System login dataset
editSystem login dataset
editThis functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.
This is the login dataset of the system module.
Implementation
editThe login dataset is implemented for Linux only.
On Linux, the dataset reads the utmp files
that keep track of logins and logouts to the system. They are usually located
at /var/log/wtmp (successful logins) and /var/log/btmp (failed logins).
The file patterns used to locate the files can be configured using
login.wtmp_file_pattern and login.btmp_file_pattern. By default,
both the current files and any rotated files (e.g. wtmp.1, wtmp.2)
are read.
utmp files are binary, but you can display their contents using the
utmpdump utility.
Example dashboard
editThe dataset comes with a sample dashboard:
