Does anyone recommend a good GUI for viewing Linux log files on Windows or Mac? I'd pay for an OSX-Console-like app that'll connect to a remote Linux distro and allow easy browsing/searching of /var/log/, or any paths you add to it.
The better architecture is to bring logs to a centralized place and do analysis on them that way. Your GUI tool doesn't scale for real work, particularly if the machine you are investigating logs upon has been compromised or is broken.
You could setup splunk free (or one of the OSS clones like logstache or greylog2) on the Linux host and use that web interface for visualizing and searching the logs.
I highly recommend Logstash and Kibana. The setup might be a little more complex then some would desire (but by no means is it difficult and both have solid docs), but the two are pretty powerful tools.
