Web Server / Services

Applications Manager supports monitoring of the following Web Services to check their status :

It performs the following checks to ensure its availability and represents the information in the form of graphs. Availability tab, gives the Availability history for the past 24 hours or 30 days. Performance tab gives the Health Status and events for the past 24 hours or 30 days. List view enables you to perform bulk admin configurations. Click on the individual monitors listed, to view the following information.

Service Type	Checks
Apache Server	Connects to the Apache and checks its availability and response time. When Server Status and Extended Status are enabled, then the following data can be obtained. 1. Total Accesses 2. Total KBs 3. CPU Load 4. Uptime 5. ReqPerSec 6. BytesPerSec 7. BytesPerReq 8. BusyWorkers 9. IdleWorkers To Enable the Server Status, follow the steps given below: 1. In Apache's httpd.conf file, locate "Location /server-status" tag. If you are not able to locate the server-status tag, do the following 2. Remove the comment in the Location/Server-status tag, to Enable SetHandler server-status 3.Change the attribute "deny from all" to "Allow from all" 4. Remove the comment in "LoadModule status_module modules/mod_status.so". 5. Save the conf file and restart the Apache Server To enable the Extended-status, follow the steps given below: 1. Locate "ExtendedStatus" Attribute in httpd.conf file. 2. Remove the comment to enable the status. 3. Save the conf file and restart the Apache Server Note : For Apache 2.2.3 and above, make the following changes in the /opt/apache-httpd-2.2.3/conf/httpd.conf file. Add the following lines at the end of the file, <Location /server-status> SetHandler server-status Order deny,allow Deny from all Allow from all </Location> ExtendedStatus On Then restart the Apache server, try to connect to http://<your.server.name>/server-status and then you should be able to view the server status.
IIS Server	Connects to the IIS server and checks its availability. Monitors response timeand updates the status based on a given threshold. If the host in which IIS server is running is monitored in WMI mode, the website stats can also be monitored. Health of the IIS Server depends upon the health of the websites. Health of the Website depends upon attributes that are mentioned below. Bytes Transferred : Bytes Sent Per Second, Bytes Received per Second, Bytes Total Per Second Files Transferred: Files Sent Per sec, Files Received Per sec, Files Transferred Per Sec Connection Statistics: Current Connections Anonymous Users: Current Annonymous Users, Anonymous Users per Second Non Anonymous Users: Current NonAnonymous Users, Non Anonymous Users per Second
PHP Monitoring	Connects to the server and retrives PHP and checks its availability. Monitors response time and updates the status based on a given threshold. In Linux, Page fault of the system in which the PHP is hosted is also shown. We can configure the alert and actions based on the threshold condition..
Web Server	Connects to the web server and checks its availability. Monitors response time and updates the status based on a given threshold.
Web Service	Connects to the web service and checks its availability. Monitors WSDL URL response time and updates the status based on a given threshold. Monitors Web Service Operation Execution time

Web Service Monitoring:

Web Services is an XML based technology that allow applications to communicate with each other, regardless of the environment, by exchanging messages in a standardized format ( XML ) via web interfaces ( SOAP and WSDL APIs ).

ManageEngine Applications Manager provides a flexible approach to manage a SOA that uses SOAP Web Services. It helps business managers to configure SLAs and track high level availablity of the Web Service. Application Admins can monitor the performance of these Web Services by configuring Applications Manager to execute "Operations" published by the Web Service. By specifying the WSDL, a simple wizard helps you configure operations that need to be invoked and gives the ability to specify arguments to the operation. In addition to this, the overall ability to configure thresholds on individual operation execution times and taking corrective actions are supported out-of-the-box.

After creating Web Services monitor , you can add Operations by clicking on Add Operations. This will list down the various Operations present in the Web Service. Select the Operations that you want to monitor and add it.

The added Operations would be listed in the details page under Operation Statistics. You can then configure thresholds and alerts for all the operations.

Editing Arguments:

Click on icon to edit the Operation Display name as well as the Arguments. The complex arguments are displayed in a tree structure. This screen shows the list of input parameters passed to the method with the parameter name and the type of parameter.
