How to reschedule multiple/all services at once

[Jake Xu]

Just attached Andreas' response from another thread.

@Dan, I've taken a look at Multisite. It seems to have some crazy batch
commands/comments which are exactly what I am looking for. I tried it a bit
but ended up getting segfault from apache when I accessed the webpage
localhost/check_mk/. It's probably because I have too many sites running on
my test box. Will try again later. Thanks for the recommendation.

@Michael, Icinga would be good if I started from sratch. It is pain for me
to migrate everything to Icinga though because the default file structure
is different and the web ui is not as straightforward as Nagios core.
Thanks for showing me the OMD, didn't aware of it at all.

@Andreas, I am defining "large number of hosts" as >= one thousand, and
each host is likely to have +/- 10 services, so you get the idea :) I agree
with you that Thruk doesn't look as good as others, so I am looking into
Check_MK Multisite as it has some pretty useful
commands/shortcuts/features. I don't use the report feature that much, so
Multisite should be good enough.  Yeah, hacking the cgi is really
undesirable. I will just try to adapt anohter UI like Multisite.


Thanks for all the response!

YMMV.
