How can I direct messages from mac console.app to a log file?
I'm trying to complete a bash script to capture if an external webcam is active in a video conference session. Some users will switch the camera to the built-in MAC camera. When this happens I want to trigger a set of events.
Things tried: reviewed the console.app to look for patterns on when the switch occurs in a user test & discovered messages indicating when the facetime camera changes state. I found this
I thought I could simply grep these message from the console.app but it seems to be easier said than done. I thought i could find the msgs in one of the console report files but When I look at the various reports on the console, i'm not finding a report that contains the messages above. How can I direct messages from console.app to a log file versus manually copying and pasting the info from the console?or point me to a direction? Am I missing something?

What is the best practice to allow a 3rd party health monitoring app to read the messages file. Since messages is a system file and is owned by root the app cannot read the file.

fs_messages
FS_MESSAGES(1) AFS Command Reference FS_MESSAGES(1)NAME
fs_messages - Sets whether the Cache Manager writes log messages
SYNOPSIS
fs messages [-show (user|console|all|none)] [-help]
fs me [-s (user|console|all|none)] [-h]
DESCRIPTION
The fs messages command controls whether the Cache Manager displays status and warning messages on user screens, the client machine
console, on both, or on neither.
There are two types of Cache Manager messages:
o User messages provide user-level status and warning information, and the Cache Manager directs them to user screens.
o Console messages provide system-level status and warning information, and the Cache Manager directs them to the client machine's
designated console.
Disabling messaging completely is not recommended, because the messages provide useful status and warning information.
OPTIONS -show (user|console|all|none)
Specifies the types of messages to display. Choose one of the following values:
user
Send user messages to user screens.
console
Send console messages to the console.
all Send user messages to user screens and console messages to the console (the default if the -show argument is omitted).
none
Do not send any messages to user screens or the console.
-help
Prints the online help for this command. All other valid options are ignored.
EXAMPLES
The following command instructs the Cache Manager to display both types of messages:
% fs messages -show all
PRIVILEGE REQUIRED
The issuer must be logged in as the local superuser root.
