Understanding Monitoring Services
Using the Monitoring Services facility, you test connectivity of services on one or more critical network devices, such as servers or routers. For example, you can monitor services because you want to be alerted immediately if the connectivity between the console and critical nodes is disrupted.
This test facility enables testing of the following services:
- Domain Name System (DNS)
- Dynamic Host Configuration Protocol (DHCP)
- Echo
- File Transfer Protocol (FTP)
- Hypertext Transfer Protocol (HTTP)
- Hypertext Transfer Protocol Secure (HTTPS)
- Internet Packet ExchangeTM (IPXTM)
- Internet Protocol (IP)
- Network File System (NFS)
- Network News Transfer Protocol (NNTP)
- Simple Mail Transfer Protocol (SMTP)
- Simple Network Management Protocol (SNMP)
- Time Service
- Trivial File Transfer Protocol (TFTP)
- WUser
The test facility uses the Novell ZENworks Server Management server as the remote ping server. When you select the service on the node for testing, the console interacts with the remote ping server on the Novell ZENworks Server Management server and displays the results of the test on the console.
The following figure shows a graphical representation of Monitoring Services.
To monitor nodes, you choose the nodes and enable the monitoring session for the duration you require.
From the console, you monitor the services in the following ways:
- Test connectivity of the services on a node one time only when you suspect a problem with the connectivity.
- Continuously monitor connectivity of the services on a critical node until you close the test facility.
- Continuously poll the services of the nodes on the segment (for example, connectivity testing of the services on the target nodes runs uninterrupted until you disable monitoring). If you do not disable monitoring, this test facility continues even after you close the console.
For testing connectivity of services on the target nodes you select, you set the following options:
- Specify the services on the selected target nodes.
If you need to test any TCP-based services, add the service to the existing list of services.
- Define the test interval between two successive tests.
- Define the timeout value.
The timeout value determines the time duration that the remote ping server waits to receive the response from the target node.
You can view the status of the connectivity and measure diagnostics, such as round trip delays or number of packets sent and received from the console.
Role-Based Services for Using the Monitoring Services
Role-based services (Role-based Services) defines the task for Monitoring Services as Enable Remote Ping. If this task is assigned to your role, you can use the Monitoring Services facility.
For general information about role-based traffic analysis tasks, creating Role-based Services role objects or specifying tasks that Role-based Services roles can perform, see Role-Based Administration.
