Question about Server Status Forwarding

11 messages in this thread

list David Morgan · Mon, 10 May 2010 09:39:22 -0400 · 
We are starting to deploy multiple "collector" servers.  What we want
is to have Hobbit Server A collect from it's local group, Server B to
collect from its local group, and Server C to collect for its local
group.  (By local group, I mean IP address and physical location
space).

Then we want to have Server A and Server C send the status messages
that they have collected to Server B.

I THOUGHT all that needed to be done was to put in the following:

[snip from hobbitserver.cfg on Server A]

BBDISP="0.0.0.0"                # IP of a single hobbit/bbd server
BBDISPLAYS="<Server A IP>,<Server B IP>"          # IP of multiple
hobbit/bbd servers. If used, BBDISP must be 0.0.0.0

However, it appears that all the entries that are being forwarded are
coming in as ghosts.  Is there something else I need to do on ServerB?
 Or on the client side?  Should I be using BB-proxy?  There isn't any
firewall or proxying between the groups.

If they are coming up as ghosts, then you need to make sure there is an
entry in your bb-hosts file with the same hostname as being reported in
the ghost report or a CLIENT tag on the bb-hosts line you have for this
server.

Not sure what else to check.  I tried restarting the hobbit/xymon service, but still have the ghost entries.

It LOOKS like it is the local systems that are reporting into Server B
are most of the ghost clients.  Not sure if there is something on that
system that I should also set.

Then we want to have Server A and Server C send the status messages

I THOUGHT all that needed to be done was to put in the following:

[snip from hobbitserver.cfg on Server A]

BBDISP="0.0.0.0"                # IP of a single hobbit/bbd server
BBDISPLAYS="<Server A IP>,<Server B IP>"          # IP of multiple
hobbit/bbd servers. If used, BBDISP must be 0.0.0.0
These settings are of interest to client parts of xymon, in other words, components which run tests from this server (such as the bbnet task, the local client etc.), and send data to hobbitd. This does not result in hobbitd on ServerA sending any data it receives (e.g. from clients) to any of these IP addresses (ServerB).

Please see the coverage of this variable in 'man hobbitserver.cfg'.
▸ quoted from Bruce White
However, it appears that all the entries that are being forwarded are
coming in as ghosts.  Is there something else I need to do on ServerB?
ServerB needs to have entries in its bb-hosts file for all the hosts being monitored by ServerA and ServerC. You probably want to make use of the NET tag, and set BBLOCATION accordingly on each of the Xymon servers, so that the correct servers test the correct hosts, while only needing to maintain a single bb-hosts file (which should be kept in sync across all 3 servers).

 Or on the client side?  Should I be using BB-proxy?
Between these two options, I would use bb-proxy, so that client data sent by monitored hosts is relayed to your central server. However, if you want to have the extra maintenance overhead in return for still receiving client data in case of a failure of the monitoring server, you could set BBDISPLAYS on all the clients.

To assist in resolving this further, you may want to include some more relevant information. For example, follow a host monitored by ServerA, provide:

The entry in ServerA's bb-hosts for this host
The entry in ServerB's bb-hosts for this host
The BBDISP/BBDISPLAYS value from this host's client config
The bbproxy task from ServerA if relevant

Buchan

I think I have it fixed.  We had a number of mis-configured clients,
so that is what was causing the screwey behavior.  I rebuilt the
servers and the bb-host files from scratch and have verified that the
servers are checking into the right xymon server.

Will update the thread once I have gotten the forwarding done.
