snmpdelta - Monitor delta differences in SNMP Counter values


   snmpdelta  [  COMMON  OPTIONS ] [-Cf] [ -Ct ] [ -Cs ] [ -CS ] [ -Cm ] [
   -CF configfile ] [ -Cl ] [ -Cp period ] [ -CP Peaks ] [ -Ck ] [  -CT  ]
   AGENT OID [ OID ... ]


   snmpdelta  will  monitor  the specified integer valued OIDs, and report
   changes over time.

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

   OID  is  an object identifier which uniquely identifies the object type
   within a MIB. Multiple OIDs can be  specified  on  a  single  snmpdelta


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

   -Cf     Don't fix errors and retry the request.  Without  this  option,
           if  multiple  oids have been specified for a single request and
           if the request for one or more of  the  oids  fails,  snmpdelta
           will  retry  the  request  so that data for oids apart from the
           ones that failed will still be returned.  Specifying -Cf  tells
           snmpdelta  not  to  retry a request, even if there are multiple
           oids specified.

   -Ct     Flag will determine time interval from the monitored entity.

   -Cs     Flag will display a timestamp.

   -CS     Generates a "sum count" in addition to the individual  instance
           counts.   The  "sum  count"  is the total of all the individual
           deltas for each time period.

   -Cm     Prints the max value ever attained.

   -CF configfile
           Tells snmpdelta to read it's configuration from  the  specified
           file.   This  options  allows the input to be set up in advance
           rather than having to be specified on the command line.

   -Cl     Tells snmpdelta to write  it's  configuration  to  files  whose
           names  correspond to the MIB instances monitored.  For example,
           snmpdelta  -Cl  localhost  ifInOctets.1  will  create  a   file

   -Cp     Specifies  the  number  of  seconds  between  polling  periods.
           Polling constitutes sending a request to the agent. The default
           polling period is one second.

   -CP peaks
           Specifies  the  reporting  period in number of polling periods.
           If this option is specified, snmpdelta polls  the  agent  peaks
           number  of  times  before  reporting  the  results.  The result
           reported includes the average value over the reporting  period.
           In  addition,  the  highest  polled  value within the reporting
           period is shown.

   -Ck     When the polling period (-Cp) is an increment of 60 seconds and
           the  timestamp  is  displayed  in  the  output  (-Cs), then the
           default display shows the timestamp in the format hh:mm  mm/dd.
           This option causes the timestamp format to be hh:mm:ss mm/dd.

   -CT     Makes snmpdelta print its output in tabular form.

   -Cv vars/pkt
           Specifies  the maximum number of oids allowed to be packaged in
           a single PDU. Multiple PDUs can be created in a single request.
           The  default  value of variables per packet is 60.  This option
           is useful if a request response results in an error because the
           packet is too big.

   Note that snmpdelta REQUIRES  an argument specifying the agent to query
   and at least one OID argument, as described in  the  snmpcmd(1)  manual


   $ snmpdelta -c public -v 1 -Cs localhost IF-MIB::ifInUcastPkts.3 IF-MIB::ifOutUcastPkts.3

   [20:16:06 6/14]     158.00    158.00

   The  following example uses a number of options. Since the Cl option is
   specified, the output is sent to a file and not to the screen.

   $ snmpdelta -c public -v 1 -Ct -Cs -CS -Cm -Cl -Cp 60 -CP 60 . .
