This is the Apache httpd monitoring Agent for Sematext Monitoring

Preparation

1. Get a free account at sematext.com/spm

2. Create a Monitoring App of type "Apache" and copy the Application Token - or execute the commands displayed in the Sematext UI (which are described here as well)

3. Install Node.js on your Apache httpd server

4. Activate Apache mod_status module with sudo a2enmod status and configure it in the file /etc/apache2/mods-enabled/status.conf:

<Location /server-status>
                SetHandler server-status
</Location>

Optional preparation for PHP FastCGI Process Manager (FPM): To add monitoring for PHP-FPM follow this instructions.

Setup

# Install sematext-agent-httpd 
npm i sematext/sematext-agent-httpd -g
# If you use Sematext Cloud EU, set region for API endpoints
# sematext-httpd-setup  -r EU
# Install systemd or upstart service file for sematext-agent-httpd 
sematext-httpd-setup -t YOUR_SPM_TOKEN_HERE -u http://localhost/server-status

Configuration

The setup script stores the configuration in /etc/sematext/sematext-agent-httpd.config

In case you want to change settings later edit /etc/sematext/sematext-agent-httpd.config. Restart the Sematext Apache Agent after config changes, depending on the init system:

• Upstart (Ubuntu):

    sudo service sematext-agent-httpd restart 

• Systemd (Linux others):

    sudo systemctl stop sematext-agent-httpd
    sudo systemctl start sematext-agent-httpd

• Launchd (Mac OS X):

    sudo launchctl stop com.sematext.sematext-agent-httpd
    sudo launchctl stop com.sematext.sematext-agent-httpd

For tests you can just run the agent from command line:

sematext-agent-httpd --config /etc/sematext/sematext-agent-httpd.config
