Issues not staying in Last 20 Issues list

[bkowalewski]

I have several active issues on several of my monitored servers, but the Last 20 Issues list only shows the latest one. When I hover over the issue count in the System Status display for the other issues, it says "No Data" in the Actions column. There aren't a flood of other issues coming and going from the list.

I am running 1.8.3 on a Solaris 10 server, mysql for a DB... small installation - 84 hosts monitored, 7.88 values/sec.

Any ideas?

If you're getting "no data" then you're either not receiving data from the hosts/agents or you're not writing it to database fast enough (check Administration -> Queue then look at details in the drop-down).

Try these steps to troubleshoot farther.

It's not a question of the "no data" being received. It's a question of why are the issues disappearing from the "Last 20" list. Zabbix is relatively underutilized on that monitoring server (previously, I had been monitoring around 2000 hosts on that box), and is not even breathing hard.

When they drop off the "Last 20" list, the Actions column changes to "no data" in the system status grid node. Before that, it would say "OK".

Something seems to be timing out in the display or being cleared or corrupted in the DB, but what?

Did you update to 1.8.4? I've watched my own triggers/events appear, get acknowledged, seemingly disappear, and then pop back up in the last20 display again, but complete with Acks, etc.

I wonder if that's similar to what you're seeing.

On 1.8.3. Upgraded a while ago from 1.6.6 .
