Display item "TOTAL DISK SPACE" into mail alert action

[AVB]

Hello,

I'am using zabbix 4.0.4. Actually I monitor my % disk space free with the mounted filesystem discovery (available in the Windows OS Template ).

I want to add (as information ) to my mail alert the ITEM " vfs.fs.size[{#FSNAME},total]" because a host can have 5% free disk space but the TOTAL disk space can have a huge space available. How can i do it in zabbix?

Thank you,


This is my actual trigger :
Total disk space < 5% on volume {#FSNAME}
{Template OS Windows:vfs.fs.size[{#FSNAME},pfree].last(0)}<5

And this is my action rule ( send email to administrator) :

{TRIGGER.HOSTGROUP.NAME} / Problem: {EVENT.NAME}
Problem {EVENT.TIME} {EVENT.DATE}

Nature : {EVENT.NAME}
Host: {HOST.NAME} - {IPADDRESS}
Criticality: {EVENT.SEVERITY}
