########################################################################### # # snmpd.conf # # - created by the snmpconf configuration program # ########################################################################### # SECTION: Access Control Setup # # This section defines who is allowed to talk to your running # snmp agent. # rocommunity: a SNMPv1/SNMPv2c read-only access community name # arguments: community [default|hostname|network/bits] [oid] rocommunity public ########################################################################### # SECTION: Monitor Various Aspects of the Running Host # # The following check up on various aspects of a host. # proc: Check for processes that should be running. # proc NAME [MAX=0] [MIN=0] # # NAME: the name of the process to check for. It must match # exactly (ie, http will not find httpd processes). # MAX: the maximum number allowed to be running. Defaults to 0. # MIN: the minimum number to be running. Defaults to 0. # # The results are reported in the prTable section of the UCD-SNMP-MIB tree # Special Case: When the min and max numbers are both 0, it assumes # you want a max of infinity and a min of 1. proc httpd 10 3 proc vsftpd 2 # disk: Check for disk space usage of a partition. # The agent can check the amount of available disk space, and make # sure it is above a set limit. # # disk PATH [MIN=100000] # # PATH: mount path to the disk in question. # MIN: Disks with space below this value will have the Mib's errorFlag set. # Can be a raw byte value or a percentage followed by the % # symbol. Default value = 100000. # # The results are reported in the dskTable section of the UCD-SNMP-MIB tree disk / # load: Check for unreasonable load average values. # Watch the load average levels on the machine. # # load [1MAX=12.0] [5MAX=12.0] [15MAX=12.0] # # 1MAX: If the 1 minute load average is above this limit at query # time, the errorFlag will be set. # 5MAX: Similar, but for 5 min average. # 15MAX: Similar, but for 15 min average. # # The results are reported in the laTable section of the UCD-SNMP-MIB tree load 12 12 12 load 5 5 5 ########################################################################### # SECTION: System Information Setup # # This section defines some of the information reported in # the "system" mib group in the mibII tree. # syslocation: The [typically physical] location of the system. # Note that setting this value here means that when trying to # perform an snmp SET operation to the sysLocation.0 variable will make # the agent return the "notWritable" error code. IE, including # this token in the snmpd.conf file will disable write access to # the variable. # arguments: location_string syslocation "Saint Paul, MN, USA" # syscontact: The contact information for the administrator # Note that setting this value here means that when trying to # perform an snmp SET operation to the sysContact.0 variable will make # the agent return the "notWritable" error code.
