That's possible in linux using the inotify(7) interface.
A simple sample command line tool using that is inotifywait(1). Example:
inotifywait -mr /tmp
will print all kind of events (files opened, created) that happen inside the /tmp directory. The -r option tells it to set watches recursively on subdirectories, and the -m option not to exit after the first event.
The set of events watched can be restricted with the -e option: eg. -e create,delete to only print info about directory entries that were created or deleted.

The simplest (for me) way is to use the auditd daemon (man page) after installation. You can monitor file operations in /var/run directory by starting the daemon and adding this directory to be audited:
auditctl -w /var/run/ -p rw -k var-run-pids
With this command you can check the log of daemon where most of info is written:
tail -20 /var/log/audit/audit.log
With this command you can search in audit log for particular events:
ausearch -f /var/run
You can send messages thusly (from the man page of auditctl):
-m text
Send a user space message into the audit system.
This can only be done if you haveCAP_AUDIT_WRITEcapability
(normally the root user
has this). The resulting event will be the USER type.
