veeam_exporter

Description

Prometheus exporter for Veeam Entreprise Manager

This exporter collect metrics from Veeam Enterprise Manager HTTP API.

It is a python HTTP server that exposes metrics to http (default port 9247) that can be then scrapped by Prometheus.

Several Veeam server can be polled by adding them to the YAML config file, by adding a host section:

Config: (see config.yml)

veeams:
  - host: host.domain
    port: 9398
    user: 'user'
    password: 'password'
#   protocol: https
#   verify_ssl: false
#   timeout: 20
#   keep_session: true # default
#   default_labels:
#     - name: veeam_em
#       value: my_veeam_em_server.domain
#       proxy:
#         url: http://my.proxy.domain:port/
#         protocol: https

weblisten:
  address: 0.0.0.0
  port: 9247

logger:
  level: info
  facility: syslog

metrics_file: "conf/metrics/*_metrics.yml"

Usage

The exporter may run as a unix command with module installation or as standalone python script without instalation.

the easiest wayt is to install from pip:

pip3 install --upgrade veeam_exporter

then you can use the entry point create by the installer of the module in /usr/local/bin/veeam_exporter or in [venv]/bin/veeam_exporter for venv context. The commanded usage is in venv.

To use the exporter, few packages needs to be installed. This can be done using:

pip3 install -r pip_requirements.txt

Prometheus-client>=0.8.0
requests==2.23.0
PyYAML==5.3.1
tenacity==6.2.0
urllib3>=1.25.9
Jinja2>=2.11.2
python-dateutil>=0.6.12

• Consider, to extract the archiv file in /tmp folder; this will generate a folder /tmp/veeam_exporter_[version].
• create a directory where you want by example /opt/veeam_exporter_[version],
• move the /tmp/veeam_exporter_[version]/veeam_exporter_package directory to /opt/eeam_exporter_[version]
• create a command file to launch the exporter in dir /opt/veeam_exporter_[version]

vi /opt/veeam_exporter_X.Y.Z/veeam_exporter_cmd
#!/usr/libexec/platform-python
# -*- coding: utf-8 -*-
import re
import sys
from veeam_exporter.veeam_exporter import main
if __name__ == '__main__':
    sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
    sys.exit(main())

• Then edit the conf/config.yml file and add your settings.
• Try your config by executing the command in try mode

example with the default dumy config file:

python3 veeam_exporter_cmd -n -v
veeam_exporter[647132]: level=INFO - veeam_exporter 1.0.3 starting....

exporter command line options

to start the exporter:

./veeam_exporter &

By default, it will load the file config.yml to perform action.

Usage: veeam_exporter [-h] [-b BASE_PATH] [-c CONFIG_FILE]
                      [-f LOGGER.FACILITY] [-l {error,warning,info,debug}]
                      [-o  METRICS_FILE] [-m  METRIC] [-n] [-t  TARGET]
                      [-w WEB.LISTEN_ADDRESS] [-V] [-v]

collector for veeam server.

optional arguments:
  -h, --help            show this help message and exit
  -b BASE_PATH, --base_path BASE_PATH
                        set base directory to find default files.
  -c CONFIG_FILE, --config_file CONFIG_FILE
                        path to config files.
  -f LOGGER.FACILITY, --logger.facility LOGGER.FACILITY
                        logger facility (syslog or file path).
  -l {error,warning,info,debug}, --logger.level {error,warning,info,debug}
                        logger level.
  -o  METRICS_FILE, --metrics_file METRICS_FILE
                        collect the metrics from the specified file instead of
                        config.
  -m  METRIC, --metric METRIC
                        collect only the specified metric name from the
                        metrics_file.
  -n , --dry_mode       collect the metrics then exit; display results to
                        stdout.
  -t  TARGET, --target TARGET
                        In dry_mode collect metrics on specified target.i
                        Default first from config file.
  -w WEB.LISTEN_ADDRESS, --web.listen-address WEB.LISTEN_ADDRESS
                        Address to listen on for web interface and telemetry.
  -V, --version         display program version and exit..
  -v , --verbose        verbose mode; display log message to stdout.

To test your configuration you can launch the exporter in dry_mode:

./veeam_exporter -v -n -t host.domain

This command will try to connect to the 'host.domain' veeam server with parameters specified in config.yml, expose the collected metrics, and eventually the warning or errors, then exits.

Prometheus config

Since several veeam servers can be set in the exporter, Prometheus addresses each server by adding a target parameter in the url. The "target" must be the same (lexically) that in exporter config file.

  - job_name: "veeam"
    scrape_interval: 120s
    scrape_timeout: 60s
    metrics_path: /metrics

    static_configs:
      - targets: [ veeamhost.domain ]
        labels:
          environment: "PROD"
#    file_sd_configs:
#      - files: [ "/etc/prometheus/veeam_exp/*.yml" ]
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: "veeam-exporter-hostname.domain:9247"  # The veeam exporter's real hostname.

Metrics

The collected metrics are defined in separeted files positionned the folder conf/metrics. All Values, computations, labels are defined in the metrics files, meaning that the exporter doesn't nothing internally on values. The configuration fully drive how values are rendered.

Collected Metrics

All metrics are defined in the configuration file (conf/metrics/*.yml). You can retrive all metric names here. Most of them have help text too.

Extending metrics

Exported metrics, are defined the YAML config file. The value can use Jinja2 templating language. The format of the configuration is inspired from Ansible task representation. So a metric configuration file, consists in a list of action to perform.

There are five possible actions:

• url: to collect metrics from HTTP API
• set_fact: to assign vlaue to variables
• actions: to perform a list of (sub-)actions
• metrics: to define metrics to expose/return to Prometheus
• debug: to display debug text to logger.

All actions have default "attributes":

• name: the name of action or metric counter for metrics action.
• vars: to set vars to global symbols' table.
• with_items: to loop on current action with a list of items.
• loop_var: to set the name of the variable that will receive the current value in the loop. Default is 'item'.
• when: a list of condition (and) that must be check and be true to perform the action.

The "attributes" are analyzed in the order specified in previous table; it means that you can't use "item" var (obtained from 'with_items' directive) in the vars section because it is not yet defined when the 'vars' section is evaluated. If you need that feature, you will have to consider 'with_items' in an 'actions' section (see metrics/backup_jobs_sessions_metrics.yml).
