logrotate - hobbit 🔗 link

For anyone using 'logrotate', the following file will rotate all the hobbit 
logs. 
Create the file as logrotate.cfg: 

# Configuration file for logrotate application
#
# Add the following line to cron:
# 0 8 * * * /usr/sbin/logrotate [hobbit directory]/server/etc/logrotate.cfg 
#

# Global options
compress

/var/log/hobbit/bbcombotest.log {
missingok

/var/log/hobbit/bb-display.log {
missingok
weekly
rotate 5 
}

/var/log/hobbit/bb-retest.log {
missingok
weekly
rotate 5
}

/var/log/hobbit/enadis.log {
missingok
weekly
rotate 5

Great stuff Brian.  Thanks for contributing.

I ran across the following thread when looking up some info on setting up
logrotate (linux) for Hobbit.
I'm curious, though... The man page for hobbitd says that SIGHUP will cause
hobbitd to "Re-read the bb-hosts configuration file."
Does that mean the example below with the postrotate command will actually
work as intended, or will it only have hobbitd re-read the config file?

It does in fact work. SIGHUP triggers both a configfile reload, and a
re-opening of the logfiles.

Hobbit has very good feature that hobbit server accepting message existing bb client.
But is it possible to  code hobbit client to have a mode  to compatible with existing BB server ?
Tear down an existing BB server is not as easy as it seems.

I feel your pain, as we too are migrating our BB server (actually, servers)
into a single Hobbit server.  To add to the complexity, the hobbit server is
on an entirely different subnet (and thus IP) as the BB server, so ACL
changes need to be made as well.

However, considering the many additional features Hobbit has that BB
doesn't, I think in the end it actually makes it easier to manually convert
everything to the Hobbit server syntax.  It also forces you to look in to
some of the additional features in Hobbit.  However, if you aren't so
concerned about using the additional features (except for the trend
graphing), the only thing that should be required to get it working in
"compatibility" mode is just add the hosts on the server to the bb-hosts
file, and repoint the BB clients to the new Hobbit server (and hope ACL
changes aren't also required).

What specifically is slowing you down in your migration?

Two benefits for this request.
1. replace per-seat license bb client with hobbit client to save 
administration overhead(ie, counting number of bb clients and paying the 
license).
2. Avoid the rrd and logfile migration from bb to hobbit.
    one can have both bb and hobbit server up and receiving bb messages. 
once new hobbit server
    contain one year data/logs then bb server can be turn off.

I don't buy that. Converting a BB server to Hobbit requires you to do
two (maybe three) things:

* Move the RRD files around; there's a script included with Hobbit 
  which takes care of that. Takes a few minutes at most.
* Convert your alert configuration from BB to Hobbit. Even for a
  moderately complex alert setup, I would guess you could do it in
  a day or two (can be done in advance).
* Server-side scripts may need a bit of tweaking, but for the most part
  they should work if you enable the compatibility module to save status
  logs and disable-files.

The logfiles are compatible between BB and Hobbit. The bb-hosts file is
backward compatible so you can copy it from BB to Hobbit (not the other
way around). The client configuration is different, but that doesn't
matter when we're discussing the server migration.

So I disagree with your premise that migrating a server from BB to
Hobbit is difficult. It is a lot more difficult to make the Hobbit 
clients compatible with a BB server. E.g. there is no way you can get a
BB server to push the configuration to a Hobbit client without
re-implementing parts of the Hobbit server in the BB network daemon.

But, you could set your BB server up to run a proxy (on the default port) which proxies to your Hobbit server, as well as the real BB server.

Or, if you are running the 4.2 clients, you could use the msgcache feature, so Hobbit polls the clients for their data.

If the issue is the network tests, the proxy solution should work, until you need to remove the server (but, that you would have to do regardless of software).

The problem is, we have 3 different BB servers for several different

but for our purposes, I'm finding it easier to move the hosts individually
to Hobbit.  However, if we get down to only a few hosts left on the BB
servers, we may do just that finish the migration, and deal with the ACLs at
a more convenient time.

We have very restrictive network ACLs, so even that method will require some

Yeah, we also have several network tests, such as connection, smtp, dns,
ftp, etc.
