Subject: proposal: IOC logger

Salut, EPICS folks!

We have some proposal about IOC logger..

Problem background
------------------

  - Seperated log files to record the messages from different IOC's. 
    But, some sites will continue to prefer to keep messages from several 
    IOC's in one file.

  - Run time reconfiguration of iocLogServer.

  Proposal:
  --------
  - Use one configuration file to specify all parameters for the server.

  - One chapter should consist of information where messages from particular
    must be saved:

    <IOC name>|          <full path>  |<size limit>|<versioning>|<mail address>
    ...........................................................................
    heraVME00 |/.../heraVME00_log.text|1000000     | Y          |claus@desy.de
    heraVME01 |/.../heraVME00_log.text|1000000     | Y          |claus@desy.de
    heraVME02 |/.../heraVME02_log.text|4000000     | Y          |csuka@desy.de
    heraVME03 |/.../heraVME03_log.text|239093      | N          |
    ...........................................................................

   * msg from heraVME00 and heraVME01 will be saved in ONE file

  - To add a new variable "EPICS_IOC_LOG_CONFIG_FILE" which should keep
    full path to the configuration file.

  - Send the signal SIGHUP (kill -1 <pid>) to iocLogServer to forse it to 
    read config file again a make inner reconfigurations. (to be discussed)

    In start time:

    1. iocLogServer <path to config file> 

    2. If ``config_file'' does not specify in command line then read 
	system env. variable EPICS_IOC_LOG_CONFIG_FILE. 
   
    3. If env. does not exist, then use today approach.



Problem background
------------------

   - Once the file is written fully, we need a possibility to inform 
     the system manager about it and stop writing.

  Proposal:
  --------
   - IOC log sever will check itself whether a new month has started and 
     crate new log file /xx/yy/mm/logfile.

   - Send a mail to the system manager to tell about this.
