An HPE Storage Array Exporter for Prometheus deployment provides Prometheus metrics for a single storage system. A deployment can use an executable file or a container image.

Configuration¶

The address and credentials of the target storage system must be specified in a configuration file, using the format shown in this example storage-system.yaml file.

address: 10.10.10.1
username: exampleuser
password: examplepassword

The address value is either a resolvable hostname or IP address of the management interface on the storage system. The username value identifies a storage system user with privileges described below.

Storage System	User Type	Minimal Role	Open Ports Requirements
HPE Alletra Storage MP Block, Alletra 9000, Primera, 3PAR	System User	Browse	22, 443
HPE Alletra 5000/6000, Nimble Storage	System User	Guest	5392
HPE Alletra 5000/6000, Nimble Storage1	Tenant	N/A	443, 5392

¹ = NimbleOS 6.0 and above only.

Command Options¶

Option	Default	Description
--accept-eula	false	Confirms your acceptance of the HPE license restrictions
--log.path	None	A file location to write log messages, in addition to stdout
--metrics.disable-introspection	false	Excludes metrics about the metrics provider itself, with prefixes such as promhttp, process, and go
--telemetry.addr	:8080	The host:port address at which to provide metrics
--telemetry.path	/metrics	The endpoint path at which to provide metrics

Using an Executable File¶

A Linux executable file is provided through GitHub releases.

When an executable file has been copied to your server, it can be invoked with this command syntax:

hpe-array-exporter [OPTION]... CONFIG-PATH

Available OPTIONs are described in the Command Options section.

CONFIG-PATH is the location of the storage system configuration file.

Command Example¶

./hpe-array-exporter --log.path=/var/log/hpe-array-exporter.log /etc/config/storage-system.yaml

Using a Container Image¶

A container image is hosted at quay.io/hpestorage/array-exporter:v1.0.3, with v1.0.3 replaced by the desired release version.

When deploying the array exporter as a container, the configuration file must be mounted as a volume.

Available options, including the --log.path used in the example below, are described in the Command Options section.

Docker Example¶

In this example, the configuration file at /tmp/storage-system.yaml is bound to the container's /etc/config/ directory as a volume using Docker's -v command option. The configuration file location inside the container is then given as a command argument. In addition, the -p option is used to map the container's port 8080 to port 9090 on the Docker host.

docker run -it --name hpe-array-exporter -p 9090:8080 \
     -v /tmp/storage-system.yaml:/etc/config/storage-system.yaml \
     quay.io/hpestorage/array-exporter:v1.0.3 \
     --log.path /var/log/hpe-array-exporter.log \
     /etc/config/storage-system.yaml

Consult the Docker command line documentation for more information on running containers using Docker.

Using a Kubernetes Deployment¶

Kubernetes deployment facilities are hosted in the co-deployments repository, including a Helm chart (via Artifact Hub) and sample YAML files.
