[hobbit] How do I clone maintenance mode record ?

[Ralph Mitchell]

I think maybe the server keeps the disabled status in memory, so simply
copying files just isn't going to do it.  This should do the trick:
===== server/ext/getblues.sh =====
      #!/bin/bash

      . /home/xymon/server/etc/hobbitserver.cfg

      $BB localhost "hobbitdboard color=blue
fields=hostname,testname,disabletime,dismsg" | $SED -e 's/\\/\\\\/g'
===== end of file =====

===== server/ext/putblues.sh =====
       #!/bin/bash

       . /home/xymon/server/etc/hobbitserver.cfg

       cat $1 | while read line
       do
          OFS="$IFS"
          IFS="|"
          set $line
          IFS="$OFS"
          x=`echo "$4" | $SED -e 's/\\\n/\n/g'`
          $BB localhost "disable $1.$2 $3 $x"
       done
===== end of file =====

1) on the primary, whenever the other files are copied, run this and copy
the file:

      server/ext/getblues.sh > server/tmp/blues.out

2) whenever the secondary needs to take over, have it run the other script:

     server/etc/putblues.sh server/tmp/blues.out

That should load up the disabled status messages into the secondary.

NB: I've only tested this on a single server, making a slight change to the
messages in the blues.out file before reloading it.  The change loads up
just fine, so it would *probably* work on a different server.  YMMV  :)
