[Xymon] delayred on conn

[Root, Paul T]

Ok, this time it looks like it's working:

$ iptables -I INPUT 1 -p icmp -s 10.5.130.117 -j REJECT --reject-with icmp-host-prohibited
$ date
Fri Mar 18 16:52:57 CDT 2016

Then on the server:

Fri Mar 18 16:55:44 2016 yellow 0:01:11
Fri Mar 18 16:47:12 2016 green 0:08:32

So I’m guessing it should change red at 17:01:57 or so.


Yes, it did:

Fri Mar 18 17:04:45 2016 red 0:00:20
Fri Mar 18 16:55:44 2016 yellow 0:09:01
Fri Mar 18 16:47:12 2016 green 0:08:32


However, it also meant that it paged out immediately, not waiting 5 minutes after it turned red from yellow.

It didn't work for me. Pretty weird though.

I started with this:

10.5.136.247    wilee                   # ntp delayred=conn:9

Then, put in a rule in iptables to block pings. It went red immediately.

And paged after 5 minutes, as my alerts tells it.

Then the weird thing happened. It changed to yellow.

Hold on, I’m going to test again. I bet hosts.cfg hadn't been re-read yet. So it's probably an invalid test.

BTW, 4.3.21 on the server and client.

I'll reply again in 15 minutes or so.

Ohhhh. I think I see something interesting.

In xymond.c, I see the following comment:

My test case was to change a noconn tag on a host to conn. Which meant I
went from clear/no-state to red. I haven't read the rest of that code,
but I suspect my test would be valid only if starting from a green state.
