What is SuperAgent?

A server side appliance that will… Passively analyze all TCP applications 24x7 Isolate performance components by

Server Client (network) Application

Analyze N-Tier environments

Does not require client or server agents!

Automated Performance Management

SLA Monitoring – Easily determine if applications are meeting their availability and performance SLA requirements.

Intelligent Baselines – Determine expected network and server performance by analyzing recent and historical trends

Incident Detection Engine - Identifies performance issues as they occur, creating a record of the incident and automatically launching an investigation into cause including a packet capture of the offending situation.

Investigations – Gather device-specific and infrastructure performance data at the time a problem is occurring, or on demand.


SuperAgent & SLA’s

Passive, server side monitoring allows for measurement of all user traffic for compliance

Single or dual level SLA’s supported SLA measurement available for

three distinct metrics: Total Transaction Time Server Response Time Network Round Trip Time

Availability SLA’s

Performance SLA’s

Monitor Compliance/Violations

Schedule Reports for Management


High Level View - Management Summary

A quick high level report will show how SLAs are being met by application for a specific time period -

In this case one month.


Application Summary

The next level of detail shows that PeopleSoft was outside of it’s first level SLA criteria.


Application Detail with Violations by Day

By drilling in on the individual days, it is possible to see on which days SLA’s were exceeded.

The metrics reported can be either transaction time, network round-trip time or server delay

Each tab provides a view by Day, Client region or server


Detail with Violations by Client Region

It is also possible to see which geographic areas were exceeding these SLA boundaries.


Response Time Analysis - Components

• Server Delay – Amount of time it takes for the server to begin responding to a request.

• Data Transfer Delay – Amount of time from when the server starts responding until it finishes sending data for a request.

• Retransmission Delay – Represents the additional delay in the Network Round Trip time due to retransmissions.

• Network Round Trip Time – Amount of time it takes for a packet to traverse the network.

Then we brake the Response time into its components to identify the root cause.


Performance Maps - Response Time Insight & Baselines

Network Round Trip Time: Amount of timeit takes for a packet to traverse the network.Data Transfer Time: Amount of time it takes

the server to send all the requested data

Server Response Time: Amount of time it takes for the server to begin responding to a request

Total Transaction Time= SRT + DTT + RT + NRTT


Trends- up to 13 Months!

The 8-hour view uses 5 minute intervals and is the most granular standard time period. This is often used for detailed problem analysis in conjunction with drilling down on servers and client regions

The daily view uses 15 minute intervals and is useful for determining if a problem is short or long term, and if it repeats over the course of the day. It is also useful for comparing performance during business hours to the overnight/batch period


Case Study 1 – Isolate the Problem

Issue:

‣ Users of the PeopleSoft Application are experiencing poor response times over the last week and complaining that the network is slow.

‣ Engineers did not know if :

- Application settings were changed ?- They had a server resource issue ?

- Bandwidth needs to be upgraded ?


Case Study 1 – Resolve the Problem

Result:

SuperAgent detects the server slowdown

SuperAgent launches an SNMP poll

Engineer found a backup process running during business hours

Server Team rescheduled the back up process and performance was restored

Avoided unnecessary investments – such as bandwidth upgrades!
