Unsupported item : Cannot evaluate expression

[manjunathan]

Hi,

I am facing issues with my triggers. which is working earlier but now the items are not supported
current Zabbix version is Zabbix 4.2.4

Error:
Cannot evaluate expression: "Cannot evaluate function "Host:log[/serverlogs/test/server.log, encryptdata/rest/EncryptapplicationData/EncryptDetail: Connection refused,1].last()": item is not supported.".

Thank you

I think that the item log[] has not been acquired. Please check the log to see why the log cannot be retrieved. For example, the user running Zabbix agent may not have permission to access that log files.

Dear Atsushi,

Thank you so much for the reply.

I can able to ping the log server from zabbix . Also i can able to monitor the other log file from same server.
Eg: item key: log[/home/rest/response/mmmmmm.log] -- this item and trigger is working fine


Need to monitor the below mentioned logfile based on error keywords from same server but logfile path is different

item Key: log[/home/ac_log/application/mmmmmm.log,java.lang.NoClassDefFoundError: Could not initialize class xxxxx.yyyyy.jni.JSGFPLib,1]
Type of information: log
Trigger: log[/home/ac_log/application/mmmmmm.log,java.lang.NoClassDefFoundError: Could not initialize class xxxxx.yyyyy.jni.JSGFPLib,1].logsource()}=1

(is there any issue with error log keywords)

Thank you
