Netwatch monitors the state of hosts on the network. Monitoring can be done with the following probe types:
1) ICMP - pings to a specified IP address - hosts, with an option to adjust threshold values
2) Simple - uses ping, without use of advanced metrics
3) TCP conn, to test the TCP connection
4) HTTP GET/HTTPS GET, request against a server you are monitoring
For each entry in the Netwatch table, you can specify an IP address, ping interval, and console scripts. The main advantage of Netwatch is its ability to issue arbitrary console commands on host state changes.
Info |
---|
Since 7.4, Netwatch functionality has been expanded, prior versions only support simple ICMP probes. While upgrading to the new version, old Netwatch entries will be unchanged, reporting probe type "simple" - preserving the same functionality. |
Note |
---|
Default Netwatch values are always used - even if they were not defined by the user. Make sure to check the "status" page of the probe to see if the default thresholds are appropriate for your use case. Default threshold values can be found under the "probe options" section on this page. |
