monitor

开发snmp的开发包有两个开放的SNMP开发库

title Monitor Various Aspects of the Running Host
description The following check up on various aspects of a host.

token proc
info Check for processes that should be running.
info #  proc NAME [MAX=0] [MIN=0]
info #
info #  NAME:  the name of the process to check for.  It must match
info #         exactly (ie, http will not find httpd processes).
info #  MAX:   the maximum number allowed to be running.  Defaults to 0.
info #  MIN:   the minimum number to be running.  Defaults to 0.
info #
info The results are reported in the prTable section of the UCD-SNMP-MIB tree
info Special Case:  When the min and max numbers are both 0, it assumes
info you want a max of infinity and a min of 1.
question 1 Name of the process you want to check on
question 2 Maximum number of processes named '$1' that should be running [default = 0]
question 3 Minimum number of processes named '$1' that should be running [default = 0]

token disk
info Check for disk space usage of a partition.
info The agent can check the amount of available disk space, and make
info sure it is above a set limit.  
info
info # disk PATH [MIN=100000]
info #
info # PATH:  mount path to the disk in question.
info # MIN:   Disks with space below this value will have the Mib's errorFlag set.
info #        Can be a raw byte value or a percentage followed by the %
info #        symbol.  Default value = 100000.
info #
info The results are reported in the dskTable section of the UCD-SNMP-MIB tree
question 1 Enter the mount point for the disk partion to be checked on
question 2 Enter the minimum amount of space that should be available on $1

token load
info Check for unreasonable load average values.
info Watch the load average levels on the machine.
info
info # load [1MAX=12.0] [5MAX=12.0] [15MAX=12.0]
info #
info # 1MAX:   If the 1 minute load average is above this limit at query
info #         time, the errorFlag will be set.
info # 5MAX:   Similar, but for 5 min average.
info # 15MAX:  Similar, but for 15 min average.
info #
info The results are reported in the laTable section of the UCD-SNMP-MIB tree
question 1 Enter the maximum allowable value for the 1 minute load average
question 2 Enter the maximum allowable value for the 5 minute load average
question 3 Enter the maximum allowable value for the 15 minute load average
validanswer 1 ^[\d\.]+$
validanswer 2 ^([\d\.]+|)$
validanswer 3 ^([\d\.]+|)$

token file
info Check on the size of a file.
info Display a files size statistics.
info If it grows to be too large, report an error about it.
info
info # file /path/to/file [maxsize_in_bytes]
info #
info #   if maxsize is not specified, assume only size reporting is needed.
info #
info The results are reported in the fileTable section of the UCD-SNMP-MIB tree
question 1 Enter the path to the file you wish to monitor
question 2 Enter the maximum size (in bytes) allowable for $1
