Apache Web Server Monitoring Integration
Sematext offers a simple, easy to install, Apache monitoring agent with minimal CPU and memory overhead.
Install Apache Monitoring Agent¶
Setting up the monitoring agent takes less than 5 minutes:
sudo a2enmod statusand configure it in
status.conffile, e.g. in
ExtendedStatus On <Location /server-status> SetHandler server-status </Location>
Create an Apache App in the Integrations / Overview (or Sematext Cloud Europe). This will let you install the agent and control access to your monitoring and logs data. The short What is an App in Sematext Cloud video has more details.
- Name your Apache monitoring App and, if you want to collect Apache logs as well, create a Logs App along the way.
- Install the Sematext Agent according to the https://apps.sematext.com/ui/howto/Apache/overview displayed in the UI.
