Mon and pulse (redhat) are two other popular options.

I use both for different things. Each has its strengths and weaknesses and
are capable of doing what you want. I have not used mon or pulse.

. Maybe you can extend the script with sleep commands? This would be the
simplest solution IMO. For example:
*/1 * * * * root /usr/local/sbin/my_lvs_script.sh
my_lvs_script.sh:
command1
command2
command3
Change to:
i=0
while i < 60
command1
command2
command3
i=i+10

In my experience any of the above would be ok. But you really should get a
QA setup, even if its only temporary. By the way, if this is a live setup I
assume you have thought of extending to HA? If so, then a
keepalived/ultramonkey/pulse && HA switch while you are upgrading this
solution might be a good idea.
