ECScmdb

CLI Version

cmdb:     ecscmdb(1.6.29), ecspylibs(1.1.18)
cmdbdiff: ecscmdb(1.6.29), ecspylibs(1.1.18)

Summary of commands

cmdb:     Download the devices in the OpenManage database into a
          spreadsheet, one work sheet for each device.

cmdbdiff: Compare two cmdb spreadsheets for differences.

Assumptions

The ecscmdb user needs to know:

• how to run commands in a Linux environment.
• how to install python packages in a virtualenv.
• how to run python commands in a virtualenv.
• how to configure yaml files.
• some basic understanding of jinja2 variable used in the yaml file.

Installation

It is best to create a dedicated python virtualenv to install ecscmdb 
into so as not to interfere with any other python packages installed 
on your system.

# virtualenv .venv
# . .venv/bin/activate
# pip install ecscmdb

Setup

cmdb

Before cmdb can be used to gather OpenManage data, the files cmdb.yml 
and cmdb.pw must be created.  They are both located in the directory 
etc/ecscmdb, which is relative to the virtualenv directory ecscmdb was 
installed in.

cmdb.yml

cmdb.yml is a yaml file. The yaml file can have multiple "config" 
sections defined within it.  There must be at lease one config section.
Each config secion has the following fields:

name:       The name of the config section (optional).
pw:         The location of the cmdb password file relative to 
            virtualenv base directory cmdb was installed in.
log_level:  The python log level cmdb will run at.  Must be one of 
            DEBUG, INFO, WARNING, ERROR, CRITICAL, or TRACE.
log_dir:    The location of the cmdb log directory relative to 
            virtualenv base directory cmdb was installed in. 
OME_Login:  The User ID of the OpenManage server that will be used 
            to gather the data.
poolsize:   The number of python ProcessPoolExecutor pools that will
            be used to gather the OpenManage data.
output:     The location of the cmdb output file that the cmdb 
            spreadsheet will be written to.  The name of the file can
            include the jinja2 variable "{{ TOD }}" to include the 
            current date and time.

In addition to the config section(s), the yaml file also must include 
the yaml variable "section:" which indicates which of the config sections
to process.

cmdb.yml example file

Here is an example cmdb.yml file with two config sections.  Because the
"section:" variable is set to 2 in this example the second section, with 
name "Configuration file Testing", will be used.

---
section: 2
config:
  - name: Configuration file Production.
    pw: etc/ecscmdb/cmdb.pw
    log_level: warning
    log_dir: log
    OME_Login: CMDB
    poolsize: 12
    output: output/OpenManage-cmdb.{{ TOD }}.xlsx
  - name: Configuration file Testing.
    pw: etc/ecscmdb/cmdb.pw
    log_level: TRACE
    log_dir: log
    OME_Login: CMDB
    poolsize: 24
    output: output/OpenManage-test-cmdb.{{ TOD }}.xlsx
...

cmdb.pw

cmdb.pw is a python AES encripted password file.  It must contain the
following two entries: 

1. A key that matches the OME_Login variable from the cmdb.yml file. The value of the entry is the password for that user.
2. A key named "OMEHost" (case-sensitive string). The value of the entry is the URL for the OpenManage host.

Adding or updating an entry in the cmdb.pw file

Execute "cmdb --add=STRING", where STRING is the key to be created or
updated.  cmdb will then prompt for the value for the given key.  The 
entries are encripted and stored in the cmdb.pw file.

Example

# cmdb --add=xyzzy
Enter password for user 'xyzzy':
#

Deleting an entry from the cmdb.pw file

Execute "cmdb --delete=STRING", where STRING is the key to be deleted.
The entries will be deleted without prompting.

Example

# cmdb --delete=xyzzy
#

List the keys or keys/values stored n the cmdb.pw file

Execute "cmdb --list" to list all of the keys in the cmdb.pw file, or
"cmdb --list --verbose" to list both the keys and the values for each 
key.

Examples

# cmdb --list
# cmdb --list --verbose

cmdbdiff

Before cmdbdiff can be used to compare two OpenManage spreadsheets, 
created using the cmdb command, the file cmdbdiff.yml must be created. 
This file is located in the directory etc/ecscmdb, which is relative 
to the virtualenv directory ecscmdb was installed in.

cmdbdiff.yml

cmdbdiff.yml is a yaml file. The yaml file can have multiple "config" 
sections defined within it.  There must be at least one config section 
in it.  In addition to the config section(s), the yaml file also must 
include the yaml variable "section:" which indicates which of the config 
sections to process.st be at lease one config section.  Each config 
secion has the following fields:

name:                       The name of the configuration section 
                            (optional).
admin:                      The Admin managing cmdbdiff.
    name:                   The Admin name.
    email:                  The Admin email address.
    phone:                  The Admin phone number.
log_level:                  The python log level cmdb will run at.  
                            Must be one of DEBUG, INFO, WARNING, ERROR, 
                            CRITICAL, or TRACE.
log_dir:                    The location of the cmdb log directory 
                            relative to virtualenv base directory cmdb 
                            was installed in.
report:                     The location of the cmdbdiff report file 
                            that cmdbdiff writes to.  The name of the 
                            file can include the jinja2 variable 
                            "{{ TOD }}" to include the current date and 
                            time.
