TODO

• Build from source (Done)

Information

• document binning/operators

Web UI

• change logo on UI
• UI regex/wildcard pause/resume
• UI details when PVTypeInfo (otherwise abort)
• delete/edit archiver integration
• Add a link/page for version number of all components

Operators

• Operator combining?
• Testing operators
• post-processing in ETL to decimate (DB post proc.)
• add dead-band post-procsser
• operators give last sample before start time?

Other

• CAJ search algorithm
• appl. Monitoring
• Policy (event/storage rate)
• file converter (cosylab)
• SQL writing? (BPL for adding w/o archiving?)
• PB file invarients (monotonic
• xmlrpc query startegy
• Engine performance tuning

• of PB serialization threads

• of CAJ I/O threads

Problems

• Fix init script ordering (shutdown engine before etl)
• quick-chart
• xf23id-ca Webapp is not in correct state
• PV name search time
• Where do invalid time stamps come from? (MD)

Troubleshooting

CA protocol disector https://github.com/mdavidsaver/cashark

tcpdump -i eth4 udp dst port 5064

Requirements for the dead band operator

Intent is mimic ADEL; targeted at decimation

We have some notion of a "last" value that was written out.

1. The very first sample we get we write out and that becomes the last value.
2. Diff = Math.abs(current value - last value)
3. If Diff >= ADEL 3.1) Write out value 3.2) Update last known value
4. If either current value or previous value is NAN/INF, unconditionally write out current value and update last known value
