NetWatch

The Ping Response Test service

This is one of the simplest service types NetWatch supports. On discovery a single service is created that checks the device is responding to an ICMP echo request. This is the same test carried out when you use the “ping” command line tool present in virtually every operating system. The service type allows you to set the average and maximum response time that will be set in the service when it is created; if you change these default values at a later date they will have no effect. To change the average or default response time for the Ping Response Test you must configure the Ping Response Test service, not the service type.

Response Time Graphing

This can be enabled for both the Ping Response Test and the SNMP Interface test. It is configured using the configuration screen for the Ping Response Test and the SNMP Interface test. Once Response time graphing is selected the Response time graph for each service can be viewed in the Reports section. It is important to note that response time graphing does use up a lot of extra database space.

The Receive SNMP Notifications service

If a device is configured to send SNMP Notifications, or “Traps” to NetWatch, you can choose to handle them by adding this service type to the device’s configuration. See Appendix B for more information about SNMP notifications.

When you add the Receive SNMP Notifications service type to a device you must specify which of the traps the device sends you wish to record. NetWatch at the moment supports only the six standard SNMP traps. Every time a trap is received from a device with the Receive SNMP Notifications service type selected it is checked against the list of traps selected in the service type. If the trap is selected, it is recorded.

When services are discovered on a device with the SNMP Notification service type selected a service is created for each selected trap type. This allows you to alert on some of the recorded traps. For example you may wish to record link up and link down traps but alert on a cold start trap.

Configuring services

When you have discovered services on a device it is easy to change their settings from the defaults provided by the service type. When you select a service or a group of services to configure you can set most of the values you can set defaults for in the service type. In addition you can set how often NetWatch polls each service to check its status, and you can manage or unmanage a service.
