5. IT Operations needs analytics to predict,
to search and to optimize
• How can we get early warning of failures in my critical retail applications?
Predict
• Can we predict/project failure occurrences for specific asset types?
• Can I predict which KPIs are going to cause application issues without manually configuring
thresholds? I have 100s of thousands of KPIs.
• I want to predict my online banking outages and take corrective actions before customers hit
them.
• What is driving my high maintenance costs and what can I do to address this?
• How do we make sense out of the terabytes of metric and log data that is generated by
our applications and the infrastructure on which they run to isolate problems and reduce
downtime?
Search
• How can I reduce reserved material inventory due to work order backlog?
• Can I use analysis of my channel traffic analysis to achieve improved customer insight
and intelligence?
• “What-if” we change our preventive maintenance strategy?
• Help me track capacity and performance of applications & services in cloud / virtual
environments, when do I need to add more capacity?
• Show me how to reduce cost of running my virtual infrastructure & making it more
compliant with best practices.
Optimize
• How should I plan maintenance to efficiently keep my assets operational, given what
I know today about my six month resource availability.

15. Taking Full Advantage of Machine Data Requires New Thinking
Machine Data Characteristics
From variety of complex systems with complex formats – no
standards
May not always have context
Structured and unstructured data
Extremely large volumes of data
Streaming data as well as data at rest
Time sensitive - agile in interpretation and ability to respond
Requires sophisticated text analysis
Adaptive/dynamic algorithms to efficiently process data
Large scale indexing

16. Taking Full Advantage of Machine Data Requires New Thinking
Correlation across different data sets and/or different
environments
Data may need to be enriched or transformed to provide proper
context
Causal analysis (if problem on Tuesday, what happened on
Monday to cause this)
Pattern analysis
Time and spatial based analysis
Unique Visualization/UI needs based on data type and
industry/application
Sophisticated search capabilities.

17. Customer Usage Pattern of Log Analysis with
MDA
Step 1:
−
“What is happening in my systems?”
Step 2:
−
“Let me try to use my experience to correlate the events and
sequence”
Step 3:
−
“I need a tool to do Step 2 – I have too many systems and too
many logs”
Step 4:
−
“I need to combine with my system KPI data and monitor / report
in a dashboard. Provide possible solutions to the problem /
anomaly”
Step 5:
−
“I need to predict the behavior when I make changes, add error
codes. or add new systems”

18. Step 1: What is happening in my system?
This is accomplished get all the log data, extract, parse, index
and search through a faceted interface.
This is also the phase where basic event level metrics – max,
min, counts, builtin range metrics, alerts when KPIs are not in
range – are desired and tested.
Dashboards that are dynamic and actionable in sync with the
searches are highly desirable.
The MDA provides the Faceted Search interface.
KEY TECHNOLOGIES – Text Analytics, Faceted Search, BI

19. Step 2: Let me correlate events
In this phase, the customer performs searches and endeavors
to make sense of the events and sequences
−
We usually work side by side with the customer in this stage
−
We extract the vital tribal knowledge and applications in the
domain.
−
We log their “experiential” notions of event sequences and
correlations – this is essential to verify results when the user
wants to go to Step 3.
KEY TECHINOLOGIES – Big Sheets

20. Step 3: I have too many systems and logs to
correlate
In this phase, the customer essentially wants to find
relationships and patterns of occurrence between log events
across systems and applications.
The MDA provides uses sessionization and sequence mining
capability to accomplish this step.
KEY TECHNOLOGIES – Text Analytics, Machine Learning

21. Step 4: Combine with my KPI, Topology data
Once Step 3 is completed, the integration with the KPI,
topology, and monitoring data is possible.
This step allows us to expose the capabilities to the Network
Operator and end user.
KEY TECHNOLOGIES – Data Joins, SQL/JAQL, Big Sheets,
Reporting Dashboards

22. Step 5: Predict events based on patterns
The more advanced customers and network operators would
like to build predictive models based on the patterns they see in
the events in log data.
Customers want to build models that help with meeting
enterprise SLAs for systems
Downtime scheduling for systems is a complex problem for
most data centers.
KEY TECHNOLOGIES – Machine Learning (R, SPSS, System
ML)
