Blank graphs

[Neo]

I dont know what happened to all the graphs on my Zabbix 1.0 server, they are all blank now (all the hosts are in monitored state)
Here is a snapshot of the graph (monthly).
I can seem to figure out what is wrong?
Any help will be greatly appreciated.

I just tried clicking on the "Status of Zabbix" Link, but it looks like the page is not coming up at all.

Is Zabbix able to see all of the hosts it is monitoring? I mentioned this in another unrelated post to you, but I've had some problems with Zabbix's queue filling up with items from a host that is down, but still monitored. Check your queue and see how many items you have there, and which items are the first in line. Those tend to be the cause of your data collection problems.

There are 160 items in the queue right now. The top one is a check for FTP server running on one of the servers the next few ones are processor load checks......
Ok i checked it again and the queue had a different set now. So i think its working fine.

Same things as mentioned above is happening with me. Not sure of what a fix it -- would be nice if someone has figured out something in the short run... way to clear the queue?


I've restarted zabbix_server, didn't do any good.

Thanks :-p

I think what you're running into is an item (or items) that are checking an unavilable resource, and are holding up the queue waiting for that item. I'm not sure why Zabbix tends to get snagged on these items, but I think I know why restarting Zabbix doesn't help. It looks like the queue is calculated by looking at all your items in the Zabbix database, and sorting them by their nextcheck value. So even if you restart the Zabbix server, the nextcheck values will stay the same, and the queue won't change.

I would suggest that if you have some items clogging up your queue, you might try turning them off to see if that gets thinks moving again. It looks like the queue checks to see if the item's status is 0 (active) before including it in the queue, so turning the items off may let the queue skip over them. If not, you might have to edit your database manually to set the nextcheck value to a different value.

I don't know of a better solution yet, but would love to learn one.

So, where does one find this queue that is filling up? I have the same issue
