UserParameter - get temperature and monitore it

[Alex.polter]

Hi everyone!

So , i'm trying to get some results using UserParameter;

In this case I have edited agentd.conf (client) and adding this command

####temp template####
UserParameter=custom.temp.dev.read,cat /sys/class/thermal/thermal_zone0/temp | awk '{print substr ($1,1,2);}'
###################
Where the result of cat /sys/class/thermal/thermal_zone0/temp | awk '{print substr ($1,1,2);}' is printing first two digits of current temperature.

So how can I proceed to implement this command? I need to create Key itens ( I don't know to archive it) or just use " Show Value = As is" will be sufficient?

Only with the UserParameter, creating the trigger will it work?

I'm pretty sure it will not work because I don't know how to create te variable for example :custom.temp.dev.read[???] when creating the item.

Can you guys help me ?

Thanks Hamardaban!

Last day I just archived it with this solution:

create the entry on Agentd.conf as:


TEMPLATE
Create the temperature template

AGENT
#####temperature parameter#####
#1- Uncomment AllowRoot= 0 and anable it
UserParameter=temperatura,head -c 2 /sys/class/thermal/thermal_zone0/temp
#remember to refresh your agent with systemctl restart zabbix-agent
############################
Open your templeate then

ITEM
Create the Item on the template
Name it with someting like Temperature
Type zabbix agent
Key temperatura (same of your UserParameter)
Type of information Numeric (Unsigned)
Interval 3s (select your metric)
Units c (xen server displays it in ceusius)

GRAPH
Create one graph line using Y fixed to 100
In ITEM add the item template and select the graph type and color


Observations:

***head -c 2 will display only the first two digits of you first line because the temp value is given in 000000 and we need only the two first digits
***/sys/class/thermal/thermal_zone0/temp receive the system temperature in Ceusius (xen - redhat)


Sorry for my bad english,
