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 sametime - 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.

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.

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).
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 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
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.
Regards, Henrik
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 Tom

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 -lif 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
datePossible power-loss at 1600 Pennsylvania Av" else # At least one printer is up $BB $BBDISP "status whitehouse.power greendatePower OK" fiAnd 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

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 BBDISP is the IP of your Xymon server
