Installing Logagent on Linux
Logagent is a general purpose log shipper. It runs as a system service on Linux by using Systemd or Upstart.
Install Node.js on your server¶
First, make sure you have Node.js 8.11 or later installed. E.g. for Debian/Ubuntu:
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install -y nodejs
Install the Logagent npm package¶
sudo npm i -g @sematext/logagent
Run Logagent and ship logs¶
1. Register for a free account at Sematext.com¶
2. Create a Logs App to get a Logs Token for Sematext Logs¶
3. Run Logagent as System Service¶
By running the logagent-setup command, Logagent will detect the init system and install Systemd or Upstart service scripts.
-
Ship logs to default US region
sudo logagent-setup -i LOGS_TOKEN
-
Ship logs to EU region
sudo logagent-setup -i LOGS_TOKEN -u logsene-receiver.eu.sematext.com
-
Ship logs to any Elasticsearch endpoint
sudo logagent-setup -i index -u http://localhost:9200
Changing the Elasticsearch index and endpoint lets you ship logs to any Elasticsearch cluster. After running logagent-setup the agent will start shipping logs immediately.
Location of service scripts¶
- Systemd:
/etc/systemd/system/logagent.service - Upstart:
/etc/init/logagent.conf
Check service status¶
- Systemd:
systemctl status logagent - Upstart:
service logagent status
Start/stop service¶
- Systemd:
systemctl stop/start logagent - Upstart:
service logagent stop/start
4. Configure Logagent settings¶
The setup script generates the configuration file in /etc/sematext/logagent.conf. The default settings will ship all log files from the /var/log directory to Sematext Cloud. Here's the configuration guide.
