snmpGet command

snmpGet command retrieves information in agents using SNMP protocol.

In Tivoli Netcool Performance Manager, with multiple collectors on single host we can use the snmpGet with particular collector as follows:
  1. Source dataLoad.env -i <Instance Number>:
  2. snmpGet <OPTIONS>.
    OR
    snmpGet <OPTIONS> -n <COLLECTOR_ID>.

SYNOPSIS

snmpGet <target> <oid> [-m <mibs>] [-c <readCommunity>] [-t <timeout>] [-r <tries>] 
[-F {RAW|CLEAN|MIMIC}]
[-D <debugLevel>] {-all | -n <collNumber> | [-S <server> [-P <port>]]} [-?] [--version]

Options

Table 1. Options for snmpGet command
Option Description
<target> This is the IP address or the name of the SNMP device.
<oid> This is either the dotted form of the oid, or the name.instance of the oid to read. The <oid> can contains star character '*', in this case GetNext will be used instead of Get to retrieve content of a complete table. Several <oid> can be repeated in the command, and they will all be retrieved in the same PDU whenever possible.
-m <mibs> The compiled Mib file name that contains the definition for the required oid. This is a .oid file, without path. The file is expected to be found in the SNMP dataload's mibs/oid directory.
-c <readCommunity> The read community to use to perform the action if different from the default read community configured in SNMP_CONF for that device.
-t <timeout> The SNMP timeout to use. Default value is defined in theSNMP_CONF for that device
-r <tries> The number of SNMP tries to use (1 or more). Default value is defined in the SNMP_CONF for that device
-F {RAW|CLEAN|MIMIC|PROVISO} The output format for the OIDs.
-D <debugLevel> <debugLevel> is a number between 0 and 6. 0 represents no debug, 6 is the most verbose.
-sim <simulationFile> <simulationFile> is a file, on the collector machine, that is used in place of the remote SNMP agent. This file can be obtained using a -f PROVISO on the snmpGet command.
-all All SNMP dataload currently running in the system will receive the request.
-n <collectoNumber> The request will only be sent to SNMP dataload process running collection set number <collectoNumber>.
-S <serverName> <serverName> is the name of the machine that hosts a specific SNMP dataload. If this switch is not defined, 'localhost' is assumed.
-P <portNumber> <portNumber> is the listening port number of the SNMP dataload. If this switch is not defined, the value of the DL_ADMIN_TCP_PORT environment variable will be used. If the environment variable is not defined, 3002 is assumed. If none of the -all, -n, -S and -P switches are specified, then localhost:3002 will be assumed.
