Apache server 2.4 Monitoring for windows

Follow the steps for  installing Applicare SingleAgent 

Step 1: To enable server-status and custom log modules in Apache by navigating to the Apache installed directory and editing the conf file.

Step 2: Ensure the following modules are enabled in the conf file. If they are not, enable them by removing '#’ at the beginnings of the lines.

Some of the modules may not be present in the Apache conf file by default. In that cases, manually add the following modules below the Apache Listen line in the Apache conf file.

#Listen 12.34.56.78:80
Listen 80

LoadModule status_module modules/mod_status.so
LoadModule log_config_module modules/mod_log_config.so
LoadModule unique_id_module modules/mod_unique_id.so
LoadModule setenvif_module modules/mod_setenvif.so
LoadModule headers_module modules/mod_headers.so

Step 3:Ensure the LogLevel is set to warn. If it is set to a LogLevel is different value, comment out existing LogLevel line.

Step 4: Create a new log folder within the Apache home directory.

Step 5: Append the following five lines to the end of the log_config_module and section in the CustomLog and leave the existing log_config_module path unchanged.

SetEnvIfNoCase Request_URI "^/server-status/pingFromApplicare" dontlog
SetEnvIfNoCase Request_URI "^/applicare_agent/*" dontlog
SetEnvIf _ap_trace_id ^[a-zA-Z0-9].* HAVE_AP_ID
RequestHeader set _ap_trace_id "%{UNIQUE_ID}e" env=!HAVE_AP_ID
RequestHeader set _ap_apache_id "<Apache_servername>"
CustomLog "|<RotateLogPath> -n 1440 <ApacheInstalledDir>/newlogfolder/apl_log 60" "%t %h %s %B %D %U :%{_ap_trace_id}i" env=!dontlog

1. Replace <Apache_servername> with a custom name (without spaces) and include double quotes (Need to remove the angle brackets too). The name can be <Apache_servername>. But it must be unique.

2. Replace <RotateLogPath> with the path to your rotatelogs.exe file. (and remove the angle brackets). By default, it is located in the Apache installation directory <ApacheInstalledDir>/bin/rotatelogs.exe

3. Replace "<ApacheInstalledDir>" with the path to your Apache installation (and remove the angle brackets).

4. Replace <newlogfolder>with the name of the folder you created inside the Apache installation directory (add remove the angle brackets too).

Step 6:  Append the following modules to the end of the conf file.

<IfModule mod_status.c>
<Location /server-status>
ProxyPass !
SetHandler server-status
Require all granted
</Location>
</IfModule>

Step 7: Verify the configuration for syntax errors. If the output shows Syntax OK, the configuration is correct.

For httpd

httpd -t

Step 8: Finally, Restart Apache server.

After restarting the Apache server, Enter the following URL in your browser. This will display information about the apache server.

To check in browser:

<Apache_Protocol>://<Apache_IP>:<Apache_Port>/server-status?auto
Example: http://127.0.0.1:80/server-status?auto

To check using curl: 

curl <Apache_Protocol>://<Apache_IP>:<Apache_Port>/server-status?auto
Example: curl http://127.0.0.1:80/server-status?auto

<Apache_Protocol>://<Apache_IP>:<Apache_Port>/server-status?auto

<Apache_Protocol> - http (or) https
<Apache_IP> - Apache server running IP
<Apache_Port> - Apache server running port

Step 9: Start the agent by executing the startAgent.bat  in the <Agent_Home_Directory>.

Step 10: After the agent starts, It will be automatically added to the Applicare controller. Log in to the Applicare console and navigate to the Overview menu.

Step 11: Choose the newly added agent and click the Edit button.

Step 12: Check the "Add Apache Configuration" box and Set the configure the setting as shown as below. If the Apache is running over HTTPS, select HTTPS from the Apache Protocol dropdown. Click the update button to save the change.

1. Use the following command to check the configuration and virtual host details of Apache server.

httpd -S and for version httpd -V

2. If the new log configuration isn't taking effect, check whether a custom configuration is being referenced in the default configuration. Custom configuration may be included using the "IncludeOptional" keyword.

3. If the customer is wants to log only error logs to their existing log files. Add the following syntax to the end of their CustomLog configuration.

"expr=%{REQUEST_STATUS} > 200"

e.g.

CustomLog "logs/access.log" combined "expr=%{REQUEST_STATUS} > 200"
