What is the Prometheus alert rule for "OpenEBS used pool capacity"?

OpenEBS Pool use more than 80% of his capacity PromQL expression: openebs_used_pool_capacity_percent > 80. Severity: warning. Duration: 2m.

What is the Prometheus alert rule for "OpenEBS LVM volume group capacity high"?

OpenEBS LVM LocalPV volume group {{ $labels.instance }} is using more than 90% of its capacity ({{ $value }}%). Free up space or expand the volume group to avoid provisioning failures. PromQL expression: ((lvm_vg_total_size_bytes - lvm_vg_free_size_bytes) / lvm_vg_total_size_bytes) * 100 > 90. Severity: warning. Duration: 2m.
