"""Create snmp_metrics hypertable for custom SNMP metric storage.

Revision ID: 040

Revises: 039
|
|
Create Date: 2026-03-21
|
|
|
|
Stores OID data that does not map to the standard interface_metrics or
|
|
health_metrics hypertables (e.g., UPS battery voltage, vendor-specific
|
|
counters, custom profile OIDs). Structured as a flexible key-value
|
|
time-series: metric_name + metric_group identify the series, value_numeric
|
|
and value_text hold typed values, index_value tracks SNMP table row index.
|
|
|
|
90-day retention matches existing hypertable policy. RLS enforces
|
|
tenant isolation.
