I’ve disappeared from this blog in the recent month but I’ve not been idle: I’ve implemented initial support for LogStore in the Premium Edition of syslog-ng.
LogStore is a binary log file format, in semantics very similar to a plain log file. But the format allows much more:
- on-line compression via gzip,
- encryption via AES and X.509 certificates,
- integrity protection via hmac-sha1.
And furthermore: it is indexed based on time, and it is quite efficient to look for a specific time range in GBs of log data. I’m quite satisfied, although there are some more work left to be done, for instance the query interface for the time based indexing is not completed.
In use it is quite simple: replace the “file” destination with “logstore” and you are done. More or less the same amount of options are supported: macro based file names, template based formatting, etc.
I’m still pondering with the idea of storing the complete internal representation of the logrecord in serialized form, so it’d be possible to perform template() based formatting in off-line mode.
This code will be released as an experimental part of syslog-ng PE 2.1 and will be finalized in syslog-ng PE 2.2.
