Hi all, I want a perl ping script (console based) to monitor server up/down state.
So far I have tried two different approaches, though none of them were successful. *First Approach* Call the operating system "ping" command from the Perl program and get the server up/down state. Call this program every few minutes using operating system specific scheduler. *Second Approach* Instead of operating system "ping", use "Net::Ping" module from CPAN. The program with both the approaches are that they are reactive in nature rather than proactive. If the server goes down and goes up again between two consecutive instances of perl program execution, the perl program will never get to know about the same. Lowering the interval might help here but instead increases the workload on the server (probably). Having said all that, I have following doubts. 1. Is there a way to implement a daemon sort of a thing in Perl which will continuously listen at one port and proactively monitor the "ping" state of the server ? 2. I have heard about SNMP and also know about perl Net::SNMP and SNMP modules. Will they be of any help here ? Thanks & Regards, Amit Saxena
