CPU trigger showing unkown

[ksteely]

I am very new to Zabbix and so far, I'm liking it!

I have a few questions though.

I did a stress test on one of my servers and received the notification via email. The subject line reads "cpu load too high on server xyz" which is correct. However, the body of the email shows:

Item values:

1. Processor load (1 min average per core) (xyz:system.cpu.load[percpu,avg1]): 13.3 2. *UNKNOWN* (*UNKNOWN*:*UNKNOWN*): *UNKNOWN* 3. *UNKNOWN* (*UNKNOWN*:*UNKNOWN*): *UNKNOWN*

What are all of these unknowns? I don't even see what the CPU load is anywhere.

My trigger message is:

Trigger: {TRIGGER.NAME}
Trigger status: {TRIGGER.STATUS}
Trigger severity: {TRIGGER.SEVERITY}
Trigger URL: {TRIGGER.URL}

Item values:

1. {ITEM.NAME1} ({HOST.NAME1}:{ITEM.KEY1}): {ITEM.VALUE1}
2. {ITEM.NAME2} ({HOST.NAME2}:{ITEM.KEY2}): {ITEM.VALUE2}
3. {ITEM.NAME3} ({HOST.NAME3}:{ITEM.KEY3}): {ITEM.VALUE3}

Original event ID: {EVENT.ID}

2nd/3rd) I have an action to notify on discovered hosts - not working (even though they are discovered). Also, one of the default linux triggers is /etc/passwd change and I don't receive alerts on that. This isn't a big deal, I'm just trying to understand the alert system better.

For the user that is receiving alerts, I have all severities checked.

Your help is appreciated.

What did you set the expression for trigger?

"Item values" will display the value of each item to be included within the expression.
If the item to the expression contain only one, it does not appear 2nd and 3rd.
