AW: difference between check_by_ssh / check_nrpe

[Schaffranneck, Sven (K-DOI-5/4)]

Hi,

yes, both needs a daemon, both are encrypted (nrpe maybe, because encryption
on hp-ux and aix doesn't work for me) and both starts scripts on the remote
server.

the main difference ist the performance. check_by_ssh is more than poor. it
needs huge amoung of cpu-time couse of ssh, nrpe is very performant.

if you need to check behind firewalls, check_by_ssh is maybe what you want,
because you don't have to open a new port, if you already opened it for ssh.
an other argument is is, that you can connect with different users if you
are using check_by_ssh. so you can check oracle with the oracle-user and
check prozesses with some other user.

everything has its pro's and con's ...
