Overview¶
The HPE Alletra Storage MP B10000 onboard exporter can be enabled by a storage administrator in the array UI. Learn how at the HPE Support Center.
Example Prometheus Scrape Configuration¶
The onboard exporter requires a username and password to be scraped. Credentials are sent over SSL using basic HTTP authentication. Below is an example scrape configuration for Prometheus.
...
- job_name: my-array-0
metrics_path: /metrics
scrape_interval: 30s
static_configs:
- targets: ['192.168.1.100:443']
basic_auth:
username: user
password: prometheus
scheme: https
tls_config:
insecure_skip_verify: true
...
Hint
The scrape_interval may not be lower than 30 seconds. See limitations.

Limitations¶
The onboard exporter up to 10.5 comes with these current known limitations.
- The onboard exporter runs on a throttled thread what only allows being scraped every 30 seconds. Any scrape attempt outside the allotted window will return an HTTP error.
- The onboard exporter does not provide any capacity metrics.
