powershell script to find available dhcp scope

Unfortunately it meant I couldn't use that workaround anymore. However, I had to install some Health Agents which have a dependency on the SNMP service. I've been using the workaround from SwissJay for a while.

$result +='LeaseDuration '+$ScopeInfo.LeaseDuration+'' $result +='ReservedAddressCustomIPAbsolute110'+$ScopeStats.ReservedAddress+'' $result +='AddressesFreeCustomIPAbsolute110'+$ScopeStats.AddressesFree+'' $result +='AddressesInUseCustomIPAbsolute110'+$ScopeStats.AddressesInUse+'' $result ='PercentageInUsePercentAbsolute1101'+$ScopeStats.PercentageInUse+'9075Attention 75% des adresse IP affectes !Attention 90% des adresse IP affectes !1' $ScopeReserved =$ScopeStats.ReservedAddress $ScopeStats = Get-DhcpServerv4ScopeStatistics -ComputerName $Server -ScopeId $Scope | Select ScopeID,AddressesFree,AddressesInUse,PercentageInUse,ReservedAddress $ScopeInfo = Get-DhcpServerv4Scope -ComputerName $Server -ScopeId $Scope

$ScopeList = Get-DhcpServerv4Scope -ComputerName $Server $scope = Get-DhcpServerv4Scope -ComputerName $server Put this code as 'dhcpprtg.ps1' in the EXE/XML folder. If you want you can use the following powershell script (which is not deprecated on 2012 server) with an advanced exe/script sensor. If you wish to monitor DHCP using powershell instead, there are several customer-shared scripts available, pick the one that suits you best:.If you encounter Generic Error (SNMP error # 5) on Windows Server 2012, please refer to this.Since the data is a SNMP Table, this is a great opportunity to try-out the SNMP Custom Table sensor.Ex.: Set a notification to send an email/sms if the number of available IPs are below 10.Įdited by Mod, thanks for the contribution. Then You can add notifications and thresholds per sensor. Example, if your scope is 192.168.100.0 and you want to know the number of used IP's, the complete OID will look like this: 1.3.6.1.4.1.311.1.3.2.1.1.2. Add a PRTG SNMP Custom or SNMP Custom Advanced Sensor with the MIB value required, and make sure you modify the SNMP credentials. Check the available OID's in the DHCP-MIB You will find all the relevant MIB values related to the DHCP scope statistics: dhcpScopeġ.3.6.1.4.1.311.1.3.2.1.1.1. Specify the community name and hosts allowed to get snmp info.ģ. Once the snmp service is installed, click on it, then click on the security tab. Then go to Network and management tools and install the service.Ģ. Install the snmp service in your DHCP server if not installed, using add/remove windows components. Monitor DHCP statistics, using DHCP MIB and PRTG SNMP-Custom sensors. Here is a way to monitor DHCP statistics per scope: Summary
