Another unsupported log item problem

[tvtue]

Dear zabbix users,

I have a problem with a log item which keeps beeing displayed as unsupported (ZBX_UNSUPPORTED) in the frontend.

I have a other monitored systems where this item works, so it 's not likely to be a setup problem on the server side. However it is a zabbix agent active check.

On the client the log file is readable for zabbix user. The permissions are added through posix ACLs.

I increased the log level and am seeing the following related lines:

18550:20160303:080229.330 In process_logrt() is_logrt:0 filename:'/var/log/messages' lastlogsize:164331 mtime:0 error_

 18550:20160303:080229.330 End of process_logrt():SUCCEED error_count:0

I am unsure but shouldn't that be enough to say the log item is ok?

In Administration -> General -> Other the refresh interval of unsupported item is set to 600 seconds.

Server and agent are version 2.4.7


Where else can I check why it is still unsupported?

TIA
Timo

I've had the same issue twice so far, once in 2.4 and once in 3.0. The solution in each case was to change the item to passive, wait until it becomes supported and then change it back to active.

Hello mbrackeva,

thank you for your reply.

I thought log items must be of agent active kind, don't they?

Also I cannot change this item on a host basis. it is used in a template for a lot of hosts where not all of them are broken.

regards,
timo
