 Checking your pump-loop.log is a great place to start anytime you are having looping failures.  Your error may not be in the pump-loop, but the majority of the time, you'll get a good head start on the issue by looking at the logs first. So, develop a good habit of checking the pump-loop log to get to know what a normal log looks like so that when a real error appears, you can easily see it as out of place and needing to be addressed.

+These logs and other files are things you may frequently access. There are shortcuts built in to help you more easily access key files on the go. The `l` you type for logs is an example of one of these shortcuts - it's actually a shortcut for the full command `tail -F /var/log/openaps/pump-loop.log`. Here are some other shortcuts:

+ l => tail -F /var/log/openaps/pump-loop.log
+ autosens-loop => tail -n 100 -F /var/log/openaps/autosens-loop.log
+ autotune => tail -n 100 -F /var/log/openaps/autotune.log
+ ns-loop => tail -n 100 -F /var/log/openaps/ns-loop.log

+To use these shortcuts, just type in the phrase you see on the left - i.e. `edit-wifi` and hit enter.
