i need to achive alerts from alertmanager for linux HDD  
with

Labels  
alertname = Host Out Of Diskspace  
instance = xx.xx.xx.xx:9100  
job = Webserver  
severity = warning

only , but i got mount points alerts also with amost 163 alerts firing for single server  
HDD alert , my alert rule is

**- alert: HostOutOfDiskSpace**  
**expr: (node\_filesystem\_avail\_bytes \* 100) / node\_filesystem\_size\_bytes \< 15 and ON (instance, device, mountpoint) node\_filesystem\_readonly == 0**  
**for: 5m**  
**labels:**  
**severity: warning**  
**annotations:**  
**summary: Host out of disk space (instance {{ $labels.instance }})**  
**description: "Disk is almost full (\< 15% left)\n VALUE = {{ $value }}\n LABELS = {{ $labels }}"**

what else to be done in rule to avoid mountpoint alerts  
attached the alert firing
