NAME

       check_hp_bladechassis - Nagios plugin for checking the status of HP blade enclosures via
       SNMP

SYNOPSIS

       check_hp_bladechassis -H <HOSTNAME> [OPTION]...

DESCRIPTION

       check_hp_bladechassis is a plugin for the Nagios monitoring software that checks the
       hardware health status of a HP blade enclosure/chassis. The plugin is only tested with the
       c7000 enclosure.

COMMON OPTIONS

       -H, --hostname HOSTNAME
           The transport address (hostname or IP) of the blade enclosure you want to monitor.
           This option is mandatory.

       -C, --community COMMUNITY
           This option expects a string that is to be used as the SNMP community name when using
           SNMP version 1 or 2c.  By default the community name is set to "public" if the option
           is not present.

       -p, --perfdata
           Collect performance data. Performance data collected is total power usage.

       -t, --timeout SECONDS
           The number of seconds after which the plugin will abort. Default timeout is 30 seconds
           if the option is not present.

       -i, --info
           Prefix any alerts with the enclosure serial number.

       -v, --verbose
           In case of an alert, the part number, spare part number and serial number of the
           failed component is appended to the alert message.

       -e, --extinfo
           Display a short summary of system information (product, serial number, firmware and
           the number of blades and I/O modules) in case of an alert.

       -s, --state
           Prefix each alert with its corresponding service state (i.e. warning, critical etc.).
           This is useful in case of several alerts from the same monitored system.

       --short-state
           Same as the --state option above, except that the state is abbreviated to a single
           letter (W=warning, C=critical etc.).

       -d, --debug
           Debug output. Will report status on all monitored subsystems, regardless of their
           alert state. Will also report total power usage.

       -h, --help
           Display help text.

       -V, --version
           Display version info.

ADVANCED OPTIONS

       -P, --protocol PROTOCOL
           SNMP protocol version. This option is optional and expects a digit (i.e.  1, 2 or 3)
           to define the SNMP version. The default is 2, i.e. SNMP version 2c.

       --port PORT
           SNMP port of the remote (monitored) system. Defaults to the well-known SNMP port 161.

       -U, --username SECURITYNAME
           [SNMPv3] The User-based Security Model (USM) used by SNMPv3 requires that a
           securityName be specified. This option is required when using SNMP version 3, and
           expects a string 1 to 32 octets in lenght.

       --authpassword PASSWORD, --authkey KEY
           [SNMPv3] By default a securityLevel of "noAuthNoPriv" is assumed.  If the
           --authpassword option is specified, the securityLevel becomes "authNoPriv".  The
           --authpassword option expects a string which is at least 1 octet in length as
           argument.

           Optionally, instead of the --authpassword option, the --authkey option can be used so
           that a plain text password does not have to be specified in a script.  The --authkey
           option expects a hexadecimal string produced by localizing the password with the
           authoritativeEngineID for the specific destination device.  The "snmpkey" utility
           included with the Net::SNMP distribution can be used to create the hexadecimal string
           (see snmpkey).

       --authprotocol ALGORITHM
           [SNMPv3] Two different hash algorithms are defined by SNMPv3 which can be used by the
           Security Model for authentication. These algorithms are HMAC-MD5-96 "MD5" (RFC 1321)
           and HMAC-SHA-96 "SHA-1" (NIST FIPS PUB 180-1). The default algorithm used by the
           plugin is HMAC-MD5-96.  This behavior can be changed by using this option. The option
           expects either the string "md5" or "sha" to be passed as argument to modify the hash
           algorithm.

       --privpassword PASSWORD, --privkey KEY
           [SNMPv3] By specifying the options --privkey or --privpassword, the securityLevel
           associated with the object becomes "authPriv". According to SNMPv3, privacy requires
           the use of authentication. Therefore, if either of these two options are present and
           the --authkey or --authpassword arguments are missing, the creation of the object
           fails.  The --privkey and --privpassword options expect the same input as the
           --authkey and --authpassword options respectively.

       --privprotocol ALGORITHM
           [SNMPv3] The User-based Security Model described in RFC 3414 defines a single
           encryption protocol to be used for privacy.  This protocol, CBC-DES "DES" (NIST FIPS
           PUB 46-1), is used by default or if the string "des" is passed to the --privprotocol
           option. The Net::SNMP module also supports RFC 3826 which describes the use of
           CFB128-AES-128 "AES" (NIST FIPS PUB 197) in the USM.  The AES encryption protocol can
           be selected by passing "aes" or "aes128" to the --privprotocol option.

           One of the following arguments are required: des, aes, aes128, 3des, 3desde

       --linebreak=STRING
           check_hp_bladechassis will sometimes report more than one line, e.g. if there are
           several alerts. If the script has a TTY, it will use regular linebreaks. If not (which
           is the case with NRPE) it will use HTML linebreaks. Sometimes it can be useful to
           control what the plugin uses as a line separator, and this option provides that
           control.

           The argument is the exact string to be used as the line separator. There are two
           exceptions, i.e. two keywords that translates to the following:

           REG Regular linebreaks, i.e. "\n".

           HTML
               HTML linebreaks, i.e. "<br/>".

           This is a rather special option that is normally not needed. The default behaviour
           should be sufficient for most users.

DIAGNOSTICS

       The option "--debug" (or "-d") can be specified to display status of all components.

DEPENDENCIES

       The perl module Net::SNMP is required on the Nagios host.

EXIT STATUS

       If no errors are discovered, a value of 0 (OK) is returned. An exit value of 1 (WARNING)
       signifies one or more non-critical errors, while 2 (CRITICAL) signifies one or more
       critical errors.

       The exit value 3 (UNKNOWN) is reserved for errors within the script, or errors getting
       values via SNMP.
