snmpstatus(1)


NAME

   snmpstatus  -  retrieves  a  fixed set of management information from a
   network entity

SYNOPSIS

   snmpstatus [COMMON OPTIONS] [-Cf] AGENT

DESCRIPTION

   snmpstatus is an SNMP  application  that  retrieves  several  important
   statistics from a network entity.

   AGENT  identifies a target SNMP agent, which is instrumented to monitor
   the given objects.  At  its  simplest,  the  AGENT  specification  will
   consist  of  a  hostname  or  an  IPv4 address.  In this situation, the
   command will attempt communication with the agent,  using  UDP/IPv4  to
   port 161 of the given target host.

   See  the snmpcmd(1) manual page for a full list of the possible formats
   for AGENT.

   The information returned is:

          The IP address of the entity.
          A textual description of the entity (sysDescr.0)
          The uptime of the entity's SNMP agent (sysUpTime.0)
          The sum of received packets on all interfaces (ifInUCastPkts.* +
          ifInNUCastPkts.*)
          The    sum    of   transmitted   packets   on   all   interfaces
          (ifOutUCastPkts.* + ifOutNUCastPkts.*)
          The number of IP input packets (ipInReceives.0)
          The number of IP output packets (ipOutRequests.0)

   For example:

   snmpstatus -c public -v 1 netdev-kbox.cc.cmu.edu

   will produce output similar to the following:

   [128.2.56.220]=>[Kinetics FastPath2] Up: 1 day, 4:43:31
   Interfaces: 1,  Recv/Trans packets: 262874/39867 | IP: 31603/15805

   snmpstatus  also  checks  the  operational  status  of  all  interfaces
   (ifOperStatus.*),  and  if  it  finds any that are not running, it will
   report in a manner similar to this:

   2 interfaces are down!

   If the network entity has an error processing the  request  packet,  an
   error  packet  will be returned and a message will be shown, helping to
   pinpoint in what  way  the  request  was  malformed.   snmpstatus  will
   attempt  to  reform  its  request  to  eliminate the malformed variable
   (unless the -Cf option is given, see below),  but  this  variable  will
   then be missing from the displayed data.

OPTIONS

   COMMON OPTIONS
          Please  see  snmpcmd(1) for a list of possible values for COMMON
          OPTIONS as well as their descriptions.

   -Cf    By default, snmpstatus will try to fix errors  returned  by  the
          agent  and  retry a request. In this situation, the command will
          display the data that it can. If the -Cf  option  is  specified,
          then  snmpstatus  will not try to fix errors, and the error will
          cause the command to terminate.
