# Bento |

Bento received a new feature, it is now able to report if the remote |
|
hosts are up-to-date, how much time passed since their last update, and |
|
if they are not up-to-date, how long passed since the configuration |
|
change. |

Bento git project repository |

|
As Bento is using SFTP, it's possible to deposit information on the |
|
central server, I'm currently using log files from the builds, and |
|
compare this date to the date of the configuration. |
|
|
|
This will be very useful to track deployments across the fleet. I plan |
|
to also check the version expected for a host and make them report |
|
their version after an update, this should possible for flakes system |
|
at least. |

I pushed a new version affecting all hosts on the SFTP server, and run |
|
the status report regularly. |
|
|
|
This is the output 15 seconds after making the changes available. |
|

This is the output after two systems picked up the changes and reported |
|
a success. |
