check_dhcp_snmp

Project Notes

# Perl check for DHCP pools via SNMP bulkwalk. Specifically written to monitor Windows 2012R2 DHCP.
# — Fast. Checks ~1000 scopes in 1.5 seconds.
# — Lightweight. Perl-only. Only two SNMP queries.
# — Defaults to including all scopes, which is most meaningful for ops and NOC.
# — Easy to specify inclusions only. For example, can specify a specific location’s scopes.
# — Allow excluding scopes, such as small test scopes you’d never want alerted on.
# — “Include” trumps the default “all” or any specified “exclude” scopes.
# — Allows defining a backup DHCP server, when primary is under maintenance. Useful when monitoring
# specific scopes.
# — Includes perfdata, disabled by default.
# — Output sorted by criticality -> scope. Any Critical, then Warning, are at the top of the output.
