Lighttpd integration

Manually configure the lighttpd.conf file

To export metrics on the url http://INSERT_DOMAIN:INSERT_PORT/server-status?json, use the following steps:

1. Go to lighttpd config file path.

   bash

   Copy

   $
   cd /etc/lighttpd/

2. Open lighttpd.conf file to edit.

   bash

   Copy

   $
   sudo nano lighttpd.conf

3. Add mod_status inside server.modules object.

4. Add status.status-url = /server-status after server.modules.

5. Update server.document-root with the lighttpd file path /var/www/html/lighttpd-webpage

6. Update server.port on which you're running lighttpd.

   server.port = 9880.

   Copy

7. Open http://INSERT_DOMAIN:INSERT_PORT/server-status?json on the browser to check server related metrics.

   Here is a sample configuration file:

   server.modules = (
       "mod_indexfile",
       "mod_access”,
       "mod_alias",
       "mod_redirect”,
       "mod_status"
   )
   
   server.document-root    = "/var/www/html/lighttpd-webpage"
   server.upload-dirs    = ( "/var/cache/lighttpd/uploads" )
   server.errorlog         = "/var/log/lighttpd/error.log"
   server.pid-file         = "/run/lighttpd.pid"
   server.username         = "www-data"
   server.groupname        = "www-data"
   server.port             = 9880
   status.status-url       = "/server-status”

   Copy

NRI-Flex configuration

Once you've installed the infrastructure agent on your host, nri-flex binary is also installed with it.

If the infrastructure agent was not installed, follow the installation steps of nri-flex from nri-flex repository.

To create a flex configuration file follow these steps:

1. Create a file named lighttpd-http-config.yml in this path:

   bash

   Copy

   $
   /etc/newrelic-infra/integrations.d

2. Update the file lighttpd-http-config.yml with these configurations:

   • EVENT_TYPE: You can consider EVENT_TYPE as a New Relic database table that you can query using NRQL (for example, LighttpdStatusSample).
   • URL: This contains the json-formatted metrics (for example, http://127.0.0.1:9880/server-status?json).

   Here is a sample configuration file:

   ---
   integrations:
     - name: nri-flex
       # interval: 30s
       config:
         name: lighttpdFlex
         apis:
           - event_type: INSERT_EVENT_TYPE
             url: INSERT_URL

   Copy

Forward Lighttpd logs to New Relic

You can use our log forwarding to forward Lighttpd logs to New Relic.

On Linux machines, your log file named logging.yml should be present in the path below. If you don't see your log file, then you will need to create it by following the above log forwarding documentation.

$
/etc/newrelic-infra/logging.d/

Once the log file is created, add the following script to the logging.yml file:

- name: error.log
    file: /var/log/lighttpd/error.log
    attributes:
      logtype: lighttpd_log

Restart the New Relic infrastructure agent and lighttpd service

Before you can start reading your data, use the instructions in our infrastructure agent docs to restart your infrastructure agent.

$
sudo systemctl restart lighttpd.service && sudo systemctl restart newrelic-infra.service

Monitor your application

You can choose our pre-built dashboard template named Lighttpd to monitor your Lighttpd server metrics. Follow these steps to use our pre-built dashboard template:

1. Go to one.newrelic.com and click on + Integrations & Agents.

2. Click on the Dashboards tab.

3. In the search box, type lighttpd.

4. When you see our pre-build dashboard, click on it to install it in your account.

   Once your application is integrated by following the above steps, the dashboard should display metrics.

   To instrument the Lighttpd quickstart and to see metrics and alerts, you can also follow our Lighttpd quickstart page that has an Install now button.

   Here are some example queries:

   Example: View the captured metrics on the New Relic query builder.

   SELECT * FROM LighttpdStatusSample  LIMIT MAX

   Copy

   Example: Check the active connection per server.

   SELECT latest(BusyServers) FROM LighttpdStatusSample TIMESERIES AUTO

   Copy
