• collect-timeout | int

  Default: 10

  Timeout for collectors' shell commands in seconds. Changing this will also change the scrape_timeout config option for prometheus for the cos-agent relation with grafana-agent. This value is also used for the redfish client's timeout parameter. The value of this timeout should not be greater than prometheus scrape_interval (which is 60 seconds by default), as it greater would cause the scrape_timeout to be greater than scrape_interval.

• dcgm-snap-channel | string

  Default: auto

  Valid inputs are auto, v3/stable, v3/candidate, v3/edge, v4/stable, v4/candidate, v4/edge.

  When set to auto, the charm automatically checks the installed NVIDIA driver version and selects the most appropriate channel. For example, with driver 580, it will install from v4-cuda13/stable. The charm won't block if the driver is not installed or loaded.

  The v3 channels are compatible with CUDA 10, 11, and 12; you simply choose the desired release risk (stable, candidate, or edge).

  The v4 channels provide more flexibility. Even if you select v4/edge, the charm still detects the driver version and installs the matching CUDA build. For example, with driver 570, it will install from v4-cuda12/edge.

• exporter-log-level | string

  Default: INFO

  Start the prometheus exporter with log level "exporter-log-level". By default, it will set to INFO. Allowed values are "DEBUG", "INFO", "WARNING", "ERROR", "CRITICAL". Values other than those will result in failure of the exporter.

• hardware-exporter-port | int

  Default: 10200

  Start the prometheus hardware exporter at "hardware-exporter-port". By default, it will start at port 10200.

• ipmi-driver-type | string

  Specify the driver type to be used for IPMI. Use LAN_2_0 for IPMI over LAN.

• redfish-disable | boolean

  Default: True

  By default the Redfish collector is disabled. Set this option to false to enable it.

• redfish-password | string

  This password is used to log in to the Redfish server and the BMC when IPMI over LAN is enabled.

• redfish-username | string

  This username is used to log in to the Redfish server and the BMC when IPMI over LAN is enabled.

• smartctl-exporter-port | int

  Default: 10201

  Start the prometheus smartctl exporter at "smartctl-exporter-port". By default, it will start at port 10201.

• smartctl-exporter-snap-channel | string

  Default: latest/stable

  Channel to install the Smartctl exporter snap if the hardware has smart disk. By default, it will install from latest/stable.
