bobbeling Posted December 29, 2016 Report Share Posted December 29, 2016 I was reviewing my network with Wireshark and noticed the incredible amount of ARP requests that Domotz outputs. It sends an ARP request to every IP address in my network. I have 2 VLANs that Domotz monitors. Is every 30 seconds really necessary? Looking at my L3 network switch, it looks like my CPU jumps up 10% every 30 seconds. Not a huge impact, but it seems a bit excessive. Anyone else notice this? Is there a way to change the frequency? 2 Quote Link to comment Share on other sites More sharing options...
johnpoz Posted December 30, 2016 Report Share Posted December 30, 2016 The ability to adjust the frequency would be nice.. Quote Link to comment Share on other sites More sharing options...
Tommaso Posted January 5, 2017 Report Share Posted January 5, 2017 Hi all, our scan frequency is currently not customisable: it's part of our core infrastructure and we must pay very close attention to any adjustment. This high rate is needed to send real-time alert. Quote Link to comment Share on other sites More sharing options...
NorthBT Posted January 18, 2017 Report Share Posted January 18, 2017 Hi folks, We are also seeing large amounts of broadcast ARPs - 500 broadcasts over a 1s period, every 30 seconds. Although this may be acceptable to devices with powerful processors, our humbler devices (10Base-T) are getting heavily loaded by this, and our real application messages are getting slowed/lost. Is it not possible to stagger these ARPs, or send unicast to known devices, rather than hitting a network so heavily, so often? We also notice broadcast ARPing to subnet-broadcast address x.x.x.255/24 and x.x.x.0/24? 2 Quote Link to comment Share on other sites More sharing options...
DanielW Posted October 25, 2017 Report Share Posted October 25, 2017 tapping into this. Is there a way to tweak broadcasting or use unicast? I was troubleshooting our network performance an 3.5 million packets a day. happy to sacrifice realtime alers for the network. for the moment turning off domotz 1 Quote Link to comment Share on other sites More sharing options...
