Citrix monitor
Hi list, We have some citrix servers over here we want to monitor.

wrapping long lines in mon.cf, how?
Can long lines in mon.cf be gracefully wrapped, as: hostgroup testing_server_network 172.16.0.1 172.16.0.2 172.16.0.3 \ 172.16.0.4 172.16.0.5 or does this mess things up? ___ mon mailing list mon@linux.kernel.org http://linux.kernel.org/mailman/listinfo/mon
what about spaces in names in mon.cf?
Is this possible in mon.cf: hostgroup "My Server Group" watch "My Server Group" ... ? ___ mon mailing list mon@linux.kernel.org http://linux.kernel.org/mailman/listinfo/mon

Is this possible in mon.cf: hostgroup "My Server Group" watch "My Server Group" ... From the man page: Lines are parsed as they are read. Long lines may be continued by ending them with a backslash ("\"). If a line is continued, then the backslash, the trailing whitespace after the backslash, and the leading whitespace of the following line are removed. The end result is assembled into a single line. Also from the man page: Hostgroup entries begin with the keyword hostgroup, and are followed by a hostgroup tag and one or more hostnames or IP addresses, separated by whitespace. The hostgroup tag must be composed of alphanumeric characters, a dash ("-"), a period ("."), or an underscore ("_"). Non-blank lines following the first hostgroup line are interpreted as more hostnames. The hostgroup definition ends with a blank line. And: Watch entries begin with a line that starts with the keyword watch, followed by whitespace and a single word which normally refers to a pre-defined hostgroup. If the second word is not recognized as a hostgroup tag, a new hostgroup is created whose tag is that word, and that word is its only member. -David David Nolan<*>[EMAIL PROTECTED] curses: May you be forced to grep the termcap of an unclean yacc while a herd of rogue emacs fsck your troff and vgrind your pathalias! ___ mon mailing list mon@linux.kernel.org http://linux.kernel.org/mailman/listinfo/mon
Can "inverval" go inside "period" stanza?
Can "interval" go inside a "period" stanza - I need to run tests at different rates, depending upon time of day and day of week. For example: service mytest description My_Test monitor my_test.monitor ;; period wd {Mon-Fri} hr {00:00:00-03:59:59} interval 300s alertevery 10m alertafter 1 alert mail.alert [EMAIL PROTECTED] period wd {Mon-Fri} hr {04:00:00-22:59:59} interval 20s alertevery 10m alertafter 1 alert mail.alert [EMAIL PROTECTED] period wd {Mon-Fri} hr {23:00:00-23:59:59} interval 300s alertevery 10m alertafter 1 alert mail.alert [EMAIL PROTECTED] period wd {Sat-Sun} hr {00:00:00-23:59:59} interval 300s alertevery 10m alertafter 1 alert mail.alert [EMAIL PROTECTED] ___ mon mailing list mon@linux.kernel.org http://linux.kernel.org/mailman/listinfo/mon

For example: no, it can't, but that wouldn't be a difficult feature to add. ___ mon mailing list mon@linux.kernel.org http://linux.kernel.org/mailman/listinfo/mon
