In this version of Tachyon Server, some installers do not support the LOGPATH property and the logs folder is not configurable during installation.
Each component has a configuration file in the Tachyon Server installation folder structure, which contains log configuration details. Defaults are:
Filepath %ALLUSERSPROFILE%\1E\<product>\ where product is Tachyon, SLA Platform, and Catalog
Filename as shown in the table above.
Maximum size 10MB (2MB for Switch logs).
2 rollover files numbered 1 to 2 with the rollover number included as n.log (5 rollover files for Switch logs).
Date and timestamps are UTC to help troubleshooters synchronise logs on systems in different timezones.
Switch logs have the following names:
The first Switch installed will typically have a log filename Tachyon.Switch_A.log
Other Switches on the same server will have different letters appended. The letter is derived from the ID in the SwitchConfiguration table, where the letter is modulo 26 of the ID minus 1, for example ID=2 is A and ID=6 is E.
The log filename will be unique on a server, but there may be the same named log on a different server.
A Switch will continue to use the same log, unless the SwitchConfiguration table is modified so that a different ID is used.
If you see a Tachyon.Switch.log without a letter appended, this is a special case where a Switch cannot find its correct configuration, and has fallen back to using the template * row which has ID=1. In which case you will need to troubleshoot how that happened.
Rollover logs have numbers appended, for example Tachyon.Switch_A.1.log, up to a default maximum of 5.
