Re: [ovirt-users] Changing the engine HA ping address?
Once upon a time, Chris Adams <cma(a)cmadams.net> said:
The gateway IP is a layer-3 switch, and I think sometimes it just is
not
responding to ICMP echo request in a timely fashion (traffic is routing
just fine though). How is the HA ping implemented? How many requests
does it send (and how many responses are required to be considered
"good")?
I see ovirt_hosted_engine_he/broker/submonitors/ping.py that only one
packet is sent. That's probably not a great way to do things; there are
a number of routers/firewalls/etc. that put ICMP echo requests to the
device (as opposed to through the device) at the very lowest priority,
and drop them under any load.
A better way would be to send multiple requests, with only one answer
required. "ping -c 1 -i 0.2 -w <timeout> -W <timeout> <IP>"
should do
that.
