I am running Linhes 8.1 and in the past several weeks (months?) I have noticed Xymon's OSD occasionally warn that there is a red condition on Orphans. I will go to the health & maintenance page and find that it logged a zero byte recording which lasted for 5 minutes. I will then run find_orphans.py and it will return nothing. I think the OSD message tends to happen sometimes after a channel change or one program ends and another begins, but I do not notice any performance issues when watching. I am using a HDHomerun Prime over a Gigabit switch and I can't think of the last time anything changed in hardware or software on my machine unless something has updated unintentionally. I am just wondering if there is a way to suppress the OSD message or at least make it wait longer to popup which might reduce the false positives. I have looked through the Xymon configuration files a bit and found some settings for some of the other conditions but nothing on Orphans yet. It's just a minor inconvenience as I think it happens several times a day if watching live tv all day, but the message doesn't last long and it does not noticeably affect performance otherwise.

Hi

I have a HdHomerun OTA and it has been working fine for since I upgraded to R8 R8.1. The system looks fine. I notice once and a while a little trouble with ABC but that is more of a weak signal issue. I also have HDHomerun prime that is not currently hooked up.

Rather than supress the message I would recommend to try to isolate the problem. Generally speaking a weak signal will create a zero byte file. Since your network is good I would look at the cable line how many times is it split? How does the coax cable look to the prime?

Hi RacerX. The bizarre thing is that from the frontend I don't notice anything. It's not like it kicks me back to the menu or gives any error messages. Live TV keeps playing. I only have one two-way splitter between the cable modem and the HDHomerun prime. Unlike the original HDHomerun, I do not have to split it going into the prime. There just happened to be a cable outage in my area yesterday so once it was back up I checked the cable modem levels and they all looked extremely good as best I can tell.

Right now I am looking at the HDHomeRun Config on ABC HD and it is reading:
Signal Strength: 92%
Signal Quality: 100%
Symbol Quality: 100%

Aside from yesterday's outage, the history on xymon recently has been red on orphans:
Fri Jul 04 15:01:50 2014 for 5 minutes and 1 second
Fri Jul 04 11:01:16 2014 for 5 minutes and 0 seconds
Fri Jul 04 06:30:30 2014 for 5 minutes and 1 second
Thu Jul 03 17:36:53 2014 for 10 minutes and 3 seconds
Thu Jul 03 17:16:51 2014 for 5 minutes and 0 seconds
Thu Jul 03 16:41:45 2014 for 5 minutes and 2 seconds
Thu Jul 03 12:31:13 2014 for 5 minutes and 0 seconds
Thu Jul 03 11:46:06 2014 for 5 minutes and 1 second
Wed Jul 02 21:37:28 2014 for 5 minutes and 0 seconds

and it pretty much goes on like that. Are there any other logs that would provide any help? Is it maybe having trouble tuning and so it switches to a different tuner behind the scenes so that it's imperceptible? There probably is a perfectly good explanation, but I might need some help finding it.

Are you aware that you can use this script to clean up the orphans from the database?

Code:
find_orphans.py

knappster, I have a similar setup and I see the same thing you do. If I look at my xymon history there are "red" orphan events for a long time. I never could find out why but whatever causes it seems to rectify within hours (find_orphans.py usually finds nothing).

At first I ignored it but when I enabled email notifications, it became annoying so I disabled orphan monitoring. Problem masked...

Do you remember how you went about disabling only orphan monitoring? I think I may want to do the same for the time being...

I'm seeing the same 0 byte orphans, but they auto expire quickly so I ignore the messages. Figured I should test a little more incase it gets annoying.

If you access LinHES using a web browser and click the "Health & Maintenance" menu, then at the top of the screen click the "Administration", then click the "enable/disable" menu, you should be presented with a screen that allows you to pick your host and then the test you want to disable.

Testing on my system, I select my MBE and the Orphan test, enter something in Cause (this is a note section, so I entered Test), checked the Duration check box "Until OK" , made sure that disable now was checked and clicked apply. This disabled the orphans test, checking on the "Health & Maintenance" menu, the orphans indicator started flashing blue.

Regards.
Bruce.

Sorry for the lateness - been traveling. There are two things that I do - first is an entry in alerts.cfg (mine is HOST=* SERVICE=* EXSERVICE=conn,myth_mtc,func... You can exclude several here). The other is in the hosts.cfg. Check out the man page or the help drop down on the main xymon screen.
