RE: [Devmon] problem getting devmon to work

[Schwimmer, E. E *H. <EE...@hs...>]

Hi Dan,

I *think* the problem that you are having is that you are
running devmon with the --readbbhosts flag;  this flag tells
devmon to read the bbhosts file into the database and then quit,
which I what I think is happening here.

Try running it like this:=20
./devmon -vv -p=20
(the -p flag implies -f as welli, I should probably document that :)

If you've previously run devmon with the --readbbhosts flag, and
devmon has created the hosts.db file in the devmon directory, then it
should read in from that file, poll your hosts, do the logic, and spit
out your message.

The design reasoning behind the --readbbhosts flag, and why I didnt=20
just make devmon read the bbhosts file every poll cycle, is twofold
(you can probably skip reading this, I just like typing):

1) The fact that running a multi-node cluster, you probably  dont want
to run the devmon process on your display machine, but want to farm it
out to dedicated devmon polling servers.  The readbbhosts flag makes=20
it so that you can import your bb-hosts file into the cluster database,
without having to actually run devmon on the display machine.

2) Reading the bb-hosts file and querying the hosts takes a little =
while,
since devmon queries every host in the bb-hosts file, every time (making
no assumptions as to whether hosts that were there during the last=20
auto-discovery are the same hosts that are there on this one;  people=20
have been known to swap out devices with different vendor/models and not
change the bb-hosts ip or hostname).  So I didnt want this =
auto-discovery
phase to interfere with polling times. =20

My devmon is close, but still not working. Here's what I've done:

Made a new template for a cisco 7609, just changed the spec, is about
all - it's just like a 6509.

Put devmon next to the appropriate line in bb-hosts, like this:

<ip>     gsr-east.domain # ssh !telnet DEVMON

Configured my devmon.cfg:

MULTINODE=3DNO
BBHOSTS=3D/home/monitor/server/etc/bb-hosts
BBTAG=3DDEVMON
SNMPCIDS=3Dmycid,public,private
NODENAME=3DHOSTNAME
PIDFILE=3D/var/run/devmon/devmon.pid
LOGFILE=3D/var/log/hobbit/devmon.log
DBHOST=3Dlocalhost
DBNAME=3Ddevmon
DBUSER=3Ddevmon
DBPASS=3Ddevmon
BBTYPE=3Dhobbit
DISPSERV=3Dlocalhost
DISPPORT=3D1984
MSGSIZE=3D8096
MSGSLEEP=3D10
CYCLETIME=3D60
DEADTIME=3D180
CLEARTIME=3D180
NUMFORKS=3D10
MAXPOLLTIME=3D30
SNMPTIMEOUT=3D2
SNMPTRIES=3D5

And run this:

$ sudo -u monitor ./devmon -vvvvv -p -f --readbbhosts
[06-03-01@15:15:32] SNMP querying all hosts in bb-hosts file, please =
wait...
[06-03-01@15:15:32] Querying pre-existing hosts
[06-03-01@15:15:32] Discovered gsr-east.domain as a cisco 7609

And that's all I get. I thought I'd be getting the same messages it's
sending hobbit, but i'm not seeing them.

What am I doing wrong?

Thanks

Dan
