New candidate release of 1.0.1
Carlos Vicente (5):
Fixed issues that affected Debian Squeeze installation
Fix for #1644. Changed Nagios notification command names to match names
in Nagios package
Updates to the user manual
Improved installation a bit. Debian-based systems should not need to use
snmp-mibs-downloader, since the netdisco-mibs should suffice. The only missing
piece was pointing to the right place from snmp.conf
Minor changes to manual

Issue #1645 has been updated by Carlos Vicente.
Hi Emmanuel,
This idea poses some challenges. Netdot polls ARP tables every hour by default,
but this could be changed in the cron job. Also, the removal of IP addresses
that haven't been seen for a while is done by a cron job which the
administrator can also change. It could be every day, or every week, every 3
months, etc.
If your DHCP leases are shorter than the period at which the IP addresses are
removed, then Netdot will be giving you wrong information: the IP address could
be available in DHCP, but Netdot would still show it as used.
What we do at the University is to graph the utilization of DHCP pools using
SNMP. This process polls the DHCP servers every 5 minutes and determines more
exactly how many addresses are used in the pool. This requires some special
scripts and configurations, which I'd be glad to share outside this ticket.

Feature #1645: Dynamic IPs in use
https://osl.uoregon.edu/redmine/issues/1645
Author: Emmanuel Togo
Status: New
Priority: Normal
Assignee:
Category:
Target version:
Resolution:
To be able to easily determine actual number of IPs in use from dhcp scope.
This I believe will help administrators know whether they are running out of IP
address space for a particular DHCP scope.
my suggestion is to color dynamic IPs in use just as is done for the discovered
IPs
