I would like monitor a large log file (close to 1 GB) for errors. I want this to be close to real time (few seconds delay is fine). My plan is to use
tail -f | grep. Is there any performance issues with using such a method when running it over a long time, say from zero bytes to 1 GB? Are there any standards practices used for such a monitoring. Note that I would like to do this using standard unix commands available on Solaris 10.
If that is possible, my file even rolls over and I have one more problem to sort out :). using
tail -F (
-follow=name) is not an option for me because
-F is not supported in the server I want to run this on. My plan is to use a script which will start this tail and poll on to find if the file is rolled over. If yes, then kill the tail and restart it. Any better approach?
