What is and why use monitoring

§ Monitoring definition
– Monitoring is a continuous process to keep eye on systems or scheduled
activities.
– Its aim is to obtain real-time information to ease the overview or action in
certain cases.
– Monitoring varies from to time, project to project and activity to activity.
– Can be Real-time or Event driven

§ Why use monitoring
– to be aware of the state of a system
– to observe a situation for any changes which may occur over time
– to react on unpredicted or predicted situations

Business Monitoring and Technical Monitoring

§ Business monitoring
– Monitoring and aggregation of data, like data input values, data
changes, paths in application depending of data, or human
centric data.

§ Business activity monitoring (BAM)
– Business Monitoring of data from business processes.

§ Technical monitoring
– Monitoring for supporting and controlling any system,
application, or service to ensure that they run as designed and
as expected.




§ Borders between both monitoring
intentions are smooth

§ Technical Monitoring and Business
Monitoring may overlap in some Business Monitoring
cases
overlap
§ In most cases doing business
monitoring, dealing with sensitive Technical Monitoring
or critical data, technical monitoring
may be applied as well



Monitoring types

§ Business Monitoring - Near-time Monitoring
– displaying measurements or KPIs (Key Performance Indicators) to a
business process controller / management
• measurements with a Target Near-time Monitoring
• applying a range or SLA

§ Technical Monitoring - Real-Time Monitoring
– displaying real-time technical information
• to IT Support / Maintenance / Administration experts
– acting on specific events or situation changes
• Event driven monitoring

Anticipating Virtualization Challenges
When a virtual environment has a problem, where did it originate?
The are no “virtual performance problems”, only very real performance problems
manifested in a very complex consolidated, virtual environment.

In the Application (bad process) running

on the virtual resource?

In the Logical Partition/Machine Linux Linux

z/VSE Monitoring – Technical Monitoring

§ Real-Time Monitoring
– displaying technical information
• to IT Support/Maintenance/Administration experts

§ Event driven Monitoring
– acting on specific events or situation changes
• Event driven monitoring



z/VSE SNMP Monitoring Agent support

§ z/VSE Monitoring Agent enables customers to monitor z/VSE systems using
standard monitoring interfaces (SNMP V1)
– Available since z/VSE V4.3
– It also includes an open interface, which enables customers or vendors to use own
programs (plugins) to collect additional data

§ Data collected by the IBM provided plugins contains
– Information about the environment (e.g. Processor, LPAR and z/VM information)
– Number of partitions (static, dynamic, total, maximum)
– Partition priorities
– Number of CPUs (active, stopped, quiced)
– Paging (page ins, page outs)
– Performance counters overall and per CPU
– CPU address and status
– CPU time, NP time, spin time, allbound time
– Number of SVCs and dispatcher cycles




§ Management Information Base (MIB)
– SNMP itself does not define which information (which variables/counters) a managed
system should offer
– Rather, SNMP uses an extensible design, where the available information is defined by
management information bases (MIBs).
– MIBs describe the structure of the management data of a device subsystem
• They use a hierarchical namespace containing object identifiers (OID).
• Each OID identifies a variable (e.g. a performance counter) that can be read or set
via SNMP.

§ SNMP V1 Protocol
– Get Get the value of an object identified by its OID
– GetNext Get the value of the next object identified by an OID
– Set Set the value of an object identified by its OID (not used by z/VSE)
– Trap Asynchronous notification about something (an event)

§ Standard SNMP based monitoring tools can be used to collect, display and analyze
z/VSE performance monitoring data
– e.g. ITM (IBM Tivoli Monitoring), Velocity monitoring, Nagios (www.nagios.org)

§ z/VSE SNMP Trap client
– Sends SNMP V1 traps to inform
one or more monitoring stations or
servers about important events
– For example:
• The end of a job stream
is reached.
• An error has occurred during
a job stream



z/VSE SNMP Monitoring Agent support - Setup

To setup the z/VSE Monitoring Agent you have to do the following steps:

1. Create the configuration files
– Use skeletons IESMASCF and SKMASCFG (ICCF library 59) to create the z/VSE
Monitoring Agent configuration file
– If you want to use the System Plugin, use the skeletons IESMPSCF and SKMPSCFG
(ICCF library 59) to create the System Plugin configuration file

2. Create the startup job
– Use skeletons SKSTMAS (ICCF library 59) to create a z/VSE Monitoring Agent
startup job

3. Download the MIB (IESMPMIB.Z in PRD1.BASE) from your z/VSE system to be able to
use it with your SNMP client

1. Start the z/VSE Monitoring Agent (using the startup job), e.g. R RDR,STARTMAS



z/VSE SNMP Monitoring Agent support – Usage

Operating Monitoring Agent:

To get status information from the z/VSE Monitoring Agent, enter at the z/VSE console
msg <jobname>,data=status

Sample output:
AR 0015 1I40I READY
R1 0045 IESMA118I AGENT STATUS:
R1 0045 AGENT VERSION: 0004.3000
R1 0045 CONFIG MEMBER: DD:PRD2.CONFIG(IESMASCF.Z)

z/VSE SNMP Monitoring Agent support – Trap Client

Send a Trap (see SKSTTRAP in ICCF library 59):

* ****************************************************** *
* SNMP TRAP CLIENT sample *
* You can add one or more destinations. *
* The ADDSYSINF parameter adds system information to *
* trap packet. *
* If you specify the HELP parameter you will find a *
* detailed help and a list of all supported parameters *
* in the job listing. *
* A '*' marks lines as comments *
• ****************************************************** *
// OPTION SYSPARM='00'
// EXEC IESMTRAP
DEST=192.168.1.55
DEST=myserver1:162
OID=1.2.3.4
MSG=This is a test
ADDSYSINF
/*
Two destinations
for the TRAP

Add System Info to This is the trap
the Trap message message


z/VSE Event Monitoring – Trap Client Enhancements z/VSE 5.1

§ z/VSE 4.3: SNMP traps (events) can be sent from batch jobs only
– via // EXEC IESMTRAP in a batch job

§ z/VSE 5.1 adds the possibility to send SNMP traps from within customer programs
– Using the new SNMP Trap API
– Send traps from within batch programs (LE enabled, i.e. COBOL, PL/1, C)
– Send traps from within a CICS application (EXEC CICS LINK interface)
