Flapping Status
list David Raymond
Hi all, I don't know if you share the same idea as me, but could we add "Flapping Status" as an option in xymonserver.cfg ? We can set it as "yes or no" or other setting, or simply add a flappingstatus.cfg and add system that we want to manage. It is possible ? Keep going good work.
list Sebastian Auriol
The most flexible option would be to specify for each hostname.test what the flapping settings should be. Wilcards and macros could be useful for things like conn flapping, but for custom tests, these ideally want their own flapping settings. I have a custom test that I would want to lock flapping colour for a maximum of 5 minutes as the test runs every minute...

hello all, the last 4-5 days, i have a major problem with my xymon server. I run it for several years, monitoring connectivity on misc servers on my local network. Xymon server is connected to my local network via a VPN, and it seems that the problem is with the computers that have a private ip (10.xx.xx.xx). when i restart xymon, everything seems ok for a few minutes. after this, all become red and i have a "flapping status" warning. i tried to change values in tasks.cfg with no result. i unistalled/installed xymon, with no result. my configuration is very close to the default, except hosts.cfg of course. i tried to ping for hours a host on my localnet, from xymon server, successfully, with no packet lost.. can anyone help me with this ? -- regards, Metron 6 (six) user-17e4b93d552a@xymon.invalid

This could be a number of things. The obvious question is what has changed (that you can see)? Any new routers, changes to the VPN setup? What tests are showing red/flapping? Are all tests for these affected hosts red/flapping? You say it is only those systems with a private network, do you have others that aren't a private network through the same VPN that are OK? What is happening at the VPN gateways at each end, can you run tcpdump on these systems to find any patterns? If tests are flapping, that means some packets are getting through, you should be able to see this on the gateways. hope this helps, Phil

Are you running the ping test from multiple xymon servers? I do that, my main server is on one network, and I have 2 hybrid proxy/backup servers on the more protected network. Where is the NAT going on for this machine? Could it be a DNS issue? Have you tried “testip” in hosts.cfg?
