I can't seem to get a simple command to work

[edlentz]

have a version 6.4.7 server running and an Agent2 version 6.4.2 on a Centos machine. I can assign a generic linux template and I can get info just fine. What I am trying to do is have a minimalist template. Just monitoring a few services and the disk space used. For instance I have this key service.info[mariadb,status] to get the status of the DB. I get an error: cannot monitor metric "service.info[mariadb,status]": Unknown metric service.info from the agent log. When I try a zabbix_get command (zabbix_get -s xxx.xxx.xxx.xxx -p 10050 -k "service.info[mariadb,state]" I get : ZBX_NOTSUPPORTED: Unknown metric service.info If I run this from the cli on the host zabbix_agent2 -t "service.info[mariadb.service,state]" I also get the same error I got in the log file.

Can someone help me out in getting this to work?
Thanks

This is because the "service.info" key does not exist natively on Agent 6.4 for Linux systems.
The "service.info" key is a Windows specific key.

For Linux, I guess you must be looking to use the "systemd.unit.info" key.

Thanks markfree for the reply. I could not get the systemd.unit.info to work but I did get some items using system.run[systemctl is-active httpd.service] to work to monitor the http service on a Centos system. I get active and inactive responses at the correct times. My issue now is getting a trigger to work. So I use this as the expression {MinimalTest:system.run[systemctl is-active httpd.service].str(inactive)}=1 where my template name is MinimalTest and I get this as an error Invalid parameter "/1/expression": incorrect expression starting from "{MinimalTest:system.run[systemctl is-active httpd.service].str("inactive")}=1" I have checked and rechecked my spelling, punctuation, the result as text from the item. This shouldn't be this hard should it?

You appear to be using the old expression syntax.
Check the documentation for the current syntax.

function(/host/key,parameter)
