Graphing Address Utilization
The DHCPatriot also allows the graphing of address utilization on some graphing
system such as Cacti. The OIDs necessary are detailed in the table below.
IP Address Utilization
OID: 1.3.6.1.4.1.2021.50.60.3.0.<gateway address of Main DHCP Range>
Example: 1.3.6.1.4.1.2021.50.60.3.0.208.45.199.113
This OID will return a measurement of the total number of IP addresses in use on a
particular dynamic subnet in the most recent five minute interval. This is the same
measurement used to compute the dynamic graphs in IP Address Usage (see section
4.2.10).
Additionally, there are more advanced options for retrieving data about subnets and
totals of dynamic networks. These options allow the listing of data sources as well as
data retrieval.
Per Subnet data
• 1.3.6.1.4.1.2021.50.80.1 will list all available dynamic subnets for which used and
available data may be retrieved
• 1.3.6.1.4.1.2021.50.90.1.(gateway address result from 1.3.6.1.4.1.2021.50.80.1) will
retrieve used IP address number from the chosen subnet
• 1.3.6.1.4.1.2021.50.100.1.(gateway address result from 1.3.6.1.4.1.2021.50.80.1)
will retrieve total available IP address number from the chosen subnet
For example:
This command will list all available subnets for per subnet graphs:
snmpwalk -On -v 1 -c lnx-snmp patriot-1.network1.net 1.3.6.1.4.1.2021.50.80.1
Output would look something like this:
1.3.6.1.4.1.2021.50.80.1.1 = STRING: "
10.31.128.1
"
1.3.6.1.4.1.2021.50.80.1.2 = STRING: "10.69.254.1"
1.3.6.1.4.1.2021.50.80.1.3 = STRING: "172.16.254.1"
1.3.6.1.4.1.2021.50.80.1.4 = STRING: "208.45.199.113"
1.3.6.1.4.1.2021.50.80.1.5 = STRING: "10.31.128.1"
1.3.6.1.4.1.2021.50.80.1.6 = STRING: "10.69.254.1"
1.3.6.1.4.1.2021.50.80.1.7 = STRING: "172.16.254.1"
1.3.6.1.4.1.2021.50.80.1.8 = STRING: "208.45.199.113"
1.3.6.1.4.1.2021.50.80.1.8 = STRING: "208.45.199.113"
Error: OID not increasing: 1.3.6.1.4.1.2021.50.80.1.8
>= 1.3.6.1.4.1.2021.50.80.1.8
