Apache server Monitoring with Applicare
Note: Some of the modules may not be present in the apache conf file by default. In that case add the module lines manually below the Apache Listen line in the apache conf file.
#Listen 12.34.56.78:80

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.soStep 1: To enable server-status and custom log modules in apache. Go to <ApacheHomeDir>/conf and edit httpd.conf file as below.
1. Check status_module is enabled, if not enable it by just removing '#’ before the
LoadModule status_module modules/mod_status.so
[Screenshot 1 is not available on this page.]
2. Search for <Location /server-status> and add the "Required or Order" commands inside the <Location /server-status> based on the Apache version. If the <Location /server-status> is there then add the below modules at the end of the conf file based on the apache versions.
For Apache 2.2
<IfModule mod_status.c> <Location /server-status> SetHandler server-status Order allow,deny Allow from all </Location> </IfModule>
For Apache 2.4
<IfModule mod_status.c> <Location /server-status> SetHandler server-status Require all granted </Location> </IfModule>

For Apache version 2.2
7. Create a new log folder inside the apache home directory.
8. Add the below 4 lines inside the log_config_module and comment other ‘CustomLog's inside the log_config_module in the httpd.conf file.
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"
For Windows add the below line next to the RequestHeader set _ap_apache_id "Apache" line.
CustomLog "|<ApacheHomeDir>/bin/rotatelogs.exe <ApacheHomeDir>/newlogfolder/apl_log 60" "%t %h %s %B %D %U :%{_ap_trace_id}i" env=!dontlog
For Linux add the below line next to the RequestHeader set _ap_apache_id "Apache" line.
CustomLog "|<ApacheHomeDir>/bin/rotatelogs <ApacheHomeDir>/newlogfolder/apl_log 60" "%t %h %s %B %D %U :%{_ap_trace_id}i" env=!dontlog
Note:
1. Replace the "<ApacheHomeDir>" with your apache installed path (Need to remove the angle brackets also).
2. Replace the "Apache" with Apache servername (without space) and double quotes should be there. You can give any name in the Apache servername, But it should be unique.
3. Replace the newlogfolder with the folder name which you have created inside the apache home directory.

1. First, you will have to build the stand-alone collector. Once you install Applicare you can build
the stand-alone agent by running
<ApplicareServer Install Dir>/agent/Standalonecollector/build/ build_collector.bat/sh
[Screenshot 11 is not available on this page.]
This will create a new folder,
<Applicare Server Install Dir>/agent/Standalonecollector/Applicare
and,
<Applicare Install Dir>/agent/Standalonecollector/Applicare.jar
2. If you are going to deploy the agent in the new machine then copy the "Applicare" folder or "Applicare.jar " from the Applicare server machine to agent machine and extract in any directory.
[Screenshot 12 is not available on this page.]
Please make sure that on Linux environment you assign appropriate read/write permission to extracted/copied Applicare folder/jar. Additionally, run the following command from the extracted/copied folder to assign execute permission to all the .sh script files.
chmod +x *.sh
3. To start the agent application run, Applicare/server/bin/startup.bat/sh
4. Please note that the agent by default runs on port 9880. You can change the port number by modifying Applicare /server/conf/server.xml
[Screenshot 13 is not available on this page.]
5. Set "SERVER_NAME" and "JAVA_HOME" property in the agent "Catalina.bat/sh" file before starting the agent.
Go to the path Applicare/server/bin/catalina.bat/sh
Edit Catalina.bat/sh and set the "SERVER_NAME" &
"JAVA_HOME" and save the file.
SERVER_NAME - You can give any name without spaces.
JAVA_HOME - Java JDK path of the Agent machine.
Note: For every agent, the SERVER_NAME should be unique.
For Windows edit Catalina.bat file and save
[Screenshot 14 is not available on this page.]
For Linux edit**, Catalina.sh** file and save
