I will give an example of monitoring the number of running Samba processes, as well as creating a triggering trigger when there are no running processes.
In a system with Samba, a Zabbix agent must be installed.
See my popular articles about Zabbix.
Create a template, for example, with a name “Template Service Samba” and add the following data item to it:
Name: Number of processes nmbd Type: Zabbix agent Key: proc.num[nmbd]
Similarly, we create for smbd.
You can also create data items that represent the amount of memory used by the process, in which case the key will look like this:
proc.mem[nmbd,,sum]
And also add graphics for them.
Now add a trigger for each process to see when the process is not running:
Name: Does not work nmbd on {HOST.NAME}
Expression: {Template Service Samba:proc.num[nmbd].max(1)}<1
Done.
