We have some low-end and/or old Cisco devices which do not support in snmp all information that we needed. For example 'ip local pool' utilization can be done through SNMP only for 72xx/73xx with IOS 12.4. In our current monitoring system we get this information through rsh-script. Is there any way to use this script as data source for custom poller, or any way to insert data information from script to appropriate SQL database table?
