Adapters as a Service

In some cases, users may need to install the LimaCharlie Adapter with persistence, to ensure that data collection survives a reboot and/or other disruptions.  

To accommodate this need, the LimaCharlie adapter can be installed as a service.  

Service Installation  

Windows

To install the Windows LimaCharlie adapter as a service, insert the -install:<service_name> flag in the command line, following the adapter executable name.  

For example:  

./lc_adapter.exe azure_event_hub client_options.identity.installation_key=...

would be replaced with  

./lc_adapter.exe -install:azure_collection azure_event_hub client_options.identity.installation_key=...

This would create a service named azure_collection with the adapter config.

Remember, adapter configurations can be provided via two methods:

• In the command line, as part of a list of flags

• Via a YAML config file  

Note: The service will point to lc_adapter.exe based on its path at the creation of the service. If you wish to move the adapter to a permanent location, please do so before creating the service.  

Linux / systemd  

To install a LimaCharlie adapter as a service on a Linux system with systemd, you will need a service file, the adapter binary, and your adapter command.  

Adapter Binary  

Download one of the adapter binaries and apply the necessary permissions:

wget -O /path/to/adapter-directory/lc-adapter $ADAPTER_BINARY_URL 
chmod +x /path/to/adapter-directory/lc-adapter 

Service File - /etc/systemd/system/limacharlie-adapter-name.service

You will replace $ADAPTER_COMMAND in the service file with your actual adapter command below.  

[Unit]
Description=LC Adapter Name
After=network.target

[Service]
Type=simple
ExecStart=$ADAPTER_COMMAND
WorkingDirectory=/path/to/adapter-directory
Restart=always
RestartSec=10
StandardOutput=journal
StandardError=journal
SyslogIdentifier=lc-adapter-name

[Install]
WantedBy=multi-user.target

Adapter Command  

Your adapter command may differ depending on your use case--this is an example of a file adapter to ingest logs from a JSON file.

/path/to/adapter-directory/lc-adapter file file_path=/path/to/logs.json client_options.identity.installation_key=<INSTALLATION KEY> client_options.identity.oid=<ORG ID> client_options.platform=json client_options.sensor_seed_key=<SENSOR SEED KEY> client_options.mapping.event_type_path=<EVENT TYPE FIELD> client_options.hostname=<HOSTNAME> 

Enable and Start the Service

sudo systemctl enable lc-adapter-name
sudo systemctl start lc-adapter-name
sudo systemctl status lc-adapter-name

Service Uninstallation  

Windows  

To remove a Windows LimaCharlie Adapter service, use the -remove:<service_name> flag.  

Linux  

If your service is running with a systemd script, you can disable and remove it with the following:  

sudo systemctl stop lc-adapter-name
sudo systemctl disable lc-adapter-name
sudo rm /etc/systemd/system/lc-adapter-name.service
sudo rm /path/to/adapter-directory/lc-adapter
