Monitor and map your network infrastructure with SNMP regardless of your vendor solutions. Get all pre-compiled MIBS with a compiler and comprehensive alerting features.Ĭheck performance and availability of over 70 network services (such as PING, HTTP, LDAP, SQL). Monitor any SNMP devices, including routers, switches, and firewalls. This way, only the network path required for each host to reach the Nagios server need to be open.NetCrunch Solutions Network Devices & Infrastructure Monitoring NSCA sends the results of the check to the Nagios server. Also, use the check_nrpe plugin, not the check_nt plugin, in NSClient++.Ĥ) You may want to consider NSCA instead of NSClient++. You can change the port, but the network traffic path must be clear. Cannot remember the port, but it is not a commonly opened port. For one, NSClient++ requires a specific port to be open on both hosts, on both networks, in both traffic directions. Or simply regular scheduled host checks via ping.ģ) I am not sure if NSClient++ appropriate. Then the normal Nagios monitoring can be done. The IP addresses of each host in the VPN can be static. I could join said channel and view at a glance which machines were connected, and the channel log(with enough sifting) would tell me which machines were frequently disconnecting.Īfter a bit of googling I've arrived at NCclient++ which I've installed on a remote box and am attempting to make check in with my brand-new Nagios box, without much luck.Īm I on the right track? Can anyone point me in the right direction? I've been googling around for a more comprehensive guide on how to do this, and I've not had much luck.ġ) What about using dynamic DNS for each host? The last poll time indicated in the service can be a rough uptime gauge.Ģ) Something equivalent to Logmein Hamachi can create a virtual private network of all the hosts. My original idea was to have a hidden IRCbot launch on each machine and autoconnect to a channel. I'm looking for an open-source/free solution. Would be nice: A simple log for each machine indicating times they went offline. I just want to have a list of the machines, if they are currently connected to the internet, and if they're not connected when did they check in last. These are all behind cheapy consumer level routers of various makes, and they all have dynamic IP addresses. I'm trying to monitor the uptime of 53 remote windows machines, all at separate locations.
