Add HPE Nimble Storage using HTTP/SNMP discovery templates

[lucthienphong1120]

This template monitors HPE Nimble Storage (Nimble OS 5.x) all-flash arrays via SNMP v2c/v3 and HTTP RestAPI over HTTPS.

It uses the vendor's enterprise MIB (NIMBLE-MIB, enterprise OID .1.3.6.1.4.1.37447) for array-level performance and capacity metrics, IF-MIB for network interface monitoring, and SNMP Traps for hardware health alerting.

A single SCRIPT master item handles authentication, queries all API endpoints, and returns a consolidated JSON payload. All metrics are extracted using DEPENDENT items and Low-Level Discovery (LLD), minimizing API calls and load on the storage array.

Tested On

Product	Firmware
HPE Nimble Storage CS-Series	Nimble OS 5.0.10.0
HPE Alletra 6000	Nimble OS 6.x compatible

API Authentication Flow

1. POST /v1/tokens          → Get session token
2. GET  /v1/arrays/<id>     → Array details
3. GET  /v1/controllers/<id>→ Controller details (per ID)
4. GET  /v1/pools/<id>      → Pool details
5. GET  /v1/volumes/<id>    → Volume details
6. GET  /v1/disks/<id>      → Disk details
7. GET  /v1/network_interfaces/<id> → NIC details
8. GET  /v1/shelves/<id>    → Shelf details
9. GET  /v1/alarms/<id>     → Active alarm details
10. DELETE /v1/tokens/<token> → Logout

Macros

Macro	Default	Description
{$SNMP_COMMUNITY}	public	SNMP community string

SNMP Traps

Item	Key	Purpose
SNMP Trap: Hardware Alert	nimble.trap.hardware	Fan, PSU, disk, temperature events
SNMP Trap: All Events	nimble.trap.all	Catch-all for any array alerts

Discovery Rules

Volume Discovery

Automatically discovers all volumes via volName OID table (.1.3.6.1.4.1.37447.1.2.1.3).

Item prototypes per volume:

Prototype	Description
Volume {#VOL_NAME}: Size	Provisioned size in bytes
Volume {#VOL_NAME}: Used	Currently used bytes
Volume {#VOL_NAME}: Status	Online (1) / Offline (2)
Volume {#VOL_NAME}: Read IOPS	Per-volume read IOPS
Volume {#VOL_NAME}: Write IOPS	Per-volume write IOPS

Trigger prototypes:

• Volume {#VOL_NAME}: is Offline — HIGH
• Volume {#VOL_NAME}: Usage over 80% — WARNING

Network Interface Discovery

Discovers all network interfaces via IF-MIB::ifDescr (.1.3.6.1.2.1.2.2.1.2). Loopback (lo) is excluded automatically.

Item prototypes per interface:

Prototype	Description
Interface {#IF_NAME}: Status	Operational status (up/down)
Interface {#IF_NAME}: In	Inbound traffic (bps)
Interface {#IF_NAME}: Out	Outbound traffic (bps)

Trigger prototypes:

• Interface {#IF_NAME}: Down — AVERAGE

Triggers

Trigger	Severity	Description
Nimble: No SNMP data collection	WARNING	SNMP polling not reachable
Nimble: Device has been restarted	WARNING	Uptime < 10 minutes
Nimble: System name has changed	INFO	Hostname change detected
Nimble: Hardware alert received via SNMP Trap	HIGH	Any hardware trap received

Value Maps

Name	Values
Nimble Volume Status	1=Online, 2=Offline
IF-MIB::ifOperStatus	1=up, 2=down
zabbix.host.available	0=not available, 1=available, 2=unknown
