NOCOL/SNIPS is a system and network monitoring software that runs on Unix systems and can poll network and system devices. It is capable of monitoring nameservers, web ports, host performance, syslogs, radius servers, BGP peers, etc. New monitors can be added easily (via a C or Perl API).
All monitors have a common display and postprocessing interface (logging, notification, etc.) This design allows running only one set of monitors and any number of displays each seeing the same consistent data.
False alarms are avoided by escalating events through severity levels- hence if a site is unreachable, the site will be test 2 more times before finally indicating that it is 'critical'. All events are logged, and the operator has the capability to decide which level to view the events at.
Available monitors are:
| ICMP ping | RPC portmapper | OSI ping | |
| Ethernet load | TCP ports | Nameserver | |
| Radius server | Syslog messages | Mailq | |
| NTP | UPS (APC) battery | Unix host perf | |
| BGP peers | SNMP variables | Data throughput |
The software is available from http://www.netplex-tech.com/software/nocol or via ftp from ftp.navya.com.
