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.
