Log file monitoring and Not supported status in Zabbix 1.8.5

[MartinJanda]

Hi,
I have a problem using the log monitoring function. I followed the instructions in documentation.

Zabbix after adding a new item shows Not supported in status and ZBX_NOTSUPPORTED in error column.

Server and agent running on the same Linux server - Debian Lenny, 64b, Zabbix 1.8.5. The other items are ok. The file is set for read for all.

Any ideas? Thanks in advance.

Maybe:
Your item have to be a "Zabbix agent (active)" check, and you have to have this feature enabled on the agent (config file).

Thank you for your idea, but item is "Zabbix agent (active)" and active feature is not disabled in config file.

In the agent log is:
8504:20110816:164159.589 Starting Zabbix Agent. Zabbix 1.8.5 (revision 19050).
8505:20110816:164159.589 agent #0 started [collector]
8506:20110816:164159.589 agent #1 started[listener]
8507:20110816:164159.590 agent #2 started[listener]
8508:20110816:164159.590 agent #3 started[listener]
8509:20110816:164159.590 agent #4 started [active checks]
8509:20110817:125401.349 Cannot stat ['/mypath/myfile.log'] [No such file or directory]
8509:20110817:125401.349 Active check [log['/mypath/myfile.log','INFO','UTF8',100]] is not supported. Disabled.

Path is ok, i try login as zabbix user and try cat this file and it works.

[MartinJanda]

Thank you for our time.

I wrote, user zabbix has read rights to parse that file. (I try login as zabbix and I used 'cat' command for show this log file).

Any other ideas?

Same issue

Hi MartinJanda,

could you make it work ?

I use v1.9.7 server and agent.

Error I see is:
item [Zabbix server:log["/var/log/messages","ERROR","UTF-8",100]] became not supported: ZBX_NOTSUPPORTED

Thanks

Hi nkinchev,
I spent a lot of time and tried everything possible. It still does not work.

When i start agentd with DebugLevel=4, in agentd log I see:

I use zabbix 1.8.5. I'll wait for version 1.8.9 and I will do a upgrade. Perhaps the problem will be solved.

[MartinJanda]

Today I tried to watch zabbix agentd through strace, to see if agentd try to check the log file. In the output I didn't find operation on the file. On the server, however, item switch from active to not supported state. Strange.

I will try to delete the host and recreate. If it does not work, I wait for the release version 1.8.9 and try to upgrade the Zabbix.

If anyone has any idea, thank you.

[MartinJanda]

I tried to delete the host and I re-created. Same result: log function doesn't work.

Had the same problem, lost few hours on debugging this. The solution was so simple and silly...

8509:20110817:125401.349 Active check [log['/mypath/myfile.log','INFO','UTF8',100]] is not supported. Disabled

Quotes at item key must be "/mypath/myfile.log"

[MartinJanda]

Sour, you're right, thank you very much. Finally, I can watch log files.

Quotes at item key must be "/mypath/myfile.log", others must be '.
