Display Time when the Zabbix agent was last rebooted

[k122028]

Hi, I am using Zabbix LTS version and Ubuntu 18.04. my Agency is also using Ubuntu 18.04.
I need to display time when the agent was last rebooted. I can not seem to define triggers which give a warning when the agent was rebooted.
I hope I can get an easy solution here, Thanks in advance!

You can check the documentation for a native way to do this, but you can achieve it with:
ps -eo pid,lstart,cmd | grep zabbix-agentd
