This might not the best method but I used the Log show command to access the unified logs.
And then directed this to a file. So I use this to monitor the camera status.

"expr: 0402-050 Syntax error." My problem is I am not able to re-direct this error to the log file. Its is getting... (4 Replies)

Hi guys,

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.

sysdiagnose
sysdiagnose(1) BSD General Commands Manual sysdiagnose(1)NAME
sysdiagnose -- gathers system-wide diagnostic information helpful in investigating system performance issues
SYNOPSIS
sysdiagnose -h
sysdiagnose [-f results_directory] [-A archive_name] [-V volume_path] [-n] [-k] [-F] [-S] [-u] [-Q] [-b] [-p] [-P] [-d] [-D] [-r] [-R]
[process_name | pid]
DESCRIPTION
The sysdiagnose tool gathers system diagnostic information helpful in investigating system performance issues. A great deal of information
is harvested, spanning system state and configuration. The data is stored /var/tmp directory. sysdiagnose needs to be run as root. To cancel
an in-flight sysdiagnose triggered via command line interface, press Ctrl-. sysdiagnose is automatically triggered when the following key
chord is pressed: Control-Option-Command-Shift-Period.
What sysdiagnose collects:
o A spindump of the system
o Several seconds of fs_usage ouput
o Several seconds of top output
o Data about kernel zones
o Status of loaded kernel extensions
o Resident memory usage of user processes
o Recent system logs
o A System Profiler report
o Recent crash reports
o Disk usage information
o I/O Kit registry information
o Network status
o If a specific process is supplied as an argument: list of malloc-allocated buffers in the process's heap is collected
o If a specific process is supplied as an argument: data about unreferenced malloc buffers in the process's memory is collected
o If a specific process is supplied as an argument: data about the virtual memory regions allocated in the process
OPTIONS -h Display help.
-v Enable verbose mode to display the container information as it executes.
-f results_directory
Specify the directory where the results will be stored. The default results directory is /var/tmp.
-A archive_name
Specify the name of the archive created in the results directory.
-V volume_path
Specify the root volume for sysdiagnose to run on.
-n Do not tar the resulting sysdiagnose directory.
-k Do not remove the temporary directory.
-F Get feedback data.
-S Disable streaming to tarball.
-u Disable UI feedback.
-Q Skip footprint.
-b Do NOT show the resulting archive in a Finder window upon completion.
-p Collect only time-sensitive data. Disregards previous -d or -r flags.
-P Do not collect time-sensitive data.
-d Collect only log data. Disregards previous -p or -r flags.
-D Do not collect log data.
-r Collect only log archive. Disregards previous -p or -d flags.
-R Do not collect log archive.
process_name | pid
If a single process appears to be slowing down the system, passing in the process name or ID as the argument gathers additional
process-specific diagnostic data. Specify only ONE process at a time -- specifying multiple processes is not supported.
EXIT STATUS
sysdiagnose exits with status 0 if there were no internal errors encountered during the diagnostic, or >0 when an error unrelated to external
state occurs or unusable input is provided by the user.
