This addon installs hardware monitoring tools and configures Nagios checks for the system hardware and storage monitoring.
Vendors supported: Dell (MegaRAID) Supermicro (LSI SAS) Huawei (LSI SAS) NVMe cards from Intel and Samsung (see README)
Tools supported: freeipmi tools (ie. ipmimonitoring, ipmi-sel, etc.) megacli mdadm nvme sas2ircu sas3ircu
The hw-health charm will no longer be maintained by nagios-charmers. If you have this charm installed without a publisher (i.e. "cs:hw-health") you do not need to do anything. The charm will automatically update to the new maintainer. If you are referencing "~nagios-charmers/hw-health" you will need to update to the new maintainer: "~llama-charmers/hw-health" (https://jaas.ai/u/llama-charmers/hw-health)
This charm installs various hardware system monitoring tools and configures Nagios NRPE checks. It will only work for bare-metal installations on specific hardware.
Currently supported hardware is:
- Dell: LSI Logic MegaRAID SAS-3 3108 Invader
- Supermicro: LSI SAS3008 RAID card with sas3ircu (Broadcoam's SAS3IRCU_P16)
- Huawei: LSI SAS2308 RAID card with sas2ircu (Huawei FusionServer Tools InfoCollect)
- SSD cards: Intel's PCIe Data Center SSD, Samsung's NVMe controllers for SM961/PM961 and 172Xa/172Xb.
- Linux software RAID (mdadm)
- IPMI as implemented by freeipmi (enable_ipmi config option is enabled by default)
In the backlog, hp-health logic still needs to be backported to support Hewlett-Packard equipment (HP Smart Array Controllers and MSA Controllers with hpacucli, hpssacli, ssacli).
Furthermore, other hardware in the roadmap is:
- Huawei's ES3000 V2 PCIe SSD Card with hio_info (Huawei ES3000 V2 Driver)
- S.M.A.R.T. Monitoring tool (smartctl)

The Charmstore version already ships a resource. However, this resource is empty to avoid violating software redistribution license issues. To be useful, a new resource must be attached that includes your hardware manufacturer's RAID tools:
- Option 1:
juju deploy hw-health --resource tools=/tmp/zipfile.zip
- Option 2:
juju attach-resource hw-health tools=/tmp/zipfile.zip
In both cases format of zipfile.zip must be one of the following:
zip /tmp/zipfile.zip megacli sas2ircu sas3ircu zip /tmp/zipfile.zip megacli etc.
Known Limitations and Issues
Charm only install method is via Juju resources. There are plans to support snaps but snapstore only supports strictly confined snaps. Hardware monitoring tools need special permissions that are under development.
"tools" resource needs to be attached in ZIP format, and hardware monitoring tool(s) need to be on the first level of the archive tree.
Building the tools.zip resource
In order to build the tools.zip resource it is necessary to source the binaries from the respective vendor support pages.
You will then have to extract, rename, and compress the binaries to obtain the following structure:
$ zipinfo tools.zip Archive: tools.zip Zip file size: 1204457 bytes, number of entries: 3 -rwxr-xr-x 3.0 unx 2720320 bx defN 19-Jan-16 11:31 megacli -rwxrwxr-x 3.0 unx 559164 bx defN 19-Jan-16 11:31 sas2ircu -rwxrwxr-x 3.0 unx 562560 bx defN 19-Jan-16 11:31 sas3ircu 3 files, 3842044 bytes uncompressed, 1204005 bytes compressed: 68.7%
Manufacturer option needs to be left in auto mode.

Upstream Project Name
- (boolean) Enable debug logging.
- (boolean) Enable the use of freeipmi tools to monitor hardware status.
- (string) Space separated list of extra deb packages to install.
- (string) List of signing keys for install_sources package sources, per charmhelpers standard format (a yaml list of strings encoded as a string). The keys should be the full ASCII armoured GPG public keys. While GPG key ids are also supported and looked up on a keyserver, operators should be aware that this mechanism is insecure. null can be used if a standard package signing key is used that will already be installed on the machine, and for PPA sources where the package signing key is securely retrieved from Launchpad.
- (string) List of extra apt sources, per charm-helpers standard format (a yaml list of strings encoded as a string). Each source may be either a line that can be added directly to sources.list(5), or in the form ppa:<user>/<ppa-name> for adding Personal Package Archives, or a distribution component to enable.
- (string) Additional options to be passed to check_ipmi_sensor. For non-standard ipmi implementations you might for example need "--seloptions '--assume-system-event-records'"
- (string) Choose the tools to get deployed (hp, dell, supermicro, huawei) or leave the charm to self discover the tools needed to run hardware health checks. The special value "test" is only useful during testing to bypass installation restrictions and override hardware detection. Only "auto" and "test" are currently implemented.
- (string) Used by the nrpe subordinate charms. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-myservice-0 If you're running multiple environments with the same services in them this allows you to differentiate between them.
- (string) A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup
- (string) The status of service-affecting packages will be set to this value in the dpkg database. Valid values are "install" and "hold".
- (string) DEPRECATED. Use snap-http-proxy and snap-https-proxy model configuration settings. HTTP/HTTPS web proxy for Snappy to use when accessing the snap store.
- (string) DEPRECATED. Use snap-store-proxy model configuration setting. The address of a Snap Store Proxy to use for snaps e.g. http://snap-proxy.example.com
- (string) How often snapd handles updates for installed snaps. The default (an empty string) is 4x per day. Set to "max" to check once per month based on the charm deployment date. You may also set a custom string as described in the 'refresh.timer' section here: https://forum.snapcraft.io/t/system-options/87
- (int) Amount of time allowed for scripts to run before exiting.
