target groups are applied. See here for more details.

prometheus_file_sd: <list-of-dicts> (default: [])

• specifies prometheus file_sd configurations to render

Using this role, file-based service discovery configuration settings can be expressed within the hash, prometheus_file_sd, which contains a list of dicts encapsulating the path, name and configuration contents of a yaml or json file set to be loaded by prometheus for file-based discovery.

[prometheus_file_sd : <entry>:] name: <string> (default: NONE - required)

• name of file_sd file to render

[prometheus_file_sd : <entry>:] path: <string> (default: {{ install_dir }}/file_sd)

• path of file_sd file to render

[prometheus_file_sd : <entry>:] config: <list-of-dicts> (default: NONE - required)

• list of dictionaries representing settings indicating set of static targets to specify in file_sd file

Example

 prometheus_file_sd:
 - name: example-file.slow.json
   config:
   - targets: ["host1:1234"]
     labels:
       test-label: example-slow-file-sd
 - name: file.yml
   path: /etc/prometheus/file_sd
   config:
   - targets: ["host2:1234"]

NB: An associated file_sd service discovery scrape_config is expected to be included within the prometheus.yml file for successful load.

Rule files

Prometheus supports two types of rules which may be configured and then evaluated at regular intervals: recording rules and alerting rules. Recording rules allow you to precompute frequently needed or computationally expensive expressions and save their result as a new set of time series.. Alerting rules allow you to define alert conditions based on Prometheus expression language expressions and to send notifications about firing alerts to an external service. See here for more details.

prometheus_rule_files: <list-of-dicts> (default: [])

• specifies prometheus rule files to render

Using this role, both recording and alerting rules can be expressed within the hash, prometheus_rule_files, which contains a list of dicts encapsulating the path, name and configuration contents of a yaml or json file set to be loaded by prometheus for rule setting.

[prometheus_rule_files : <entry>:] name: <string> (default: NONE - required)

• name of rule file to render

[prometheus_rule_files : <entry>:] path: <string> (default: {{ install_dir }}/rules.d)

• path of rule file to render

[prometheus_rule_files : <entry>:] config: <list-of-dicts> (default: NONE - required)

• list of dictionaries representing settings indicating set of rule groups to specify in rule file

Example

prometheus_rule_files:
- name: example-rules.yml
 config:
   groups:
   - name: recording rule example
     rules:
     - record: job:http_inprogress_requests:sum
       expr: sum(http_inprogress_requests) by (job)
- name: nondefault-path-example-rules.yml
 path: /etc/prometheus/rules.d
 config:
   groups:
   - name: alerting rule example
     rules:
     - alert: HighRequestLatency
       expr: job:request_latency_seconds:mean5m{job="myjob"} > 0.5
       for: 10m
       labels:
         severity: page
       annotations:
         summary: High request latency

NB: An associated rule_files section is expected to be included within the prometheus.yml file for successful load.

Alertmanager Service configuration

Alertmanager service configuration can be expressed within the hash, alertmanager_config, which contains a set of key-value pairs representing one of a set of sections indicating various route, receiver, templating and alert inhibition configurations.

The values of these keys are generally dicts or lists of dicts themselves containing a set of key-value pairs representing associated specifications/settings (e.g. the API URL to use for Slack notifications) for each section. The following provides an overview and example configurations of each for reference.

:global

[alertmanager_config:] global: <key: value,...> (default: see defaults/main.yml)

• specifies parameters that are valid and serve as defaults in all other configuration contexts. See here for more details.

Example

 alertmanager_config:
   global:
     # The smarthost and SMTP sender used for mail notifications.
     smtp_smarthost: 'localhost:25'
     smtp_from: '[email protected]'
     smtp_auth_username: 'alertmanager'
     smtp_auth_password: 'password'
     # The auth token for Hipchat.
     hipchat_auth_token: '1234556789'
     # Alternative host for Hipchat.
     hipchat_api_url: 'https://hipchat.foobar.org/'

:route

[alertmanager_config:] route: <key: value,...> (default: see defaults/main.yml)

• defines a node in a routing tree and its children

Every alert enters the routing tree at the configured top-level route, which must match all alerts (i.e. not have any configured matchers). It then traverses the child nodes. If continue is set to false, it stops after the first matching child. If continue is true on a matching node, the alert will continue matching against subsequent siblings. See here for more details.

Example

 alertmanager_config:
   route:
     receiver: 'default-receiver'
     group_wait: 30s
     group_interval: 5m
     repeat_interval: 4h
     group_by: [cluster, alertname]
     # All alerts that do not match the following child routes
     # will remain at the root node and be dispatched to 'default-receiver'.
     routes:
       # All alerts with service=mysql or service=cassandra
       # are dispatched to the database pager.
     - receiver: 'database-pager'
       group_wait: 10s
       match_re:
         service: mysql|cassandra
     # All alerts with the team=frontend label match this sub-route.
     # They are grouped by product and environment rather than cluster
     # and alertname.
     - receiver: 'frontend-pager'
       group_by: [product, environment]
       match:
         team: frontend

:receivers

[alertmanager_config:] inhibit_rules: <list-of-dicts> (default: see defaults/main.yml)

• specifies a list of notification receivers

Receivers are named configuration of one or more notification integrations. See here for more details.

Example

 alertmanager_config:
   receivers:
   - name: 'team-X-mails'
     email_configs:
     - to: '[email protected]'
     pagerduty_configs:
     - service_key: <team-X-key>
     hipchat_configs:
     - auth_token: <auth_token>
       room_id: 85
       message_format: html
       notify: true

:inhibit_rules

[alertmanager_config:] inhibit_rules: <list-of-dicts> (default: see defaults/main.yml)

• specifies a list of inhibition rules

An inhibition rule mutes an alert (target) matching a set of matchers when an alert (source) exists that matches another set of matchers. See here for more details.

Example

 alertmanager_config:
   inhibit_rules:
   - source_match:
       severity: 'critical'
     target_match:
       severity: 'warning'
     # Apply inhibition if the alertname is the same.
     equal: ['alertname', 'cluster', 'service']

:templates

[alertmanager_config:] templates: <list> (default: see defaults/main.yml)

• specifies files and directories from which notification templates are read

The last component may use a wildcard matcher, e.g. templates/*.tmpl. See here for a notification template reference and this link for examples.

Example

 alertmanager_config:
   templates:
   - '/etc/alertmanager/template/*.tmpl'

Alertmanager templates

Prometheus creates and sends alerts to the Alertmanager which then sends notifications out to different receivers based on their labels. The notifications sent to receivers are constructed via templates. The Alertmanager comes with default templates but they can also be customized. See here for more details.

altermanager_templates: <list-of-dicts> (default: [])

• specifies alertmanager notification template configurations to render

Using this role, alertmanager template configuration settings can be expressed within the hash, alertmanager_templates, which contains a list of dicts representing and encapsulating the path, name and configuration contents of a tmpl file set to be loaded by alertmanager.

[alertmanager_templates : <entry>:] name: <string> (default: NONE - required)

• name of template file to render

[alertmanager_templates : <entry>:] path: <string> (default: {{ alertmgr_installdir }}/templates)

• path of template file to render

[alertmanager_templates : <entry>:] config: <list-of-dicts> (default: NONE - required)

• list of dictionaries representing settings indicating set of template configs to render

Example

 alertmanager_templates:
 - name: test
   config:
   - define: "myorg.test.guide"
     template: 'https://internal.myorg.net/wiki/alerts/\{\{ .GroupLabels.app \}\}/\{\{ .GroupLabels.alertname \}\}'
 - name: test2
   path: /etc/alertmanager/templates
   config:
   - define: "myorg.test.text"
     template: 'summary: \{\{ .CommonAnnotations.summary \}\}\ndescription: \{\{ .CommonAnnotations.description \}\}'

NB: An associated templates config section is expected to be included within the alertmanager.yml file for successful load.

Launch

This role supports launching all components of the Prometheus monitoring and alerting toolkit ecosystem. This consists of both the Prometheus and Alertmanager services and a myriad of metric exporters. Running each is accomplished utilizing the systemd service management tool which manages the services as background processes or daemons subject to the configuration and execution potential provided by its underlying management framework.

The following variables can be customized to manage the services' systemd [Service] unit definition and execution profile/policy:

Prometheus

extra_run_args: <prometheus-cli-options> (default: [])

• list of prometheus commandline arguments to pass to the binary at runtime for customizing launch.

Supporting full expression of prometheus's cli, this variable enables the launch to be customized according to the user's specification.

custom_unit_properties: <hash-of-systemd-service-settings> (default: [])

• hash of settings used to customize the [Service] unit configuration and execution environment of the Prometheus systemd service.

Alertmanager

extra_alertmgr_args: <alertmanager-cli-options> (default: [])

• list of alertmanager commandline arguments to pass to the binary at runtime for customizing launch.

Supporting full expression of alertmanager's cli, this variable enables the launch to be customized according to the user's specification.

custom_alertmgr_properties: <hash-of-systemd-service-settings> (default: [])

• hash of settings used to customize the [Service] unit configuration and execution environment of the Alertmanager systemd service.

Exporters

prometheus_exporters: <list-of-dicts> (default: [])

• specifies prometheus exporters to install and launch and manage as a systemd services.

Each exporter dict entry is expected to indicate several properties, including name; url and listen address, of the target exporter for proper setup and communication with a Prometheus server. Other properties used to customize operation of the exporter can optionally be specified via an extra_args variable, which appends provided command-line arguments to the exporter's unit ExecStart setting. See here for more details and a list of exporter plugins for reference.

[prometheus_exporters : <entry>:] name: <string> (default: NONE - required)

• name of Prometheus exporter to install

[prometheus_exporters : <entry>:] url: <string> (default: NONE - required)

• URL of Prometheus exporter to install

[prometheus_exporters : <entry>:] description: <string> (default: <exporter-name>)

• description or documentation of Prometheus exporter to include within exporter's Systemd unit file

[prometheus_exporters : <entry>:] unit_properties: <hash> (default: {})

• hash of settings used to customize the [Service] unit configuration and execution environment of the systemd service

Example

 prometheus_exporters:
   - name: node_exporter
     url: https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz
     description: https://github.com/prometheus/node_exporter
     unit_properties:
       User: exporter
       Group: exporter
     extra_args:
       - '--web.listen-address=0.0.0.0:9110'
       - '--log.level=debug'

Uninstall

Support for uninstalling and removing artifacts necessary for provisioning allows for users/operators to return a target host to its configured state prior to application of this role. This can be useful for recycling nodes and roles and perhaps providing more graceful/managed transitions between tooling upgrades.

The following variable(s) can be customized to manage this uninstall process:

perform_uninstall: <true | false> (default: false)

• whether to uninstall and remove all artifacts and remnants of this prometheus installation on a target host (see: handlers/main.yml for details)

Dependencies

• 0x0i.systemd
