Appendix C. Probes 239C.8.10. Network Services::SSHThe Network Services::SSH probe determines the availability of SSH on the specified portand collects the following metric:• Remote Service Latency — The time it takes in seconds for the SSH server to answer aconnection request.Upon successfully contacting the SSH server and receiving a valid response, the probe dis-plays the protocol and server version information. If the probe receives an invalid response,it displays the message returned from the server and generates a WARNING state.Field ValueSSH Port* 22Timeout* 5Critical Maximum Remote Service LatencyWarning Maximum Remote Service LatencyTable C-46. Network Services::SSH settingsC.8.11. Network Services::Web Server (HTTP)The Network Services::Web Server (HTTP) probe determines the availability of the Webserver and collects the following metric:• Remote Service Latency — The time it takes in seconds for the HTTP server to answera connection request.This probe confirms it can connect to the HTTP port on the specified host and retrieve thespecified URL. If no URL is specified, the probe will fetch the root document. The probelooks for a HTTP/1. message from the system, unless you alter that value. Specifyinganother port number will override the default port of 80. Unlike most other probes, thisprobe will return a CRITICAL status if it cannot contact the system within the timeoutperiod.This probe supports authentication. Provide a username and password in the appropriatefields to use this feature. Also, the optional Virtual Host field can be used to monitor aseparate documentation set located on the same physical machine presented as a standaloneserver. If your Web server is not configured to use virtual hosts (which is typically the case),you should leave this field blank. If you do have virtual hosts configured, enter the domainname of the first host here. Add as many probes as necessary to monitor all virtual hostson the machine.
