Using SUSE® Manager in Heterogeneous Environments

Automate repetitive tasks?
Generate customized reports from the data in a system?
Hook systems together that weren't built to work together?
Orchestrate several separate systems or tools?
Write your own UI because you have different needs than what the authors of the tool had in mind?
Want to create (read-only) dashboards, maybe even for mobile devices?
Want to ...

Then You Need APIs!

Objectives of This Session:
• Present some typical real-life scenarios that you could run into as well
• Demonstrate the power of using APIs and other ways of integration in SUSE Manager
• Provide starting points and hints for your own work
Not:
• A ready to run solution
• Comprehensive API tutorial (just the tip of the iceberg, much more to discover below sea level)
Almost no SUSECon talk can get awaywithout mentioning ...

How you can talk to yourSUSE Manager server
32
• spacewalk-reports
• Nagios/Icinga Monitoring integration
• spacecmd
• XML-RPC API
• SQL

Using SUSE Managerwith Nagios or Icinga
https://wiki.microfocus.com/index.php/SUSE_Manager/Nagios
35
Spacecmd
• Can be used interactively or in shell scripts
• Ideal for “maintenance tasks” like creating a new user
• Not so ideal for longer scripts
SUSE® Manager API ...
37
SUSE® Manager API
• The SUSE Manager API uses XML-RPC.
• Authentication is done by requesting a session key with the “auth.login” method call
Documentation:https://www.suse.com/documentation/suse_manager/• API Reference
• Manager Quick Start Guides and reference documentation
38
We Are Going To Use Python Because ...
• xmlrpc support is built in
• http and url handling built in
• OBS client API is usable as aPython module
• optional: python-requests module
Scripting can be done in other programming languages of your choice, like
‒ Perl
‒ Ruby
‒ Java
39
Connecting to SUSE® Manager
#!/usr/bin/env python
import xmlrpclib
url = "https://servername/rpc/api"
user = "username"
password = "password"
api = xmlrpclib.Server(url, verbose=0)
session = api.auth.login(user, password)
print api.user.listUsers(session)

• Nagios/Icinga Monitoring integration
• spacecmd

• SQL
Don't do that!

Ideas for SUSE Manager Integration ...
SUSEManager
Directories (SLEPOS, 3rd Party)(LDAP, Active Directory)● Users● Systems● Configuration● Topology
Configuration ManagementDatabases(CMDB), e.g. ServiceNow● Systems● Inventory● Configuration● Topology
VirtualizationPublic or Private Cloud(e.g. VMware vCenter,OpenStack, AWS)● Systems● Topology
Monitoring (e.g. Icinga, Nagios)● Systems● State● Configuration sync● Read-only dashboards (Splunk!)
externalConfiguration ManagementSystems (Puppet, Chef, ...)● Act as an “External Node Qualifier”
OS and Container Build Systems● Provide templates and repositories● Trigger rebuilds
45
Salt ...
46
What is Salt?
• A configuration management system:“I want to keep lots of systems in defined states!”
• A (distributed) remote execution system:“Run this command on lots of systems and report the results back to me!”
• SUSE Manager 3 will use Salt• Salt will be added to SUSE Linux Enterprise Server
11 and 12 (in addition to Puppet and CFengine)
47
Why Salt?
• Combines remote execution framework (like Ansible) with declarative configuration management (like Puppet/Chef) in one tool
• Can be used without a server (“master-less”), via ssh, or with a “master” server and a “minion” daemon
• Distributed architecture fits well into use cases in retail, hybrid cloud etc.
• Fast and highly scalable
• Easy to extend (with many existing plugins for OpenStack, Docker, etc.)
• Large and rapidly growing community
Outlook: “Best Practice Exchange”?
49
Long Term Vision: Service Templates
• The vision is to ultimately be able to provide “Service Templates” for the “Software Defined Datacenter” that describe
‒ all the Linux images used in a setup that delivers a certain software service
‒ all the configuration (hardware and software, from network to credentials)
‒ SLAs (HA, sizing of hardware, performance scaling)
• Looking into TOSCA standard andHeat (OpenStack) … and of course Salt
SUSE Manager andMicrosoft System Center
51
Heterogeneity is a Fact of Life
52
Mixed Windows and Linux Infrastructures Too
53
At a Glance
• Works with System Center Ops Manager 2007 R2, 2012, and 2012 R2
• Requires installed SUSE Manager
54
SUSE Manager Management Packfor Microsoft System Center
• Connects Microsoft System Center Operations Manager to SUSE Manager
• Provides management of Windows and Linux patches from one console
• Automates Linux patch updates from System Center
• Lists Linux servers entitled for selected critical and optional updates and patches
• Schedules maintenance window to run updates on a specific Linux server or a group of Linux servers
• Patches SUSE Linux Enterprise Server and RHEL when combined with Expanded Support
55
SUSE Manager Management Pack
Streamline Multi-platform Management
• Supports management of Windows and Linux patches from the same console
• Automates Linux patch updates from System Center
• Maximizes investment in existing infrastructure, including software, hardware, and IT administration expertise
• Lowers risk of failure because of a missed patch
• Helps to ensure compliance
INCREASED EFFICIENCY REDUCED COST MINIMIZED RISK
56
Bottom Line
• The Management Pack brings simplicity to IT management
• Makes lives of admins easier
• Demo and questions
57
Wrapping Up...
Thank you.

➔ If you haven't yet, you should reallystart looking into usingSUSE Manager's XML-RPC API!
➔ For new projects, considerstarting with Salt!
➔ If you have Microsoft SCOM, the Management Pack delivers integration out of the box!
Thank you.
