Introduction

The Observability Agent autoconfiguration and installer tool is a wrapper for Grafana Alloy that can install Alloy, detect which services are running on your machine, and automatically create a configuration file with integrations for detected services. A Node/Windows exporter integration will be added by default.

Prerequisites

For Unix machines, the script will have to be run with root privileges, otherwise you will be prompted for your password during execution. Windows machines must have Powershell 5.1 or later installed. macOS is not currently supported.

The script will automatically detect what's running on your machine and add integrations to the config file. For this, each service you want to have an integration for must be running on its default port, these are:

Integration	Default Port
MySQL	3306
MSSQL	1433
Postgres	5432
RabbitMQ	5672
RabbitMQ Exporter	15692
Redis	6379
Kafka	9092
Elasticsearch	9200
Mongo	27017
OracleDB	1521

Procedure

Both the Static Mode installer and Flow Mode installer have been deprecated and superseded by Grafana Alloy installer

Latest Release

Linux

To download and run the installer, in a terminal, run:

curl -O -L "https://github.com/intergral/observability-agent/releases/download/v0.2.3/observability-agent-autoconf.sh"
chmod a+x "observability-agent-autoconf.sh"
sudo /bin/bash observability-agent-autoconf.sh

Windows

To download and run the installer, open powershell admin terminal, navigate to your desired download folder and run:

Invoke-WebRequest -Uri "https://github.com/intergral/observability-agent/releases/download/v0.2.3/observability-agent-autoconf.ps1" -OutFile "observability-agent-autoconf.ps1"
.\observability-agent-autoconf.ps1

The installer for windows assumes you are installing Grafana Alloy in the default location on the C drive
This is required for the config file to be placed in the correct location for the Grafana Alloy to read it

Options

Grafana Alloy installation is enabled by default. To run without installing Alloy, add --install false to the end of the run command. For example:
sudo path/to/observability-agent-autoconf.sh --install false

To modify a pre-existing config file, add --config.file, followed by the path to the file, to the end of the run command. For example: sudo path/to/observability-agent-autoconf.sh --config.file path/to/configfile
A backup of your original file will be created

To disable prompts that wait for user input, add --prompt false as command arguments.

You can use both --install and --config.file options in the same run command, order is irrelevant. For example:
sudo path/to/observability-agent-autoconf.sh --install false --config.file path/to/config
or
sudo path/to/observability-agent-autoconf.sh --config.file path/to/config --install false

For Windows, you can add --disable-dl-progress-bar true to potentially speed up downloads.

Docker

When running in Docker, you will not be prompted for any information. Therefore, you must specify an api key before running. Additionally, you must set the relevant environment variables for whichever services you have running, so they can be configured. These environment variables can be found in the Environment Variables section.

To run in docker, we provide prebuilt images. See our Docker Hub repository for more information

Environment Variables

To add integrations without being prompted for credentials, there are several environment variables you can use:

Ingest

Variable	Type	Description
api_key	string	API Key to authenticate with your FusionReactor Cloud Account
metrics_Endpoint	string	Default: https://api.fusionreactor.io/v1/metrics
logs_Endpoint	string	Default: https://api.fusionreactor.io/v1/logs

Metric Exporters

Variable	Type	Description
mysql_user	string	User for the local Mysql database
mysql_password	string	Password for the local Mysql database
mysql_disabled	bool	Enables/Disables the Mysql exporter (enabled by default)
mssql_user	string	User for the local Mssql database
mssql_password	string	Password for the local Mssql database
mssql_disabled	bool	Enables/Disables the Mssql exporter (enabled by default)
postgres_user	string	User for the local Postgres database
postgres_password	string	Password for the local Postgres database
postgres_db	string	Database name for the local Postgres database (defaults to username)
postgres_disabled	bool	Enables/Disables the Postgres exporter (enabled by default)
rabbitmq_disabled	bool	Enables/Disables the RabbitMQ exporter (enabled by default)
rabbitmq_instance_label	string	Optional variable to set the RabbitMQ instance identifier
redis_disabled	bool	Enables/Disables the Redis exporter (enabled by default)
elasticsearch_user	string	User for the Elastic search instance
elasticsearch_password	string	Password for the Elastic search instance
elasticsearch_disabled	bool	Enables/Disables the Elastic search exporter (enabled by default)
mongodb_user	string	User for the local Mongo database
mongodb_password	string	Password for the local Mongo database
mongodb_disabled	bool	Enables/Disables the MongoDB exporter (enabled by default)
oracledb_user	string	User for the local Oracle database
oracledb_password	string	Password for the local Oracle database
oracledb_disabled	bool	Enables/Disables the OracleDB exporter (enabled by default)

Exporting metrics from external machines

To replace these with a custom connection string, there are several environment variables you can use:

Variable	Type	Example (Defaults)
mysql_connection_string	string	<username>:<password>@(<host>:3306)/
mssql_connection_string	string	sqlserver://<username>:<password>@<host>:1433
postgres_connection_string	string	postgresql://<username>:<password>@<host>:5432/shop?
rabbitmq_scrape_target	string	<host>:15692
redis_connection_string	string	<host>:6379
kafka_connection_string	string	["<host>:9092"]
elasticsearch_connection_string	string	http://<username>:<password>@<host>:9200
mongodb_connection_string	string	mongodb://<username>:<password>@<host>:27017/
oracledb_connection_string	string	oracle://<username>:<password>@<host>:1521/ORCLCDB

RabbitMQ requires an internal exporter to be enabled. Visit the documentation for more information.

Log Exporters

If you wish to enable log collection, the following environment variables must be set:

Variable	Type	Example	Description
log_collection	bool	true	Enables log collection
service_name	string	service	Set a name for you log collection service
log_path	string	/service/logs	Set a file path for your log collection service

Open Telemetry

If you wish to enable Open Telemetry metrics and traces, the following environment variables must be set:

Variable	Type	Example	Description
otel_collection	bool	true	Enables Open Telemetry metrics and traces

Scraping from additional exporters

At present, there are some integrations we don't support out the box. Use of these integrations is via a scrape endpoint. To scrape these exporters, you can use the following environment variables to set a list of exporters and their corresponding endpoints to be scraped. The list must be wrapped in double quotes and each value must be separated by a comma and a space.

Variable	Type	Example	Description
scrape_targets	string	"nginxexporter:9113, iisexporter:1234"	List of endpoints for the exporters

.Env Files

If you wish to use an environment file to set environment variables, rather than setting them as system environment variables, you can do so by naming the file ".env" and placing it in the same directory as the "observability-agent-autoconf" script.

Example ".env" file:

api_key=1234567890
mysql_connection_string=root:my-secret-pw@(mysql:3306)/
log_collection=true
service_name=service
log_path=path
