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:

  • Any controller supported by the megaraid_sas driver (ie, any controller handled by the MegaRAID CLI)
  • 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.

Hardware-independent tools:

  • Linux software RAID (mdadm)
  • IPMI as implemented by freeipmi (enable_ipmi config option is enabled by default)
  • ipmiseld from the freeipmi suite (enable_ipmiseld is enabled by default) for logging system event log entries to syslog

In the backlog, hp-health logic still needs to be backported to support Hewlett-Packard gen8 and older equipment (HP Controllers with hpacucli)

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

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.

See https://forum.snapcraft.io/t/request-for-classic-confinement-sas2ircu/9023

"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.

For example: megacli/ sas3ircu/ sas2ircu

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%

Two more zip resources may be needed for functional tests to succeed:

  • tools-checksum.zip replaces the megacli tool by an empty file.
  • tools-missing.zip removes the megacli tool from the resource
$ zipinfo tools-checksum.zip
Archive:  tools-checksum.zip
Zip file size: 547860 bytes, number of entries: 3
-rwxr-xr-x  3.0 unx        0 bx stor 19-Jan-16 11:35 megacli
-rwxr-xr-x  3.0 unx   559164 bx defN 19-Jan-16 11:31 sas2ircu
-rwxr-xr-x  3.0 unx   660560 bx defN 19-Jan-16 11:31 sas3ircu
3 files, 1219724 bytes uncompressed, 547408 bytes compressed:  55.1%

$ zipinfo tools-missing.zip
Archive:  tools-missing.zip
Zip file size: 547718 bytes, number of entries: 2
-rwxr-xr-x  3.0 unx   559164 bx defN 19-Jan-16 11:31 sas2ircu
-rwxr-xr-x  3.0 unx   660560 bx defN 19-Jan-16 11:31 sas3ircu
2 files, 1219724 bytes uncompressed, 547408 bytes compressed:  55.1%

Note: vendor tools may be updated over time. The charm verifies that the shared binaries match a set of known checksums. If you feel a checksum is missing, please file a bug (see link below) and it will be added.


Manufacturer option needs to be left in auto mode.
