description:
 PCIe Advanced Error Reporting counters of every PCIe device that supports AER:
 fatal errors since boot are CRIT, non-fatal (uncorrectable) ones WARN, new
 correctable errors WARN for one day. A growing count points to a flaky NVMe drive,
 card, riser or slot. Rule: "Linux hardware: PCIe errors".

discovery:
 One service on hosts with AER-capable PCIe devices.
