Server side EXT script not running or appearing on web page
Hi,
I'm trying to replace the inbuilt SSH test with one that does something intelligent and have put this into ~hobbit/server/ext:
hobbit% cat server/ext/NGssh #!/bin/sh
BBHTAG=NGssh # What we put in bb-hosts to trigger this test COLUMN=NGssh # Name of the column, often same as tag in bb-hosts
$BBHOME/bin/bbhostgrep $BBHTAG | while read L do set $L # To get one line of output from bbhostgrep
HOSTIP="$1"
MACHINEDOTS="$2"
MACHINE=echo $2 | $SED -e's/\./,/g'
MSG="$BBHTAG status for host $MACHINEDOTS"
reply = ssh $MACHINE -l hobbit /usr/ucb/whoami
if [ "$reply" = "hobbit" ]
COLOR=green
else
COLOR=red
fi
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR date
${MSG}
"
done
exit 0
Then the script is added to bb-hosts:
hobbit% grep NGssh ~hobbit/server/etc/bb-hosts group-only conn|cpu|disk|info|memory|msgs|procs|NGssh|trends Campus 123.123.5.52 hostert # noping NGssh 123.123.1.12 hostick # noping NGssh 123.123.16.9 hostker # noping NGssh 123.123.3.11 hostel # noping NGssh 123.123.8.8 hostay # noping NGssh 123.123.5.49 hostmis # noping NGssh 123.123.3.17 hosteus # noping NGssh 123.123.1.11 hosty # noping NGssh 123.123.9.13 hostger # noping NGssh
What else needs to be done to action this script? The script doesn't seem to be running and nothing is appearing in a column. Scripts from the deadcat site mention a BBEXT variable but it's not in any of the hobbit config files.

You shouldn't add external tests to bb-hosts. You add them to etc/bb-bbexttab.
-Dan
$ head -30 etc/bb-bbexttab
bb-bbexttab: configuration file for launching external scripts
Format:
host: misc settings : external scripts list
localhost: misc settings : external scripts list
: misc settings : external scripts list
host can be FQDN (fully qualified domain name) or
just a plain hostname but it is preferred that you
use a FQDN.
localhost: using this specifies that the scripts
specified on the line are to be launched on all clients
The same host can be specified on multiple lines to aid readability
Misc settings field is unimplemented ...
For future use...
You can override the default sleep between cycles
by addding a time qualifier to the script:
e.g.: localhost: script1;600
**NOTE** The sleep delimiter in BBEXT of bbdef.sh was
':' (script1:600) but here it is ';'
in order to keep the same format as the
other bb-*tab files (the : is used to delimit
file entry fields in all bb-*tab files) .
The time qualifier is specified in SECONDS

I originally looked at that, I've since concluded it's dodgy documentation in that it's not specific or complete. The first bit is for client side, the server-side bit lacks the final steps.
Cheers, Mark
Here's how to do it:
In ~/server/etc/hobbitlaunch.cfg add:
[NGssh] ENVFILE /home/hobbit/server/etc/hobbitserver.cfg NEEDS hobbitd CMD $BBHOME/ext/NGssh.sh LOGFILE $BBSERVERLOGS/NGssh.log INTERVAL 5m
In ~/server/ext/NGssh.sh add:
#!/bin/sh
BBHTAG=NGssh # What we put in bb-hosts to trigger this test
COLUMN=NGssh # Name of the column, often same as tag in bb-hosts
$BBHOME/bin/bbhostgrep $BBHTAG | while read L
do
set $L # To get one line of output from bbhostgrep
HOSTIP="$1"
MACHINEDOTS="$2"
MACHINE=echo $2 | $SED -e's/\./,/g'
MSG="$BBHTAG status for host $MACHINEDOTS"
reply=ssh $MACHINE -l hobbit /usr/ucb/whoami
if [ "$reply" = "hobbit" ]
then
COLOR=green
else
COLOR=red
fi
$BB $BBDISP "status $MACHINE.$COLUMN $COLOR date
${MSG}
"
done
exit 0
In your ~/server/etc/bb-hosts add:
group-only conn|cpu|disk|info|memory|msgs|procs|NGssh|trends Campus 123.123.5.52 hostert # noping NGssh 123.123.1.12 hostick # noping NGssh 123.123.16.9 hostker # noping NGssh 123.123.3.11 hostel # noping NGssh 123.123.8.8 hostay # noping NGssh 123.123.5.49 hostmis # noping NGssh 123.123.3.17 hosteus # noping NGssh 123.123.1.11 hosty # noping NGssh 123.123.9.13 hostger # noping NGssh
