Application's Manager's Apache Monitoring tool helps to gain smooth user experience of the web server.
Creating a new Apache server monitor
Prerequisites for monitoring Apache web server metrics:Click here
Using the REST API to add a new Apache server monitor:Click here
To create an Apache monitor, follow the steps given below:
- Click on New Monitor link. Choose Apache Server.
- Enter the hostname or IP Address (IPv4/IPv6) of the host in which the monitor is running.
- Enter the Subnet Mask of the network.
- Provide the port number in which the Apache server is running.
- Enter the credential details like user name and password for authentication, or select the required credentials from the Credential Manager list after choosing the Select from Credential list option.
- Enable the Authentication is enabled option if authentication is needed for connection to the Apache Server. Then, specify the User Name and Password if the Apache Server is authenticated.
- Choose SSL option, if SSL is enabled in Apache Server.
- Enable the Modify Apache Status URL option if you need to modify the Apache Status URL which is used for fetching the performance metrics from Apache Server. Once enabled, modify the Server status URL of the Apache server if it differs from the default value. By default, Applications Manager collects data transfer and access details from the following URL: http://<host-name:portNumber>server-status?auto.
- Enter the polling interval time in minutes.
- If you are adding a new monitor from a Central Server, select a Probe Server.
- Choose the Monitor Group from the combo box with which you want to associate Apache Monitor (optional). You can choose multiple groups to associate your monitor.
- Click Add Monitor(s). This discovers the Apache from the network and starts monitoring them.
Note:
Security/Firewall Requirements: The Apache server host and port should be accessible from the Applications manager installed machine.
Monitored Parameters
