14.9 Monitoring the IBM HTTP Server
The IBM HTTP Server server-status page is available on all supported IBM HTTP Server platforms. It shows performance data on a Web page in HTML format.
Perform the following steps to activate the server-status page:
| 1. | Open the IBM HTTP Server file httpd.conf in an editor. |
| 2. | Remove the comment character "#" from the following lines: |
#LoadModule status_module modules/mod_status.so
#<Location /server-status>
# SetHandler server-status
# Order deny,allow
# Deny from all
# Allow from .example.com
#</Location>
| 3. | Customize the ".example.com" in the sample configuration to match your source workstation reverse DNS entry so you're allowed to access the page. In our example this must be changed to: |
Allow from .itso.ibm.com
| 4. | Save the changes and restart the IBM HTTP Server. |
| 5. | Open the URL http://<yourhost>/server-status in a Web browser, and click Refresh to update the status. |
If your browser supports refresh, you can also use the URL http://<yourhost>/server-status?refresh=5 to refresh every 5 seconds. As shown in Figure 14-20, you can see (along with additional information) the number of requests currently being processed, and the number of idle servers.
