2. Task 3.3: Subtasks Specification
Task (CYFRO)
Invasive Monitoring:
‘Autonomous monitoring system for on-line and automatic
performance analysis ‘
Task (TCD)
Non-invasive Monitoring:
‘SQL-query-based tool support for non-invasive monitoring’
Task (CYFRO)
Infrastructure Monitoring:
‘Grid Jiro-based services for Grid infrastructure monitoring’
Task (ICM)
Post-processing:
‘Post-processing of Grid monitoring information’
CYFRONET is also engaged in Jiro monitoring, so we should mark it. In fact, CYFRONET
is probably to do entire work concering the Jiro monitoring.
<BAC> Sorry, this is just a misunderstanding on my part. I have now lumped ICM in under
Task 3.3.1, and changed to CYFRO – can you fix the CYFRO MM values ?
2. ICM was supposed to work on postprocessing (see slide 26 added by ICM).
Postprocessing is not considered here at all.
<BAC> It is in the slides and the SRS, but just as a black box (actually yellow).
Please suggest something.

When it comes to talk about TCD’s non-invasive monitoring – can you provide me with a simple scenario? E.g. What ‘Instruments’ can be?
<BAC> e.g. (a) Tektronix logic analyser connected via a specialised interface box to the
backplane of an SMP, or (b) Gigabit Ethernet trace instrument
2. What were you saying about it?
<BAC> About the whole slide ? That these are the three flows, and notice that while they
are complimentary, they are not integrated into a Grid information system.
3. Does ‘db’ mean R-GMA or only the idea that this kind of data is stored persistently in a database?
<BAC> Our present (cluster-based) SANTA tools use either SQL Server or MySQL. R-GMA can
in theory use any RDBMS, but presently only hooks up to MySQL, so we will use MySQL via
the R-GMA. In other words, dB means that this data is stored persistently in a database.
