  3. grapher - a generic graphing tool

    4. The Grapher lets you plot a interactive XY Line graph for more than one set of data to visualize the change over a period of time.

    The grapher may be invoked using the following command line options:

    • --type graph/barchart

      Specify the type of pictorial representation to be used to depict data. Currently only "graph" option may be used to represent data as XY Line graph.

    • --series *

      Specify the characteristics of a series with this option. Color may be any one of following green, blue, red or yellow. Symbol may be diamond, circle, triangle or square and the label is brief description about the series which used in legend for the series in the graph window.

    • --source

      Specify the filename for which the grapher reads the data to be plotted. The file has text in the following format for each data point in the series.

      cmd series-id x-axis-value y-axis-value
      e.g PLOT 1 0 2
      (0,2) is to be plotted on series 1 in the graph.

      Currently two commands are supported PLOT and EXIT. EXIT command is without any arguments.

    The following options are optional.

    • --scroll

      This option may be used to display an horizontal scrollbar in the graph window.

    • --xmin n

      Specifies the minimum limit of x axis. Any x coordinate of data point less than n is not displayed.

    • --xmax n Specifies the maximum limit of x axis. Any x coordinate of data point greater than n is not displayed.

    • --ymin n

      Specifies the minimum limit of y axis. Any y coordinate of data point less than n is not displayed.

    • --ymax n

      Specifies the maximum limit of y axis. Any y coordinate of data point greater than n is not displayed.

  4. oidinfo - display OID information

    5. This utility gives information about a MIB object either by name or OID. The information returned is in internal format, but can be useful to learn more about a MIB object.

    Examples: 

    ultra5[1556] oidinfo ifOperStatus
INFO  08/25.08:47:22 - NAME ifOperStatus = 1.3.6.1.2.1.2.2.1.8
INFO  08/25.08:47:22 - MIB = IF-MIB
parent = ,	subid = 8, name = ifOperStatus, access = 1
  type = 3
1, up
2, down
3, testing
4, unknown
5, dormant

ultra5[1557] oidinfo 1.3.6.1.2.1.2.2.1.8
INFO  08/25.08:47:41 - OID 1.3.6.1.2.1.2.2.1.8 = ifOperStatus
INFO  08/25.08:47:41 - MIB = IF-MIB
parent = ,	subid = 8, name = ifOperStatus, access = 1
  type = 3
1, up
2, down
3, testing
4, unknown
5, dormant

  5. walkfile converters

    6. The convertwalk utility converts walkfiles from 3rd party packages into a format that the MIMIC Recorder understands. MIMICView invokes this utility from the Walkfile Importer dialog whereever walkfiles are accessed, eg. in the Simulation->Record dialog, or in the Discovery Wizard. It will not convert again a walkfile that has already been converted.

    Additionally, we provide some obsolete shell scripts to convert files. These scripts convert walkfiles from 3rd party packages into a format that the MIMIC Recorder understands. The scripts live in the common/ directory.

    The following formats can be converted:

    • HP Openview 

      % ./hpov.csh
Usage: ./hpov.csh infile outfile [start]

    • HP Netmetrix 

      % ./netmetrix.csh
Usage: ./netmetrix.csh infile outfile [start]

    • UCD snmpwalk 

      % ./ucd.csh
Usage: ./ucd.csh infile outfile [start]

    • NetHealth 

      % ./nethealth.csh
Usage: ./nethealth.csh infile outfile [start]

  8. SNMPv3 Configuration

    9. The snmpv3conf utility allows to list / modify SNMPv3 USM and VACM configurations.

    By default, when changing any file, this utility performs file versioning, ie. it saves away the old file in a timestamped folder under OLD/ .

    USM configuration

    The USM configuration allows to specify the users of the User-based Security Model that governs access to SNMPv3 agents in MIMIC. Each agent can have its own USM file (or they can share a USM file). The following commands allow to list/modify USM files in MIMIC.

    This lists the USM files: 

    % ./snmpv3conf --list-usm
INFO - list of USM config files
 v3usm.conf shared

    This copies the sample v3usm.conf to my own USM file, so that we don't affect the original: 

    % ./snmpv3conf --config v3usm.conf --copy-config myusm.conf
INFO - copied config v3usm.conf to myusm.conf

% ./snmpv3conf --list-usm
INFO - list of USM config files
 v3usm.conf shared
 myusm.conf private

    This lists both enabled and disabled users. Enabled users control access to the agent's MIB, disabled users do not. You can enable disabled users and vice versa. 

    % ./snmpv3conf --config myusm.conf --list-users
INFO - list of users in config myusm.conf
 user1 user2 user3 user4 user5 user6 user7 user11 user12 user13 user14 user15

 user42   user42       SHA-512     1234567890abcdef AES-256 1234567890abcdef

    This changes one of the users. All attributes except for userName can be changed. 

    % ./snmpv3conf --config myusm.conf --user user1 --details
INFO - details for user user1 in config myusm.conf
 userName: user1
 securityName: user1
 authProtocol: noAuth
 authKey: 0
 privProtocol: noPriv
 privKey: 0
 disabled: 0

% ./snmpv3conf --config myusm.conf --user user1 --change "authProtocol: HMAC-MD5-96" \
--change "authKey: somepassword" --no-versioning
INFO - change authProtocol: HMAC-MD5-96 for user user1 in config myusm.conf
INFO - change authKey: somepassword for user user1 in config myusm.conf

% ./snmpv3conf --config myusm.conf --user user1 --details

 userName: user1
 securityName: user1
 authProtocol: HMAC-MD5-96
 authKey: somepassword
 privProtocol: noPriv
 privKey: 0
 disabled: 0

    This adds a new user and changes a couple of attributes: 

    % ./snmpv3conf --config myusm.conf --add-user user16 --change "authProtocol:HMAC-SHA-96" \
--change "authKey: 3248979837598743"
INFO - add new user user16 in config myusm.conf
INFO - change authProtocol:HMAC-SHA-96 for user user16 in config myusm.conf

 securityName: user16
 authProtocol: HMAC-SHA-96
 authKey: 3248979837598743
 privProtocol: noPriv
 privKey: 0
 disabled: 0

    Notice, this could have also been achieved by copying existing user user3 and changing the authKey attribute. We will create user17 that way: 

    % ./snmpv3conf --config myusm.conf --add-user user17 --from user3 --change \
"authKey: 3248979837598743"
INFO - add new user user17 from user3 in config myusm.conf
INFO - change authKey: 3248979837598743 for user user17 in config myusm.conf

% ./snmpv3conf --config myusm.conf --user user17 --details                      
INFO - details for user user17 in config myusm.conf
 userName: user17
 securityName: user17
 authProtocol: HMAC-SHA-96
 authKey: 3248979837598743
 privProtocol: noPriv
 privKey: 0
 disabled: 0

    VACM configuration

    The VACM configuration allows to specify the local datastore of the View-based Access Control Model that governs access to SNMPv3 agents in MIMIC. Each agent can have its own VACM file (or they can share a VACM file). The following commands allow to list/modify VACM files in MIMIC.

    This lists the VACM files: 

    % ./snmpv3conf --list-vacm
INFO - list of VACM config files
 v3vacm.conf shared

    This copies the sample v3vacm.conf to my own VACM file, so that we don't affect the original: 

    % ./snmpv3conf --config v3vacm.conf --copy-config myvacm.conf
INFO - copied config v3vacm.conf to myvacm.conf

% ./snmpv3conf --list-vacm
INFO - list of VACM config files
 v3vacm.conf shared
 myvacm.conf private

    This lists both enabled and disabled groups. Enabled groups control access to the agent's MIB, disabled groups do not. You can enable disabled groups and vice versa. 

    INFO - list of groups in config myvacm.conf
 group1 group2 group3 group4 group5 group6 group7 group11 group12 group13 group14

    This changes one of the groups. All attributes except for the group name can be changed. 

    % ./snmpv3conf --config myvacm.conf --group group2 --details
INFO - details for group group2 in config myvacm.conf
 group: group2

% ./snmpv3conf --config myvacm.conf --group group2 --change securityName:user3

% ./snmpv3conf --config myvacm.conf --group group2 --details
INFO - details for group group2 in config myvacm.conf
 group: group2
 securityModel: usm
 securityName: user3
 disabled: 0

    This adds a new group and changes its securityName attribute: 

    % ./snmpv3conf --config myvacm.conf --add-group mygroup --change securityName:user3
INFO - add new group mygroup in config myvacm.conf
INFO - change securityName:user3 for group mygroup in config myvacm.conf

% ./snmpv3conf --config myvacm.conf --group mygroup --details
INFO - details for group mygroup in config myvacm.conf
 group: mygroup
 securityModel: usm
 securityName: user3
 disabled: 0

    Notice, this could have also been achieved by copying existing user group3. We will create mygroup2 that way: 

    % ./snmpv3conf --config myvacm.conf --add-group mygroup2 --from group3
INFO - add new group mygroup2 from group3 in config myvacm.conf

% ./snmpv3conf --config myvacm.conf --group mygroup2 --details
INFO - details for group mygroup2 in config myvacm.conf
 group: mygroup2
 securityModel: usm
 securityName: user3
 disabled: 0

    This lists both enabled and disabled access clauses. Enabled access clauses control access to the agent's MIB, disabled clauses do not. You can enable disabled access clauses and vice versa.

    This changes the access clause for group group1. All attributes except for the group name can be changed.

    This adds a new access clause for the mygroup group added previously, and changes its securityLevel, writeView and notifyView attributes: 

    % ./snmpv3conf --config myvacm.conf --add-access mygroup --change securityLevel:authNoPriv \

    Notice, this could have also been achieved by copying existing access clause for group2. We will create mygroup2 that way: 

    % ./snmpv3conf --config myvacm.conf --add-access mygroup2 --from group2
INFO - add new access mygroup2 from group2 in config myvacm.conf

% ./snmpv3conf --config myvacm.conf --access mygroup2 --details

    This lists both enabled and disabled access clauses. Enabled access clauses control access to the agent's MIB, disabled clauses do not. You can enable disabled access clauses and vice versa.
