HP iLO Check Reference

The HP iLO Check monitors HPE ProLiant servers via their iLO management interface using SNMP and captures temperature, fans, power supplies, hard drives, and memory.

Configuration fields

FieldTypeRequiredDefaultDescription
HostStringYes—iLO hostname or IP address
SNMP versionSelect (v2c / v3)Yesv2cSNMP protocol version used to query the device
SNMP CommunityStringNopublicSNMP v2c community string. Only shown when SNMP version is not v3.
SNMPv3 userStringNo—USM user name. Only shown when SNMP version is v3.
Authentication protocolSelect (None / SHA-1 / SHA-256)NoNoneMessage authentication algorithm. Only shown when SNMP version is v3.
Authentication passwordPasswordNo—Only shown when SNMP version is v3 and an authentication protocol is selected.
Privacy protocolSelect (None / AES-128 / AES-192 / AES-256)NoNonePayload encryption algorithm (requires authentication). Only shown when an authentication protocol is selected.
Privacy passwordPasswordNo—Only shown when a privacy protocol is selected.
Temperature Thresholds (Ambient)
Warning temperature (°C)NumberNo35Ambient temperature above this value triggers a warning
Critical temperature (°C)NumberNo42Ambient temperature above this value triggers a critical result

Collected metrics

  • Server model and serial number
  • Overall health status
  • Ambient and component temperatures
  • Fan speeds and status
  • Power supply status (OK, degraded, failed)
  • Physical hard drive status
  • Memory module status (Not Present, Not Supported, Ok, Degraded, Failed)

Platform support

PlatformSupported
WindowsYes (network-based)
LinuxYes (network-based)
macOSYes (network-based)

The check runs on the agent device and connects to the iLO interface via SNMP.

Notes

  • Requires an HPE ProLiant server with iLO (any version) and SNMP enabled on the iLO management processor.
  • The check uses standard Compaq/HPE Health (CPQHLTH, CPQIDA, CPQSINFO) MIB OIDs, which are present on iLO 2 and later.
  • Fan and power supply states map automatically (Degraded → warning, Failed → critical) — no configurable thresholds. Temperature thresholds are configurable, but only apply to sensors whose name begins with "Ambient" — they have no effect on CPU, System, or Memory temperature sensors.
