[Xymon] Xymon Network Tests - Behaviour?

[Mario Valetti]

Hi,

Could someone please explain the exact behaviour when a host becomes
unreachable?

As I understand it, it works as follows...

- Xymon pings each host only once,
- if a reply is not received within a specified time (1sec), 3 ping
requests are sent out,
- from one of these three additional pings if a reply is received, the
host is not indicated as being unavailable and things continue
normally.  If a reply is not received from these three additional
requests, the host is marked as unavailable and four pings requests
sent out every minute until a response is received.

- Why do hosts show unavailable for 40s, 45s for example?  Are the
times above not fixed and rather work dynamically?


Second question is regarding hosts that are shutdown for maintenance,
for example...
Usually, these are set to 'until ok' and the host marked blue with no
alerts.  However Xymon still sends an arp request / ping to check when
the host becomes available.

Is it possible to disable a host in a way that avoids Xymon checking
for the host at all?


Thanks,
Mario
