Alert if a list of devices that are not related are all down?

I would like to have XYMON:

                E.G.  All printers are down at the same time - ALERT

                          All printers just came back up at the same
time - NOTIFY/ALERT

 
I need to watch multiple printers in a building to see if they are ALL
down (or come up) at the same time.

This is the makings of a POWER OUTAGE EVENT for that building since the
printers are not attached to a UPS.

If all down, Possible Power Outage

 
I know that the 'route:' can watch a path to a device and make the
devices behind the down devices go YELLOW 

and the first device in the path go RED.  I don't think that this would
work for this type of alerting.

 
I think this will require some sort of SCRIPT in the hobbit-alerts.cfg
that is executed if any of the printers do not answer a ping.

I have never written a SCRIPT for XYMON but am eager to learn.

In this case the first printer that goes down, calls the script and the
script would have to check if all the other printers are down.

If I have a printer go down and it calls a bash shell script, is there a
way to see if all the rest of the printers are down.

If not, do not alert

If all down, alert

 
I would also need to go the other way:  if a printer comes up
(RECOVERED) are all the other printers up?

This one is more tricky as you have to see when all the other printers
came up.

It would be a false alarm if a single printer went down and then came
back up because you cannot just check to see if all the other printers
are up.

EXAMPLE:  The rest of the printers may have been up and that would not
be a POSSIBLE POWER EVENT.  You must be able to see when the other
printers came up last.

 
The other alternative would be to use my scripts (running on the XYMON
server) to watch the printers and then allow the scripts to trigger a
RED/GREEN event.

I have read where this can be done, but I have not found a good clear
example of creating diamonds and icons for special purposes.

This RED/GREEN event would then trigger the alerting from XYMON.

Again, I have not found a good HOW-TO on setting up additional
devices/diamonds for this purpose.

 
Thanks,

Assuming you have some way of easily identifying your printers
- e.g. they are all on the same webpage in the Xymon display, or
they have some sort of standard name - then you can use the
'hobbitdboard' command to check the status of all of them at 
once.

E.g. if you have all the printers on a page called "printers",
then this would tell you if they were all down:

   #!/bin/sh

   # Grab "conn" status of all systems on "printers" page
   # Only pick the red and green ones, so we ignore those that
   # have been disabled.
   $BB $BBDISP "hobbitdboard page=printers color=red,green test=conn fields=hostname,color" >/tmp/printstatus.$$
   PRINTERCOUNT=`wc -l /tmp/printstatus.$$`
   DOWNCOUNT=`grep '^|red$' /tmp/printstatus.$$ | wc -l`

   if test $PRINTERCOUNT = $DOWNCOUNT
   then
      echo "All printers down!"
   fi

What I would do is feed the information from this script back into
Xymon as a new status - one that shows red if all printers are down,
and green if at least one of them is up. Then you can trigger the
alert from this status, instead of mucking about with the alert
scripts for each of the printers. So you could modify the script
above to become a Xymon server-side extension:

   #!/bin/sh

   # ... beginning is the same ...

   if test $PRINTERCOUNT = $DOWNCOUNT
   then
       # All printers are down
       $BB $BBDISP "status whitehouse.power red `date`
                    Possible power-loss at 1600 Pennsylvania Av"
   else
       # At least one printer is up
       $BB $BBDISP "status whitehouse.power green `date`
                   Power OK"
   fi


And then setup an alert that goes off when the "power" status for
host "whitehouse" goes red.

You'd run the script from hobbitlaunch.cfg every so often, e.g.
to run it every 5 minutes add 
   [powercheck]
       CMD $BBHOME/ext/powercheck.sh
       INTERVAL 5m
to hobbitlaunch.cfg


If you must check if the change for each printer happened "recently"
(e.g. within the past 5 minutes which is the default network test
frequency), then you can add "lastchange" to the list of the fields
retrieved in the hobbitdboard command. That will give you the Unix
timestamp when the status last changed; you can then have the script
compare that to the current timestamp and do whatever appropriate if
the change happened more or less recently. (The GNU 'date' utility 
can give you the current timestamp with "date +%s").


Hope this gives you some inspiration to put this together.


Regards,
Henrik

BB = the path to your hobbit binaries + the bb binary itself. (i.e. /hobbit/server/bin/bb).

BBDISP = the IP address or name (if you have dns running) of your BBDISPLAY server.  If everything is on the same machine, you can use the loopback address.

They're set by hobbitlaunch when it runs the script. For testing,
set them by running the "bbcmd" utility - this gives you a new
sub-shell with all of the Xymon environment setup.

BB is <where-you-installed-xymon>/server/bin/bb

Thanks Bruce I've got the data.
Is the time in seconds since Jan 1, 1970 or some other calculation?
Is there a utility with Xymon to convert it to date and time?

There are three entries in the file for each device on the page=PW:  part of /tmp/PW file
		Printer070|green|0
		Printer070|green|0
		Printer070|green|1254781165

		Printer087|green|0
		Printer087|green|0
		Printer087|green|1254781165

Here is the command I used:
/home/xymon/server/bin/bb 127.0.0.1 "hobbitdboard page=PW color=red,green,lastchange fields=hostname,color,lastchange" >/tmp/PW


P.S.  Is there a location with all the fields you can request?

Thanks

       # All printers are down
       $BB $BBDISP "status whitehouse.power red `date`
                    Possible power-loss at 1600 Pennsylvania Av"
   else
       # At least one printer is up
       $BB $BBDISP "status whitehouse.power green `date`
                   Power OK"
   fi


And then setup an alert that goes off when the "power" status for
host "whitehouse" goes red.

You'd run the script from hobbitlaunch.cfg every so often, e.g.
to run it every 5 minutes add 
   [powercheck]
       CMD $BBHOME/ext/powercheck.sh
       INTERVAL 5m
to hobbitlaunch.cfg


If you must check if the change for each printer happened "recently"
(e.g. within the past 5 minutes which is the default network test
frequency), then you can add "lastchange" to the list of the fields
retrieved in the hobbitdboard command. That will give you the Unix
timestamp when the status last changed; you can then have the script
compare that to the current timestamp and do whatever appropriate if
the change happened more or less recently. (The GNU 'date' utility 
can give you the current timestamp with "date +%s").


Hope this gives you some inspiration to put this together.


Regards,
Henrik

Thanks Bruce I've got the data.
Is the time in seconds since Jan 1, 1970 or some other calculation?
Seconds since Jan 1st 1970 00:00 UTC.

Is there a utility with Xymon to convert it to date and time?
No, but if you only want to use it to check how long ago something
happened, then you don't need to convert it to human-readable form.
Just compare it against the value from "date +%s".

I have a simple C program that will do the conversion, I think it
is trivial to do in Perl as well (not a Perl person myself, though).

Here is the command I used:
/home/xymon/server/bin/bb 127.0.0.1 "hobbitdboard page=PW

You didn't specify "test=conn" in that command, so you're getting the 
result from the "conn" status as well as the "trends" and "info"
columns (you can see that if you add "testname" in the fields-list).


P.S.  Is there a location with all the fields you can request?
See the bb(1) man-page.

If you need to convert 'seconds since Jan 1, 1970' format to another format, and have GNU date command available, you can use '@seconds' with the '-d' flag:

Using SuSE Linux 10.1:
# date -d "jan 23 2008 14:32:05" +%s
1201116725

# date -d "@1201116725"             
Wed Jan 23 14:32:05 EST 2008


Using MacOS X:
date -r 1201116725
Wed Jan 23 14:32:05 EST 2008

BB = the path to your hobbit binaries + the bb binary itself. (i.e.
/hobbit/server/bin/bb).

BBDISP = the IP address or name (if you have dns running) of your
BBDISPLAY server.  If everything is on the same machine, you can use the
loopback address.

I tried the command but there was no output.  I tried it with and without
'lastchange'.

What are BB and BBDISP set to.
When I echo them they are empty.

$BB $BBDISP "hobbitdboard page=PW color=red,green
fields=hostname,color,lastchange"
-bash: hobbitdboard page=PW color=red,green
fields=hostname,color,lastchange: command not found

[root at monitor1 ~]# su - xymon
[xymon at monitor1 ~]$ echo $BB

[xymon at monitor1 ~]$ echo $BBDISP

[xymon at monitor1 ~]$

Thanks

I would like to have XYMON:
        E.G.  All printers are down at the same time - ALERT
              All printers just came back up at the same time -
NOTIFY/ALERT

I need to watch multiple printers in a building to see if they are ALL
down (or come up) at the same time.
This is the makings of a POWER OUTAGE EVENT for that building since the
printers are not attached to a UPS.
If all down, Possible Power Outage
Assuming you have some way of easily identifying your printers
- e.g. they are all on the same webpage in the Xymon display, or
they have some sort of standard name - then you can use the
'hobbitdboard' command to check the status of all of them at
once.

E.g. if you have all the printers on a page called "printers",
then this would tell you if they were all down:

   #!/bin/sh

   # Grab "conn" status of all systems on "printers" page
   # Only pick the red and green ones, so we ignore those that
   # have been disabled.
   $BB $BBDISP "hobbitdboard page=printers color=red,green test=conn
fields=hostname,color" >/tmp/printstatus.$$
   PRINTERCOUNT=`wc -l /tmp/printstatus.$$`
   DOWNCOUNT=`grep '^|red$' /tmp/printstatus.$$ | wc -l`

   if test $PRINTERCOUNT = $DOWNCOUNT
   then
      echo "All printers down!"
   fi

What I would do is feed the information from this script back into
Xymon as a new status - one that shows red if all printers are down,
and green if at least one of them is up. Then you can trigger the
alert from this status, instead of mucking about with the alert
scripts for each of the printers. So you could modify the script
above to become a Xymon server-side extension:

   #!/bin/sh

   # ... beginning is the same ...

   if test $PRINTERCOUNT = $DOWNCOUNT
   then
       # All printers are down
       $BB $BBDISP "status whitehouse.power red `date`
                    Possible power-loss at 1600 Pennsylvania Av"
   else
       # At least one printer is up
       $BB $BBDISP "status whitehouse.power green `date`
                   Power OK"
   fi


And then setup an alert that goes off when the "power" status for
host "whitehouse" goes red.

You'd run the script from hobbitlaunch.cfg every so often, e.g.
to run it every 5 minutes add
   [powercheck]
       CMD $BBHOME/ext/powercheck.sh
       INTERVAL 5m
to hobbitlaunch.cfg


If you must check if the change for each printer happened "recently"
(e.g. within the past 5 minutes which is the default network test
frequency), then you can add "lastchange" to the list of the fields
retrieved in the hobbitdboard command. That will give you the Unix
timestamp when the status last changed; you can then have the script
compare that to the current timestamp and do whatever appropriate if
the change happened more or less recently. (The GNU 'date' utility
can give you the current timestamp with "date +%s").
