Network Services::RPCServiceThe Network Services::RPCService probe tests the availability of remote procedure call (RPC) pro-grams on a given IP address. It collects the following metric:• Remote Service Latency — The time it takes in seconds for the RPC server to answer a connectionrequest.RPC server programs (which provide function calls via that RPC network) register themselves in theRPC network by declaring a program ID and a program name. NFS is an example of a service thatworks via the RPC mechanism.Client programs that wish to use the resources of RPC server programs do so by asking the machineon which the server program resides to provide access to RPC functions within the RPC programnumber or program name. These conversations can occur over either TCP or UDP (but are almostalways UDP).This probe lets you test simple program availability. You will need to specify the program name orprogram number and the protocol over which the conversation will occur (plus the usual timeout).Field ValueProtocol (TCP/UDP) udpService Name* nfsTimeout* 10Critical Maximum Remote Service LatencyWarning Maximum Remote Service LatencyTable C-44.

Network Services::Secure Web Server (HTTPS)The Network Services::Secure Web Server (HTTPS) probe determines the availability of the secureWeb server and collects the following metric:• Remote Service Latency — The time it takes in seconds for the HTTPS server to answer a connec-tion request.This probe confirms it can connect to the HTTPS port on the specified host and retrieve the specifiedURL. If no URL is specified, the probe will fetch the root document. The probe looks for a HTTP/1.message from the system, unless you alter that value. Specifying another port number will overridethe default port of 443.This probe supports authentication. Provide a username and password in the appropriate fields to usethis feature. Unlike most other probes, this probe will return a CRITICAL status if it cannot contactthe system within the timeout period.
