# Apache > THIS MODULE IS OBSOLETE. > USE [THE PYTHON ONE](../../python.d.plugin/apache) - IT SUPPORTS MULTIPLE JOBS AND IT IS MORE EFFICIENT --- The `apache` collector visualizes key performance data for an apache web server. ## Example Netdata charts For apache 2.2: ![image](https://cloud.githubusercontent.com/assets/2662304/12530273/421c4d14-c1e2-11e5-9fb6-ca6d6dd3b1dd.png) For apache 2.4: ![image](https://cloud.githubusercontent.com/assets/2662304/12530376/29ec26de-c1e6-11e5-9af1-e48aaf781795.png) ## How it works It runs `curl "http://apache.host/server-status?auto` to fetch the current status of apache. It has been tested with apache 2.2 and apache 2.4. The latter also provides connections information (total and break down by status). Apache 2.2 response: ```sh curl "http://127.0.0.1/server-status?auto" Total Accesses: 80057 Total kBytes: 223017 CPULoad: .018287 Uptime: 64472 ReqPerSec: 1.24173 BytesPerSec: 3542.15 BytesPerReq: 2852.59 BusyWorkers: 1 IdleWorkers: 49 Scoreboard: _________________________......................................._W_______________________....................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................... ``` Apache 2.4 response: ```sh curl "http://127.0.0.1/server-status?auto" 127.0.0.1 ServerVersion: Apache/2.4.18 (Unix) ServerMPM: event Server Built: Dec 14 2015 08:05:54 CurrentTime: Saturday, 23-Jan-2016 14:42:06 EET RestartTime: Saturday, 23-Jan-2016 04:57:13 EET ParentServerConfigGeneration: 2 ParentServerMPMGeneration: 1 ServerUptimeSeconds: 35092 ServerUptime: 9 hours 44 minutes 52 seconds Load1: 0.32 Load5: 0.32 Load15: 0.27 Total Accesses: 32403 Total kBytes: 34464 CPUUser: 30.37 CPUSystem: 29.55 CPUChildrenUser: 0 CPUChildrenSystem: 0 CPULoad: .170751 Uptime: 35092 ReqPerSec: .923373 BytesPerSec: 1005.67 BytesPerReq: 1089.13 BusyWorkers: 1 IdleWorkers: 99 ConnsTotal: 0 ConnsAsyncWriting: 0 ConnsAsyncKeepAlive: 0 ConnsAsyncClosing: 0 Scoreboard: __________________________________________________________________________________________W_________............................................................................................................................................................................................................................................................................................................ ``` From the apache status output it collects: - total accesses (incremental value, rendered as requests/s) - total bandwidth (incremental value, rendered as bandwidth/s) - requests per second (this appears to be calculated by apache as an average for its lifetime, while the one calculated by Netdata using the total accesses counter is real-time) - bytes per second (average for the lifetime of the apache server) - bytes per request (average for the lifetime of the apache server) - workers by status (`busy` and `idle`) - total connections (currently active connections - offered by apache 2.4+) - async connections per status (`keepalive`, `writing`, `closing` - offered by apache 2.4+) ## Configuration The configuration is stored in `/etc/netdata/charts.d/apache.conf`. To edit this file on your system run `/etc/netdata/edit-config charts.d/apache.conf`. The internal default is: ```sh # the URL your apache server is responding with mod_status information. apache_url="http://127.0.0.1:80/server-status?auto" # use this to set custom curl options you may need apache_curl_opts= # set this to a NUMBER to overwrite the update frequency # it is in seconds apache_update_every= ``` The default `apache_update_every` is configured in Netdata. ## Auto-detection If you have configured your apache server to offer server-status information on localhost clients, the defaults should work fine. ## Apache Configuration Apache configuration differs between distributions. Please check your distribution's documentation for information on enabling apache's `mod_status` module. If you are able to run successfully, by hand this command: ```sh curl "http://127.0.0.1:80/server-status?auto" ``` Netdata will be able to do it too. Notice: You may need to have the default `000-default.conf` website enabled in order for the status mod to work.
