Hello, I'm trying to create a dashboard panel to monitor node storage utilization percentage, but encountering data inconsistencies with the

system.filesystem.usage

metric. Problem Details: • Inconsistent Results: The calculated percentage values are wildly inconsistent and incorrect: ◦ Sometimes shows: 12.5% ◦ Other times shows: 671309764836%, 5361782579200%, 671314477511% • Configuration Attempts: ◦ Query A:

system.filesystem.usage

with filter

host.name = '$host.name' AND state = 'used'

◦ Query B:

system.filesystem.usage

(attempting to get total capacity) ◦ Formula:

(A / B) * 100

• Specific Errors Encountered: ◦ "key

host.name

not found" ◦ "key

state

not found" ◦ Results show "NaN%" when trying different filter combinations • Attempted Solutions: ◦ Tried various metric combinations (

system.filesystem.total

,

system.filesystem.size

) ◦ Attempted different filter attributes ◦ Tested with and without filters - all produce invalid results Expected Outcome: A reliable filesystem usage percentage (0-100%) for monitoring node storage utilization. Request: Please provide guidance on: 1. Correct metric names and attribute filters for filesystem usage calculation 2. Proper query structure for percentage calculation 3. Available attributes for the

system.filesystem.usage

metric Environment: SigNoz deployment monitoring Kubernetes/EKS infrastructure
