DHCP hands out addresses on request. These addresses have a lease lifetime and the device that requested the address will be required to renew prior to the expiration of the lease. There is no guarantee that the device will always receive the same IP address, although it is very likely. Further problems arise when devices with an allocated address leave the network - a cell phone on WiFi, for example, will travel away from the network and therefore the address is no longer active or may be reassigned to a different device. This will generate graphs with holes, spikes and all kinds of noisy information. Assuming you're going to continue down this path, you'll need to find the dhcpd.leases file on your DHCP server. In a Linux installation, the file is normally located at /var/lib/dhcp3/dhcpd.leases. You'll then need to write a script to read this file, extract IP addresses, generate a set of Smokeping targets in your smokeping configuration file and finally reload Smokeping. You may also want to remove targets from leases that are no longer active, or not... Bandwidth measurement is not a strength of Smokeping. As mentioned by Paul Mansfield, you will want to use a different solution that can read SNMP information from your managed switch to retrieve the number of packets being sent and received.

Now you can install local copies of the missing modules by running ./setup/build-perl-modules.sh /opt/smokeping/thirdparty The RRDs perl module is part of RRDtool. Either use the rrdtool package provided by your OS or install rrdtool from source.

If you have that many hosts you must be using some sort of automated deployment and monitoring already so you can get the list of IPs from that. ------------------------------ Message: 7 Date: Mon, 8 Jul 2013 11:27:30 +0100 From: Paul Mansfield <[email protected]> Subject: Re: [smokeping-users] (no subject) To: [email protected] Message-ID: <cahyek0f+pa9jpeapnwifeqd3gqr+ytktqcaacd8ynjvq6rm...@mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 Simply emailing me directly with your original question, without having considered my reply, is neither polite nor likely to yield results.
