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`:
`

SetHandler server-status

`

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

Setup


`sh

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
`
