The document discusses embedding existing heterogeneous monitoring techniques into a lightweight, distributed integration platform. It aims to unify accumulated monitoring data from different sources by wrapping sensor scripts with adapters and integrating them into the Remote Component Environment (RCE). This allows monitoring data to be collected from distributed systems and provided through a centralized, unified interface while reusing existing sensor scripts. The environment is being implemented on top of RCE to provide clients like GUIs and alert systems with integrated access to monitoring data.

3. Motivation
Monitoring in HPC/CAE Environments
In CAE environments, a lot of software components do monitoring!

4. Motivation
Different Purposes for Monitoring
Resource Management
Monitoring Resources like Load, Licenses, …
Examples: Grid Engine, PBS, Platform LSF
Health Management
Monitoring Resources like Load,
Heat, SMART-Status
Examples: Ganglia, Nagios
Resource Planning
Esp. License Monitoring
Examples: We have created License Monitoring and Accounting
Solutions for some of our customers.

5. Motivation
A typical setup has 3 Software Components that are monitoring
All with different types of Sensors
All with different administrative and user interfaces
Some Resources are monitored more than once (Load, Licenses)
Let‘s do it once!
But allow reusability of existing solutions!

6. Monitoring Techniques
Ganglia (gmetric)
Basically, a Sensor-Script for Ganglia just reports a simple value.
May be written in sh, perl, python, …
Whatever you/your Administrators like!
#!/bin/sh
echo 60.3
# gmetric --name temperature --value
> $(cputemp) --type float --units Celsius
There are a lot of these scripts available on the internet for free.
Measure Infiniband performance
Temperatures via IPMI
…

7. Monitoring Techniques
Grid Engine (Load Sensors)
We use a lot of scripts for the Grid Engine to make the scheduler aware
of license usage.
A bit more complicated, but again: may be written in any language.
#!/bin/sh
while read x ; do
echo begin
echo “global:lic_abq_free:5“
echo “global:lic_abq_used:8“
echo “global:lic_abq_total:13“
echo end
done
Platform LSF and PBS use similar mechanics.
Administrators know how to write these scripts.
We think that acceptability is a key factor for success!

8. Realizing the Monitoring Environment
Requirements
Collect heterogeneous monitoring data from distributed hosts
Provide them centralized via one unified interface
Reuse existing sensor scripts
Solution
Unify accumulated data by wrapping the scripts with adapters
Embed the scripts (i.e. the adaptors) in an integration platform
Make use of the platform‘s infrastructure to collect the data
Realize an embedded component providing the data

9. Realizing the Monitoring Environment
Unify the Heterogeneous Monitoring Data
Wrapping each sensor script with an adapter which
Executes the script
Transforms the data
Provides them via one unified interface

10. Realizing the Monitoring Environment
Integration Platform
Unified environment with base software components
Data management, distribution, privilege management, ...
Integrating diverse and specific applications
Benefit
Integrated applications simply use already realized software components
Enables basically independent applications to
Interact
Operate on same data
Base software components are realized only once
