Hi Henrik/Ralph,
On my system running 4.2 with all in one patch...
./server/bin/bb 10.1.50.4 ghostlist
bar|10.1.50.4|1211944491
ho|10.1.50.4|1211944491
hum|10.1.50.4|1211944491
zulu.XXXX.com.au|10.1.50.4|1211944491
So all the above is good....
Just to clarify, hosts bar, ho, hum and zulu are all sending a message to
hobbitd every five minutes. Only one test is being sent, this is a test
titled alerts. There is no cpu, memory or any other test being sent.
And just to confirm,
grep zulu ./server/etc/bb-hosts
returns nothing...
I then add the following line to bb-hosts
0.0.0.0 zulu.XXXX.com.au
grep zulu ./server/etc/bb-hosts now returns
0.0.0.0 zulu.XXXX.com.au
I now wait >10 minutes (only because I am trying to multi-task other
work)... The host appears on the bb.html page and I can see a yellow dot for
the test that is being sent every five minutes to trigger it as a ghost... I
can click on the dot and see the message, including an rrd graph of the data
received. So far so good...
I now run...
./server/bin/bb 10.1.50.4 hobbitdboard | grep zulu
zulu.XXXX.com.au|trends|green||0|0|0|0|0||0|
zulu.XXXX.com.au|info|green||0|0|0|0|0||0|
zulu.XXXX.com.au|conn|green|OrdAstLe|1211945995|1211946296|1211948096|0|0|
10.1.50.4|-1|green <!-- [flags:OrdAstLe] --> Wed May 28 11:44:55 2008 conn
ok
zulu.XXXX.com.au|alerts|yellow||1211945994|1211946295|1211948095|0|0|
10.1.50.4|82688|yellow Wed May 28 11:44:55 WST 2008
So from the above, I would assume that it would now no longer be listed as a
ghost...
Just to be sure, I will wait another >15 minutes....
And then...
./server/bin/bb 10.1.50.4 ghostlist
bar|10.1.50.4|1211946596
ho|10.1.50.4|1211946596
hum|10.1.50.4|1211946596
zulu.XXXX.com.au|10.1.50.4|1211945699
It is still there...
I give it another 10 minutes and then I restart hobbit
su - hobbit -c "/opt/hobbit/server/hobbit.sh restart"
wait 10 minutes...
And re-run
./server/bin/bb 10.1.50.4 ghostlist
bar|10.1.50.4|1211947632
ho|10.1.50.4|1211947632
hum|10.1.50.4|1211947632
zulu has gone...
This email is long enough, but if I now reverse the process and remove zulu
from the bb-hosts file, zulu will never become a ghost again until after the
next restart, even though hobbitdboard no longer shows it in its list.
Can I assume this is a bug/feature?
Cheers
Phil

I am trying to use the output received from hobbitd when issuing the bb
ghostlist command. The command reports correctly, but after modifying
the
bb-hosts file, ghostlist continues to report ghosts. I need to do a full
restart of hobbit to get hobbitd reporting correctly.
hobbitd reloads the bb-hosts file every 10 minutes, or if you send a HUP
signal to the hobbitd process. Hosts will remain on the ghostlist until
no reports have been received with ghost hostname for 10 minutes.
So if you have a ghost reporting at 12:00, and you modify the bb-hosts
file at 12:01, then the host reports again at 12:05, the bb-hosts file
is reloaded at 12:11, and the ghost entry expires at 12:15. So it may
take up to 15 minutes before the ghostlist entry disappears.
I started digging through the source tonight but I have to admit that I
just
can't understand C well enough. hobbitd knows the bb-hosts file has been
updated because the host appears on the webpage, but ghostlist still
reports
it incorrectly.
Note: the fact that the host appears on the webpage does NOT mean
hobbitd knows about it. The webpage is generated by another task, and
until hobbitd learns about the new hostname, it will just show up
with no status columns.
I did this just one time:
server/bin/bb localhost "status server,domain,com.bogus green `date`"
server.domain.com has never have existed in my bb-hosts file. It showed
up in the Ghost Clients web page for 5 minutes. It also showed up in the
ghostlist generated via this command:
server/bin/bb localhost ghostlist
Several days later, the above command was still showing this:
server.domain.com|127.0.0.1|1211218983
This was with the Jan 25 2008 4.3.0 snapshot.
