Description
Steps to reproduce:
- Create Template for Linux disk space
- Create Discover Rule (mounted file system)
preprocessing Json path - $[?(@.fsname=='/')].bytes.pfree.first()
LLD Macro ({#FSNAME} - $.fsname) ( {#FSTYPE} - $.fstype)
Filters ({#FSTYPE} matches @File systems for discovery
- Create Item prototype (Free Disk Space on {#FSNAME} (%))
key: vfs.fs.size[ {#FSNAME},pfree|#FSNAME},pfree]
no Preprocessing
# Create a trigger prototype ( Low Disk Space less than 5%)
# Add template to the host
Result:
Error
Preprocessing failed for: [{"
{#FSNAME}":"/sys","{#FSTYPE}":"sysfs"},{"
{#FSNAME}
":"/proc","{#FSTYPE}":"proc"},{"
{#FSNAME}
":"...
1. Failed: cannot extract value from json by path "$[?(@.fsname=='/')].bytes.pfree.first()": no data matches the specified path
