stand-by hobbit 🔗 link

First, many thanks for creating and maintaning Hobbit, a first-class product !!!
Got a question about running a stand-by (or secondary) hobbit server,
let say, I'm not ready/prepare to run a linux cluster, and would like a
backup server, just in case the primary server, serverA, is down
(due to failure or maintenance).

So, I could just change serverB ip addr and name and reboot to become
the parimary.

hobbit-clients  BBDISPLAY="1.2.3.4"

hobbit-serverA   (1.2.3.4)
BBSERVERIP="1.2.3.4"
BBPROXY="5.6.7.8"
 hobbit-serverB   (5.6.7.8)
BBSERVERIP="5.6.7.8"

why don't you set up two hobbits servers (with perhaps an rsync script 
to synchronize automatically the conf) ?

you'll have two hobbit servers running in the same time (which can lead 
to duplicate alerts, but it's sometimes better to
be alerted two times).

I use a hobbit client on a linux server, but for some reason it doesn't make sense to monitor the memory usage.
I can't seem to find a way not to monitore one of the "base" tests of the linux hobbit client, like memory for instance. I could use a "group-except" in the bb-host file, but I don't like the idea of the memory being monitored but not displayed, I'd really like it not to be tested at all.
Any idea how to do this ?

Hi,

how about putting a '--ignorecolumns=memory' in hobbitserver.cfg
BBGENOPTS="--recent-gifs ....  --ignorecolumns=memory"
It's around line 224

That's what I'm doing currently. Getting rid of alerts is simple, just
disable the hobbitd_alert module on one of the servers. Should that
server fail, you can quickly enable it on the backup server.

  Just to clarify:
1. rsync is run every 5 minutes [your opinion on frequency and other method].
2. the stand-by is running hobbitd normally(?), so only update data, and 
      server/www directories? (what about server/etc)
