At Keck our IOC console ports are all connected to terminal server ports and, typically, there is a telnet session to each of those ports that are ‘tee’d to a log file. The reason for this is that software bugs (typically in drivers or callbacks) will often cause VxWorks failures which may generate messages that do not get into the iocLog files. I suspect it should be easy to adapt the iocConsole/screen software to deal with the terminal server sessions (thanks for that info).

 

Cheers,

Al

Subject: Serial port access and loging services for IOCs?

 

Here at SNS we have lately had problems with IOCs crashing without leaving any trail for analyzing what the problem was.  We have our own home grown procServe and we are looking into the iocConsole/screen software that SLAC is using.  We are different from SLAC in that we use Digi port servers with a driver on one of the linux servers that maps port server ports into local /dev/ttyXXNNN devices.  We just use 'cu' to open a serial port.  IocConsole does not support that but making it do so would not be hard I don't think.

 

Looks like a modified iocConsole is our best option but before we commit to it we thought we out to see what others are doing to capture the last few lines of terminal activity from running and crashed hard IOCs.

 

Any ideas?
