The DIPAZ (Data Storage Indexing and Compressing) tool is a Windows service that reads the trace files and creates trace files and PCAP (Positioning Calculation Application Part) files. DIPAZ also deletes trace files before the disk gets full, reads Quality of Service (QoS) data and stores them in a SQLite database.
DIPAZ is a Windows Service that will be started automatically on Windows startup and runs continuously on the Windows PC. DIPAZ will constantly monitor the raw trace file directory, looking for new raw trace files being uploaded via FTP/SFTP from the Lotus Sametime Unified Telephony Persistent Reader or FTP/SFTP scripts.
The DIPAZ process has no user interface.
When a new raw trace file is detected, DIPAZ will:
- Parse the binary trace data and extract key info such as DNs, call-ids, and error info.
- Create a PCAP file for all external messages
- Compress the file using GZIP
- Parse the phone and/ or QoS file/database and store extracted QoS info in SQLite database indexed by call-ID
System Specific Information
The continuous trace software DIPAZ is hardware and Windows (XP, 2003 and 2008) version independent. There is no dependency on service packs, 32/64 bit and drivers.
When the file size reaches 20 MB or the end of the day is reached the index file is closed and a new index file is opened.
Once the trace file is successfully parsed it is compressed, saved to disk and the original trace file is deleted.
The trace files are stored in a directory tree by day / hour / node ID.
The index file is stored directly in the day directory.
Because trace file compression is executed by default on the Lotus Sametime Unified Telephony, DIPAZ needs to uncompress the trace files before the indexing.
